Type 8692, 8693
Ensure that the pneumatic connections of Type 8692/8693
and those of the valve actuator are situated preferably verti-
cally one above the other (see "Fig. 11").
NOTE!
To comply with the degree of protection IP65 / IP67, do not
fasten the fastening screws too tightly.
▶ Maximum tightening torque: 1.5 Nm.
→
Attach Type 8692/8693 to the actuator using the two side fas-
tening screws. In doing so, tighten the screws only hand-tight
(max. tightening torque: 1.5 Nm).

Observe the pneumatic connection that matches the desired
control function. See "Tab. 2: Pneumatic connection to actuator".
→
Establish the pneumatic connection between Type 8692/8693
and the actuator.
NOTE!
Damage or malfunction due to ingress of dirt and moisture!
▶ To comply with the degree of protection IP65 / IP67, connect the
pilot air outlet which is not required to the free pilot air port of the
actuator or seal with a plug.
"In rest position" means that the pilot valves of Type 8692/
8693 are isolated or not actuated.
If the ambient air is humid, a hose can be connected between
pilot air outlet 2 of the positioner / process controller and the
2
unconnected pilot air port of the actuator for control function
A or control function B.
As a result, the spring chamber of the actuator is supplied with
dry air from the vent duct of Type 8692/8693.
