Operation; Adjusting The Temperature Set Point - Samson EB 2111 Translation Of Original Instructions

7 Operation

Immediately after completing start-up or
placing the regulator back into service (see
the 'Start-up' section), the regulator is ready
for use.
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
!
Risk of personal injury due to pressurized
components and process medium being dis-
charged.
Incorrect opening of pressure equipment or
mounting parts may lead to the process me-
dium escaping to the atmosphere.
Î Do not loosen the control thermostat
while the valve is pressurized.
Î Do not start up the regulator until all
parts have been mounted.

WARNING
!
Risk of hearing loss or deafness due to loud
noise.
Noise emission (e.g. cavitation) may occur
during operation caused by the process me-
dium and the operating conditions.
Î Wear hearing protection when working
near the valve. Follow the instructions
given by the plant operator.
7.1 Adjusting the temperature
set point
Adjust the required set point by turning the
set point adjuster with the key (12.1) by
hand.
1. Slowly open the hand-operated shut-off
valve downstream of the valve and then
the shut-off valve upstream of the valve.
2. Adjust the set point at set point dial (13)
using the set point adjuster (12.2).
Set point adjuster
Î Turn the key (12.1) clockwise () to in-
crease the temperature set point.
Î Turn the key (12.1) counterclockwise ()
to reduce the temperature set point.
3. Monitor the temperature at the thermom-
eter (4) installed on the downstream side
on site.
