Howard Miller HEKMAN 27978 Troubleshooting Manual

Customer Service Troubleshooting Guide:
- Mention: Advise the user not to function their base until the base has been initialized!
Each base must be initialized prior to use:
(Initialization sets the legs to be even and will move the base to its lowest position.)
o Note: Installer must assure that all cables are free to move adequately in order to
assure full up/down motion of the table without binding, tightness, or pulling.
Troubleshooting steps:
1. INITIALIZE
a. Start out by asking the user to initialize the table base. Wait while the user initializes the base.
i. To initialize the base:
b. Ask the user to cycle the table base 3 times to assure it is functioning well. The table may now be
used.
c. If the initialization successfully reset the base, confirm with the customer that base must be
reinitialized if power is disconnected. The handset should read the lowest height programmed at the
initialized state. Then complete the call.
2. ERROR CODES (If initializing the base does not work, please ask the caller which if any error
code is displayed on the handset)
a. Check all cords to assure they are fully connected and free of tangle.
o
E01: If error code E01, this indicates a leg error or column malfunction. Ask the user to disconnect and
reconnect the leg cables, assuring that the end connectors are fully seated and secured with the built-
in connector clip.
o
E03: If error code E03, this indicates the weight on the base is heavier than recommended. Ask the
caller to remove weight from the table. Verify that the table is level and appears normal. Reinitialize
the table per 1.a if needed. Then resume normal function.
o
E04: If error code E04, this indicates a data error. Ask the caller to perform the same functions as E01.
o
E05: If error code E05, this indicates a button is stuck. Ask the caller to check the function of the
buttons in the handset. If a button is stuck, press the button several times to loosen/reseat the button.
If the button does not become free, replace the handset. In the case, note the defective item and
supplier. In the narrative, note the troubleshooting efforts and the replacement part/s to be sent.
o
E06: If error code E06, this indicates an interruption of communication between the control box and
handset. You should ask the user to remove and reinstall the handset cable in the Control Unit,
assuring that the end connector is fully seated and secured with the built-in connector clip. If the
connector will not fully seat and clip into the Control Unit, determine if the handset connector is
damaged or if the Control Unit connector is damaged. Replace damaged item. If an extra handset is
available, replace the handset and check for function. If the table functions normally with the new
handset, replace the handset.

1. Check all cords to assure they are fully connected
2. Press and hold both the down and up buttons simultaneously until the legs start to
move. The legs will begin to move down at half-speed of normal operation.
3. Continue pressing the down and up buttons. The legs will move down to the lowest
position and will 'rebound' slightly. The rebound indicates that the base is initialized.
4. Release the down & up buttons. Initialization is complete.

If a cable doesn't fully seat or is damaged, determine if the cable connector is
damaged or the leg receptacle is damaged. Replace the damaged part and note the
issue in the case. In the case, note the defective item and supplier. In the narrative,
note the troubleshooting efforts and the replacement part/s to be sent.
