22 RAMP @ MIN,CB DELAY(SEC) (monitor)
The time delay the load/unload ramp is at minimum value and the generator KW
has not reached the unload KW trip level.
23 INHIBIT MIN. CB DELAY *FALSE (TRUE, FALSE)
Set this value to TRUE to will allow **22 RAMP @ MIN. CB DELAY** to be
inhibited. This means that if the Unload Discrete Input is set to Unload and the
the load ramp goes to zero, the breaker will not open, even after the **22 RAMP
@ MIN. CB DELAY** has expired. An operator will have to manually open the
breaker. Set this value to FALSE to allow the **22 RAMP @ MIN. CB DELAY** to
be used.
R**ANALOG OUTPUT SETTINGS**
This section sets the parameter to be sent to the analog output driver and the
desired scaling of the output.
01 ANALOG OUTPUT SEL (1-10) dflt = 1 (1, 10)
Select one of the following parameters for 4
–20 mA output at terminals 16,17,
and 18.
1. Engine Speed
2. Speed Reference
3. Fuel Demand %
4. Unit Load %
5. System Load %
6. Analog Input #1
7. Analog Input #2
8. Speed Reference Bias
9. Baseload Reference (kW)
10. Misfire RPM
02 ANALOG OUTPUT SELECTION (monitor)
Displays the analog output selection.
03 4 mA OUTPUT VALUE dflt = 0.000 (-200.00
–200.00)
Adjusted for the value of the displayed parameter when the analog output will be
4 mA. This value should be set to the zero speed, or the minimum value of the
readout.
04 20 mA OUTPUT VALUE dflt = 900.000 (-200.00
–32000.00)
Adjusted for the value of the displayed parameter when the analog output will be
20.0 mA. This value should be set to the rated speed, or the maximum value of
the readout.
05 ANALOG OUT 1 (%) (monitor)
Displays the analog output %, 0% is 4 mA, and 100% is 20 mA.
S**RELAY AND ANOUT TESTS**
This section allows the operator to test the relay driver outputs and the analog
outputs by artificially forcing its signal. The engine must be shut down at
minimum fuel. If the test is enabled, the actuator output will be held to minimum.
01 ENABLE MANUAL DRIVR TEST dflt = FALSE (TRUE, FALSE)
When the engine is at zero speed and minimum actuator output tune this to
TRUE. The status below will read ‘Test On’
