On-delay, Off-delay Model 7032 (Double Head)
The Double Head model provides delayed switch trans fer on
energization of its coil, and de layed resetting upon coil de-
energization. Each delay period is in dep end ent ly adjustable.
In new circuit designs or the improvement of ex ist ing
cont rols now using two or more conventional time rs, the
Double Head unit offers distinct advantages.
Its compact design saves panel space, while the simplified
wiring reduces costly in ter con nec tion.

On-delay Model 7014, Off-delay Model 7024
With the addition of an extra switch block at the bot tom of
the basic unit, this version of the Series 7000 offers four
pole switch capacity with simul taneous timi ng or two-step
timing. The two-step operation is achieved by factory
adjustment to your specifications.
For two-step operation, a maximum timing ratio be tween
upper and lower switches of 3:2 is rec omm end ed. Once ad-
just ed at the factory, this ratio remains con stant regardless
of changes in dial settings. (Ex: If up per 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 per for m ance fea-
tures found in basic models voltage ranges, timing and
switch capacities.
Four pole models add approximately 1-1/4" to the max i-
mum height of the basic model, approximately 1/8" to the
depth. They are designed for vertical op er a tion only.
