Cautions
•
24Vac devices must be supplied by a transformer conforming to
EN 60742.
•
Observe installation instructions on page 5.
•
Observe wiring precautions on page 7.
•
Do not apply power unless the actuator is fitted to a valve.
•
Do not switch on power supply until commissioning checks have
been completed - see page 7.
•
Ensure wires are not inadvertently crossed over. Wiring errors not
only cause malfunctions; they may also damage controllers and/or
actuators.
•
Steam Applications: Following a shutdown of the steam system it is
important that the control valve is fully open before introducing
steam into the pipeline (purging) or damage may occur to the
actuator spindle or valve plug.
•
Observe maximum and minimum ambient temperatures.
•
Check thrust requirements and maximum differential of pressure of
valve to be driven. Do not exceed rated output thrust.
•
Interference with those parts under sealed covers renders the
guarantee void.
•
Design and performance of Satchwell equipment are subject to
continual improvement and therefore liable to alteration without
notice.
•
Information is given for guidance only and Satchwell do not accept
responsibility for the selection and installation of its products unless
information has been given by the company in wiring relating to a
specific application.
