Timer Function Descriptions
Repeat: Output relay is turned on at end of programmed time interval which is
started by application of input power. Relay stays on for equal time interval, then
turns off and cycle is repeated on a free-running basis with equal on and off times
until terminated by removal of input power. LED is flashing when output relay is
off and on continuously when the relay is on. Applying CONTROL input during
LED to show time status.
timing will have no effect on timing or the state of the relay.
See functional explanation for details.
One Shot: Output relay is turned on by applying CONTROL input with input
voltage present or application of input voltage with the CONTROL input on.
REPEAT
Immediately upon either, timing is initiated with the output relay turning off at the

OFF DELAY completion of the selected time interval. Applying CONTROL input after time out
INTERVAL
will reset the timer, turn on the output relay and initiate another time interval. LED
ON DELAY
is on continuously when output relay is off and flashes when the relay is on.
Applying CONTROL input during timing will have no effect on timing or the state
of the relay.
Off Delay: Output relay is turned on by applying CONTROL input with input
voltage present or application of input voltage with the CONTROL input on. The
time interval will be started by removing the CONTROL input with the output relay

turning off at completion of the time interval. Reapplying the CONTROL during
timing will reset the time to zero and inhibit timing until removed. LED is off when
CONTROL input is on, flashing during timing and on continuously when the output
relay is off.
