OPERATION
Timing begins when the start switch is closed.This starts an oscillator
which runs at a frequency determined by the time setting. A fixed number
of counts from the oscillator determines the end of the timing cycle.The
time required to accomplish this depends upon the oscillator frequency.
During timing, an LED located on the dial face blinks.For the first 10% of
the cycle, LED repeatedly blinks once followed by a pause.For the second
10%, it blinks twice and so on indicating the cycle progress.The LED flashes rapidly and continuously after time out.

The instantaneous contacts (3-1-4) transfer immediately after the start
switch is closed.The delayed contacts (6-8-5) transfer after the timing

ON DELAY MODE - At time out, the DPDT relay transfers its contacts.
These contacts remain transferred until the start switch is opened or power
is removed by some other means.The 405A then resets and is ready for
another cycle.
INTERVAL MODE - When the start switch is closed, the DPDT relay transfers its contacts.The contacts remain transferred until time out.The timer
will not start again until the start switch is opened or power is removed by
some other means.The 405A then resets and is ready for another cycle.

PANEL MOUNTING:
To panel mount, cut a 1 25/32” square cutout (1.77”)
1. Insert the 405A through the panel from the front
with the plug going through the cutout first.
2. While holding the 405A in place, push the mounting bracket over the 405A from the back and snap
into place as shown in the panel mounting dimensions drawing.
3. When using the 405A in a panel mounted configuration, the optional 03192614500 plug-on socket
can be used. See illustration below.
SETTING THE RANGE AND TIMING MODE:
Refer to the drawing.Using a small screwdriver inserted
into the adjusting slot as shown, rotate the range or
mode adjusting switch.The range selected will appear
through the window at the top of the dial face.The timing
mode is indicated on the housing.
Note:To prevent a hazard to personnel or property,
change range and/or timing mode with electrical
power off.
