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"
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 interference has disrupted the
microprocessor causing a loss of programme information.
A second, but very unlikely cause of loss of programme is a
power failure 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 programmes for 4 days, but not more
than 5 days.
PROBLEM: Time of day was set while holding the
key
down, 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 an ON event for 8AM was entered,
but the output is not ON. Display shows the
and
symbols.
SOLUTION: After programming, the timer does not "look back"
to determine if it should be ON. Press the
key (temporary
override) to turn the output ON;
appears in display.
The timer will assume automatic operation at the next
programmed event.
PROBLEM: An event for 8AM Monday through Friday was
entered,
but it will not accept it and
is flashing.
SOLUTION: The ON
or OFF
was not entered as part
of the program. ON or OFF
must be selected.
