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.
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.
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.
