Transport:
• Transport temperature -40°C to 70°C.
• Protect against external forces (shock, Vibration etc.).
• Do not damage the protective lacquer.
Installation site information:
The valve installation site should be easily accessible and provide sufficient room for service and removal of
actuators. Manual shut-off valves should be located up and downstream of the control valve, to facilitate
service and repairs without draining the piping system. The control valve should preferably be installed
vertically with the actuator installed in the upright position. When carrying out inclined to horizontal
installation of actuators the stanchions must be aligned vertically one above the other.
Pipelines should be insulated to protect actuators against high temperatures; here sufficient room is to be left
for servicing the stem seal pack. For trouble free function of the control valve the pipe immediately upstream
of the valve should be straight for the length of at least 2x DN and the pipe immediately downstream for the
length of at least 6x DN.
Actuator mounting-and removal information:
The control valve is normally supplied complete with actuator. It is not permitted to remove or replace an
actuator on systems in operation, under operating temperature and pressure. For conversion or service, the
actuator mounting procedure should follow the actuator SDI. During mounting procedure the plug should
NOT be rotated with downward pressure. Ensure adherence to max. valve operating forces for actuator
replacement.
Removal of Actuators:
In addition to the valid, general guidelines for installation and the TRB 700, the following point should be
observed:
• Pressure free pipe system
• Cooled fluid
• Drained pipe system
• With corrosive or aggressive fluids the pipe system should be vented.
• Work to be performed by qualified personnel only
Danger
Caution:
When laying electric wiring, regulations for setting up high-voltage systems must be
observed. Mains voltage and frequency must match with data on the ID plate.
The DA-30xx-761x Actuator has no on/off switch. Because of this, an isolation switch should
be installed in the supply line of the device.
Supply Voltage Connection:
Wire gauge min. 1 mm², max. 2.5 mm²
Electrical isolation System-Side:
Prior to the removal of the actuator cover, e.g. for mechanical maintenance and adjustment,
line voltage supply must be disconnected by means of an isolation switch, safeguarded
against inadvertent operation.
Danger
Electrical Connection:
• Lead cable through the cable adapter to the respective terminals, and then remove
insulation from wire tips. Inside the actuator, wires must be routed or fastened so that
they are protected against damage by moving or rotating parts and removal or
replacement of the actuator cover.
• Ground conductor should be secured on the ground conductor terminal (not in a 24V
apparatus).
• Tighten cable adapter to achieve a reliable strain relief
Fitting of accessories: ER 2 (ER 135)
Fitting and testing must be in accordance with accessory by-pack installation instructions.
Supply Voltage Fusing, System-Side:
max. 6A, 2A by 24V, DIN VDE 116 must be
observed!
