At the end of timing, the load is energized. he timer is permanently supplied. At the closure of contact S, the load is energised until the set time has elapsed, after the opening of S. If S is reclosed during timing, the output will remain energised. Command contact S should be isolated from any other circuit. Power supply has to be closed when operating S he timer is permanently supplied. he load is alternatively de-energised and energised repeatedly to the set time. Function D : Pause start cycle (Standard Supply) Function Di : Pulse start cycle Function B & Function H Function B : Single Shot he timer is permanently supplied. At the closure of the command contact S (either fleeting or maintained contact), the load is energized. he load de-energized at the end of timing. Function H : Interval imer At the closure of (Supply ON), the load is energised and timing starts. At the end of timing, the load de-energised Function Q he star relay energizes when supply is applied to the timer and timing begins. After the timing, the star relay deenergises. After a pause of about 00ms, the delta relay energizes and will be maintained. Encapsulated imer for Compressor and heat Pump When a compressor is stopped by the hermostat, it should not restart immediately on full load. A timer of 3 to 5 minutes is needed to equalise the Interior pressure in the system, or to avoid a sudden drop in the latter. In other words, the timer is needed to prevant reset of the thermostat and to ensure optimal opertion of the equipment. For this application. BIL has developed a special low-cost timer with only terminals, the SAS-CB (load in series with timer) Note : At the first supply "ON" the compressor starts instantaneously without loss of time Function A Function C Function D Function B Function Q Encapsulated imer for Compressor and heat Pump C C i S Function Di Function H
