Start-up 

iDRY iRDP CT 20-500 

 

27 

 
In the cycling operating mode (Energy Saving, ESS=YES – see section 8.12.7), the refigerating compressor is 
switched ON and OFF by the DMC51 electronic control unit, according to thermal load applied to the dryer. 
The dryer needs to be switched on during the entire compressed-air usage time, even if the compressed-air 
compressor works periodically. 
 

10.3  Shut down and restart 

 

iRDP CT 200-500 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 8.1 "Control panel")  

•  Ensure that the dew point temperature indicated on the DMC 51 electronic control unit is stable. 

•  Bypass the compressed-air supply. 

•  After a few minutes, stop the dryer by switching off the ON-OFF switch on the control panel (pos. 1). 

 

 

Restart (see Section 8.1 "Control panel"

)

 

•  Make sure that the condenser is clean. 

•  Start the dryer by switching on the ON-OFF switch on the control panel (pos. 1). 

•  Ensure that the DMC 51 electronic control unit is switched on. 

•   If the temperature displayed on the DMC51 electronic control unit is sufficiently high, verify that the refrigerating 

compressor starts within a few minutes.  

NOTE!

 – With low temperatures, the refrigerating compressor will remain 

OFF 

•  Wait a few minutes and then check whether or not the dew point temperature indicated on the DMC 51 electronic 

control unit is stable 

•  Establish the compressed-air supply. 

•  Check that the condensate is regularly drained 

 

iRDP CT 200-500 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 230 Vac. Ensure the sufficient insulation of 
potentially dangerous voltage-carrying components.  

 
In the cycling operating mode (Energy Saving, ESS=YES – see section 8.12.7), the refigerating compressor is 
switched ON and OFF by the DMC51 electronic control unit, according to thermal load applied to the dryer. 
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 32°F (0°C) and +50°F (+10°C)

 

displayed on the DMC 51 control unit is considered 

to be correct according to the possible operating conditions (flow rate, air inlet temperature, ambient 
temperature etc.).

 

 

Note! 

The number of starts/stops by pressing the ON-OFF switch - pos. 1 control panel should be limited to six 
per hour.  
Irreparable damage can be caused by starting up the device too often.
