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.
