11 Decommissioning
The work described in this section is only to
be performed by personnel appropriately
qualified to carry out such tasks.
Risk of fatal injury due to electric shock.
Î
Before disconnecting live wires, switch
off the supply voltage at the actuator and
protect it against unintentional reconnec
-
tion.
Risk of personal injury due to residual
process medium in the valve.
While working on the valve, residual me
-
dium can flow out of the valve and, depend
-
ing on its properties, cause personal injury,
e.g. (chemical) burns.
Î
Wear protective clothing, safety gloves
and eye protection.
Risk of burn injuries due to hot or cold
components and pipeline.
Valve components and the pipeline may be
-
come very hot or cold. Risk of burn injuries.
Î
Allow components and pipelines to cool
down or warm up to the ambient tem
-
perature.
Î
Wear protective clothing and safety
gloves.
To decommission the electric actuator for re-
pair work or disassembly, proceed as fol-
lows:
Î
Put the control valve out of operation (see
associated valve documentation).
Î
Disconnect the supply voltage and pro-
tect it against unintentional reconnection.
Î
Make sure that a signal from the control-
ler cannot act upon the actuator.
For versions with "actuator stem extends"
fail-safe action, the supply voltage must re
-
main connected to prevent the actuator stem
extending by itself.
