of electric power the unit re-
quires.
Make sure the direction of rota-
tion of the actuator agrees with
the direction of rotation of the
valve. To make sure the direc-
tions of rotation agree, check
them in manual operation.

of voltage are given on the
unit’s typeplate.
The unit has been designed for auto-

manual operation.
Emergency manual opera-

DANGER
When working on pipelines, very
serious injuries or death can be
caused by burns, high pressure
in the system, or poisoning.
➢ Make sure there are no hot
or hazardous media on the
unit or in the pipelines.
➢ Make sure the unit is dis-
connected from all electrical
power supplies.
➢ Make sure the plant is
switched off and secured
against unauthorised
switching back on.
➢ Make sure the unit and
valve, including pipelines,
have cooled so that they are
no more than hand warm.
➢ Wear suitable protective
clothing and, when neces-
sary use suitable protective
equipment.
It is possible to operate manually the
shaft of the actuator, to open or close
the attached valve with the aid of a
hand lever (which can be ordered op-
tionally). To do this, carry out the fol-
lowing steps:
➢ Place the correct lever on the oper-
ating shaft.
Press the operating shaft into the
unit, i.e. in the direction of the arrow
in the figure.
The operating shaft must remain
pressed down during the entire manual
operation.
