Mounting: The 400A is ideally suitable for mounting on most standard square boxes with two mounting lugs. Any additional mounting lugs found on a metal box must be ground off in case it causes an obstruction or short circuit with unit. Avoid over tightening the mounting screws as this may cause the switch cover to distort and lock the plunger in the ON position. 2. Operation: The switch is operated by pressing the plunger in to make or break the circuit. The plunger will gradually return to its normal position during the time delay. It is normal to occasionally see a ash when the switch contacts make or break. DIAGRAM 1 Single contact timers only have one 3. Timing Adjustment: Delay timing is set and adjusted by turning the timing screw at the back of the unit, clockwise to increase and anti-clockwise to set of contacts tted. decrease the time delay. Close attention must be paid when making adjustment. For accuracy slight rotation of the timing screw is needed when setting the time delay. Start by turning the timing screw so that its level with the top of the screw thread. Make slight adjustments from there, checking the time delay after each adjustment. Sometime this slight adjustment of the timing screw may not result in any changes to the time delay and this is due to the mechanical nature of the timing COM - Common mechanism. Continue with the adjustment until the desired NO - Normally Open time delay is reached. Please note due to the mechanical setting, there may be a variation in the time delay from one NC - Normally Closed push to the next.
