Resume / Accel; Clutch Released (Manual Transmissions); Service Brake Released (Automatic And Manual Transmissions); Installation - Detroit Diesel DDEC VI Application And Installation

Resume / Accel

The Resume/Accel switch is a momentary switch.
Resume: If Cruise Control has been disabled with the service brake or the clutch switch,
momentary contact to the ON position (switching the input to battery ground)
restores the previously set cruise speed.
Accel: When Cruise Control is active, the Resume/Accel input can be used to increase
power and speed by toggling the switch. Momentarily toggling and releasing the
Resume/Accel switch will increase the set point by 1.24 mph (2 km/hr) increments
for Cruise Control. Holding the Resume/Accel will increase the set point by 1.24
mph (2 km/hr) per second. When released the Cruise Control set point will be at
the current speed.

Clutch Released (Manual Transmissions)

This input indicates that the clutch is released and is used for suspending Cruise Control and
Auto Resume.
When the clutch is released, the input is at battery ground.
The digital input logic for the Clutch Switch disables Cruise Control in the unlikely event of a
broken clutch switch wire.
This switch is a normally closed switch.

Service Brake Released (Automatic and Manual Transmissions)

This input indicates that the brake is released when switched to battery ground. If the brake is
activated, then the input is not grounded and Cruise Control is suspended. Cruise Control is
resumed by using the Resume/Accel Switch.
The input logic for the Brake Switch disables Cruise Control in the unlikely event of a broken
brake switch wire.
This switch is a normally closed switch.
