7. Troubleshooting
Condition Check
Initial Check Whenever power is applied to the SEQ the LCD display should be illuminated and should
show two lines of text as follows:
Status: All On or All Off 120VAC (or whatever the actual line voltage is)
Protection: Good
If the first line of the display does not show “Status” the unit is in programming mode and
therefore the three banks of receptacles will not turn on. Turn the SEL rotary encoder
counter-clockwise and then press the button to get out of programming mode.
If the display is not illuminated and showing the above two lines of information check that
power is actually being supplied to the unit and that the breaker on the rear panel adjacent
to the power cord has not tripped. If you are certain that power is being supplied to the
unit, consult the factory for assistance.
Unit will not power up from
remote control connection
If you have performed initial checks as above and the unit will still not power up it could be
because the “down” input (terminal 2) is being held active all the time. Remove the
terminal block from the rear and check that the Up and Down signals are correct with a
meter.
The front panel button will
not work
Check whether the front panel button has been programmed to Delay or Disable. If it has
been programmed to Delay you must hold the button for one second before it will operate.
If it has been programmed to Disable it will not operate at all.
The front panel button will not work if the Up & Down Inputs has been set to Latching or 5-
30V DC. This is due to the fact that a latching type input will always over-ride a momentary
switch like the front panel button.
The unit sequences up but
will not sequence down
Check the remote control connections using a meter and also the programming of the Up
& Down Inputs. If Up & Down Inputs is set to Separate Up & Down and you are using a
single momentary switch the unit will sequence up but not sequence down.
The unit starts to
sequence up but then
immediately sequences
down
There are two likely causes for this: One cause is a Down input that is on all the time and
over-riding the power up sequence. Check the down input with a meter. The other cause is
that the Over-Ride Func menu item has been set to Master when the unit is not actually
connected to another SEQ and is in cascade mode. Change this menu item to Disable.
The unit will not go into
programming mode
You must power down the unit first before you can get into the programming mode.
8. Error Codes
Error Error Description
Error 05 The calibration of the AC voltmeter is no longer accurate. The unit is otherwise fully operational.
Call the factory for assistance.
Error 15 There is a checksum error in the non-volatile memory. This indicates that the set-up information
could be incorrect. It is recommended that you completely check the programming and save the
settings again. If Error 15 is still displayed there is most likely a permanent problem with the non-
volatile memory.
Error 16 There is an internal error. The unit will need to be returned to the factory for repair.
Error 24 Please call the factory.
