Right Console (1) Drum offset switch (2) Propel leverDrum offset switch (1) is located on propel lever (2), on the right console. This switch is a three position, momentary switch. The center position of drum offset switch (1) is the HOLD position, the right position is the OFFSET RIGHT position, and the left position is the OFFSET LEFT position. The switch is spring returned to the HOLD position. Drum offset switch (1) is normally open. This switch provides input signals to the ECM. The ECM monitors the signal from the drum offset switch and the drum offset proximity switch to control the drum offset solenoids. When the drum offset switch is moved out of the HOLD position, the ECM directs an output signal to the appropriate drum offset solenoid, and the offset cylinder extends or retracts. The ECM continues the output signal until the operator releases the drum offset switch or the proximity switch reaches the center position. Note: When the proximity switch reaches the center position, the ECM discontinues the output signal to the drum offset solenoid.
