Setpoints
Password protection
Any setpoint can be password protected - 7 levels of password is available. The password is a four-digit
number. Only setpoints associated with the entered password level can be modified.
Even though one level may have been set from the front panel, the affected setpoints are not
accessible from InteliMonitor (direct or Modem) until this level is set in IMON.
Setpoints opened from front panel are automatically closed 15 minutes after the last key has been
depressed or when wrong value of password is set.
Any password can be changed once that level password or higher has been entered. The controller
programming (configuration) requires the highest - password 7 level.
ProcessControl
Load ctrl PtM [ BASELOAD / IM/EX / ANEXT BASELOAD /
ANEXT IM/EX / T BY PWR ] (FV)
Load ctrl PtM selects control mode for parallel to mains operation.
BASELOAD
Gen-set is loaded at preadjusted level ProcessControl: Base load.
IM/EX
Gen-set is loaded according to imported/exported power from/to mains to achieve
ProcessControl: Import load.
ANEXT BASELOAD
Gen-set is loaded according to the requested value given by an external device via
Analog input LdCtrl:AnExBld.
ANEXT IM/EX
Gen-set is loaded according to imported/exported power from/to mains to achieve
the requested value given by an external device via Analog input LdCtrl:AnExI/E.
T BY PWR
Gen-set power is changed to keep required temperature, measured via an analog
input.
Force value possibility: Yes
Hint:
For “digital” external load control select mode ANEXT BASELOAD and as the source for LdCtrl:AnExBld
select value ExtValue1-4. This value can be set using a command transmitted e.g. over CAN bus or
ModBus.
Base load [ kW – MW* ]
Required gen-set power when Load ctrl PtM = BASELOAD.
Step: 0,1 kW / 1 kW / 0,01 MW*
Range: OFF, 0,1 kW - Nomin power*
*Note:
The actual setpoint units and range depend on setting of the Power format (see GenConfig manual).
Hint:
If the setpoint Base load is set to lower value than the one given by setpoint Generator protect: Min power
PtM, the gen-set power is limited to Generator protect: Min power PtM.
I/E-Pm meas [ NONE / IM3 CT INPUT / ANALOG INPUT ]
Import / Export measurement selection when one of power I/E modes selected.
NONE
No source for I/E active power measurement available. If selected, power control
defaults to Baseload (BASELOAD, ANEXT BASELOAD, T BY PWR).
