the Live and Switched Live are at different positions. Lights will stay on until the last timer goes off). Timing Screw DIAGRAM 2 DIAGRAM 3 Typical Circuit for Corridor Lighting Typical Circuit for Staircase Lighting where (i.e. 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. Continue with the adjustment until the desired NO - Normally Open time delay is reached. 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. Make slight adjustments from there, checking the time delay after each adjustment. Start by turning the timing screw so that its level with the top of the screw thread. For accuracy slight rotation of the timing screw is needed when setting the time delay. Close attention must be paid when making adjustment. 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. DIAGRAM 1 Single contact timers only have one 3. It is normal to occasionally see a ash when the switch contacts make or break. The plunger will gradually return to its normal position during the time delay. Operation: The switch is operated by pressing the plunger in to make or break the circuit. Avoid over tightening the mounting screws as this may cause the switch cover to distort and lock the plunger in the ON position. Any additional mounting lugs found on a metal box must be ground off in case it causes an obstruction or short circuit with unit. Mounting: The 400A is ideally suitable for mounting on most standard square boxes with two mounting lugs. Energy saving makes sound economical sense in light of legislation, such as the European Directive on Integrated Pollution Prevention and Control and the Climate Change Levy.12907 ELKAY 400A COLUMBUS TIMER INSTRUCTIONSv5 Layout 1 16:50 columbus timer Installation Instructions PRODUCT: 400A SINGLE CONTACT PUSH BUTTON TIMER PRODUCT: 400A-3 DOUBLE CONTACT PUSH BUTTON TIMER Incandescent 6A Compact Fluorescent 3A (6 ttings max) Resistive 6A Fluorescent 3A (6 ttings max) Voltage 230Vac Time Delay 5 sec - 5 min The Columbustimer is part of the Elkay family of time switches and detectors which save energy and increase convenience in and around your home or business premises. They can be pre-set during installation, with run times ranging from 1 second up to 2 hours. Other Energy Management Products available from Elkay Electrical include pneumatic and electronic timers, electronic PIR timers and electronic touch timers. The units are compatible with 25mm deep single gang BS accessory plate.

An On/Off button permits the user to cancel the timing period at any stage during operation, if required. It can handle a powerful 20 Amp output rating for heating, ideal to control immersion heaters and panel heaters, while it can also be used for ventilation fans and lighting.

Adjustable in 15 minute increments, the unit has a time range from 15 minutes up to 2 hours and an intelligent memory allows the timer to remember the last set time period. The electronic run-back timer allows an appliance to be powered for a set period of time and via an easy-to-read LED display clearly shows the user how much runtime is left remaining. They can provide significant energy savings over a relatively short period of time, particularly when used to control 3kW electric heaters, soon paying back the initial cost of the timers. Use of Energy Saving Timers alleviates the problem of electrical appliances, such as heaters or ventilation systems, being left on continuously. Left to the control of occasional users electrical heaters are often left on when a room is not being used, unnecessarily adding to the electric bill and simply wasting valuable energy.
