11Table 4 — ICVC Alert CodesPRE-START ALERTS: These alerts only delay start-up. When alert is corrected, the start-up will continue. No reset isnecessary.*[LIMIT] is shown on the ICVC as temperature, pressure, voltage, etc., predefined or selected by the operator as an override or an alert. [VALUE] isthe actual pressure, temperature, voltage, etc., at which the control tripped.ICVC FAULTSTATEPRIMARYMESSAGESECONDARYMESSAGE PRIMARY CAUSE ADDITIONAL CAUSE/REMEDY100 PRESTARTALERTSTARTS LIMITEXCEEDED100Excessive compressor starts(8 in 12 hours).Depress the RESET softkey if additional startis required.
