MODEL#:
The E501T is designed for interval timing for a variety of applications. This timer is user adjustable with interval durations ranging from ten (10) seconds minimum to 12 hours
maximum. Continuous ON and continuous OFF settings are included.
Timing selection is made by setting a rotary dial, which contains 32 precisely defined positions. The timing selection may be started (or stopped) from the STOP/START button on the
face of the timer or from a remote momentary switch. If a maintained switch closure is used for the remote input, the button on the face can be disabled.

convenient way to mount the box to the conduit and remove the
appropriate knockout. To secure the box to a fixed location, use at
least two of the four box mounting knockouts located on the back of
the box.
3. Wire timer for either 120 VAC or 240 VAC as shown by the wiring
diagram. Wire the load to the timer as shown in the wiring diagram,
noting the contact load type and ratings shown.
4. Connect optional trigger contacts to the timer as shown in the wiring
diagram.
5. Securely attach the timer to Tork's NEMA 4X (for indoor use only)
