3.11 WARNINGS (CONTINUED)

COMMUNICATION FAIL 1 (or 2 - 4) - This warning will occur if the compressor is the lead unit while using integral sequencing and is unable to communicate with another compressor.

SERVICED REQUIRED - The Intellisys has 2 levels of service. The service level can be set at the factory or by an Ingersoll-Rand service representative. Either service level will issue a “SERVICE REQUIRED” warning at 150 hours. This warning is a reminder for initial service and can be cleared by the operator.

Level 1 - If service level 1 (default) is selected, a “SERVICE REQUIRED” warning will be issued every 2000 operating hours. This warning is to serve as a reminder to have the unit serviced and can be cleared by the operator.

Level 2 - If service level 2 is selected, service warnings will be issued every 2000 operating hours (default) or in 3, 6, 9, or 12 month intervals, as selected at the factory or by an I-R service

representative. Service warnings at level 2 are issued in 3 stages. First a “100 HOURS TO SERVICE” or 14 DAYS TO SERVICE” (depending on the service interval type) warning will be issued. This warning will let the operator know that the time for service is approaching and can be cleared by the operator. Following that, 100 hours or 14 days later a “SERVICE REQUIRED” warning will be issued. This warning can be temporarily cleared by the operator, however it will return 24 hours later if service has not been performed by an I-R service representative. A new service period will start when service is performed. If another 100 hours or 14 days elapses and service has not been performed, an “ALARM-SERVICE REQUIRED” warning will be issued. This warning can only be cleared by an I-R service representative.

SENSOR FAILURE 6APT - This warning will occur if the separator delta-p sensor option is installed and sensor 6APT is recognized as missing or broken.
