Oil Failure Switch:

 

12A2117A05 (Copeland Sentronic)  On compressors manufactured before March 2011. 

This device monitors the compressor oil pump differential pressure. If oil pressure drops below 7-9 psig for a 
period of two minutes, the Sentronic module will open the control circuit contact and shut the machine off.    
Factory set @ 7-9 psig (Manual reset) 
 

CoreSense:

  Replaces Copeland Sentronic Oil Pressure Safety module on all Discus compressor and the 

Electronic Motor Protector module in 4D & 6D compressors.  Note: 2D & 3D compressor will still have 
Internal Line Break overload protection.   
 
The oil pressure monitoring portion of the CoreSense will act very similar to the Sentronic Oil Pressure 
Safety switch.  A current transformer (CT) in the compressor junction box determines when the compressor 
is running and starts monitoring oil pressure.   
 
The CoreSense module has power applied at all times to allow for more detailed fault notification.  An LED 
will flash when a fault occurs.  The number of flashes will identify the fault condition.
