4.4 GRADIENT TEST
CAUTION (HP, IN)
Before carrying out this test, ensure another person is present to prevent the powerchair from tipping backwards.
Drive the powerchair forwards up its maximum rated gradient. While on the gradient release the SID and ensure the
powerchair comes to rest and the brakes are applied without the front wheels lifting off the ground.
Operate the SID forwards and continue driving up the slope. Ensure the pick-up is smooth and positive.
Stop the powerchair and reverse down the gradient. While on the gradient release the SID and ensure the powerchair comes
to rest and the brakes are applied without the front wheels lifting off the ground.
4.5 LIGHTS, INDICATORS AND HAZARD LAMPS TEST
If lights are fitted:
Visually check each bulb for correct illumination.
Check each bulb for correct illumination and that the flash-rate is 1.5Hz ± 0.5Hz.
Disconnect each bulb in turn and check that the remaining bulb for that side flashes at 3Hz ± 0.5Hz.
If hazard lamps are fitted:
Check each bulb for correct illumination and that the flash-rate is 1.5Hz ± 0.5Hz.
4.6 ACTUATOR TEST
If actuators are fitted:
Check each motor for correct direction of movement.
Ensure the mechanical end-stops are secure and that they stall the actuator motors, thus operating the ISM’s
automatic end-stop detection.
4.7 INHIBIT INPUT TEST
Insert an appropriate battery charger, or equivalent inhibit connection, into the Charging Connector on the Omni2 Input
Section and ensure that drive is inhibited.
If Inhibits 2, 3, 4 and 5 are used for inhibit or speed limiting purposes, suitable tests should be devised to ensure correct
operation.
