UPERFLEX

ONTROLLER

There are Three compnoents to the SuperFlex sys-
tem. Processor (SuperFlex), transmitter (DMT-30)
and receiver (DMR-30).
The SuperFlex processor has Three 12 pin connec-
tors. The SuperFlex connections are designated as
sfBT1 thru sfBT5. There are Two auxiliary (AUX) high
current outputs on sfBT3. These outputs control drive
and lift/extend/swing operations.
The transmitter receives input signals from the joy-
sticks located on the upper control box. The transmit-
ter and receiver have LED indicators which can be
used as diagnostic tools. These LED’s are BT1-BT4
for the inputs and BT5-BT7 for the outputs.
There are two LED’s in the proportional joystick.
They indicate direction of rotation of the joystick
digisensor.
“A” LED indicates counterclockwise rotation and “B”
LED indicates clockwise rotation.
The dual range (switched) inputs may be indepen-
dantly adjusted by using the “Optimizer” for calibra-
tion.
OPTIMIZER ADJUSTMENTS
Threshold - The amount of adjustment that causes
the machine to just start moving.
Max Out - Maximum output when joystick is com-
pletely deflected.
Low Range - Low range signal
Ramp Up - Sets acceleration time.
Ramp Down - Sets Deceleration time.
There are Three LED’s on the SuperFlex processor.

CPU LED (Middle LEAD) Flashes on and off if the
system is operating properly. This LED will be off if
there is no power to the CPU. If the LED is on contin-
uously, there is a CPU failure and the SuperFlex con-
troller must be replaced.
INPUT LED Flashes if one or more of the joysticks os
being operated. LED is off if all joysticks are in their
neutral position.
If LED is off when any joystick is being operated,
check the wiring and check for 12 volt power to the
joystick. If LED is on continuously, one of the digisen-
sor wires is shorted to 12 volts.
OUTPUT LED flashes when any of the PMW outputs
are active. If LED is on continuously, one of the PMW
outputs is shorted to ground.

Lower Control Box

Electrical Power Up

Both Emergency Stop Switches are pulled out.
Lower control box key switch in chassis position.
BT2-02 on DMR-30 (chassis power) will be illumi-
nated.
Other LED’s on DMR-30 which may be illumi-
nated:BT2-07 (tilt), BT2-12 (telescoperinterlock),
BT4-02 (lift interlock #1), BT4-03 (lift interlock #2),
BT4-04 (axle pressure, AEP), BT7-04 (ignition)
The CPU LED on the DMR-30 and theSuperFlex
should be flashing on/off. The buss LED on the DMR-
30 should be flashing on/off. Relay #2 and #3 acti-
vated.

Engine Start

BT7-04 on DMR-30 (ignition) illuminated.
Operate start switch
BT7-08 (hour meter) illuminated, the hour meter
should flash, BT2-03 (start input) will illuminate, BT2-
11 will illuminate while engine is running.

NOTE: If no oil pressure is detected ignition sig-

nal is deactivated. Engine will not continue to
run.

Glow Plug

BT6-08 on DMR-30 illuminated.

Boom

Boom Up

Function enabled
LED’s on DMR-30 illuminated:
BT2-02 (chassis select), BT2-05, BT1-07 (lift input),
BT5-09 (lift output to valve), BT6-06 (dump valve out-
put), BT7-09 (mid throttle output), sfBT3-5 on Super-
Flex (lift up output)

Boom/Axle Logic Interlock

If axles are not fully extended, boom will not elevate
beyond 42 degrees. When axles are fully extend
there is a 12 volt signal to relays #5 and #6. If both
relays are latched there will be a 12 volt signal sent to
BT4-04on the DMR-30 and sfBT2-10 on the Super-
Flex. There will be 12 volts at TB7 and the green light
(axle extend) on the upper controller will be illumi-
nated.
