Continued
Cooling time
Runtime of the unloaded gen-set to cool the engine before stop.
Step: 1s; Range: 0 - 3600 s
AfterCoolTime Runtime of engine after cooling pump. Binary output Cooling pump is
closed when the engine starts and opens AfterCool time delayed after
gen-set stops. Step: 1s Range: 0 - 3600s
CoolingSpeed Selects the function of the Binary output IDLE/NOMINAL during engine
Cooling state.
NOMINAL : Cooling is executed at Nominal speed and generator
protections are active.
IDLE: Cooling is executed at Idle speed and generator protections are
switched off.
Hint: Binary output IDLE/NOMINAL must be configured and connected to
speed governor. Engine Idle speed must be adjusted on speed governor.
D+ function ENABLED: The D+ terminal is used for both functions “running engine”
detection and charge fail detection.
CHRGFAIL: The D+ terminal is used for charge fail detection only
DISABLED: The D+ terminal is not used.
Note: Magnetization current is independent of this setpoint value.
Table 4‐16 Engine Protect Setpoints
ECUFreqSelect This setpoint should be used only for Volvo and Scania engines.
ECU Speed Adjust This setpoint should be used only for Volvo and Scania engines.
WTBF Accept RPM The WtBfAcceptRPM delay setpoint will start to count down since
cranking. Controller waits before communicating with the ECU for this
time. This is because the JD engine passes some erroneous RPM signals
during the first 500ms. Step: 0,1s Range: 0 - 3s
Eng prot del During the start of the gen-set, some engine protections have to be
blocked (e.g. Oil pressure). The protections are unblocked after the
Protection del time. The time starts after reaching Start RPM.
Step: 1s; Range: 0 - 300 s
Horn timeout Max time limit of horn sounding. Set to zero if you want to leave the output
HORN open. Step: 1s; Range: 0 - 600 s
Overspeed Threshold for over speed protection.
Step: 1% of nominal RPM; Range: 100 - 150%

Sd Water temp Warning threshold level for ANALOG INPUT 2.
Step: 1 C; Range: Wrn Wtemp - 10000
Wrn Water temp Warning threshold level for ANALOG INPUT 2.
Step: 1 F; Range: Wrn Wtemp low - Sd Water temp
Wrn Wtemp low Warning threshold level for low value on ANALOG INPUT 2.
Step: 1 F; Range: -100 - Wrn Water temp
Water temp Low del Delay for ANALOG INPUT 2 Wrn Wtemp low. Step: 1 s; Range:1-180 s
Water temp del Delay for ANALOG INPUT 2 alarm. Step: 1 s; Range: 0 - 180 s
Wrn Fuel Level Warning threshold level for ANALOG INPUT 3.
Step: 1 %; Range: Sd Fuel Level - 10000
Sd Fuel Level Shutdown threshold level for ANALOG INPUT 3.
Step: 1 %; Range: -100 - Wrn Fuel Level

Batt overvolt Warning threshold for high battery voltage.
Step: 0,1 V; Range: Batt undervolt - 40V
Batt undervolt Warning threshold for low battery voltage.
Step: 0,1 V; Range: 8V - Batt overvolt
Batt volt del Delay for low battery voltage alarm. Step: 1s; Range: 0 - 600 s
NextServTime Counts down when engine running. If reaches zero, an alarm appears.
