Hi just a quick question here, i have to make a small control panel which will have a N/C contactor which will open by the use of a keyswitch to test the batteries of a charging unit. The consultants have asked for a power on indicator from the two supplies operated by the contactor, which is fine, they will simply be supplied by the circuits inside the box. Their will also be an indicator which will only illuminate once the keyswitch has been operated to indicate that the system is on test. This is all great but now the consultants have thrown a lamp test button into the mix, so i am wondering what is the logical function of this test switch. Would you normally turn off lamps that are normally on to test them , or would you just turn on lamps that are normally off .
The lamps are going to be LEDs anyway but just wanted to know your thoughts on this .
