  If your Guldmann Mobility Aid displays fault 16/20, which indicates a fault on the motor brake on the leader-leader PCB or motor, here’s what you can do: First, check the position of the handle. Then, check the cables and micro switch by pulling the emergency strap to see if the brake releases (you should hear a click). If it does, replace the PCB. If not, inspect the cable and connection (J12) or consider replacing the motor/gear.

  If your Guldmann Mobility Aid displays fault 18/1, indicating a communication fault with the twin hoist, you can try the following: Check the cables and connection between the PCB on the leader hoist (J10/J11 on 16) and the follower hoist (J10/J11 on 18). Verify the battery voltage on (18), ensuring it's at least 16 volts. Check the jumper settings on (18). If problems persist, replace the PCB on either (16) or (18).

  If your Guldmann Mobility Aid displays fault 17/1, which indicates a communication fault with the Follower PCB (17), here’s how to troubleshoot: Check the cables and connection between the leader and follower PCB (J10 on 16 to J10 on 17). Check that the LED is on (17). If the LED is on, check the jumper settings and consider replacing PCB (16) or (17). If the LED is off, check the battery voltage, ensuring it is a minimum of 16 volts, and verify the battery connection on (17). If these steps don't resolve the issue, replace (17).
