89/336 EEC EC Directive on Electromagnetic
Compatibility
Modifications to the actuator which have an
effect on the technical data given in this instruc-
tion manual and its intended use, i.e. signi-
ficantly alter the actuator, render this
manufacturer‘s declaration null and void.
3. Intended Use
When mounted on a valve and connected to a
system control, the purpose of this actuator is to
ł actuate valves with 90° pivoting (ball valves and
butterfly valves),
ł indicate the previously calibrated end positions
of the valve via electrical signal to the system
control (accessory), and
ł provided that the actuator data corresponds to
the electrical control and the valve and
ł in case of interruption in the supply voltage,
warrant that the actuator/valve remains in the
current position. Please use emergency manual
override or install fail-safe return.
The actuator is not intended for uses other than
those listed here. If the instructions contained in this
manual are not observed, the manufacturer is
excluded from all liability for the above mentioned
products.
