rack up to the stop and connected by the enclosed 6-wire ribbon cable
(6) to the motherboard (see figure 2-9, page 33).
The SIA module contains:
a digital output for outputting a group fault message (see alarm
S
module)
The floating digital output is implemented as a self error reporting
semiconductor output.
two digital outputs for reporting two mechanically adjustable limit
S
values (L1, L2) by slot initiators.
These two outputs are electrically independent of the rest of the
electronics.

The manometer block for single-acting actuator contains two
manometers which are screwed to the lateral pneumatic connection of
the positioner with O-rings. The values for the input pressure (supply
air PZ) and output pressure (actuating pressure Y1) are displayed.
The manometer block for double-acting actuators contains three
manometers which are screwed to the lateral pneumatic connection of
the positioner with O-rings. The values for the input pressure (supply
air PZ) and output pressure (actuating pressure Y1 and Y2) are
displayed.
