MODEL#: EJWT

The control will cycle loads on/off based on the setting of the control knobs as long as input power is supplied. The control will start with the on time cycle after initial power is applied

to the control. The unit is simple to set consisting of only two dials: one CYCLE TIME dial to set time durations and one % ON dial to set the percentage of ON time for the selected

duration.

Total cycle duration can be set from 15 seconds minimum to 24 hours maximum, The % ON setting for each cycle duration is independently adjustable from 0% (continuous OFF) to

100% (continuous ON) in 32 increments

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 EJWT 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. Securely attach the timer to Tork’s NEMA 4X (for indoor use only)

non-metallic enclosure with the included screws.

ON/OFF TIME SETTING INSTRUCTIONS FOR LOADS USING NORMALLY OPEN (NO) RELAY CONTACTS To set the ON time: 1. Select the total cycle time between 15 seconds and 24 hours, using the dial on the left. 2. Set ON time duration using the right dial (% ON). The ON time duration is a percentage of the total cycle time chosen in the previous step. Set percentage to desired length of time that the load (fan, light, etc,) is to be turned on.

INSTRUCTIONS POUR LE RÉGLAGE DES PÉRIODES DE MISE EN MARCHE ET D’ARRÊT POUR LES CHARGES UTILISANT DES CONTACTS DE RELAIS NORMALEMENT OUVERTS Réglage de la période de MISE EN MARCHE : 1. Déterminez la durée totale du cycle (entre 15 secondes et 24 heures) à l’aide du cadran de gauche. 2. Réglez le taux de fonctionnement (% ON) à l’aide du cadran de droite. Ce taux correspond à un pourcentage de la durée totale du cycle établie à l’étape précédente.
