RCE-SR
Electro-hydraulic actuators
INSTALLATION AND ADJUSTMENT
1. RCE230-240: Remove the plug 1/8" in the venting
hole nearest to the intermediate piece. Mount the
angular coupling and the indicator tube.
RCE250-280: Remove the transport plug fitted in
the oil refill hole. Screw on the filler cap included
in the shipment. Remove the plug 1/8" in the vent-
ing hole nearest to the intermediate piece. Mount
the angular coupling and the indicator tube.
Under very wet, windy or dusty conditions it is
advantageously to use a closed loop hydraulic
system. The closed loop system is achieved by
only connecting the indicator tube (pos.13 page
3) to the hydraulic tank and keeping the filling
plug mounted in the tank.
2. When the electrical connection has been
accomplished, check that:
a. The motor runs in the correct direction, see the
arrow on the cover.
b. The valve opens and closes correctly. The stem
key grip must be parallel with the centre line of
the piping for open position and in 90° to the
same in closed position (actuators mounted
alongside piping).
c. The limit switches are effected.
3. Vent the actuator with the aid of venting key
included in the shipment. The motor should be
running. If solenoid valves or speed restrictors are
supplied, they should be in position pressurising
the actuator
4. Check the oil level when the actuator is in spring
return position. The pump motor must be turned
off.
5. Make sure that there is no oil in the indicator tube
for piston leakage. The tube is emptied by loosing
the lower coupling.
6. Adjust the opening speed (only actuators in
modulating design) and the closing speed with the
aid of the speed restrictors.
7. Mount the protective cover, if supplied. Rod and
screws are supplied.
8. The emergency operation handwheel is locked
in neutral position (see instructions for each
model) with a chain or similar around a fixed
device (example: pipe line).
Valid for actuators with manual/emergency
override option only.
9. The seal on the pressure restriction valves must
not be broken.

MAINTENANCE INSTRUCTIONS
1. Check the oil level at least twice a year when
the pump motor is turned off and the actuator is in
spring return positions.
RCE230-240 are equipped with a level glass,
where the oil level is visible.
Other models: Check using the dip stick on the
filler cap that the oil level is between min. and
max. Note: The cap must be tightened. Avoid
overfilling. For normal operation conditions an oil
change is recommended once every second year.
Rinsing fluids must not be used, only hydraulic oil.
2. Check that there is no oil in the indicator tube for
piston leakage. The tube is emptied by loosen-
ing the lower coupling. If oil flows in the tube after
emptying, please contact the supplier.
3. If "noise" occurs:
a. Check the oil level.
b. Vent the actuator with a venting key.
4. Test run the unit regularly to prevent the valve
from sticking due to long stand still periods.
5. The unit is cleaned from oil spill and similar.
6. Keep the unit clean from snow and ice. Especially
"open-mounted" extra equipment.
7. Check the anti-corrosion treatment. Improve when
necessary.
8. Check tubes, hoses and cables. Exchange
damaged parts.
9. All manual operation must be carried out with
the actuator in pressureless condition. See further
instructions on page 2.
Valid for actuators with manual/emergency
override option only.
The hydraulic system is factory filled with hydraulic
fluid ExxonMobile Univis HVI 13.
Only use this or alternatively Aero Shell Fluid 4 or 41
Castrol Aero HF585B when refilling.
