CAUTION! Improper alignment of connector plug can cause system failure. USEEXTREME CARE when making connection. Unit MUST BE DISCONNECTEDFROM POWER SOURCE before connecting.
How to test voltages when checking electronics
Measuring voltages present at wall plate controlwill aid in determining damaged circuitry inelectronics housing.Set voltage meter to DC and touch black meter lead (-)on meter to #9 screw terminal on wall plate connector.(Black wire - ground)Touch red meter lead (+) to each of the colored wireslisted below.
Symptom: Unit may not park.1. White wire voltage range 4.8 VDC - 5 VDC.
(4.7 would indicate damaged circuitry in theelectronics housing — replacement of electronicshousing needed.)
Symptom: Unit may fail to rotate or elevate.2. Purple wire voltage range 4.8 VDC - 5 VDC.
(4.7 would indicate damaged circuitry in theelectronics housing — replacement of electronicshousing needed.)
3 - 6. Blue, green, yellow, orange. These wiresshould measure .5 VDC or 1.8 VDC, depending onLED states.
7. Red wire will read supply voltage to the unit whenwall plate is switched on.
8. Brown wire will read primary voltage supplied tounit (11 to 13.8 VDC)
9. Black wire is ground.
