TROUBLESHOOTING
■
PROBLEM: Days are flashing, pressing any key does nothing
except
key turns output ON and OFF.
SOLUTION: Time of Day and Day of Week have not been set. See
"SETTING THE TIME"
NOTE: This is the condition after a reset. If the timer is found in this
condition after it has been installed, programmed and operating for a
while, it may indicate that electrical noise or voltage transients have
disrupted the microprocessor causing a loss of program information.
Call 1-800-391-4555 and request that a no-charge "Snubber Filter" be
sent to you to place across the input to the timer, which may solve the
problem.
A second, but very unlikely cause of loss of program is a power fail-
ure with the backup capacitor low or dead. Check by disconnecting
power and monitoring how long the capacitor keeps the time of day in
the display. Typically, the capacitor will maintain the time and programs
for 5 days.
PROBLEM: Time of day was set while holding the
but days are still flashing.
SOLUTION: Current day of week was not set while holding down
the
key. See "SETTING THE TIME"
PROBLEM: It is 10AM and a ON program for 8AM was entered, but
the output is not ON. Display shows the

TESTING UNIT
■
After the unit has been programmed you may want to check if it will
perform ON/OFF switching at the correct times. To accomplish this test
simply change the current time to 1 minute before the actual pro-
grammed switching event time. For example if the ON time programmed
is at 8:00AM (MON-SUN) and the OFF time programmed is at 5:00PM
(MON-SUN) then first check the ON event by changing the current time
to 7:59AM. The unit will display as follows (see setting the time section):
1 Minute
Later >>>>
Make sure
the Auto OFF
Symbol
appears.
To check the OFF event change the current time to 4:59PM. The unit will
display as follows (see setting the time section):
1 Minute
Later >>>>
Make sure
the Auto ON
Symbol
appears.
This process verifies that the unit will switch at the proper programmed
times. Now simply change the time to the actual current time.
