2.8.12 Menu 12—Calibration
Menu 12 provides the calibration of the voltage and
current sensing logic. Changing the system voltage or
replacing the main logic control circuit board requires a
calibration adjustment.
Theuser must enable the programming mode to edit the
display.
Connect a meter with a minimum accuracy of 1% to
the generator set output leads to calibrate the
voltage-sensing logic. Configure the generator set
controller for the system operating configuration using
Menu 7—Generator System. Adjust the generator set
voltage using Menu 11—Voltage Regulator, when
required and adjust the frequency at the generator set
governor before making calibration adjustments.
Reduce the voltage regulator gain using Menu 11,
Voltage Regulator until the voltage is stable prior to
calibration.
The user must scale the analog input value in order to
calculate the low/high warning and shutdown analog
values based on a 0--5VDC scale.
ECM engines have user-defined analog inputs
A01--A07. Non-ECM engines have user-defined analog
inputs A03--A07where analog inputs A01 and A02 are
reserved for the engine coolant temperature A01 andoil
pressure A02 displays.
Analog Input A06—Analog Speed Adjust (VSG).
Analog Input A06 may be used for analog speed adjust
whenexternal control of engine speed is desired such as
paralleling applications or closed transition ATS. To
utilize this capability, the input must be calibrated.
Note: For VSG on Analog Aux. Input 06 calibrate:
Volvo: 0.5V=1250; 4.5V=8750
GM/Doosan at 60 Hz: 0.5V=2375; 4.5V=2625
GM/Doosan at 50 Hz: 4.5V=2327; 4.5V=2624
Analog input A07 is the voltage adjustment for
parallelingapplications only. This input adjusts the input
up or down from the value entered in Menu 11, Voltage
Regulator. Calibration is not necessary.
Note: Press the Menu Right →key prior to entering
decimal values where necessary.
Changes to the generator set system parameters
causes a CHECK CALIBRATION display message. If
the generator set system parameters are changed,
verify the controller display calibration by comparing the
results to a known measured value.
