⚫ 5-Year Unconditional Warranty
DESCRIPTION
The Model 334 and 364 Delayed One-Shot Timers are
functionally interchangeable. The Model 334 is a DPDT
potentiometer (knob-adjust) timer while the Model 364 is a
DPDT, high-accuracy digital input timer. Solid-state timing
circuits in each model drive an internal electromechanical
relay.
Upon application of power, the unit will start the OFF
delay. After the OFF delay times out, the relay will
energize for the ON time. When the ON time expires, the
relay will de-energize and all timing will stop. Power must
be removed and reapplied to begin timing again.
An “SG” version of this model is available using silver with
gold flash contacts.
Models 334 and 364 are UL Recognized and CSA
Certified.

GENERAL SAFETY
POTENTIALLY HAZARDOUS VOLTAGES ARE PRESENT AT THE TERMINALS OF THE MODEL 334 OR 364.
ALL ELECTRICAL POWER SHOULD BE REMOVED WHEN CONNECTING OR DISCONNECTING WIRING.
THIS DEVICE SHOULD BE INSTALLED AND SERVICED BY QUALIFIED PERSONNEL.
Installation Instructions
OPERATION
When the supply voltage is applied, the OFF cycle begins
timing. Upon completion of the delay, the internal relay
energizes and the ON cycle begins timing (ON and OFF
cycles can be of equal or unequal durations). When the
ON time expires, the relay will de-energize and all timing
will stop. Power must be removed and reapplied to begin
timing again.

PIN DIAGRAM
The Models 334 and 364 Delayed One-Shot Timers
require a standard 8-pin socket for mounting, and use a
standard pin configuration. Refer to the pin diagram
below, or on the timer, for terminal connections.
An LED on top of the unit provides a quick visual indicator of
the relay’s status.

ADJUSTMENT PROCEDURE - Model 364
The procedure to determine the switch selections for the
digital Model 364 Delayed One-Shot Timer requires some
simple calculations, which can be completed easily after
the basic steps are explained.
1. Convert the time required to minutes, seconds, or
tenths of seconds, depending upon the timing range
of the unit. For example:
7 hrs, 32 min = (7x60)+32 = 452 minutes
15 min, 2 secs = (15x60)+2 = 902 seconds
6.7 secs = (6.7*10) = 67 tenths of a second
2. 2. To set a desired delay period on the timer, just
add the values of the selected dip switches (beginning
with the largest value first) to total the desired time.
e.g. #1: 100 seconds OFF; 900 seconds ON
e.g. #2: 5 minutes OFF; 55 minutes ON
32+16+4+2+1 = 55 minute ON delay
4+1 = 5 minute OFF delay
