ON DELAY TIMER

MODEL#: E500T

The E500T is an ON delay timer which allows for a set time interval to elapse before the load connected to the timer is powered ON. An external maintained contact switch (by others) is used to start the
delay time. Once turned ON, the load will remain on until the external switch is opened.

It has an adjustable rotary dial which contains 32 precisely defined positions, allowing for interval durations from five (5) seconds minimum to 3 hours maximum. Continuous ON and continuous OFF
settings are included.

INSTALLATION & WIRING INSTRUCTIONS

Note: Wiring connections are made to a six-position: terminal block.
All terminals accept AWG #18 to AWG #12 wire.

1. Turn off all power to the timer circuit at the distribution panel before
beginning the installation.

2. The E500T box contains knockouts on two sides. Determine the most
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 external 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) non­metallic enclosure with the included screws
