Troubleshooting

The Superflex 4 System has been designed to perform in the harsh environments of the mobile equipment

industry. Most of the common problems encountered are external to the Superflex 4 Controller. Problems

may include: broken wires, loose or corroded or defective connections, wiring errors, wiring shorts, and

improper power supply voltages. The Superflex 4 Controller has several built in features that can assist

with testing and troubleshooting your system.

Check for the following machine related problems -

Power is turned on and supplied to the Superflex. Supply voltage is OK (batteries aren’t weak).

Make sure all cables and wiring are connected properly.

Be sure the ground wiring is good.

Are there any machine interlocks (or “enable” signals) that are preventing operation?

LED’s on Superflex

Figure 16 shows the location of three red indicator LEDS. These indicators provide the following

information.

The middle or CPU LED flashes if system is OK. This LED is off if there is no power being supplied to

the Superflex. If this LED is on constantly (not flashing) there is a CPU failure, and the Superflex 4

Controller must be replaced or repaired by OEM Controls, Inc.

The INPUT LED flashes whenever one or more joysticks (Digisensors) are operated. This LED is off if

all microswitches (Digisensors) are off. If this LED remains off when a joystick is operated, check the

wiring, and make sure there is power to the joystick. This LED will be on continuously (not flashing) if one

of the Digisensor wires is shorted to +12 volts.
