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. 12 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. 129 Catalog 5-1773450-5 Dimensions are shown for Dimensions are in millimeters USA: +1 800 522 6752 For additional support numbers Revised 3-13 reference purposes only. unless otherwise specified.
