Velleman 1S – 60H PULSE-PAUSE TIMER
1. Pulse and pause adjustments are not working. I want to turn off and on - a 12 pump for short periods of time 1-2 minutes . When power is applied , the pump will cycle on and off, after a 20 pulses, the motor will turn on and not stop. The jumper are set for minutes and the the adjustment knobs are at the middle. The two other jumpers are both set, single shot and loop. Any clues thanks.
