| Control Switch Jumpered on TD-7 Digital-Set Time Delay Relay |
| Issue |
| What happens if I put a jumper across the control switch terminals (Pins 5 & 6) on the TD-7 Digital-Set time delay relay, but I have the function set to On Delay, which doesn't need a Control Switch to initiate it? Will the unit operate satisfactorily? |
| Solution/Resolution |
| No control switch is required when the unit is set to On Delay, Interval On or Flasher. However, if for some reason Pins 5 & 6 have been jumpered before Input Voltage is applied, the unit will operate without any problems. The software program is written to ignore Pins 5 & 6 when either of these three functions are selected using the first pushbutton-thumbwheel. Of course, when in either the Off Delay or Single Shot mode, a dry contact control switch must be connected to Pins 5 & 6 to initiate the function.
