INSTANTANEOUS & DELAYED: A version of the 405 is available with

one set of SPDT instantaneous contacts and one set of SPDT delayed

contacts. The instantaneous contacts transfer as soon as the timer is

powered. The delayed contacts transfer at time out. This contact ar-

rangement can be used to replace many conventional timers.

ON DELAY/INTERVAL TIMING MODE VERSION: A version of the 405

is available with selectable ON-delay or Interval timing modes. This

version has a set of DPDT output contacts. When in the ON-delay

mode, the contacts transfer at time out. When in the Interval mode, the

contacts transfer when power is applied and release at time out.

UNIVERSAL POWER: All 405 timers can be powered using 24-240 VAC

or 24 VDC power, greatly simplifying ordering and inventory manage-

ment of replacement units.

1/16 DIN HOUSING: The 48mm2 (1/16 DIN) housing is compact

design. The 405 is mounted in an 8-pin round (octal) socket. With an

optional mounting clip, the 405 can be panel mounted.

The Dial on the 405 is extra-large and is easy to read. When fractional

ranges are selected, decimal points are clearly indicated.

The Mode select and Range select switches are located on the side of

the unit, so that when panel mounted, these switches are not acces-

sible to the operator. This tamper proof feature prevents unauthorized

or hazardous changes to the timing mode and range from being made.

CYCLE PROGRESS INDICATION: The 405 LED indicator provides a

unique and effective method of cycle progress indication. Off before

timing, the LED blinks at an ever increasing rate as the cycle pro-

gresses: once every 3-1/2 seconds during the first 10% of the cycle,

twice during the second 10%, and so on. At time out, the LED pulses

at a high rate. (In the 1, 5, 10 and 50 second ranges, the LED is OFF

before timing, steady ON during timing, and pulsing ON after time-out).

Timing begins when the start switch is closed. This starts an oscilla-

tor 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.

MODEL...F1X

The instantaneous contacts (3-1-4) transfer immediately after the

start switch is closed. The delayed contacts (6-8-5) transfer after the

timing cycle indicated on the front dial setting. Both contacts remain

transferred until the unit is reset.

MODEL...F2X

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 405 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 405 then resets and is ready for

another cycle.
