MULTIPLE TIMING MODES: The 407 is available with selectable On-
Delay, Off-Delay or Interval timing modes. These timing modes energize
a set of DPDT output contacts. When in the On-Delay mode, the 407 be-
gins timing when the timer is energized. In On-Delay mode, the contacts
transfer at time out. When in the Off-Delay mode, the 407 begins timing
when the Start input is de-energized. In Off-Delay mode, the contacts
transfer at time out. When in the Interval mode, the contacts transfer
when the timer is energized. In Interval mode, the contacts release at
time out.

UNIVERSAL POWER SUPPLY: All 407 timers can be powered using
24-240 VAC or 24 VDC power, greatly simplifying ordering and inventory
management of replacement units.

HIGH ACCURACY: The 407’s timing circuit is not a simple RC circuit.
It utilizes the sophIstication of a proprietary integrated circuit that
includes counting technology along with a stable oscillator to provide
repeatable time delays.

1/16 DIN HOUSING: The 48mm2 (1/16 DIN) housing is compact. The
407 is mounted in an 11-pin round socket. With an optional mounting
clip, the 407 can be panel mounted.

The Dial on the 407 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 407 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 progresses; 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).

The 407C Directly Replaces 407B and 407A

Special note for Off-Delay operation: When operated from AC, the
start switch must be of a dr y contact type such as a relay contact or
mechanical switch. When operated from DC, the start switch can be
a dry contact type such as a relay contact or mechanical switch. In
addition, a solid-state device may be used as long as its saturation
voltage drop is less than 1.5 VDC at 50mA.

OPERATIONS

Timing begins when the start switch is closed (ON-delay and INT
modes) or opened (OFF-delay mode). 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, the LED repeatedly blinks once followed by a pause. For
the second 10%, it blinks twice and so on indicating he cycle progress.
The LED flashes rapidly and continuously after time out.

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.

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 407B then resets and is ready for
another cycle.

OFF-DELAY MODE: Power must be applied to the timer before and
during timing (terminals #10 & 2). Upon closure of the start switch,
the DPDT relay transfers its contacts. The timing begins when the start
switch is opened. The relay remains energized during timing. At time
out, the relay de-energizes.
