1.1 Application
The linear actuator operate the final control
element which require a linear travel motion
from 15 to 120 mm and a po itioning force in
the range of 2 to 25 kN.
The hut-off force of the actuator i adju ted
permanently. The travel, however, can be
modified at a later date.
1.2 Versions
The electrical component are located epa-
rately from the gear underneath the ealed
cover where they are protected from du t and
can be ea ily acce ed when the cover i
removed.
The basic version of the device compri e :
–Two torque
witche DE-S1
and
DE-S2
.
They witch off the motor when the force ad-
ju ted in the actuator i counterbalanced by
a corre ponding force. Thu , they protect
the final control element from damage, and
the actuator from overload.
–One travel
witch WE-S3
for limitation of
the travel in the opening direction.
–Two travel
witche WE-S4
and
WE-S5
for
indicating intermediate and po ition of the
final control element.
The following component can be in talled
optionally:
– A fourth travel
witch WE-S6
for indicating
certain control element po ition .
– One or two
potentiometer
or one
electronic
po ition tran mitter ESR
for analog remote
tran mi ion of the final control element’
po ition.
–One
heating re i tor
to prevent the forma-
tion of conden ation water underneath the
cover when the humidity i high and the am-
bient temperature fluctuate con iderably.
At an in ide temperature of >60 °C, the
heating re i tor deactivate the heating via
a temperature relay; it reactivate the heat-
ing at a temperature of <40 °C.
– One electronic po itioner for the analog
control 0 (2) to 10 V / 0 (4) to 20 mA (only
for 230 V, 50 Hz AC motor ).
1.3 Function
The rotary motion of the motor i tran ferred
to the gear wheel with a female thread via the
gearing.
The pi ton rod with the matching male thread
engage the female thread. An anti-rotation
device ecure the rod and prevent it from ro-
tating.
The pi ton rod perform a linear motion,
either pulling or pu hing, when the female
threaded gear wheel i turned via the motor
gear.

4Installation
4.1 Installation requirements
Prior to in tallation, make ure that the follow-
ing requirement are met:
– Proper voltage and control ignal re-
quired to operate the actuator are avail-
able.
– Electrical line are de-energized.
– Pipeline are depre urized and cold.
Choo e the attachment po ition of the linear
actuator o a to en ure the following:
– The actuator can be ea ily acce ed.
– There i ufficient pace to remove the cover
( ee "3 Dimen ion ").
– The actuator i protected again t exce ive
heat radiation.
– The ambient temperature i in the range
from -20 to +60 °C.
If in talled outdoor , the actuator mu t be pro-
tected with an additional cover, e.g. again t
humidity (rain, now), heat (direct unlight),
cold (fro t), exce ive draft, du t, etc.
When ambient temperature are ubjected to
trong fluctuation and if the humidity i high,
we recommend in talling a heating re i tor to
minimize the formation of conden ate in the
hou ing ( ee "8.1 Heating").
If in talled in an environment with a high pol-
lutant concentration, (e.g. in area with a high
traffic volume, indu trial area , near coa tal
region ), the external actuator part mu t be
made of non-corro ive material and be
coated with a pecial fini h.
4.2 Mounting position
The mounting po ition i arbitrary, however,
the linear actuator mu t not be vertically u -
pended.
When mounted with the actuator tem in hori-
zontal po ition, the yoke mu t be mounted
uch that it two rod are po itioned vertically
one on top of the other.
4.3 Attaching the actuator to a
control valve
On delivery, the actuator tem i extended to
the lower final po ition.
Prior to a embly, check the following:
– Doe the technical data of the linear actua-
tor match the application requirement ?
– I the valve complete (yoke on the actuator
or on the valve)?
– Are the coupling part aligned?
– I the linear actuator ready - with ring nut
and coupling part for attachment to the
valve?

^clamp 1 L = ^clamp 2
The actuator tem retract into the actuator
and move to "OP N" po ition (open ).
Three-phase a.c. drive motors
External rever ing contactor hould be u ed.
L1=
^ clamp 1;L2= ^clamp 2;L3= ^clamp 3
Switch on the upply voltage, thu i uing the
hort-term command "OPEN/CLOSED" .
– Check, whether the actuator tem move in
the right direction.
– If the actuator tem doe not move in the
right direction, witch motor connection 2
and 3, and repeat te t.

WARNING!
The actuator mu t only be adju ted
electrically or manually within the
given travel.
If you adju t the travel to a value ex-
ceeding the given value , the actuator
may be damaged!
