Passwords:
There are several diagnostic modes available in the governor. Access is provided by entering a pass-
word that uses the INC and IDLE switches in a specific sequence.
The Message Center must display [MODE] prior to entering any password.
Governor Self Test:
The Self Test password is:
IDLE INC IDLE INC IDLE INC IDLE INC
This test is capable of determining if there is a problem with the governor that replacement of the gover-
nor display will correct.
Results are displayed in the Message Center as a numeral matching its position in the display.
The Message Center (Test) positions are numbered left to right as follows:
0 1 2 3 4 5 6 7
When the self test starts, the governor checks for the type of output signal present, analog (ANA) or
pulse width modulated (PWM). This is displayed along with the output voltage range if the signal is
analog (Make note of this range. It should vary from ~0.7 to 4.0 VDC). Once this output test is complete
the Message Center will display a results screen. Any X indicates that a particular function has not been
tested.
The Message Center will display X X X 3 - 5 X X for analog or X X X - 4 5 X X for PWM.
Either a ‘3 -’ or a ‘- 4’ are in the 3 and 4 positions dependent on whether the governor is
configured for Analog or PWM output. The 5 in position 5 indicates that the pressure transducer is
transmitting a no pressure signal (expected).
If the pump is engaged, an H (high) will be shown. If the signal is too low, an F (fail) will be displayed.
