Valve Camshaft - Autotrol 255 Manuel D'utilisation

Controller Location
The 700 Series controllers are designed to be mounted on the valve or attached to a flat
surface. Installations that do not provide easy access to the valve can have the control-
ler mounted for remote operation.
A remote mount connection, P/N 1256257, is available for the 700 Series controller.

Valve Camshaft

The front end of the camshaft has an indicator cup. The cup has slots in the outer periphery
and numbers on the inside face (Figure 13,14).
The numbers can be seen with the cover off, from the front over the top of the controller.
The number at the top indicates which regeneration cycle is currently in progress.
