TROUBLESHOOTING
TESTING AND TROUBLESHOOTING GUIDE
Pan Status Keyboard Test:
Press a pan button once. The corresponding light
turns green. Press the same button again. The
corresponding light turns red. Repeat for every button
on all keyboards.
Troubleshooting:
1. If the light turns red, and then turns off, the HOLD
time is equal to 0. Program a new duration for at
least one of the PHASEs for that pan.
2. If the Keyboard test fails, plug the keyboard into
a different Warmer jack on the Station Unit and
repeat the test on that keyboard. If the keyboard
continues to fail the test, the keyboard is suspect.
If the keyboard passes the test when plugged
into a different Warmer jack, the Station Unit is
suspect.
Station Interface Unit Power:
1. Power up the Warmer unit.
2. Observe that the keyboard lights illuminate yellow,
then red or go out depending on the programmed
hold times.
Troubleshooting:
Check that the Warmer control powers up and the
Warmer heats up. If not, call Duke Mfg. for Warmer
service at 314-231-1130 or 800-735-3853.
Service Hot-Line:
If you believe that you have a Product Quality Timer
System service issue, perform the steps outlined above.
If a test fails, perform the troubleshooting steps to see if
this resolves the problem. Continue the remainder of the
testing, if possible, to uncover any additional problems
and document the symptoms and results. Please have
this data handy before calling the Duke troubleshooting
Hot Line listed above. For optimum support, please
be near the suspect units with a cordless phone, if
available, when calling our Technicians.
IMPORTANT: Standard control location is at the right
hand side on models IRHU-12 and IRHU-23. The IRHU-
22 was designed to have the control location at the left
hand side making the connection of the keyboard into
the control board in reverse, i.e. Front keyboard plugs
into the “BACK” at control board and back keyboard
plugs into the “FRONT” at the control board.
