Operating instructions for actuators type AB

1 Introduction/Notes

These operating instructions apply to SCHIEBEL actuators of the AB series.
The scope of application covers the operation of industrial valves, e.g., globe valves, gate valves, butterfly
valves and ball valves. For other applications please consult with the factory.
The manufacturer shall not be liable for incorrect use and possible damage arising thereof. The risk shall be
borne solely by the user.
Using the unit as intended also entails the observance of these operating instructions!
When operating electrical equipment, certain parts inevitably carry hazardous voltage levels. Work
on the electrical system or equipment must be carried out only in accordance with electrical regulations by a
qualified electrician himself or by specially instructed personnel under the control and supervision of a qualified
electrician.
Maintenance instructions must be observed as otherwise the safe operation of the actuator cannot be guaran-
teed.
Failure to follow the warning information may result in serious bodily injury or property damage. Qualified
personnel must be thoroughly familiar with all warnings contained in this operating manual.
Proper transport, storage, installation, assembly and careful commissioning are essential to proper and safe
operation.
When working in potentially explosive areas, observe the European Standards EN 60079-14 "Elec-
trical Installations in Hazardous Areas" and EN 60079-17 "Inspection and Maintenance of Electrical
Installations in Hazardous Areas".
Maintenance work on open actuators may only be conducted if these are de-energized. Reconnec-
tion during maintenance is strictly prohibited.

1.1 Serial number and nameplater

Each actuator carries a serial number. The serial number is a 8-digit number that begins with the
year and that can be read from the nameplate (see Figure 1) of the actuator (the nameplate is located under
the hand lever).
Using this serial number, SCHIEBEL can uniquely identify the actuator (type, size, design, options, technical
data and test report).
Actuators which are suitable for operation in explosive atmosphere (see EU-Richtlinie 94/9/EG and
EN60079-0 Standard) are separately designated by a special model plate (EEx, TÜV-Standard Figure 2).
