When the liquid level of the
external sensor falls below the
set value, “Low Fuel Level” timer
is initiated. (this only concerns
fuel level sensor and does not
concern low fuel level warning
signal via configurable input port)
Use for setting the maintenance
interval.
It can be customized as Temp.
sensor, OP sensor, Fuel level
sensor and Config. sensor curve.
Note 1, if “high temperature inhibit” is configured, or set auxiliary input as “inhibit
high temperature stop” and this input is active, when temperature is higher than the
preset value, or high temperature alarm input is active, controller will send warning
signal only and not stop the unit.
Note 2, if “low oil pressure inhibit” is configured, or set auxiliary input as “inhibit
low oil pressure stop” and this input is active, when oil pressure is lower than the
preset value, or low oil pressure alarm input is active, controller will send warning
signal only and not stop the unit.
Note 3, if “3P3W” is selected, maximum shutdown threshold of “Mains Over
Voltage” and “Gens Over Voltage” can be set as 620V; when select others, maximum
shutdown threshold can be set as 360V.
Note 4, Multiplex Input can be set as “auxiliary input” or “level sensor”; if one of
them is set successfully, then the corresponding items are active. For instance, if set
“Multiplex Input 3” as “Auxiliary Input”, the related configuration items of auxiliary input
3 are active; if set “Multiplex Input 3” as “Level Sensor”, the related configuration items
of level sensor are active;
