Activation/input wires:
• Input 1
• Green input wire
• “Ground activation”
• On/off type activation wire (digital input)
• This wire activates the torque reduction whenever a ground is applied to it
• Unless “Kill Time” is in position “F” this input does not impact the duration of the torque reduction
event, just when it starts to occur
• Can be activated via a momentary switch
• Releasing the digital input does not end the torque reduction event.
• Input 2
• Yellow input wire
• “+12 volt Activation”
• On/off type activation wire (digital input)
• This wire activates the torque reduction whenever +12 volts are applied to it.
• Unless “Kill Time” is in position “F” this input does not impact the duration of the torque reduction
event, just when it starts to occur
• Can be activated via a momentary switch
• Releasing the digital input does not end the torque reduction event.
• Input 3
• Purple input wire
• “0-5 Volt Analog Input”
• 0 to 5 volt variable input (analog input)
• This input allows an external device to control the amount of timing retard (torque reduction).
• 0-5 volts = 0-50 degrees of timing retard
• 0.1 volts per degree, minimum 5 degrees=0.5 volts
• Minimum retard of 5 degrees
• Considered active above 0.5 volts
• Anything below 0.5 volts is ignored (no retard)
• Timing retard is active for as long as Analog Input is active (above 0.5 volts)
• Ramp in and ramp out rate of timing retard still controlled by “Retard Slope” setting
• Maximum amount of timing retard still limited by “Max Retard” setting
• “Kill Time” and “Kill Time Adder” settings do not apply to this input
• Input 3 over-rides digital inputs 1 & 2
• The LNC-TRM scans the analog input voltage first. If a valid voltage is present, it ignores the
digital inputs.
