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

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.

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.

Counter Function Descriptions

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.
