Time Mark 392 Data Sheet

TIME MARK is a division of

MODEL 392

Interval/Lockout Timer

 Multiple timing & voltage ranges
 Easy to program
 5-Year Unconditional Warranty

DESCRIPTION

The Model 392 Interval Lockout Timer is useful when
you wish to de-energize the relay for a set period of time.
Power is applied to the coil all the time. The "Dry" contact
must close the initiate switch and re-open to energize the
relay for the "On" time setting. At the end of the "On" time,
the relay will de-energize and remain de-energized for the
"lockout" time period. Closing and re-opening the initiate
switch during the timing has no effect on the operation of
the relay. At the end of the "Lockout" time the relay can be
operated as before.

An “SG” version of this model is available using silver with

gold flash contacts.
The Model 392 is UL Recognized and CSA Certified.

ALL ELECTRICAL POWER SHOULD BE REMOVED WHEN CONNECTING OR DISCONNECTING WIRING.

THIS DEVICE SHOULD BE INSTALLED AND SERVICED BY QUALIFIED PERSONNEL.

Installation Instructions

OPERATION

Power is applied to the coil all the time (Pins 2 & 7). When
the initiate switch is closed, nothing happens. When the
initiate switch is opened, immediately the relay will energize

for the Interval time period. At the end of the Interval “ON”

time, the relay will de-energize and remain de-energized until
the total time period (Lockout) has elapsed.
The initiate switch opening and closing has no effect while the
relay is timing. The relay can start again only after it has
completed the total time set for the relay. If power is lost to
the coil of the timer the relay will immediately de-energize.

An LED on top of the unit provides a quick visual indicator of
the relay’s status.
