Control panel Elektronikon® Graphic
Regularly check the oil level. To do this, switch the Local/LAN switch to Local and press the stop button (9).
Three minutes after stopping, sight-glass (Gl) should be between 1/4 and 3/4 full.
Unless the Slave unit (in this case the GA MED compressor) is put in Isolated mode on
the ES-MED (see dryer instruction book), a plant fault will be transmitted.
After checking the oil level, put the Slave again in
Integrated mode .
If the oil level is too low, press also the emergency stop button (10), close the air outlet valve and open (if
provided) the manual condensate drains. See section
Introduction and section Condensate system for location
of the outlet valve and the water drain. Next, depressurise the oil system by unscrewing oil filler plug (FC)
one turn and wait a few minutes. Remove the plug and top up oil, until the sight-glass (Gl) is full. Fit and
tighten the plug (FC).
