Symptom Procedure
Desk is powered, but
will not initialize.
1. Try pressing and releasing the “down” button a few times before
pressing and holding for five seconds.
2. Take note if the control box has a special configuration. If the desk
is programmed with a lower stroke limit, to avoid collision with
something like a filing cabinet, it is possible that it has a custom,
longer Forced Initialization Time. This is the time required to hold
the down button before initialization begins. Sometimes this is ten
seconds or longer.
3. If you have a standard control box without a special configuration
(i.e. “Plug & Play”), try to initialize each leg in Channel 1 by itself,
with nothing else plugged into the motor channels on the control
box. Swap the motor cables so that a different motor cable is used
to initialize Channel 1 by itself. The problem could be a faulty desk
leg or a faulty motor cable.
Channel-specific error
(Ex: E41 – Channel 1
overload) – Everything
except Piezo errors
(E59-E63).
1. Swap the motor cable connections at the control box (Motor cable
#1 from channel 1 to 2, motor cable #2 from channel 2 to 1).
If error code remains E41 on the digital display, there could be a
problem with the application (load or obstruction on one side) or a
bad control box. If the error changes to E42, reference
Procedure 4, symptom “Desk is powered, but will not initialize”.
2. Swap the motor cable connections at the desk legs, so that the leg
that was originally connected to Channel 1 is back in Channel 1, but
with the motor cable that was originally connected to Channel 2. If
the error code remains E42, it is most likely a bad motor cable, now
connected to Channel 2. If the error code goes back to E41, it is
most likely a bad desk leg, now connected to Channel 1.
Desk is uneven. 1. Initialize the control box. If both legs begin to run down, complete
the initialization. If only one leg moves, stop and move to step 2.
2. Check motor cable connections. Check to ensure motor cables are
able to move freely and do not become stretched or pinched during
movement. With a standard control box (i.e. “Plug & Play”), it’s
possible that only one leg is connected, and connected to
Channel 1. In this case, it will initialize and run Channel 1 only. If
there is only one leg but it’s connected to Channel 2, it will not
initialize.
3. If a motor cable was disconnected, try initializing again.
4. If unsuccessful, connect the desk leg from Channel 2 into Channel 1,
with nothing in Channel 2, and initialize.
5. Try initializing the same leg that’s in Channel 1, but with a different
motor cable. If it still won’t initialize, replace the desk leg.
