Auxiliary Switch Options

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 fur-

nish electrical interlock for sustained

coil energization from a momentary

impulse, depending on the type selected

and its adjustment. They are installed at

the factory. 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 independ-

ently adjustable, up to 30% of overall

delay. (Recommended maximum

100 seconds.)

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. Two-step

timing may be set at the factory to cus-

tomer specification up to a 3:2 ratio.

The Double Head model provides delayed switch transfer on

energization of its coil, and 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 panel space, while the simplified

wiring reduces costly interconnection.

On-delay, Off-delay Model 7032 (Double Head)

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 simultaneous 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 ad-

justed 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 fea-

tures found in basic models — voltage ranges, timing and

switch capacities.

Four pole models add approximately 1-1/4" to the maxi-

mum height of the basic model, approximately 1/8" to the

depth. They are designed for vertical operation only.
