Time intervals

Range 1           0-60 seconds, adjusted by the potentiometer

Range 2           1-60 minutes, selected by plug in link JP2 and adjusted by the potentiometer.

Two modes of operation are provided and are selected by plug in link JP1.

Mode 1

Link pins 1 and 2 on JP1. The relay activates for the timed period. In Mode 1there are 3 options.

1. With JP4 link out, apply a momentary trigger. The relay will activate for the timed period and then de-energise.
2. With JP4 link in, apply a momentary trigger. The relay will activate for the timed period and then de-energise. The timer will lock out until reset pins JP3 are shorted.
3. With JP4 link out, apply a permanent trigger. The relay will activate for the timed period and then de-energise.

If the trigger is still present, after approximately 3 seconds the timer will start again, creating a continuous cycle of operation. The timer will reset after the trigger has been removed.

Mode 2

Link pins 2 and 3 on JP1. The relay activates after the timed period. In Mode 2 there are 3 options.

1. With JP4 out, apply a momentary trigger. The relay activates momentarily after the timed period.
2. With JP4 link in, apply a momentary trigger. The relay will latch on after the timed period until reset pins JP3 are shorted.
3. With JP4 link out, apply a permanent trigger. The relay will activate after the timed period for approximately 3 seconds and then de-energise. If the trigger is still present the timer will start again, creating a continuous cycle of operation. The timer will reset after the trigger has been removed.

Trigger inputs

The timer will start when an input is applied to the ‘T’ terminal. The input can be a brief pulse or a continuous signal.
