5 Mounting and assembly
The work described in this section is only to
be performed by personnel qualied for the
assignment accordingly.
Risk of fatal injury due to the ignition of an
explosive atmosphere.
Incorrect installation, operation or servicing
of the electropneumatic actuator in poten-
tially explosive atmospheres may lead to ig-
nition of the atmosphere and cause death.
Î The following regulations apply to instal-
lation in hazardous areas: EN60079-14
(VDE0165, Part1).
Î Work must only performed by personnel
who has undergone special training or
instructions or who is authorized to work
on explosion-protected devices in haz-
ardous areas.
5.1 Preparation for mounting
Before mounting, make sure the following
conditions are met:
− The actuator is not damaged.
− The type designation, material and tem-
perature range of the actuator match the
ambient conditions (temperatures etc.).
See the 'Markings on the device' section
for nameplate details.
Proceed as follows:
Î Lay out the necessary material and tools
to have them ready during mounting.
Î Check that the vent plugs to be used are
not blocked.
Î Check any pressure gauges mounted on
valve accessories to make sure they func-
tion properly.
Î When the valve and actuator are al-
ready assembled, check the tightening
torques of the bolted joints (uAB0100).
Components may loosen during trans-
port.
5.2 Mounting the device
Depending on the version, SAMSON control
valves are either delivered with the actuator
already mounted on the valve or the valve
and actuator are delivered separately. When
delivered separately, the valve and actuator
must be assembled together on site. Proceed
as follows to mount the actuator and before
start-up.
Risk of personal injury due to exhaust air
being vented.
The actuator is operated with air. As a result,
air is vented during operation.
Î During mounting make sure that vent
holes are not located at eye level in the
work position of the control valve and the
actuator does not vent at eye level in the
work position.
Î Wear eye and hearing protection when
working near the actuator.
