P632  ‑303  ‑403/404  ‑605 Release: 2004-04-30

Hardware

The Ethernet communication module is available.

The new hardware variants now offer, per ordering option, additional operating thresholds for the binary signal inputs:

▪	>18 V (standard variant) (no order ext. No.)
▪	>90 V (60...70% of VA,nom = 125...150 V) (Order ext. No. 461)
▪	>155 V (60...70% of VA,nom = 220...250 V) (Order ext. No. 462)

Installation of the standard variant is generally recommended if the application does not specifically require such binary signal inputs with higher operate thresholds.

Diagram

The updated connection diagrams now include the interfaces for the Ethernet communication module:

▪	P632 ‑403 (for 40TE case, pin-terminal connection)
▪	P632 ‑404 (for 84TE case, ring-terminal connection)

Software

UCA2

Initial implementation of the UCA2 communication protocol.

Extension to the expanded spontaneous signaling range. In addition, GOOSE messages and fault transmission are now supported.

DIFF

P632  ‑304  ‑403/404  ‑606 Release: 2005-05-09

Hardware

The new hardware variants now offer, per ordering option, additional operating thresholds for the binary signal inputs:

▪	>73 V (67% of VA,nom = 110 V) (Order ext. No. ‑463)
▪	>146 V (67% of VA,nom = 220 V) (Order ext. No. ‑464)

Installation of the standard variant is still generally recommended if the application does not specifically require such binary signal inputs with higher operating thresholds.

An optional processor board with a DSP coprocessor is now available. This coprocessor provides a better overall performance of the supplementary functions of the device.

The coprocessor is required for the use of the new current transformer supervision function (CTS).

Software

SFMON

The configuration table of the user defined alarm condition has been extended by the instantaneous and timed outputs 30…32(t) of the programmable LOGIC:

▪	(098 053) SFMON: Output 30 ~ (042 090) LOGIC: Output 30
▪	(098 054) SFMON: Output 30 (t) ~ (042 091) LOGIC: Output 30 (t)
▪	(098 055) SFMON: Output 31 ~ (042 092) LOGIC: Output 31
▪	(098 056) SFMON: Output 31 (t) ~ (042 093) LOGIC: Output 31 (t)
▪	(098 057) SFMON: Output 32 ~ (042 094) LOGIC: Output 32
▪	(098 058) SFMON: Output 32 (t) ~ (042 095) LOGIC: Output 32 (t)

These logic outputs are included in the warning signals by setting SFMON: Fct. assign. warning and they are also recorded in the monitoring signal memory.

These signals can be used to create an alarm signal under complex application conditions. This signaling has no influence on the device's operation (i.e. no warm restart or blocking).

Addendum:

As of version –605 the “memory function” for the warning signal memory may be set. After the associated timer stage has elapsed, a renewed occurrence of a warning is processed the same way as if it where a first occurrence.

COMM1

Bug fixing in the COURIER protocol:

Upon activation of COURIER protocol a warm restart of the device was initiated.

Bug fixing:

▪	IEC 60870-5-101: Support of the 7-byte time tag length has been corrected: (003 198) COMM1: Time tag length = 7 Byte
▪	IEC 60870-5-101: Transmission of negative cyclic measured values has been corrected.
▪	IEC 60870-5-101: Acknowledgment of the general scan command has been corrected.
▪	IEC 60870-5-101: Signals in the general scan are now transmitted correctly without a time tag.
▪	IEC 60870-5-101: Command rejections issued internally by the protection device (between the processor module and communication module) are no longer signaled by the communication interface.
▪	IEC 60870-5-101: Commands are now transmitted correctly, even when the ASDU address length is 2 byte: (003 193) COMM1: Address length ASDU = 2 byte

FT_RC

The recording duration for binary tracks is now limited to 1 minute in order to prevent recording of endless events.

MAIN

Priority control of clock synchronization is now settable.

Positive- and negative-sequence currents from all ends are now continuously calculated and displayed as measured operating data (primary and per-unit values).

OL_RC, FT_RC

Overload and fault recording now have a joint and complete list of possible entries (merged list of all previous signals).

In practice it became apparent that limitations with regard to possible entries in both recording memories would bring no advantages but make analyzing more difficult, as both recording memories could be open at the same time (e.g. a thermal overload situation could lead to a loss of insulation which would cause a fault).

DIFF

The minimum setting value for the characteristic gradients m1 and m2 have been modified to 0.10 (previously 0.15).

The starting condition for the saturation discriminator was modified so that the DIFF protection testing may now be carried out again with conventional test sets (which do not provide correct transient signals).

Along with the new CTS function, an additional threshold, (080 000) DIFF: Idiff>(CTS) PSx, is provided in order to de-sensitize differential protection in case there is a fault in the CT's secondary circuit. For more information about this feature please refer to CTS description.

Bug fixing:

▪	In some cases the overreaching inrush stabilization function did not operate properly. In addition the signal from the inrush stabilization was sometimes immediately reset when a differential protection trip was issued.

REF_x

If the new current transformer supervision (CTS) function is used, the ground fault differential protection function associated with the faulted end was blocked when a CT fault was detected. For more information about this feature please refer to CTS description.

CTS

First implementation of a current transformer secondary wiring supervision which operates fast enough to prevent differential protection from tripping under load in case of a CT failure.

This function can only be used if the new processor board with DSP coprocessor is fitted!

MCM_x

The existing measuring-circuit monitoring functions, based on the phase currents per end, have been enhanced and can now be used to detect broken conductors (“broken conductor protection”) on the CTs' primary sides.

Note: This software version is compatible to all previous hardware versions.

IEC, GOOSE, GSSE

Implementation of the new substation communication protocol per IEC 61850 standard.

Implementation of communication procedures for the exchange of binary information in an Ethernet network section.

Function group GSSE is compatible to previous UCA2-GOOSE. Function group GOOSE is acc. to IEC 61850-GOOSE.

UCA2

The substation communication protocol per UCA2 standard is not supported with this firmware version.

MAIN

Phase reversal logic is now available. This feature allows that the phase reversal switch in motor/generator applications can be located inside the protection zone of the transformer differential relay.

The vector group numbers of the power transformer are now settable per parameter subset. This feature can be used in protection of phase angle regulating transformers.

DIFF

Bug fixing:

▪	The trip signals of the 3 measuring systems (e.g. (041 002) DIFF: Trip signal 1 were falsely instantaneously raised, regardless of the set trip delay time. Note that the (041 075) DIFF: Trip signal was correctly timed.

IDMTx

Accuracy of tripping time is improved, particularly in case of the characteristic “IEC extremely inverse”.

DIFF

Bug fixing:

▪

In versions ‑606 to ‑610 inrush signaling from all three measuring systems was suppressed when harmonic blocking in measuring system 1 was triggered. This was not accompanied by tripping.

Nevertheless there was the possibility of an overreaction (tripping) when an inrush condition was not recognized by one measuring system with the operating mode set to “Not phase-selective” and in an other measuring system the second harmonic component reached a value of approximately between 70% and 130% of the fundamental.

FT_DA

Bug fixing:

▪	The fault data for FT_DA: Fault curr.IY,b p.u. (026 088) were mistakenly calculated on the basis of current IY,a.

P632  ‑306  ‑405/406  ‑611 Release: 2007-03-15

Hardware

As an ordering option for the 40TE and 84TE model versions there is now a variant available with a detachable HMI. The detachable HMI is always supplied with a case width of 40TE.

The detachable HMI provides the following new features:

▪	6 freely configurable function keys as well as 6 freely configurable LED indicators (H18 to H23) each situated next to a function key.
▪	The freely configurable LED indicators (H4 to H16 and H18 to H23) are provided as multi-color LEDs.

Note:

When the local control panel is ordered together with a detachable HMI for hardware version ‑306, it is delivered with function keys and multi-colored LED indicators fitted. Otherwise the earlier local control panel is delivered without having function keys and multi-colored LED indicators fitted.

With hardware version ‑307 and irrelevant of the ordering option, the local control panel is delivered with function keys and multi-colored LED indicators fitted.

Diagram

The updated connection diagrams now include the interfaces to connect the detachable HMI.

▪	P632 ‑405 (for 40TE case, pin-terminal connection)

Software

IEC

Implementation of active monitoring of the communications data links to logged-on clients with the parameter (104 062) IEC: TCP keep-alive timer. This active monitoring now replaces previous passive monitoring by parameter (104 050) IEC: Inactivity timer.

Implementation of an automatic switchover to daylight saving time, activated by parameter (104 219) IEC: Switch.dayl.sav.time. Switchover times for the automatic switch to daylight saving time are governed by the following settings:

▪	(104 220) IEC: Dayl.sav.time start
▪	(104 221) IEC: Dayl.sav.time st. d
▪	(104 222) IEC: Dayl.sav.time st. m
▪	(104 223) IEC: Dayl.sav.t.st.0:00 +
▪	(104 225) IEC: Dayl.sav.time end
▪	(104 226) IEC: Dayl.sav.time end d
▪	(104 227) IEC: Dayl.sav.time end m
▪	(104 228) IEC: Dayl.sav.t.end 0:00+

A second SNTP server may now be applied for time synchronization. Should no answer be transmitted by the first SNTP server the next request is automatically transferred to the second SNTP server (backup function).

▪	(104 202) IEC: SNTP server 1 IP
▪	(104 210) IEC: SNTP server 2 IP

Instead of setting a router address and target network, so as to establish a communication link to a client situated exterior to the local network, now only the setting of the gateway address is required via (104 011) IEC: Gateway address.

Now “unbuffered reports” are available for all logical nodes.

LED

Configuration, operating mode and physical state of the permanently configured LED indicators H1 and H17 are now displayed via configuration parameters and physical state signals.

The new detachable HMI provides the following extended display functionalities:

▪	The operating mode for the LED indicators has been extended by the operating mode LED flashing.
▪	Two differing signals may now be assigned to the freely configurable LED indicators (H 4 to H 16 and H 18 to H 23) to emit either red or green light. If both assigned signals are active the resulting LED color will be 'amber' (yellow).

CBF_x

Implementation of the new circuit breaker failure protection function including a current reset criterion. The number of availabe function groups corresponds to the number of transformer ends, that is for the P632, 2 function groups are available.

LOC

Because of the ordering option “detachable HMI” this additional Device Identification parameter is now available: LOC: Local HMI exists (221 099).

LOC, MAIN

Respective binary signal inputs (if previously unavailable) are assigned to all default reset functions. These binary input functions are now available in the configuration list for the two newly implemented group resetting functions as well as the extended functional assignment for the CLEAR key ('C'):

▪	(005 248) MAIN: Fct.assign. reset 1
▪	(005 249) MAIN: Fct.assign. reset 2
▪	(005 251) LOC: Assignment reset key

Two menu jump lists may now be configured. These menu jump lists make it possible to select individual menu points (i.e. set values, counters, triggering functions, event logs) in a freely definable sequence.

▪	(030 238) LOC: Fct. menu jmp list 1
▪	(030 239) LOC: Fct. menu jmp list 2

F_KEY

The new control panel (HMI) is fitted with 6 freely configurable function keys which may be used either as switches or keys, and are password protected.

Because of this the function group F_KEY “Configurable Function Keys” has been added.

LOC

Bug fixing:

▪	Reset functions configured to the CLEAR key ('C') are now carried out correctly. A system restart could previously occur when the detachable HMI was disconnected.

FT_DA

Bug fixing:

▪	The fault data for differential current and restraining current issued by the ground differential protection function REF_2 are now also calculated correctly when the operating mode is set to “Low imped. / IP,max” (previously they had twice the value).

REF_x

When the differential protection is triggered these functions are now blocked as long as at least one of the following conditions is met:

▪	DIFF: Meas.system 1 trigg. (041 124)
▪	DIFF: Meas.system 2 trigg. (041 125)
▪	DIFF: Meas.system 3 trigg. (041 126)

CBF_x

IEC

The data model of the measured operating values for differential current and restraining current in the functions DIFF and REF_x is now implemented according to the data attributes for the standard WYE, ACT and ACD classes.

Note:

With this implementation, the “phase” measured values from the DIFF protection functions correspond to the measured values of the three measuring systems:

▪	“phSA” = Measuring system 1
▪	“phSB” = Measuring system 2
▪	“phSC” = Measuring system 3

Accordingly the measured values from the REF_x protection functions are modeled as “neut”.

ICD and PICS-MICS-ADL files have been upgraded accordingly.

DVICE

The previous parameter DVICE: Order No. (000 001) has been renamed to DVICE: AFS Order No. (001 000).

LOC

The parameters (005 251) and (080 110) have been renamed to LOC: Fct. reset key (005 251) and LOC: Fct. read key (080 110) without any changes in their functionality.

Now the selection offered for the parameter LOC: Language (003 020) no longer is between, e.g. German, and English but between “Regional language” and “Reference language”. (This will not cause any changes in functionality as the Reference language is US English and the Regional language will depend on the language order option.)

GOOSE

Several GOOSE signals have been added as part of the new control functionality. For a detailed listing see the “Settings” and “Information and Control Functions” chapters.

MAIN

The following menu points are now available for each parameter subset:

▪	MAIN: Vnom prim. end a PSx
▪	MAIN: Vnom prim. end b PSx

The parameter (003 030) has been renamed to MAIN: Device on-line.

Note:

These signal assignment parameters are visible in the data model for 4 circuit breakers. However, for the P632 they can be used only in accordance with the actual number of CBs supported. With the P632, 2 circuit breakers are available.

In order to configure function keys with control functions the following parameters are available which may be assigned to four of the six function keys:

▪	MAIN: Device selection key (006 001)
▪	MAIN: Device OPEN key (006 002)
▪	MAIN: Device CLOSE key (006 003)
▪	MAIN: Local/Remote key (006 004)

The P632 now features the acquisition of debounced binary signals for control functions, and the parameter MAIN: Time tag (221 098).

As part of the control functionality the P632 now features additional parameters:

▪	MAIN: Type of bay (220 001)
▪	MAIN: Customized bay type (221 062)

MEASI

The result of the temperature measurement may now also be read out as the maximum value since the last reset operation (temperature Tmax).

INP

The setting INP: Filter (010 220) is now available for conformity with standard IEC 60255-22-7, class A.

FT_DA

Correction:

The wrong internal timing where the parameter FT_DA: Run time to meas. (004 199) could take on the value “Overflow” has been corrected.

THRM1

Correction:

With the following menu points the step size for temperature values has been reduced from 0.01 to 0.001:

▪	THRM1: Object temp. p.u. 1 (004 205)
▪	THRM1: Coolant temp. p.u. 1 (004 206)

CBF_x

The parameter (056 007) has been renamed to CBF_1: Function group CBF_1 without any changes in the functionality.

The following parameter may now not only be set to an explicit time value but also to “Blocked”:

▪	CBF_2: Delay/fault beh. CB (022 227)

The startup criterion has been modified. After a CBF startup the state of the general trip signal or the external trigger signal are now no longer considered. The CBF will then only reset if the current criterion is met (current values to fall below I< with all three phases) or the CB state is open.

DEV01 ... DEV03

New function groups “External Devices xx” (xx = 01, 02, 03) as part of the implementation of control functions.

ILOCK

New function group “Interlocking Logic” as part of the implementation of control functions.

CMD_1

New function group “Single Pole Commands” as part of the implementation of control functions.

SIG_1

New function group “Single Pole Signals” as part of the implementation of control functions.

▪	V<>: tV< elaps. transient (042 023)
▪	V<>: tV<< elapsed trans. (042 025)

CBF_x

The release condition for the function has been dissociated from the drop-out of the internal trip signal. Therefore the sequence will now only be stopped when a loss of load/undercurrent condition has occurred or when the CB signals that its contacts are open.

Bug fixing:

▪	The time tags for the CBF_1: Ready (038 009) and CBF_2: Ready (043 076) spontaneous signals (according to the communications protocol per IEC-60870-5-10x) and the entry in the operating data memory did not match.

IEC

Bug fixing pertaining to the COMTRADE fault files which a client receives via the IEC 61850 interface:

Stating of “Control Modes” in the ICD file has been corrected. The IEC data model is not affected by this.

Bug fixing:

▪

The automatically generated data file names are now correct with fault numbers exceeding 999. Data file names are issued according to this format:

yyyymmdd_HHMMSS_xxx_rNNNN.eee

With: yyyy = year

mm = month

dd = day

HH = hour

MM = minute

SS = second

xxx = millisecond

r = permanent single character

NNNN = fault number

eee = file extension

In previous versions the dot (.) was overwritten for fault numbers exceeding 999.

▪

The correct number of binary channels is now entered in the COMTRADE configuration file (*.cfg). In the previous version the number of binary channels was given as n*16+1 when, because of the function configuration, n*16 binary information signals were recorded. Therefore values stored in the *.cfg file and the *.dat file did not match.

IEC

The processing times for the control and monitoring of switchgear units between the Ethernet communication module and the main CPU have been reduced.

The data object LN_CFG has been extended in logical nodes Dt1NgsPTOC1, Dt2NgsPTOC1 and Dt3NgsPTOC1.

The AlmGGIO logical node has been extended by the following signals:

▪	Alm5: THRM1: CTA error (039 127)
▪	Alm7: MEASI: PT100 faulty (040 190)
▪	Alm8: MEASI: Overload 20mA input (040 191)
▪	Alm9: MEASI: Open circ. 20mA inp. (040 192)
▪	Alm10: CTS: Operated (updating) (036 099)

The ‘Bl.f.’ data objects are now available in all nodes: PTOC, PTOV, PTUV, PTTR, PTOF, PTUF, RBRF, PVPH. Because of this, the ‘Blocking EXT’ condition has been removed from the ‘MODE’.

The parameter at address (104 232) IEC: Dead band VPP has been renamed to IEC: Dead band V.

Since the corresponding measured values are not provided by the P632, the following addresses have been deleted:

▪	IEC: Dead band VPG (104 233)
▪	IEC: Dead band P (104 235)
▪	IEC: Dead band Z (104 237)
▪	IEC: Dead band ASC (104 239)
▪	IEC: Update cycle energy (104 060)

COMM1

Bug fixing with the use of the MODBUS communication protocol:

Faults can now be read out.

MAIN

Display of the following settings has been limited in accordance with the device function.

Visible in the P632 are:

▪	MAIN: Sig. asg. CB1 open (021 017)
▪	MAIN: Sig. asg. CB1 closed (021 020)
▪	MAIN: Sig. asg. CB2 open (021 061)
▪	MAIN: Sig. asg. CB2 closed (021 060)
▪	MAIN: Device selection key (006 001)
▪	MAIN: Device OPEN key (006 002)

Bug fixing:

▪	The measured operating values for the positive sequence currents are now calculated independently of the DTOC/IDMT protection functions.

DIFF

The starting condition for the saturation discriminator has been enhanced by the addition of a further minimum condition for the restraining quantity with basic filtering. Without this minimum condition, the saturation discriminator could be incorrectly triggered during the test of a characteristic using virtual test signals in the absence of a preload current.

REF_x

Blocking of the REF functions while the DIFF protection (functional enhancement by ‑611 ‑715) has been triggered can now be enabled/disabled using setting parameters.

Furthermore the REF_1: Blocking EXT (019 051) and REF_2: Blocking EXT (019 052) binary signal input functions are now available to allow for a more flexible application of the functions. Since operational readiness is no longer solely dependent on the device setting, its state is also signaled:

REF_1: Ready (019 054), REF_2: Ready (019 055), i.e. REF_x enabled AND NOT blocked.

REF_1

The function has been enhanced so that further ends can be included into the protection reach, e.g. in ground differential protection for autotransformers.

CBF_x

As an option, the loss of load/undercurrent criterion can now also be used with the residual current.

The external function startup may now occur either when only the loss of load/undercurrent criterion is applied or also with the CB contact position scanning criterion.

Bug fixing:

▪	Display problems with the Fault Panel are resolved.

V/f

The setting range for V/f: t at V/f=1.05 PSx has been extended:

▪	Previously: 1.0 s to 1000.0 s in steps of 0.1 s,
▪	Now: 1.0 s to 6000.0 s in steps of 0.1 s.

Similarly, the setting range for V/f: Reset time PSx has been extended:

▪	Previously: 0 s to 10000 s in steps of 1 s,
▪	Now: 0 s to 60000 s in steps of 1 s.

DEVxx

Device identifiers can now be edited. In the “Designat. ext. dev.” parameters the ‘Device Name User’ setting should be selected. Then the text for the device’s name, entered by the user at each of the “DEV-Name User” parameters, will be used as the device’s designation. The maximum number of 4 characters was not changed from the previous permanent default setting.

Parameters:

▪	DEV01: DEV-Name User (218 101)
▪	DEV02: DEV-Name User (218 102)
▪	DEV03: DEV-Name User (218 103)

ILOCK

As the interlock conditions are also transmitted together with reporting in the newly implemented phase 2 of the IEC 61850 communication protocol, it is now a requirement that these interlock conditions are cyclically checked and not, as before, only with the request for a switching operation.

Therefore this new parameter has been introduced:

(221 104) ILOCK: Cycle t interl.check

The cycle time (range from 100 ms to 10 s) is set here, after which a check of the interlock conditions is carried out. As additional processor capacity must be provided for each of these checks it must be ensured that a favorable compromise is found for the cycle time setting value. On the one hand it is desirable to select a cycle time value which is as short as possible so that changes in the interlock conditions are updated without any notable delays, but on the other hand this cycle time value should not be so short that the P632 system will be under too much strain. As the P632 CPU load is dependent on the total number of function groups having been configured it is not possible to suggest a generally acceptable cycle time value.

Bug fixing:

▪	If single-pole signals of function group SIG_1 were active during device startup, this could lead to an aborted initialization of the Ethernet communication module.
▪	During the process of connection with clients that use the “IntegrityPeriod” option, sporadically the MMS communication of the Ethernet communication module would crash without an internal monitoring response to re-establish the functionality. (GOOSE messaging and other communication tasks were not affected.)
▪	Upon receiving a “Cancel” command while a switchgear device is selected, a positive acknowledgement response (“Ack OK”) is sent. Previously, a “Negative ack” was sent.
▪	Reports of events could get lost if too many state changes occurred in a short period of time, especially during secondary injection testing.
▪	If clients did connect to the device immediately after completion of Ethernet communication module startup, this could lead to the temporary erroneous reporting of default values for the external device status (DEVxx) and of the single-pole signals (SIG_1).

The GOOSE Time Allowed to Live (TAL) supervision is enhanced with respect to simultaneous state changes of multiple GOOSE messages.

PC, COMM2

Bug fixing:

The P632 is now fitted with an improved power supply module.

Note that the voltage range has changed for DC input:

▪

For the DC / AC variant, the range is

–	now 60 … 250 VDC / 100 ... 230 VAC
–	(previously 48 … 250 VDC / 100 ... 230 VAC).

▪

For the DC-only variant, the range is

–	now 24 … 60 VDC
–	(previously 24 VDC).

A new communication module (“REB” = “Redundant Ethernet Board”) is now available as an ordering option.

This module can be used for redundant communication via IEC 61850 and may be fitted to slot 2, as an alternative to the other communication modules. The following communication protocols are supported:

▪	SHP (Self-Healing Protocol).
▪	RSTP (Rapid Spanning Tree Protocol).
▪	DHP (Dual-Homing Protocol).

A detailed description of the module and the appropriate network connections is available as a separate document (“Redundant Ethernet Board, Application Guide”).

DVICE

Instead of one parameter for the software version (previously: (002 120) DVICE: Software version) the version numbers ‑6xx and ‑7xx are now separately stored in two new parameters:

▪	(010 167) DVICE: Software version 6XX
▪	(010 168) DVICE: Software version 7XX

Minor version index 7xx is now starting from 700 with each new major version 6xx.

In the communication protocol per IEC 60870-5-103 positive command acknowledgement can now be set to use either single-character E5 (as previous versions) or a short message FT 1.5.

IEC

The number of clients for a report has been increased: An unbuffered report (urcbA … urcbP) can be allocated to max. 8 clients (previously: 1), and a buffered report (brcbA … brcbH) can be allocated to max. 4 clients (previously: 1).

OUTP

Bug notice: With version P63x -650 the test operation of output relays can be executed independent from the off-line state of the device!

MAIN

The previously available parameters (003 039) MAIN: Warm restart und (000 085) MAIN: Cold restart have been relabeled MAIN: Soft Warm restart and MAIN: Soft Cold restart, respectively. They still trigger a restart of the device, but now the hardware tests are not carried out anymore during the startup phase. (This way the restart needs less time.)

For a restart including hardware tests, the following new parameters can now be used:

▪	(010 166) MAIN: Warm restart
▪	(009 254) MAIN: Cold restart

Control (DEVxx, MAIN)

It is possible to download multiple customized bay types without cold restart. Selection parameter has been changed in that way, that any of the downloaded baytypes could be selected through its ID number:

▪	(220 000) MAIN: Type of bay

A new alarm signal for switchgear operating time exceeded is implemented:

▪	(221 110) MAIN: DEV op.time exceeded

This signal will be raised if the command does not reset successfully by switchgear position indication or external run-back signal within set operating time.

LOG_2

There is a new function group LOG_2 (Programmable Logic 2). It is identical to the previously available function group LOGIC, but it offers only four logical equations. These, however, have long-term timers, settable from 0 to 60000 s (= 16 hours, 40 minutes).
