To increase the versatility of the basic timer models, auxiliary switches may

be added to either on-delay or off-delay types. They switch additional circuits,

provide two-step timing action, or furnish electrical interlock for sustained coil

energization from a momentary impulse, depending on the type selected and

its adjustment. Because of their simple attachment and adjustment features,

they can be installed at the factory or in the field, by any competent mechanic.

All auxiliary switches are SPDT with UL listings of 10A @ 125, 250, or 480 VAC.

A maximum of one Code T or two Code L auxiliary switches may be added to

each relay. The L or LL switch is available with on-delay relays only. The T

switch is available with both the on-delay and off-delay relays.

Auxiliary Switch Options for On-Delay

Instant Transfer (Auxiliary Switch Code L, maximum of 2 per relay.)

1. Energizing coil begins time delay and transfers auxiliary switch.

2. Main switch transfers after total preset delay.

3. De-energizing coil resets both switches instantly.

Auxiliary switch is nonadjustable.

Two-Step Timing (Auxiliary Switch Code T, maximum of 1 per relay.)

1. Energizing coil begins time delay.

2. After first delay auxiliary switch transfers.

3. Main switch transfers after total preset delay.

4. De-energizing coil resets both switches instantly. First delay is

independently adjustable, up to 30% of overall delay.

(Recommended maximum 100 seconds.)

Auxiliary Switch Options for Off-Delay

In these models the same auxiliary switch provides either two-step timing or

instant transfer action, depending on the adjustment of the actuator.

Two-Step Timing (Auxiliary Switch Code T, maximum of 1 per relay.)

1. Energizing coil transfers main and auxiliary switches instantly.

2. De-energizing coil begins time delay.

3. After first delay auxiliary switch transfers.

4. Main switch transfers after total preset delay. First delay is independently

adjustable, up to 30% of overall delay. (Recommended maximum 100 sec-

onds.)

Instant Transfer (Auxiliary Switch Code L, maximum of 1 per relay.)

1. Energizing coil transfers main and auxiliary switches instantly.

2. De-energizing coil resets auxiliary switch and begins time delay.

3. Main switch transfers after total preset delay.

Auxiliary switch is factory adjusted to give instant transfer operation, but may

be easily adjusted in the field to provide two-step timing.

Auxiliary switch options

On-delay, off-delay model 7032 (double head)

The Double Head model provides delayed switch transfer on

energization of its coil, followed by delayed resetting upon coil de-

energization. Each delay period is independently adjustable.

In new circuit designs or the improvement of existing controls now

using two or more conventional timers, the Double Head unit offers distinct

advantages.

Its compact design saves precious panel space, while the simplified

wiring reduces costly interconnection.

Four pole model 7014. 7024

With the addition of an extra switch block at the bottom of the basic unit,

this version of the Series 7000 offers four pole switch capacity with simul-

taneous timing or two-step timing. The two-step operation is achieved by

factory adjustment to your specifications.

For two-step operation, a maximum timing ratio between upper and

lower switches of 3:2 is recommended. Once adjusted at the factory, this

ratio remains constant regardless of changes in dial settings. (Ex: If upper

switch transfer is set on dial at 60 sec., minimum time on lower switch

should be 40 sec.)

This Series 7000 unit offers many of the performance features found in

basic models - voltage ranges, timing and switch capacities are virtually iden-

tical.

Four pole models add approximately 1-1/4" to the maximum height of the

basic model, approximately 1/8" to the depth. They are designed for vertical

operation only.

Surge/transient protection option

Features

• Protect electronic control circuits

from voltage transients generated

by the timer coil.

• Fast response to the rapidly rising

back E.M.F.

• High performance clamping voltage

characteristics.

• UL recognized, (except varistor and

coil together).

• Timer NOT polarity sensitive.

The Surge/Transient Protection Option protects electronic control circuits from

transients and surges which are generated when the timer coil is activated.

Built with a minimum of moving parts, the unit provides a fast response to rap-

idly rising voltage transients. The accurate, precision-made device is not polari-

ty sensitive and permits the user to initiate, delay, sequence and program

equipment actions over a wide range of applications under the most severe

operating conditions.

It consists of a specially modified coil case, varistor, varistor cover, terminal

extensions and cup washers so that normal terminations can be used. The

varistor will not affect the operating characteristics of the 7000 Timer. The

varistor has bilateral and symmetrical voltage and current characteristics and

therefore can be used in place of the back-to-back zener diodes. This charac-

teristic also means that the coil will not be polarity sensitive.
