Certification
Canadian Radio Interference-Causing Equipment Regulation, IECS-003, Class A:
4 English

Supporting test records reside with the manufacturer.
This Class A digital apparatus meets all requirements of the Canadian Interference-Causing
Equipment Regulations.
Cet appareil numérique de classe A répond à toutes les exigences de la réglementation canadienne
sur les équipements provoquant des interférences.
FCC Part 15, Class "A" Limits
Supporting test records reside with the manufacturer. The device complies with Part 15 of the FCC
Rules. Operation is subject to the following conditions:
1. The equipment may not cause harmful interference.
2. The equipment must accept any interference received, including interference that may cause
undesired operation.
Changes or modifications to this equipment not expressly approved by the party responsible for
compliance could void the user's authority to operate the equipment. This equipment has been tested
and found to comply with the limits for a Class A digital device, pursuant to Part 15 of the FCC rules.
These limits are designed to provide reasonable protection against harmful interference when the
equipment is operated in a commercial environment. This equipment generates, uses and can
radiate radio frequency energy and, if not installed and used in accordance with the instruction
manual, may cause harmful interference to radio communications. Operation of this equipment in a
residential area is likely to cause harmful interference, in which case the user will be required to
correct the interference at their expense. The following techniques can be used to reduce
interference problems:
1. Disconnect the equipment from its power source to verify that it is or is not the source of the
interference.
2. If the equipment is connected to the same outlet as the device experiencing interference, connect
the equipment to a different outlet.
3. Move the equipment away from the device receiving the interference.
4. Reposition the receiving antenna for the device receiving the interference.
5. Try combinations of the above.
Product overview
N O T I C E
The use of a Real-Time Controller (RTC) module does not replace system maintenance. Make sure that all
instruments connected to the RTC open/closed-loop controller are always in good condition. Regular
maintenance is necessary to make sure that the instruments supply correct, reliable measurement values. Refer
to the user documentation of each instrument.
RTC modules are general application control units that makes some processes better in treatment
plants. RTC modules are available as 1-channel, 2-channel or multi-channel systems.
Multi-channel RTC modules are usually operated on industrial PCs (IPC) and all input/output signals
are transferred through the sc1000 controller. Refer to the sc1000 documentation. Refer to the
documentation supplied with the hardware.
Product components
N O T I C E
The combination of pre-assembled components supplied by the manufacturer does not show an independently-
functioning unit. In accordance with EU guidelines, this combination of pre-assembled components is not supplied
with a CE mark, and there is no EU declaration of conformity for the combination. However, the conformity of the
combination of components with the guidelines can be proved through technical measurements.
Make sure that all components have been received. If any items are missing or damaged, contact the
manufacturer or a sales representative immediately.
Each RTC module is supplied with a:
• SUB-D connector (9 pin)
English 5

• Ferrite core (foldable)
All components shown in Figure 1 are pre-wired. Figure 2 shows an analog and digital input/output
module.

Installation
WARNING
Potential Electrocution Hazard. Only qualified personnel should conduct the tasks described in this
section of the manual.
CAUTION
Possible danger to sensor or logger. Always disconnect power to the instrument when making any
electrical connections.
Install the RTC module
Only install RTC DIN rail versions on a DIN rail. Only install an IPC panel mount versions according
to the IPC manufacturer specifications that are supplied with the hardware.
Attach the module horizontally. Make sure that the passive aeration element operates correctly.
Make sure that there is a minimum of 30 mm (1.2 in.) of space around the module.
To use the RTC module indoors, install the module in a control cabinet. To use the RTC module
outdoors, install the module in an enclosure. Refer to Specifications on page 3 for the enclosure
specifications.
An sc1000 controller is necessary to operate the RTC module. Refer to the sc1000 controller
documentation. It is necessary to use software version V2.30 (or higher) for the sc1000 controller.
Hardware is subject to change without notice. Refer to the sc1000 documentation and other
hardware documentation for input/output electrical wiring. Additional information of RTC controllers
and setting parameters is available on the manufacturer's website.
This instrument is rated for an altitude of 2000 m (6562 ft) maximum. Use of this instrument at an
altitude higher than 2000 m can slightly increase the potential for the electrical insulation to break
down, which can result in an electric shock hazard. The manufacturer recommends that users with
concerns contact technical support.
Supply power to the RTC module
D A N G E R
Electrocution hazard. Do not connect AC power directly to a DC powered instrument.
An external deactivation switch is necessary for all installations. Refer to Table 1.
Table 1 Supply voltage of the RTC module
Specification Description
Voltage 24 V DC (-15%/+20%), maximal 25 W
Recommended fuse C2
With 110–240 V option 240 V, 50–60 Hz, approximately 25 VA
Connect to the process instruments
The measurement signals of the sc sensors are supplied to the RTC module through the RTC
communication card in the sc1000. For information about the power supply of the sc1000 controller
and the sc sensors, refer to the applicable documentation for the sc1000 controller and sc sensors.
English 7

Connect to the controller
Attach the supplied SUB-D connector to a two-wire, shielded data cable (signal or bus cable). Refer
to the applicable documentation for the data cable connection.
Connect to the automation unit
Different versions of RTC modules are installed with other components that can connect to the
automation unit of the plant.
