Seal Leakage & Temperature Relays
Replacing a Crouzet PNR110A with a Macromatic SFP120A100 Seal Leak Relay
Wednesday: March 22, 2017Issue: I have been using a Crouzet PNR110A liquid level relay as a seal leak relay. To make it work properly, I had to jumper pins 5 & 6. Now, I want to switch to the Macromatic SFP120A100 unit and notice no such jumper is shown on the connection diagram. Is it required or not?
