Aligning The Travel Indication Scale; Mounting The Actuator - Samson TROVIS 5724-8 Mounting And Operating Instructions

Installation
5.3 Aligning the travel indica-
tion scale
The travel indication scale has two opposed
scales. Which scale is to be used depends
on the valve version. In the delivered state,
the scale alignment applies to globe valves
and three-way diverting valves. The align-
ment needs to be changed when a three-
way mixing valve is used.

verting valves (delivered state)

NOTICE
!
The display does not work due to an inter-
rupted cable connection.
Î Only open the front housing cover to
perform actions described in these in-
structions.
Î Do not disconnect the connecting cable
between the electric actuator and hous-
ing cover.
Tip
We recommend screwing the bottom screws
of the open housing front cover into the top
holes of the housing.
Î Remove scale, turn it and replace it so
that the pin is positioned over the appro-
priate hole (6, 12 or 15) corresponding
to the rated travel (6, 1 or 15 mm travel).
Î Close front cover.

5.4 Mounting the actuator

The electric actuator with process controller
is mounted either directly onto the valve or
using a yoke depending on the valve version
used (see Fig. 5-3).
NOTICE
!
Risk of actuator damage due to excessively
high tightening torques.
Î Observe the tightening torque.
