The lift does not move in both directions

The LED remains dim upon joystick operation

Connect the short-circuit connectors K6 and K9
A. The lift moves after operation of the direction switch (DS)
The fault is located in the chair
•
One of the armrests is not folded down
•
The armrest switch AS1 or AS2 is faulty
•
The active seat switches are faulty
•
Earth short at K6-4
•
Wire break between K6-4 and the joystick
B. The lift does not move after operation of the direction switch (DS)
The fault is located in the unit
The lift does not operate in the traction mode
•
The data card is not inserted correctly
•
Wire break between K4-12 and K6-4
•
Wire break between K1-3 and K1-4
•

Grease on brakes levelling motor
Levelling motors with production date 15 Dec 2022 to 7 Jul 2023
Clean levelling motor with brake cleaner according to work instruction
AA30566 or replace unit
Encoder count issue / wrong encoder code in software
T-print, 4.1, 4.2, 4.3, 4.3 Updated, Q-print
Replace the PCB with 4.3 Updated V2. The new software is backwards
compatible so when replacing a PCB in the field (Q / 4.1 / 4.2 / 4.3 / 4.3
Updated) with the new version the tilt that is in the lift does NOT have to be
changed. The PCB T4.3 Updated V2 works with both tilt switches.
