5. ALARMS AND WARNINGS
Abnormal situations in the compressor are evaluated under 3 different categories as
ALARMS, WARNINGS and SERVICE REQUESTS.
Warnings are lowest level fault conditions and generate only visual warning, not affecting
the compressor operation.
Alarms are highest level fault conditions and cause the compressor to stop immediately,
the alarm relay to become active (if enabled by programming) and visual warning to occur.
If any fault condition occurs, the fault code will appear on the upper display and the related
fault category led turns on. (WARNING, ALARM or SERVICE)
Alarms and warnings may be reset by pressing the MENU button. The EMERGENCY
STOP alarm cannot be reset by pressing buttons, the alarm signal must be removed.
Service warnings may affect the compressor operation
depending on the amount exceeding the service period.
