Connection Diagram for PumpProxy DC Control Module for Engines with a 117 Murphy Switch
Installation: Mount the 4G LTE Modem outside and the PumpProxy DC Control Module inside the engine panel or a weatherproof enclosure. Connect the ribbon cables with the Mating Connector. Wire the PumpProxy controller as show in the diagram. The wire labeled “+ Positive” with red heat shrink over a black wire and the orange pilot wire should be connected to the terminal on the Murphy switch labeled C with sta-kons. The wire labeled “– Negative” with black heat shrink over a white wire and one of the plain red wires should be connected to ground. The other plain red wire should be connected with a sta-kon. The two blue wires will not be use so should be capped off with a wire nut.
Operation: Start the engine manually. A green LED inside the PumpProxy Control Module will light when the engine is running to indicate that the control module has power and red LED will light to indicate voltage is detected on the pilot. A red LED will remain solid and a green LED will flash once per second on the 4G LTE Modem to indicate the modem is ready to receive phone commands. When a stop command is received by the modem, a yellow LED will light for 5 seconds, indicated that the Normally Open relay is activated and closed. This will apply Ground to the “S” terminal on the Murphy switch and stop the Engine.
