Safety instructions

DANGER
Danger to life due to falling or toppling loads.
Risk of death or serious injury due to the device falling down
or toppling over!
• Standing under suspended loads is prohibited.
• Do not detach the hoisting equipment until installation is
complete.
• Only use the dedicated load pick-up devices (eyebolts) for
suspending the components.
Please observe the following safety instructions
• Only qualified specialists may mount and adjust the control
actuator, and make the electrical connection.
• When working on the actuator or the electronics always
observe the locally valid accident prevention regulations and
the regulations concerning the construction of technical
installations.
• Switch off the supply voltage and take precautions to
prevent unintentional switch-on.

Mounting

Actuator check

Before you start to install the actuator make sure that the
delivery status corresponds to the ordered status and to the
intended use.
• Check the oil level when installing the device in positions
other than IMV 1. Add oil if necessary.
• Once the actuator is installed, fasten the vent valve in the
uppermost oil hole.
• Prior to commissioning the device, make sure that the motor
and the connection chambers are free of dirt, humidity and
corrosion.
• Make sure adequate actuator travel is provided for the valve
stroke.

Installation instructions

• Make sure that no process forces are exerted on the final
control element.
• Do not lift the actuator by the motor or handwheel.
• The load pick-up device (eyebolt) attached to the actuator
may only be loaded in the vertical direction. Only use the load
pick-up device to lift / lower the actuator (without final
control element mounted).
• Make sure that the actuator is accessible from all sides so
that convenient handwheel operation, electrical connection,
or exchange of assemblies is possible.
• Select the installation location such to avoid direct exposure
to rain, snow and other environmental influences.
• The control actuators can withstand vibration loadings in
accordance with EN 60068-2-6, Table C.2 to 150 Hz and max.
2 g.
• The substructure should be designed to be level and torsion-
resistant.
• When mounting the actuator close to heat sources use an
insulating layer or shielding.
• Make sure that the maximum ambient temperature is not up-
scaled. If required, provide a sunshield to protect against
direct sunlight.
• The maximum rated force of the actuator may not be
permanently exceeded. Occasionally and for short periods
only, loads of up to twice the rated force are permissible.
• The internal stops of the actuator are not tightly fastened
when delivered. During commissioning, the stops should be
adjusted in accordance with the description in Adaptation of
actuator stroke to the valve stroke (RSD, only) on page 13
and tightened.

Valve design requirements

• The force in the end position can be up to 2.5 times higher
than the rated force.
