CONTROL
The CELLmatic 1502 control panel is equipped with a microprocessor. The microprocessor monitors and
adjusts the operation of the compressor, and facilitates communication between operator and the machine.
MONITORING
The microprocessor monitors and reacts to error conditions in the compressor. The following conditions are
monitored:
- Suction temperature
- Suction pressure
- Discharge pressure
- Oil differential pressure
- Pressure drop over oil filter
- Oil temperatures
- Oil level in oil separator
- Pressure pipe temperature
If the threshold limit value of the set point is exceeded, possibly with a delay for the individual operating
parameter, a message will be sent either through an alarm or a cutout (the compressor will stop).
ALARM
An alarm message means that a preset limiting value has been exceeded, and something might go wrong
shortly. I.e. a warning.
In the event of an alarm the message "P1 ALARM" will appear in the upper left-hand corner followed by the
operating parameter causing the alarm.
The alarm and the time of alarm will be stored in the memory of the control, and can be read out if the
computer is connected to a main control unit.
An alarm is reset by pushing the <CLA> (= Clear Alarm; F6), but it will appear again immediately, if the error
causing the alarm is not removed from the system.
CUTOUT
Cutout means that an operating situation has risen, which require the compressor to be stopped. Cutout
conditions are shown in the same way as alarms, and are to be reset at the <CLA> before the compressor can
be restarted. If a picture with the operating parameter concerned is not already shown in the display, there will
automatically be scrolled to a display picture showing the operating parameter together with a "frozen" cutout
value.
EMERGENCY STOP
In the event of an emergency stop the compressor and the oil pump will stop immediately, but it will not
prevent the next slave from starting.
After deactivation of the emergency stop, <CLA> must be keyed before the compressor can be restarted.
