| 328E Multi-Range Multi-Function Timer |
| Series Description: The Model 328E Multi-Range Multi-Function Timer is a versatile dial-adjusted time delay relay, which provides a choice of On-Delay, Off-Delay or interval operation for any timing period between 50 milliseconds and 10 hours. Based on a unique digital circuit, it features cycle progress annunciation and is suitable for the most demanding industrial service. |
| Series Operation: Control action of the 328 depends on how its terminal block is wired (see Wiring diagrams.) In ON-DELAY OPERATION, timing begins when the start switch is closed. The load relay contacts transfer at the end of the timed period. Reset occurs when the start switch is opened or when there is a power interruption. In OFF-DELAY OPERATION, timing begins when the start switch is opened. The load relay contacts transfer at the end of the timed period and back again at reset. Reset occurs when the start switch is closed. Control action of all loads is delayed, either closed-closed-open or open-open-closed. In INTERVAL CONTROL, timing begins when the start switch is closed. The load relay contacts transfer at the beginning and at the end of the timed period, thus providing true interval control, either open-closed-open or closed-open-closed. The start signal may be either sustained or momentary; in the latter case, the start signal is latched in by wiring it to one of the load relays two sets of contacts. Power interruption resets the timer. |
