1 Safety instructions and measures
Intended use
The Type 5827 Electric Actuator is designed to operate a mounted globe valve used in heat-
ing, ventilation and air-conditioning systems as well as in process engineering and industrial
energy transfer systems. The digital positioner ensures a predetermined assignment of the
valve position to the input signal.
The actuator is designed to operate under exactly defined conditions (e.g. thrust, travel).
Therefore, operators must ensure that the actuator is only used in operating conditions that
meet the specifications used for sizing the actuator at the ordering stage. In case operators
intend to use the actuator in applications or conditions other than those specified, contact
SAMSON.
SAMSON does not assume any liability for damage resulting from the failure to use the de-
vice for its intended purpose or for damage caused by external forces or any other external
factors.
Î Refer to the technical data for limits and fields of application as well as possible uses. See
the 'Design and principle of operation' section.
Reasonably foreseeable misuse
The actuator is not suitable for the following applications:
− Use outside the limits defined during sizing and by the technical data
− Outdoor use
Furthermore, the following activities do not comply with the intended use:
− Use of non-original spare parts
− Performing service and repair work not described
Qualifications of operating personnel
The actuator must be mounted, started up, serviced and repaired by fully trained and quali-
fied personnel only; the accepted industry codes and practices must be observed. According
to these mounting and operating instructions, trained personnel refers to individuals who are
able to judge the work they are assigned to and recognize possible hazards due to their spe-
cialized training, their knowledge and experience as well as their knowledge of the applica-
ble standards.
