.
Connect cables according to order related wiring diagram ACP . . . . The
wiring diagram applicable to the actuator is attached to the handwheel in
a weather-proof bag, together with the operation instructions. In case the
wiring diagram is not available, it can be obtained from AUMA (state
commission no., refer to name plate) or downloaded directly from the
Internet (see page 67).
A special parking frame for protection against touching the bare contacts
and against environmental influences is available (see address list page 68).
9.2
Heater
AUMA part-turn actuators have a heater installed as standard. Unless
ordered otherwise, the heater is internally supplied.
9.3
Motor protection
In order to protect the motor against overheating a thermoswitch is
embedded in the motor windings. The controls AUMATIC switch off the
motor as soon as the max. permissible windings temperature is reached.
The switch is connected again automatically after the motor has cooled
down to a temperature of approx. 90 °C Afterwards the actuator can be
switched on again.
9.4
Remote position transmitter
For the connection of position transmitters (potentiometer, RWG) screened
cables must be used.
9.5
Subsequent mounting of the controls
To avoid malfunctions we recommend that in case of
subsequent mounting of the AUMATIC on the actuator the
electrical interfaces are checked for compatibility.
9.6
Type of seating
The limitation of travel is realised via limit switches in both end positions.
A torque sensor is not available.
A torque seating is not permissible. The set type of seating
can be checked via the parameters "
OPEN POSITION
" and
"
CLOSED POSITION
" (page 27).
For further information regarding the type of seating see also page 55,
subclause 16.9.
9.7
Fitting of the cover
.
After completion of the power supply connection, insert the socket carrier
(26.2), see figure C2, page 11, into the plug cover (26.0) and fasten it with
screws (26.2.5).
.
Clean sealing faces at plug cover (26.0) and check whether O-ring is in
good condition. Apply a thin film of non-acidic grease (e.g. Vaseline) to the
sealing faces.
.
Replace plug cover (26.0) and fasten 4 bolts (26.01) evenly crosswise.
