| 305E Motor-Driven Analog Reset Timer |
| Series Description: The 305E is a versatile reset timer that provides delay, interval, or pulse timing functions for up to 7 load circuits through two instantaneous and two delayed switches. Its plug-in design and cycle progress indication make it user-friendly and reliable. With an average mechanical life expectancy of over 5,000,000 operations before the first failure, the 305E reset timer stands as the leader in its class for endurance and durability. |
| Series Operation: The 305 is a synchronous motor-driven timer with an electrically-operated clutch equipped either for ON-Delay or OFF-Delay operation. ON-DELAY: When power is applied (start signal on), the clutch solenoid is energized. Two things happen immediately and simultaneously, the instantaneous switches transfer from one set of contacts to the other, and the motor begins to drive the cycle progress pointer toward zero. At the end of the timed period, the pointer trips one of the delayed switches, a brief time later (about 1/2% of full scale), the other delayed switch is tripped, stopping the timer motor but leaving the clutch engaged. The timer does not reset until power to the clutch is removed. OFF-DELAY: Timing starts when power is removed (start signal off), from the spring-loaded, normally engaged clutch. The timer is reset when power is restored to the clutch solenoid; simultaneously, the instantaneous contacts are tripped. Action of the delayed contacts is the same as with ON-Delay timers. A power outage stops the motor but does not reset the OFF-Delay 305E. |
