5.6.2 Version for double-
acting actuator
A reversing amplifier must be additionally
mounted for applications with double-acting
(DAP) actuators or applications with sin-
gle-acting (SAP) actuators that include par-
tial stroke testing.
In this case, a special adapter bracket (4) is
required for mounting.
