Start-Up - Samson 42-36 E Mounting And Operating Instructions

6 Start-up

The work described in this section is only to
be performed by personnel appropriately
qualified to carry out such tasks.
DANGER
!
Risk of fatal injury due to electric shock.
Î Upon installation of the electric cables,
you are required to observe the regula-
tions concerning low-voltage installations
according to DIN VDE 0100 as well as
the regulations of your local power sup-
plier.
Î Use a suitable voltage supply which
guarantees that no dangerous voltages
reach the device in normal operation or
in the event of a fault in the system or
any other system parts.
Î Only perform the electrical connection
after switching off the supply voltage.
Make sure the supply voltage cannot be
switched on again unintentionally.
DANGER
!
Risk of personal injury due to process me-
dium escaping.
Î Do not start up the regulator until all
parts have been mounted.
WARNING
!
Risk of personal injury due to pressurized
components and process medium being dis-
charged.
Î Do not loosen the control line while the
valve is pressurized.

WARNING
!
Risk of burn injuries due to hot or cold com-
ponents and pipeline.
Regulator components and the pipeline may
become very hot or cold. Risk of burn inju-
ries.
Î Allow components and pipelines to cool
down or warm up to the ambient tem-
perature.
Î Wear protective clothing and safety
gloves.
WARNING WARNING
! !
Crush hazard arising from moving parts.
The regulator contains moving parts (actua-
tor and plug stem), which can injure hands
or fingers if inserted into the valve.
Î Do not insert hands or finger into the
yoke while the valve is in operation.
Î Disconnect the supply voltage and pro-
tect it against unintentional reconnection
before performing any work on the con-
trol valve.
Î Do not impede the movement of the actu-
ator or plug stem by inserting objects in-
to their path.
Î Before unblocking the actuator and plug
stem after they have become blocked
(e.g. due to seizing up after remaining in
the same position for a long time), re-
lease any stored energy in the actuator
(e.g. spring compression). See associat-
ed actuator documentation.
Î Before starting any work on the regula-
tor, depressurize plant sections as well as
the regulator.
