Description
Setpoints Sync/Load ctrl: GCB open level and GCB open
del are related to genset unloading too.
Cooling
H
Engine is cooling down
Emerg man
H
Emerg. manual binary input function is active
Not ready
H
Genset is not ready to start. Controller is either in OFF
mode or any 2
nd
level alarm is in controller alarm list.
ExcitationON/ ExcitationOFF
H
It indicates activation/deactivation of excitation in case of
configuration the SUS sequence function.
Wrn SUSminPwr
A+H
It indicates that require power from the gen-sets with
activated LBO:ReadyToExcite was not achieved (require
power is set by setpoint #SUS min power).
SUS seq blck
A
Alarm indicates that SUS sequence is required, but
setpoint Gear teeth is equal 0. (SUS sequence require
pick-up sensor for correct function).
SUSseq break-1
H
MCB is closed (in SPTM application).
SUSseq break-2
H
MCB is open (MCB feedback is not active) OR Mains
voltage is higher than 1/3 of setpoint Basic
settings:MainsNomV
(in SPI application).
SUSseq break-3
H
Bus voltage is higher than 1/3 of setpoint Basic
settings:BusNomV (in MINT application).
SUSseq break-4
H
GCB was not closed during the Prestart Time count down.
SUSseq break-5
H
Setpoint SUS control:ExcitationCtrl=EXTERNAL. The LBI:
SUSexcitBlck was not activated before engine start OR it
was deactivated before the LBO: ReadyToExcite activation

This alarm may be displayed as Wrn or Sd alarm type. Alarm type depends on Protection upon
module failure setting in Modules card in GenConfig. Available settings are: No Protection,
Warning and Shutdown.

See setting of Force Protect functions on the PLC card in GenConfig to find out what PLC State x
texts were changed to.

Hold Enter and push Esc to enter the Info screen 1. Push the right arrow → to enter Info screen 2
to read IDch and Dngl strings or controller serial number and Password Decode number
(Pwd.Dec.).

You can exchange battery by yourself, but ComAp would not be responsible for controller
damage caused by battery exchange then. See our AS08 – Battery exchange process r1
manual for instructions, if you would like to exchange controller battery by yourself.

See Al./Hist. msg column on Protections card in GenConfig to see customized alarm messages
which are related to configurable protections.

Speed control related regulation loops are part of the Sync/Load ctrl group of setpoints:
Frequency regulation loop: Freq gain, Freq int setpoints
Angle regulation loop: Angle gain setpoint
Load regulation loop: Load ramp, Load gain, Load int setpoints
Load sharing loop: LS gain, LS int setpoints
7
Voltage control related regulation loops are part of the Volt/PF ctrl group of setpoints:
Voltage regulation loop: Voltage gain, Voltage int setpoints
Power Factor regulation loop: PF gain, PF int setpoints
VAr sharing regulation loop: VS gain, VS int setpoints
8
Alarm is related to Generator voltage terminals connection
9
Alarm is related to Mains (Bus) voltage terminals connection
