There are three main components of
Series 7000 Timing Relays:
Timing Head circulates air through a
variable length to provide linearly
adjustable timing. Patented design pro-
vides easy adjustment and long service
life under severe operating conditions.
Precision-Wound Potted Coil
Total sealing without external leads
eliminates moisture problems, gives
maximum insulation value.
Snap-Action Switch Assembly —
custom-designed over-center mecha-
nism provides snap action. Standard
switches are DPDT arrangement.
Each of these subassemblies forms
self-contained modules assembled at
the factory with the other two to afford
a wide choice of operating types, coil
voltages, and timing ranges.
The squared design with front terminals
and rear mounting permits the grouping of
Series 7000 units side-by-side in mini-
mum panel space. Auxiliary switches may
be added in the base of the unit, without
affecting the overall width or depth.
Operation
Two basic operating types are available.
“On-Delay” models provide a delay period
on energization, at the end of which the
switch transfers the load from one set of
contacts to another. De-energizing the
unit during the delay period immediately
recycles the unit, readying it for another
full delay period on re-energization.
In "Off-Delay" models the switch trans-
fers the load immediately upon energiza-
tion and the delay period does not begin
until the unit is de-energized. At the end
of the delay period the switch returns to
its original position. Re-energizing the
unit during the delay period immediately
resets the timing, readying it for another
full delay period on de-energization.
No power is required during the timing
period, providing a true off delay.
In addition to these basic operating types,
“Double-Head” models offer sequential
delays on pull-in and drop-out in one
unit. With the addition of auxiliary
switches the basic models provide two-
step timing.
Note: Seismic & radiation tested
E7000 models are available.

Applying voltage to the coil (L1-L2) for
at least 50 msec starts a time delay
lasting for the preset time. During this
period the normally closed contacts
(3-5 and 4-6) remain closed. At the end
of the delay period the normally closed
contacts break and the normally open
contacts (1-5 and 2-6) make. The
contacts remain in this transferred
position until the coil is deenergized,
at which time the switch returns to its
original position.
De-energizing the coil, either during or
after the delay period, will recycle the
unit within 50 msec.
It will then provide a full delay period
upon re-energization, regardless of how
often the coil voltage is interrupted
before the unit has been permitted to
"time-out" to its full delay setting.
Off-delay model 7022 (delay on dropout)
Applying voltage to the coil (for at least
50 msec) will transfer the switch,
breaking the normally closed contacts
(1-5 and 2-6), and making the normally
open contacts (3-5 and 4-6). Contacts
remain in this transferred position as long
as the coil is energized. The time delay
begins immediately upon de-energization.
At the end of the delay period the switch
returns to its normal position.
Re-energizing the coil during the delay
period will immediately return the timing
mechanism to a point where it will pro-
vide a full delay period upon subsequent
de-energization. The switch remains in
the transferred position.
n Modular assembly —
timing head, coil assembly
and switchblock are all
individual modules, with
switches field-replaceable
