| 4 | Output 2 (normally closed) |
| 5 | Time range selector |
| 6 | Time adjustment (MS) |
| 7 | Time adjustment (S) |
| 8 | Time adjustment (M) |
| 9 | Time adjustment (H) |
| 10 | Control input 1 |
| 11 | Control input 2 |
The timing functions and wiring connections may vary depending on the mode of operation, but here are some examples:
On-Delay Mode
In the on-delay mode, the output contact(s) are closed after a preset delay from the initiation of the input signal. The time delay can be adjusted by the time adjustment knobs or switches. The wiring connections for the on-delay mode are as follows:
- Connect the input voltage to pins 1 and 2.
- Connect the load to pins 3 and 4.
- Connect the control input(s) to pins 10 and/or 11.
- Set the time range selector to the desired range.
- Adjust the time delay to the desired value.
Off-Delay Mode
In the off-delay mode, the output contact(s) are opened after a preset delay from the removal of the input signal. The time delay can be adjusted by the time adjustment knobs or switches. The wiring connections for the off-delay mode are as follows:
- Connect the input voltage to pins 1 and 2.
- Connect the load to pins 3 and 4.
- Connect the control input(s) to pins 10 and/or 11.
- Set the time range selector to the desired range.
- Adjust the time delay to the desired value.
