2.2 Serial Number and Type Label
Each actuator of the RTS Compact Linear CL series carries a serial number. The serial
number is a 10-digit number that begins with the year and that can be read from the type
label (see Figure 3) of the actuator (the type label is located next to the handwheel – see
Figure 4).
Using this serial number, Emerson can uniquely identify the actuator (type, size, design,
options, technical data and test report).

2.4 Protection Class
RTS Compact Linear CL actuators come by default with IP 68 (EN 50629) protection.
CAUTION: PROTECTION CLASS AND CABLE GLANDS
The protection class specied on the type label is only effective when cable glands also pro-
vide the required protection class, the cover of the connection compartment is carefully
screwed and the mounting position (see Section 2.5) is observed.
We recommend metallic screwed cable glands with a metrical thread. Furthermore, cable
inlets not be needed must be closed with screw 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 entrances 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)
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 sufcient cable slack is available

2.7 Protection Devices
2.7.1 Torque
RTS Compact Linear actuators provide a electronic torque monitoring.
The switch off torque can be modied 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 specied with the order, the actuator is supplied from the factory with
the maximum congurable 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 specied 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-specic components.
Please refer to the technical data sheets to conrm the as-delivered product specications.

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 micro controllers.
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.
CAUTION: OBSERVE COMMISSIONING INSTRUCTIONS
Commissioning instructions (see Section 5) must be strictly observed. During assembly
of the supplied valves at the factory, end postions are set and documented by attaching a
label (see Figure 7). During commissioning at the plant, these settings must be veried.
2.10 Information Notice (Tag)
Each actuator is provided with a bilingual tag containing key information, which is attached
to the handwheel after nal inspection. This tag also shows the internal commission
registration number (see Figure 7).

Section 4: Assembly and Disassembly of
Linear Units on Valves
In the following two subsections, the procedures for assembly and disassembly of linear
units on valves are explained step by step.
4.1 Security and Assembly Instructions
CAUTION
The device should be mounted and commissioned by qualied personnel. These are
individuals who are familiar and trained on the product line on how to operate and
assemble / disassemble the device.
Before assembling or disassembling the linear unit, the pipes have to be pressurized.
Only in the retracted state of the linear unit is an end stop available - if the maximum stroke
is exceeded in the extended state, the spindle moves out of its guidance! Do not move
against the end stop in electrical operation! The end limits of the actuator must be
set accordingly.
Never bring the valve cone with excessive force in the CLOSED position. This can damage
the high-quality sealing edges.
NOTE:
Installation work on any kind of actuator may only be performed by qualied personnel.
