2.7 Protection Devices
2.7.1 Torque
RTS Compact Linear actuators provide a electronic torque monitoring.
The switch off torque can be modied 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 specied with the order, the actuator is supplied from the factory with
the maximum congurable torque.
For more information, (see Section 7.2).
2.7.2 Motor Temperature
All RTS Compact Linear CL 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 12.1).
2.7.3 Input fuse, thermal fuse
The frequency inverter is protected by an input fuse and the explosion-proof
version also has a thermal fuse. If one of these fuses releases, a serious defect
accours and the frequency inverter will be disconnected permanent from the
power supply. Then the frequency inverter must be changed.
2.8 Ambient Temperature
Unless otherwise specied 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-specic components.
Please refer to the technical data sheets to conrm the as-delivered product specications.
