Form-Fit Attachment; Installing The Control Valve Into The Pipeline; Electrical Connections - Samson TROVIS 5724-3 Mounting And Operating Instructions

Mounting and start-up
5.1.2

Form-fit attachment

1. Place the actuator on the yoke (15) and
tighten the coupling nut (4) (tightening
torque 20 Nm).
2. Place actuator with yoke (15) on the
valve and tighten the nut (17) (min. tight-
ening torque 150 Nm).
3. Pull plug stem until it reaches the actua-
tor stem or extend actuator stem using
the handwheel (2).
4. Position the clamps of the stem connector
(16) included in the accessories on the
ends of the actuator stem and plug stem
and screw tight.
5.2 Installing the control valve
into the pipeline
NOTICE
!
Degree of protection not achieved due to in-
correct mounting position.
Do not install the valve with the actuator
suspended downwards (see Fig. 5).
Î Install the valve into the pipeline accord-
ing the specifications in the mounting
and operating instructions of the valve.

5.3 Electrical connections

DANGER
!
Risk of electric shock.
− Upon installation of the electric cables, you
are required to observe the regulations
concerning low-voltage installations ac-
22
cording to DIN VDE 0100 as well as the
regulations of your local power supplier.
− Use a suitable power supply which guar-
antees 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.
− Connect the actuator to the electrical net-
work only after the power supply is first
switched off. Make sure the power cannot
be switched on unintentionally.
− The switching output L' may be live. Do not
touch the switching output L'.
The electric actuator requires a fast-response
Pt 1000 sensor to be connected for it to func-
tion.
Two set points W1 and W2 can be used.
The binary input BI1 is used to switch be-
tween the set points.
In addition, a water flow sensor or a flow
switch can be connected to quickly recognize
when hot water is being tapped.
Alternatively, instead of the Pt 1000 sensor,
the current input 0/4 to 20 mA can be used
for control purposes in mechanical engineer-
ing applications.
The connected temperature sensor and the
current input configured as 4 to 20 mA are
monitored for line breakages.
A wire breakage of a sensor is indicated by
the red LED blinking slowly. It cannot be de-
tected when a 0 to 20 mA input signal is
used.
