2.3 Operating Mode
RTS Compact Multi-Turn CM actuators are suitable for open-loop control (S2 operating
mode - on/off duty) and closed-loop control (S9 operating mode - modulating duty)
according to EN 60034-1.
2.4 Protection Class
RTS Compact Multi-Turn CM actuators come by default with IP68 (EN 50629) protection.
CAUTION: PROTECTION CLASS AND CABLE GLANDS
The protection class specied on the type label is only effective when cable glands also
provide the required protection class, the cover of the connection compartment is carefully
secured and the mounting position (see Section 2.5) is observed.

General
User Instructions
MAN-02-04-60-0349-EN Rev. 3 February 2019
We recommend metallic threaded cable glands with a metrical thread. Unused, cable
inlets must be closed with stopping plugs. On explosion-proof actuators, cable glands with
protection class EEx e according EN60079-7 must be used. After removing covers for
assembly purposes or adjustment work, take special care upon reassembly so that seals are
not damaged and remain properly fastened. Improper assembly may lead to water ingress
and to failures of the actuator.
NOTE:
The cover of the control unit - the Operating unit - (see Figure 1) must not be opened.
Allow a certain sag in the connector cables before reaching the screwed cable glands so that
water can drip off from the connector cables without running to the screwed cable glands.
As a result, forces acting on the screwed cable glands are also reduced. (see Section 2.5)
Section 2: General
2.5 Mounting Position
Generally, the installation position is irrelevant. However, based on practical experience, it
is advisable to consider the following for outdoors use or in splash zones:
• Mount actuators with cable inlet facing downwards
• Ensure that sufcient cable slack is available

2.7 Protection Devices
2.7.1 Torque
RTS Compact Multi-Turn actuators provide 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 Multi-Turn CM 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 by a thermal fuse. If one of the fuses releases, a serious defect occurs and
the frequency inverter must be replaced.
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.
2.9 Delivery Condition of the Actuators
For each actuator, an inspection report is generated upon nal 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.
