Ambient Temperature

Unless otherwise specified upon ordering, the following operating temperatures apply:
• On/off duty (open-loop control) -25 to +60°C
• Modulating duty (closed-loop control) -25 to +60°C
• Explosion-proof version -20 to +40°C (acc. EN60079-0)
• Explosion-proof version with extended temperature range -40 to +60°C
CAUTION: OBSERVE OPERATING TEMPERATURE
The maximum operating temperature can also depend on further order-specific components.
Please refer to the technical data sheets to confirm the as-delivered product specifications.

Delivery Condition of the Actuators

For each actuator, an inspection report is generated upon final inspection. In particular, this
comprises a full visual inspection, calibration of the torque measurement in connection
with an extensive run examination and a functional test of the microcontroller.
These inspections are conducted and documented according to the quality system and can
be made available if necessary. The basic setting of the end position must be performed
after assembly on the actuator.
General Information
Torque
RTS Fail-Safe Linear FL actuators provide electronic torque monitoring.
The switch off torque can be modified in the menu of the controller for each
direction separately. By default, switch off torque is set to the ordered value. If no
torque was specified with the order, the actuator is supplied from the factory with
the maximum configurable torque.
For more information, (see Section 8.2).
Motor Temperature
All RTS Fail-Safe Linear FL actuators are normally equipped with motor winding
temperature sensors, which protect the motor against excessive winding
temperature.
The display will show the corresponding error upon exceeding the permissible
motor temperature (see Section 3.1).
Input fuse, thermal fuse
The frequency inverter is protected by an input fuse and the explosion proof
version by a thermal fuse. If one of the fuses releases, a serious defect occurs and
the frequency inverter must be replaced.
