3.32 SWITCH SHORT
This occurs when the CJSM2 has detected that either of the External Switch Jack Sockets has a s hort-circuit.
The actual Switch that has the short-curcuit is indicated by the Trip Code. The code is in Hex.
1E0D - External On/Off Switch jack socket.
1E0C - External Profile/Mode Switch jack socket
Check the operation of the switch and all cables and connectors between the CJSM2 and the identified switch.
If the trip is still present after the above checks have been made, then the switch or the CJSM2 may be defective. Refer to
Section 5.
4 BASIC TESTS
After a repair has been completed, the following tests should be carried out. These are minimum recommendations, depending
on the nature of the original trip then additional tests may be required.
WARNING:
These tests are a minimum recommendation only. It is the responsibility of the service person(s) to perform other tests
relevant to the original trip and wheelchair type. Refer to the wheelchair’s Technical Manual for exact information of other
tests. Curtiss-Wright accepts no liability for losses of any kind arising from the carrying out of the described tests, or from not
carrying out additional relevant tests.
These tests should be conducted in an open space and a restraining device such as a seat belt should always be used. Curtiss-
Wright accepts no liability for losses of any kind arising from failure to comply with this condition.
4.1 GENERAL INSPECTION
Make sure all connectors are securely mated.
Check the condition of all cables and connectors for damage.
Check the rubber gaiter or boot around the base of the joystick shaft for damage. Check visually only, do not handle
the gaiter.
Make sure that all components of the control system are securely mounted.
Do not overtighten any securing screws.
4.2 BRAKE TEST
These tests should be carried out on a level floor with at least one meter clear space around the wheelchair.
Switch on the control system.
Check the screen remains on after initialization.
Push the joystick slowly forwards until you hear the parking brakes operate. The wheelchair may start to move.
Immediately release the joystick. You must be able to hear each parking brake operate within 2 seconds.
Repeat the test a further three times, pushing the joystick slowly backwards, left and right.
