Shut Down And Restart - Beko DRYPOINT RA 20-960 Instructions For Installation And Operation Manual

Note!
A dew point between 0°C and +10°C displayed on the DMC 18 control unit is considered to be correct
according to the possible operating conditions (flow rate, air inlet temperature, ambient temperature etc.).
During the operation, the refrigerating compressor runs continuously. The dryer needs to be switched on during the
entire compressed-air usage time, even if the compressed-air compressor works periodically.

Shut down and restart

RA 330-960 3phase - during short-term inactivity (max. two to three days), it is advisable to leave the
dryer and the control panel connected to the supply current circuit. Otherwise, it would be necessary at a
restart of the dryer to wait two hours, until the crankcase heater of the compressor has heated up the oil
in the compressor.
Shut down (see Section 11.1 "Control panel")
• Ensure that the dew point temperature indicated on the DMC 18 electronic control unit is stable.
• Interrupt the compressed-air supply.
• After a few minutes, stop the dryer by switching off the main switch on the control panel (pos. 1).
Restart (see Section 11.1 "Control panel")
• Make sure that the condenser is clean (air-cooled).
• Ensure that the cooling-water flow and the temperature are in accordance with the provisions (water-cooled).
• Check whether or not voltage is applied at the dryer.
• Start the dryer by switching on the main switch on the control panel (pos. 1).
• Ensure that the DMC 18 electronic control unit is switched on.
• Wait a few minutes and then check, whether or not the dew point temperature indicated on the
DMC 18 electronic control unit is stable and whether or not the condensate is drained off at regular intervals.
• Establish the compressed-air supply.
RA 330-960 3phase - dryer remote control ON/OFF
• Remove the jumper between terminals 1 and 2 of the terminal strip and wire a potential-free contact (see electric
diagram).
• Switch ON the main switch - pos. 1 on the control panel.
• Close the contact at terminals 1 and 2 to switch on the dryer.
• Open the contact at terminals 1 and 2 to switch off the dryer.
Only use potential-free contacts that are suitable for low voltage. Ensure the sufficient insulation of
potentially dangerous voltage-carrying components.
Caution!
Automatic restart / remote control ON/OFF. The unit may start up without any active influence!
The user will be responsible for the installation of proper protections for possible sudden power
restoration to the dryer.
During the operation, the refrigerating compressor runs continuously. The dryer needs to be switched on during the
entire compressed-air usage time, even if the compressed-air compressor works periodically.
Note!
A dew point between 0°C and +10°C displayed on the DMC 18 control unit is considered to be correct
according to the possible operating conditions (flow rate, air inlet temperature, ambient temperature etc.).
Note!
The dryer must not be started up more than six times an hour. Wait at least five minutes prior to
every restart.
The user is responsible for the compliance with these provisions. Irreparable damage can be caused
when starting up the device too often.
