  If the Ingersoll-Rand Controller's ALARM light is on, first check the status of each compressor using the COMPRESSOR STATUS button to identify any compressor showing “#n COMM FAILURE” or “#n ALARM”. If a compressor shows “#n COMM FAILURE”, refer to the communication problem troubleshooting steps. If it shows “#n ALARM”, go to that compressor and resolve its alarm. Also, refer to the “SENSOR FAILURE” troubleshooting steps.

  To troubleshoot bad system air pressure readings on your Ingersoll-Rand Controller, especially if you're getting a zero pressure reading when pressure is present: * Check for a defective ISC air system pressure transducer, bad connections, or broken wires. * Verify that the air system pressure transducer isolation valves allow system air to reach the transducer. * Ensure the transducer isolation valves are venting the transducer to the atmosphere.
