1 defines OFF and MAN modes to be illegal. Warning fault is declared.
Energize Run|Stop:
0 = fuel solenoid is "energize to run".
1 = fuel solenoid is "energize to stop".
Cool After NoLoad?
1 makes the engine cooling off delay mandatory. If 0 is defined, only if the genset contactor was closed
(active IOB1 K#7 relay) at the time genset stop command was issued, the genset enters cooling down
before it stops.
Bat OverVolts S|W:
0 = battery over voltage condition is a shutdown fault.
1 = battery over voltage condition is a warning fault. Fault is declared after 1 second delay.
Recommendation: 0.
Gen UnderVolt S|W:
0 = gen undervoltage fault is shutdown.
1 = gen undervoltage fault is warning.
Gen UnderFreq S|W:
0 = gen phase A under frequency fault is shutdown.
1 = gen phase A under frequency fault is warning.
LowWaterLevel S|W:
In#10 LOW WATER LEVEL fault is: 0 = shutdown, 1 = warning.
Ext. Overload S|W:
In#14 can be connected to an external overload protection relay. When In#14 is active, the gen contactor
immediately opens (ie IOB1 K#7 relay de-energizes). If shutdown option is selected (0) the genset is
shutdown after cooling off period.
GENCON LOW DC S|W:
Dangerously low DC voltage level can be defined as: 0 = shutdown, 1 = warning. Recommendation, enter
0. You may be tempted though to enter 1 to utilize 12V batteries to their end…
The following four parameters define the controller's configuration.
They are described in greater detail in the Applications section.
Generic Configure?
1 selects the generic configuration #0. Having selected this option discards the following parameters:
Parallelin System, Mains Standby ATS, Cogeneration Mode and Check Contactors. The controller's inputs
In#15 and In#16 and output relays K#7 and K#8 get a special meaning, as follows:
In#15 In#16 OPERATION
OFF OFF Synchronizing without load
OFF ON Paralleling with the mains (export quota ramp up/down)
ON OFF Paralleling with other gensets (load-sharing)
ON ON Synchronizing with load
Energized K#7 indicates that the genset is ready for load,
Energized K#8 indicates that the genset runs in sync with the bus/mains,
De energized K#8 while in parallel with the mains indicates PARALLEL LOAD SURGE detection.
Parallelin System?
1 enables the synchronizer, load-sharing, etc.
Mains Standby ATS?
1 = The relay K#8 drives the mains contactor. The transfer of the load from the mains to the genset, and
vice versa, is the controller's responsibility, as is the tradition in Europe: When abnormal AC level is
detected at V4, the genset is started after a time delay, etc. See Standby On and Standby Off. If the
paralleling system is enabled, a soft (synchronized zero-power) transfer is made whenever possible. If not
possible (SYNCHRONIZER TIMEOUT etc.) a standard break → delay → make transfer is made.
0 = The relay K#8 follows K#7 GEN CONTACTOR with an adjustable delay. It can be used to ensure
minimal time for multiple genset paralleling before taking the load. See the (ATS=0) K#7→K#8 delay.
Cogeneration Mode?
If Parallelin System = 1 and Cogeneration Mode = 1 (configurations #4 and #6) the genset runs in parallel
with the mains continuously, maintaining the user COMMAND\EXPORT quotas, as long as In#1 is active.
