If
Pwr management: Pwr management is DISABLED, the closed input requests the engine to start
regardless of the load reserves.
Gen-set is running both in mains parallel or island parallel (depends on mains condition). Reaction on input
state change is delayed by setpoints #SysAMFStrtDel / #SysAMFStopDel in island mode, by 1 sec in mains
parallel mode (= input MCB feedback active).
Emergency stop
If the input is activated, engine shutdown is immediately issued. It has a character of a “Shutdown” -
protection type, however some special behaviour follows in the case of its activation:
Sd override
If the input is closed, all 2
nd
level protections are disabled to allow engine run in an emergency situation, e.g.
sprinkler devices power supply.
All protections are shown in Alarmlist and recorded into History, but the controller doesn’t stop the engine
due to their occurence. If the input is deactivated and some protections are still active or not yet reset, the
controller starts to take these protections into account and consequently stops the engine.
Hint:
All 2
nd
level protections are locked out, except of:Emergency stop
Emerg. manual
The controller behaves like when switched to OFF mode if input is closed. Opens all binary outputs Fuel
solenoid, Cooling pump signals, etc... except:
Stop solenoid output does not close.
The output terminals that are configured with inversion are closed.
Detection of "running engine" condition and subsequent alarm message "Sd Stop fail" is blocked. The
controller shows "Emerg Man" state and the engine can not be started. Generator current and power
(energy) measurement is active in this mode, regardless of the actual state of the engine.
After the binary input EMERG. MANUAL is open again, the controller recovers to previous mode and
behaves according to the actual situation. Should the engine run and any of the conditions to start the engine
was active, it will keep the engine running.
Function is active in any controller mode and activation of this input is written to history.
Hint:
The function is intended especially for Marine gen-sets which are supposed to be started manually while the
controller has no power supply. To recover successfully from this state, only the signals Stop solenoid, GCB
ON/OFF coil should be used for engine and breaker control, as the other outputs are continuous active
during engine run (e.g. Fuel solenoid) and it is not possible to switch them between more control sources.
Load res 2 …4
If the input LOAD RES 2 or 3 or 4 is closed, the setpoint set Pwr management: #LoadResStrt X +
#LoadResStop X (#%LdResStrt X + #%LdResStop X) will be selected. Higher index has higher priority when
more these binary inputs are closed together. When not configured or not active, setpoint set
#LoadResStrt
1 + #LoadResStop 1 (#%LdResStrt 1 + #%LdResStop 1) is used.
Hint:
All controllers operating in Power management must have the same Load reserves selected.
It is possible to use Virtual periphery to share the signals between more controllers on the CAN bus. In such
case one controller is a server which physically has the signals connected and other controllers get these
signals via CAN bus.
Setpoint set selection depends on the #Pwr mgmt mode – if set to ABS (kW or kVA), #LoadResStrt X type
setpoints are active, if set to REL (%), #%LdResStrt X type setpoints are active.
MinRun power 1 …3
When binary input MinRun power 1 or 2 or 3 is closed, the corresponding setpoint Pwr management:
#MinRun power 1 or 2 or 3
is selected. Higher index has higher priority when more these binary inputs are
closed together. When not configured or not active, minimal running power is 0, i.e. the system works only
based on Load reserves.
Hint:
All controllers operating in Power management must have selected the same MinRun power input.
