Cant set my compressor to automatic start/stop mode

I have a Ingersoll-Rand SSR-EP100 compressor. I need to set it as a back up. My manual does not give me a step by step way of doing it.

U NEED TO ADJUST THE PRESSURE SWITCH ON THE BACKUP TO A LOWER PSI. TO COME ON AFTER THE PRIMARY. EXAMPLE: PRESSURE SWITCH ON PRIMARY COMP. SET AT 140-175 PSI AND BACKUP SET AT 135-170 PSI. U CAN USUALLY TURN ONE CENTER SCREW IN THE PRESSURE SWITCH COUNTERCLOCKWISE TO LOWER THE PSI.

It depends if it is the old electro Pneumatic control or the more Current Intellisys control. The other recomendation pressure setting is incorrect! EP 100 is a 125 psi rated compressor. DO NOT EXCEED THIS PRESSURE!
IF you want a lead compressor setting Ideal would be cut in 110 psi and cut out would be 125. The "Lag" setting should be 100 psi and the cut out 120 psi. If it is the old Allen Bradley swith on the older style, the top screw is the high or cut out, the bottom is the differential or Cut in. If the compressor has an Intellisys controller, the go into Operator Set Points and set the desired pressure that way

Have a SSR-EP100 air compressor that shows


Try to reset the main motor and fan motor over loads by pushing the reset on the overload it self, Then reset the controller. If the error resets, before starting. put a clamp on amp meter on to L1 or L3 motor lead which is located in the compressor electrical box . Then start and observe amps when unit is making air fully loaded. Once you know how many amps at full load the unit is pulling ,look at the overload setting on main motor overload and see if it is approxmately 10 amps above the max amps being pulled.If not set it about 10 amps above your max load amps.

Cuts off with no reason


hi mate when the reach there working pressure e.g.150psi/10bar they shut off and then when the pressure drops to a pressure of e.g. 100 psi 7 bar they automatically start back up and pump back upto they working temperature or if it dont start at all it could either be a faulty pressure switch or a fualty star delta starter if its 3 phase 415 volts if its 240volt there are only a pressure switch which will be faulty get a sparky in to sort it out there buggers to mess with 415volts 240 volts easy

Cant set my compressor to automatic start/stop mode


Sorry, what do you mean it 'blows off',, the relief valve is letting off pressure ? Sounds like you need to replace it with the proper psi Relief valve or just a new one. Then you say it restarts but in your question you say 'Cant set my compressor to automatic start/stop mode' If it is restarting that means it is automatically 'stopping' then automatically 'starting' Please clarify your question.
