Service manual

Maximum Offset Error:

There are limits on how far any post can be out of level from any other post, even when using Single and Pair

overrides. If any post reaches its limits, one of the following screens will be displayed (depending on if the

unit is being used in All, Pair, or Single). The highest and lowest posts will be identified. Raising is only

allowed on the lowest post, Lowering only allowed on the Highest post. These offsets are normally outside

the bounds of normal usage and prevent extreme out of level conditions.

Lock Not Releasing Error:

This screen will only occur during Lowering of the lift. This screen

indicates that one of the locks is not released, and it will prevent the

lift from lowering. This may be due to a lock on the identified post

from being mechanically parked, the solenoid not pulling the lock

back, or the sensor not “seeing” the lock pulled back (sensor may

need to be adjusted). The post that causes this error will be

identified.

i.e. The display to the left shows that post 1 lock is not released.

Loss of Motion Error:

This screen will occur if any post is not sensing motion when a

raise or lowering command is present. This may occur if a post

string-pot is disconnected, malfunctioning, or cable is broken. This

also may occur if the lift is lowering onto an obstruction to prevent

its motion. Press Exit key at post this occurs at to remove message.

(Note: If message remains, then the string-pot is disconnected and

needs to be repaired)

i.e. The display to the left shows that post 4 experienced a loss of

motion while raising or lowering.
