3.8 Adjusting of stop ends (Fig.8)
Mechanical stop ends is possible to adjust in scale from –5 °C to 10 °C for each position
dependently. Electric
actuator is by producer
adjusted to operating
angle according to the
specification.
While setting, adjusting
and resetting stop ends
follow next steps:
•
loosen the counter
nut of specific stop
end
•
set the stop end to
the new position
•
lock the stop end
screw with the
counter nut
•
adjust the electric
end position for
switch S3 or S4 as
is significated in
article 3.5.
Attention!
Operating angle adjusted by stop ends must be greater than angle set electronically to the
actuator. The stop ends are used only for position setting by manual adjusting of the actuator. Use the
stop ends in motor-operated operation of actuator is
inadmissible!
4. Service, maintenance and troubleshooting
4.1 Service
1. In general it is provided that service of the EA is performed by a qualified worker in accordance with
requirement given in Chapter 1!
2. After putting the EA into operation it is needed to verify whether during manipulation any scratch on
surface occurred, it is to be removed to prevent actuator against corrosion!
The EA SP/SPR requires just negligible service. Proper putting into operation is a recondition of
reliable operation.
The service of the EA leads from the operation conditions and usually resides in information
processing for further arranging of required functions.
The stuff has to perform prescribed maintenance to prevent the EA during operation against
impacts of environment, which exceed the frame of allowed influences.
While mains failure the actuator stops in the position where it was before the failure. If needed
the actuator can be reset with the handwheel.
