1.2 Notes on possible personal injury
WARNING
!
Risk of personal injury due to incorrect operation, use or installation as a result of
information on the regulator being illegible.
Over time, markings, labels and nameplates on the regulator may become covered
with dirt or become illegible in some other way. As a result, hazards may go unno-
ticed and the necessary instructions not followed. There is a risk of personal injury.
Î Keep all relevant markings and inscriptions on the device in a constantly legible
state.
Î Immediately renew damaged, missing or incorrect nameplates or labels.
Risk of personal injury due to preloaded springs.
Regulators in combination with preloaded set point springs are under tension. These
regulators can be identified by the red warning label on the actuator's set point springs.
Î Before starting any work on the set point springs, relieve the compression from the
preloaded springs.
Î Only use the SAMSON disassembly tool (1280-4052).
Crush hazard arising from moving parts.
The regulator contains moving parts (actuator and plug stem), which can injure hands
or fingers if inserted into the valve.
Î Do not insert hands or fingers between the set point springs while the regulator is in
operation.
Î Before performing any work on the regulator, depressurize the plant. Disconnect or
shut off the external control line.
Risk of personal injury due to residual process medium in the regulator.
While working on the regulator, residual process medium can escape and, depending
on its properties, may lead to personal injury, e.g. (chemical) burns.
Î If possible, drain the process medium from all the plant sections affected and the
regulator.
Î Wear protective clothing, safety gloves and eye protection.
