It is vital that the mounting kit used to connect the electric actuator to the component (ex: valve) is
correctly manufactured and assembled. The mounting bracket’s holes must be drilled to ensure that
the centerline of the actuator’s drive is perfectly in line with the component’s drive-centerline, and
that the drive coupling/ adaptor rotates around this centerline. The mounting holes of the actuator
conform to ISO 5211, and the female output drive conforms to DIN 3337.
We strongly recommend that valves/components to be actuated that have ISO 5211 compliant top
works are used wherever possible as it greatly assists in ensuring the concentricity of mounting the
actuator to the valve.
The male square end of the drive coupling MUST NOT be longer than the maximum depth of the
actuator female output drive when the assembly is bolted together.
Failure to comply with these instructions will cause uneven wear and dramatically reduce the
working life of the valve and actuator.
In case of a power supply failure, the actuator would stop in the position it were at this moment.
When the power supply is reestablished, the actuator would keep on working following the prior
direction.
VERY IMPORTANT:
Check that any object are blocking the valve (damper, etc.). Connect the actuator, following the
connection diagram on the label of the actuator. We recommend that the actuator has an independent
system of fuses, which could protect the actuator against other electrical devices.
