· 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» on page 3)
· With normally-open valves, «direct-acting» means that with a signal input of 0 V, the
valve is open.

The rotary switches LO and UP can be used
to apply an upper and lower limit to the stroke
in increments of 3%, up to a maximum of 45%
The rotary switches LO and UP can be used
to determine the starting point or the operating
range of a sequence.
