GCM-A Initialization
Apply system power to the GCM-A. The GCM-A DISPLAY PANEL will respond with (a) all
discrete LED’s lit; (b) all segments of the AMBIENT and GENERATOR bar graphs lit; and (c)
all pixels of the LCD display on.
After a delay of two seconds, (a) all discrete LED’s, except the AC POWER, SYSTEM
TROUBLE and FLOW LED’s, will turn off; (b) all segments of the AMBIENT and
GENERATOR displays will turn off; and (c) the display will echo the results of cold start
initialization:
· “GCM-A Ver 1.7B-8”
· “CHECKSUM OK”
· “POWER OK”
· “RELAY TEST …”
· “… PASSED”
· “STARTING …” will flash for two seconds;
· “ROTARY VALVE …”
· “… PASSED”
· “VACUUM OK”
· “SAMPLE LINE ...”
· “… PASSED”
· “GEN SOLENOID ...”
· “… PASSED”
· “AMB SOLENOID ...”
· “… PASSED”
· “AMB FLO=14.0 LPM”
· “GEN FLO=14.0 LPM”
· “WATER OK”
· “END DIAGNOSTICS”
“NORMAL OPERATION” will flash for two seconds; the GCM-A will begin normal operation
and the display will read “GCM-A by E/One.”
