Time Mark 300 Data Sheet

MODEL 300

Programmable Timer

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

DESCRIPTION

The Model 300 Programma ble Timer is designed to replace
over 100 standard timers. One Model 300 can be set for one
of five functions, covers four timing ranges, and has a power
supply for any AC/DC voltage from 10 to 28 Volts or 40 to 260
Volts. An “SG” version of this model is available using silver
with gold flash contacts.

The digital design of the Model 300 provides hig h accuracy,
repeatability and response time. The output of the Model 300
is a heavy-duty SPDT electro-mechanical output relay.

Programming options are chosen by simply setting the four
DIP switches on top of the relay, and then adjusting a
potentiometer for percent of delay. A LED indicator
illuminates when the relay is energized.

The Model 300 can be set to Delay-on-Release by adding an
external jumper between pins 6 and 8 (see Installation
Instructions on reverse side).

The Model 300 is UL Recognized and CSA Certified.

READ ALL INSTRUCTIONS BEFORE INSTALLING, OPERATING OR SERVICING THIS DEVICE.

KEEP THIS DATA SHEET FOR FUTURE REFERENCE.

GENERAL SAFETY

POTENTIALLY HAZARDOUS VOLTAGES ARE PRESENT AT THE TERMINALS OF THE MODEL 300.

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

THIS DEVICE SHOULD BE INSTALLED AND SERVICED BY QUALIFIED PERSONNEL.

Installation Instructions

INSTALLATION

1. Mount the 8-pin socket in a suitable enclosure.

2. Referring to the PROGRAMMING table on the reverse
side of this sheet and PIN CONNECTIONS diagram
below, set the DIP switches for desired function and
timing range.

3. Connect the load to the appropriate relay output
terminals of the socket.

4. For the Delay-on-Release function, install a normally
open switch on terminals 5 and 6 of the socket and add
an external jumper between pins 6 and 8 (shown as a
dashed line in Pin Connections diagram below).

5. Connect the appropriate operating power to terminals 7
and 2.

PIN CONNECTIONS

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

FUNCTION DESCRIPTIONS

Interval-on-Operate: The output relay energizes when op-

erating power is applied. When the timing period elapses, the
relay de-energizes. The timer is reset by removing and
reapplying power.

Supply voltage

Output

Delay

Delay-on-Operate: The delay period begins when operating
power is applied. When the timing period elapses, the output
relay energizes. The timer is reset and restarted by removing
and reapplying power.

Supply voltage

Delay-on-Release: Operating power is continuously applied to
the timer. When the external release initiate switch is closed
the output relay energizes. When the control switch is
opened the timing period begins. If the control switch closes
before the timing period elapses, the output relay remains
energized and the timing period is reset. When the timing
period elapses, the output relay de-energizes. The timer is
restarted by re-closing the control switch.
For the Delay on Release function, you must add an external
jumper between pins 6 and 8.
