107 PRESTART LOW LINE 107-_Percent Line Voltage [VALUE] Check voltage supply.
ALERT VOLTAGE exceeded limit of [LIMIT]*. Check voltage transformers and switch gear.
Consult power utility if voltage is low.
108 PRESTART HIGH LINE 108_Percent Line Voltage [VALUE] Check voltage supply.
ALERT VOLTAGE exceeded limit of [LIMIT]*. Check power transformers.
Consult power utility if voltage is high.
109 PRESTART GUIDE VANE 109_Actual Guide Vane Pos Press STOP button on ICVC and perform
ALERT CALIBRATION Calibration Required Before Startup. Guide Vane Calibration in Controls Test
screen.
Check guide vane actuator feedback
potentiometer.
110 PRESTART HIGH 110_Rectifier Temperature [VALUE] Check that VFD refrigerant isolation valves
ALERT RECTIFIER exceeded limit of [LIMIT]*. are open.
TEMP Check VFD refrigerant cooling solenoid and
refrigerant strainer.
Check for proper VFD cooling fan operation
and blockage.
111 PRESTART HIGH 111-_lnverter Temperature [VALUE] Check that VFD refrigerant isolation valves
ALERT INVERTER exceeded limit of [LIMIT]*. are open.
TEMP Check VFD refrigerant cooling solenoid and
refrigerant strainer.
Check for proper VFD cooling fan operation
and blockage.
*[LIMIT] is shown on the ICVC as temperature, pressure, voltage, etc., predefined or selected by the operator as an override or an alert. [VALUE] is
the actual pressure, temperature, voltage, etc., at which the control tripped.
