Timer Function Descriptions
A . Delay On Operate
Output relay turned on at end of programmed time interval which is started
by CONTROL input or power-on with CONTROL on. Relay turned off by
RESET input until next cycle is started. With CONTROL on, turning RESET
off restarts timing
B. Delay On Release
Output relay turned on with CONTROL input and remains on for programmed
time interval following removal of CONTROL. During time interval after
release of CONTROL, RESET turns relay off until cycle restarted with
reapplication of CONTROL. With CONTROL on, relay is held off while
RESET is activated.
C. Interval On
Output relay turned on for programmed time interval by CONTROL or power-
on with CONTROL on. RESET turns relay off until next cycle is started, and
does not restart timing when RESET is removed.
D. Control-Off Interval On
Output relay turned on for programmed time interval by turn-off of CON-
TROL. RESET turns relay off until next cycle is started, and does not restart
timing when RESET is removed.
E. Recycle
Output relay turned on at end of programmed time interval which is started
by momentary CONTROL input or power-on with CONTROL on. Relay stays
on for equal time interval, then turns off and cycle is repeated on a free-
running basis until terminated by momentary RESET, turning relay off. With
CONTROL on, turning RESET off restarts cycle.
F. Single Cycle
Output relay turned on at end of programmed time interval which is
Counter Function Descriptions
CO – Operate at Preset Count – Normal Mode
After initializing by momentary activation of RESET input, each on/off signal
at COUNT (CONTROL) input increments displayed count in upcounting
manner from initial 000 value until preset count, set by thumbwheel
switches, is reached and output relay turns on. Additional inputs continue to
increment displayed count. Continued counting past maximum count (999)
results in a “wrap-around” effect to 000, followed by contrinued up-counting.
Activation of RESET input turns relay off and resets count to zero.
started by momentary CONTROL input or power-on with CONTROL
on. Relay stays on for equal time interval, then turns off. RESET
terminates timing and turns relay off. Turning RESET off does not restart
timing.
G. Control On-Off Interval On (Watch Dog Timer)
Output relay turned on and programmed time interval started or restarted
by change of CONTROL input. RESET turns relay off and stops timing.
Turning RESET off does not restart timing.
H. Control On-Off Delay
Output relay turned on at end of programmed timing interval which is
started or restarted by change of CONTROL input. If relay is on, turn-off
of relay occurs at end of programmed time interval which is started or
restarted by change of CONTROL input. RESET turns relay off and stops
timing. Turning RESET off does not restart timing.
I. Pulse
Output relay turned on at end of programmed time interval, which is
started by CONTROL input, for 0.5 second duration, and continues in
pulsed mode at programmed time interval with fixed 0.5 second on-time.
Turning CONTROL off turns relay off and stops timing. RESET turns relay
off and inhibits operation. With CONTROL on, removal of RESET restarts
timing.
J. Cumulative Delay On Operate
Output relay turned on at completion of total accumulate CONTROL input
duration equal to programmed time. Turning CONTROL off before
accumulation of programmed time results in measured time total being
held until CONTROL is again turned on and total programmed time value
is reached. RESET input resets time value to zero and turns relay off if
energized. Turning RESET off restarts timing if CONTROL is on.
CR – Release at Preset Count – Normal Mode
Initializing by momentary activation of RESET input turns relay on. Operation
is similar to CO (Operate at Preset Count) except relay turns off at a preset
count.
CO or CR – Divide-by-10 Mode
Operation is as described previously, except count is incremented for every
10 on/off input signals for a maximum presettable count of 9,990.
CO or CR – Divide-by-100 Mode
Operation is as described previously, except count is incremented for every
100 on/off input signals for a maximum presettable count of 99,900.
