Override control Z

SKB60, SKB62..

The override control input Z can be operated in the following modes of operation:

No function

Connections

Transfer

Equal percentage or

linear

● Z-contact not

connected

● Valve stroke follows

Y-input

Shown operation modes are based on the factory setting "direct acting".

Y-input has no effect in Z-mode.

Selection of direction of operation

SKB60 (from version ..L), SKB62UA

●

With normally-closed valves, "direct acting" means that with a signal input of 0 V, the

valve closes (applies to all Siemens valves listed under Equipment combinations [➙ 12]).

●

With normally-open valves, "direct acting" means that with a signal input of 0 V, the valve

is open.
