Design & Construction

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.

Consult factory for detailed

information.

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

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.
