Example of a Remote Panel"Remote Prelube"
The "remote prelube" switch is a two-position switch that is customer supplied. The switch connects to the digital input "PLC Card 4 Input 4".Note: The Engine Control Switch must be in the "Remote Position" position in order to be functional. The PLC must be running in order for the switch to be functional.When the switch is in the "Prelube On" position, the "PLC Card 4 Input 4" will be active. This activates the digital output "PLC Card 5 Output 1". The IPR (Intermitent Prelube Relay) is activated. The IPR activates the Intermittent Prelube Solenoid Valve. This starts the prelube pump. The prelube pump will run for 15 minutes or until the engine starts."Remote Prelube Indicators"
The contacts of the IPR are normally open. The contacts are customer supplied. The terminals 153A and 153C may be wired to an indicator lamp. The lamp shows that the prelube pump is running. The lamp is customer supplied.The contacts of the SOSRX (Starting Oil Sensor Relay) are normally open. The contacts are customer supplied. The terminals 211A and 211C may be wired to an indicator lamp. The lamp shows that the engine is prelubed. The lamp is customer supplied.Note: The contacts are dry contacts. The contacts must be wired in series with the indicator lamp and a power supply that is appropriate."Remote Start"
The "remote start" switch is a two-position switch. The switch is customer supplied. The switch is a momentary switch. The switch connects to the "PLC Card 4 Input 5".When the switch is held in the "Start" position, the "PLC Card 4 Input 5" is active. The digital output on the "PLC Card 5 Output 3" will be turned on if one of the following conditions is present:"Remote Tachometer"
A 4-20 mA gauge that is customer supplied can be connected to "PLC Flex Module 4 Outputs 1-4". Any of the 4 inputs can be used. The output must be properly configured by using the "Programable Output Configuration" screen."Remote Stop"
The "remote stop" switch is a customer supplied switch. The switch is a push button switch that connects to the "PLC Card 4 Input 6".Note: The Engine Control Switch must be in the "Remote Position" in order to be functional. The PLC must be running in order for the switch to be functional.When the push button is pushed, the "PLC Card 4 Input 6" is active. Then, the digital output "PLC Card 5 Output 0" becomes active. The FCR (Fuel Control Relay) becomes active. The FSOS (Fuel Shut Off Solenoid) is energized. If the panel is configured for Energized to Run, the Fuel Shut Off Solenoid is not energized. The engine will shut down in both cases."Remote Emergency Stop"
The "remote emergency stop" is a customer supplied switch. The switch is a push button switch with a mushroom head. Two normally open contacts are required on the switch. One set of contacts is wired between terminals 1 and 84 in the control panel. The other set of contacts is wired
