Lafayette 3606 Engine BDMPC00 - Caterpillar

The Implement Lockout Relay is a means to override the Cab Implement Lockout Switch and Still allow the Implement ECM to control the Implement Lockout Solenoid. The Implement Lockout relay becomes Energized (from the RCM) when the RCM is powered to prevent Implement Lockout inside the cab from becoming functional. Now, circuit from the Implement ECM is diverted from the switch directly to the solenoid.Installation of the RC Kit doe extend the Implement Lockout Circuit to the relays on the cab. This means that 2 wires are labeled the same in 1 RC harness. It is unlikely but the swapping of the wires at pin locations (M927) could prevent machine activity. Implement Lockout Relay deenergized state supplies power back to the Implement Lockout Switch as normal operation.

"Auxiliary Power" relay mini schematic
The Auxiliary Power Relay is a means to provide power to the Ethernet Devices and Mode Select Indicators. When the RCM is Powered, the RCM energizes the coil of the Auxiliary Power Relay to send Auxiliary Power to the Ethernet Router, Switch, WiFi Radio, Cameras, and Mode Select Indicators. When the RCM is not powered, The Auxiliary Power Relay may also be energized from the Cab Keyswitch through a diode to allow the Ethernet devices to be powered while the machine is in Manual Operation.

"Machine Horn" relay mini schematic
The Machine Horn Relay is a means to allow the operator console to activate the machine horn. Activating the Horn Button on the Console will enable the RCM to energize the coil on the Machine Horn Relay. Energizing the coil will contact the switch power from the horn fuse to the horn, to a similar circuit as the cab. Installation of
