Design & Construction
There are three main components of
Series 7000 Timing Relays:
Timing Head cir cu lates air through a
vari able length to provide linearly
adjustable timing. Pat ent ed design pro-
vides easy ad just ment and long service
life under severe operating con di tions.
Precision-Wound Potted Coil
Total sealing without external leads
eliminates moisture prob lems, gives
maximum insulation value.
Snap-Action Switch Assembly —
custom-de signed over-center mecha-
nism provides snap action. Standard
switches are DPDT arrangement.
Each of these subassemblies forms
self-con tained mod ules 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 switch es may
be add ed in the base of the unit, without
affecting the overall width or depth.
Operation
Two basic operating types are available.
“On-De lay” mod els provide a delay period
on energization, at the end of which the
switch transfers the load from one set of
contacts to an oth er. De-energizing the
unit dur ing the delay period im me di ate ly
recycles the unit, ready ing it for another
full de lay period on re-energization.
In "Off-Delay" models the switch trans-
fers the load im me di ate ly upon energiza-
tion and the delay period does not be gin
until the unit is de-energized. At the end
of the delay period the switch returns to
its original po si tion. Re- en er giz ing the
unit during the delay period im me di ate ly
resets the timing, ready ing 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.

On-delay model 7012 (delay on pickup)
Applying voltage to the coil (L1-L2) for
at least 50 msec starts a time delay
lasting for the preset time. During this
pe ri od the nor mal ly closed con tacts
(3-5 and 4-6) re main closed. At the end
of the delay period the nor mal ly closed
contacts break and the normally open
contacts (1-5 and 2-6) make. The
con tacts re main in this trans ferred
po si tion until the coil is deenergized,
at which time the switch re turns to its
orig i nal position.
De-energizing the coil, either dur ing or
after the de lay pe ri od, will re cy cle the
unit within 50 msec.
It will then pro vide a full delay period
upon re-energization, re gard less of how
often the coil voltage is in ter rupt ed
before the unit has been per mit ted 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 nor mal ly closed contacts
(1-5 and 2-6), and mak ing the nor mal ly
open contacts (3-5 and 4-6). Contacts
remain in this transferred position as long
as the coil is en er gized. The time delay
be gins immediately upon de-energization.
At the end of the de lay period the switch
returns to its normal po si tion.
Re-energizing the coil during the delay
period will im me di ate ly return the timing
mechanism to a point where it will pro-
vide a full delay period upon sub se quent
de-energization. The switch remains in
the transferred position.
