LEDs on DMR-30 illuminated:
BT7-04 (cage rotate left output), BT5-06 (throttle out-
put), BT6-12 (low flow valve output).
Cage Trim Up
Function enabled - foot switch depressed.
LEDs on DMT-30 illuminated:
BT4-03 (foot pedal), BT4-11 (cage trim up).
LEDs on DMR-30 illuminated:
BT6-05 (cage trim up output), BT5-06 (throttle out-
put), BT6-12 (low flow valve output).
Cage Trim Down
Function enabled - foot switch depressed.
LEDs on DMT-30 illuminated:
BT4-03 (foot pedal), BT4-06 (cage trim down).
LEDs on DMR-30 illuminated:
BT6-06 (cage trim down valve), BT5-06 (throttle out-
put), BT6-12 (low flow valve output).
Auxiliary Power (Emergency Functions)
DMT-30 BT3-08 (auxiliary power)
DMR-30 BT5-10 (auxiliary output)
NOTE: If the auxiliary switch is depressed when
the engine is running, the engine will stop
immediately.
Drive Functions
Drive functions are relayed to the drive pump from
the joystick control. All adjustments are made at the
joystick controller. Brake release and throttle com-
mands are relayed from the joystick controller to the
DMT-30 on BT3-08 (JSA) Joystick actuator.
Drive Forward
Function enabled - footswitch depressed.
BT3-02 on DMT-30 (jsa) joystick actuator, BT5-06 on
DMR-30 (throttle output), BT5-04 (brake release).
Drive Reverse
Function enabled - footswitch depressed.
BT3-02 on DMT-30 (jsa) joystick actuator, BT5-06 on
DMR-30 (throttle output), BT5-04 (brake release).
Steer Right
Function enabled - foot switch depressed.
BT4-05 on DMT-30 (steer right), BT5-06 on DMR-30
(throttle output), BT6-10 on DMR-30 (high flow
valve), BT7-02 on DMR-30 (steer right output).
Steer Left
Function enabled - foot switch depressed.
BT4-10 on DMT-30 (steer left) BT5-06 on DMR-30
(throttle output) BT6-10(high flow valve) BT7-01 on
DMR-30 (steer left output)
High Torque Position
No signal on DMT-30 or DMR-30.
High Speed Position
BT3-10 on DMT-30 (high speed) is illuminated, BT5-
07 on DMR-30 (shift) is illuminated.
Braking
Brakes are normally locked when the machine is not
in use. Brakes are unlocked by a charge pressure
(380 PSI) from the drive pump. A 12 volt signal is
sent to the brake solenoid by BT5-04 on DMR-30.
Tilt
A 12 volt signal is at BT1-05 (tilt signal input) when
the machine is level. If the machine is out of level or
the level sensor fails, the machine will stop. Red wire
on level sensor is power in, and white wire is signal
out.
Interlocks
There are two interlocks on the machine.
1. Lift Interlock: A12 Volt signal is sent to BT2-01 on
DMR-30; allows high speed travel.
2. Telescope interlock (at tail end of boom): A 12
volt signal is sent to BT1-11 & BT1-12 on DMR-
30 when boom is fully retracted; allows high
speed travel.
