Warnings and Safety Precautions
Warnings and Safety Precautions
The Combics CAIXS2 indicator complies with the European Council Directives
as well as international regulations and standards for electrical equipment,
electromagnetic compatibility, and the stipulated safety requirements. Improper use
or handling, however, can result in damage and/or injury.
tRead these operating instructions carefully before use.
This will prevent damage to the equipment.
Please observe safety instructions 65015-750-16 in the safety information
section.
Please also bear the following points in mind:
3Make absolutely sure to unplug the indicator from the power before you connect or
disconnect any electronic peripheral devices to or from the interface port.
3If you use electrical equipment in installations and under ambient conditions
requiring higher safety standards, you must comply with the provisions as specified
in the applicable regulations for installation in your country.
3The operator shall be responsible for any modifications to the equipment and for
any connections of cables or equipment not supplied by Sartorius and must check
and, if necessary, correct these modifications and connections.
Warning when using RS-232 cables, purchased from other manufacturers:
These often have incorrect pin assignments for use with Sartorius equipment.
Connect only Sartorius accessories and options, since these are optimally designed
for use with your device. Therefore, do not use any proprietary solutions. The
operator shall be solely responsible for installation and testing of any modifications
to Sartorius equipment, including connection of cables or equipment not supplied
by Sartorius. Information on operational quality (in line with norms pertaining to
immunity) is available on request.
3Clean your equipment only as directed in the cleaning instructions (see “Care and
Maintenance").
3The display value can be affected by extreme electromagnetic influences. Once the
disturbance has ceased, the instrument can be used again in accordance with its
intended purpose.
Information on operational quality is available upon request from Sartorius (in line
with norms pertaining to immunity).
tIf you have any problems with your device, contact your local Sartorius office,
dealer or service center.
IP Protection
IP Rating
– The model meets the requirements of protection class IP69K.
–The IP65/IP69k protection rating is ensured only if the rubber gasket is
installed and all connections are fastened securely (including the caps on
unused sockets). Weighing platforms must be installed and tested by a certified
technician.

8 Operating Instructions Combics CAIXS2
Getting Started
Getting Started
1.) Connect weighing platform to the indicator.
2.) CAIXS2 Indicators have an intrinsically safe data interface which can be
connected to a computer (or any other peripheral device) using a barrier
(e.g. YDI05-Z).
3.) Connect the AC adapter.
4.) Configure the analog/digital converter (ADC).
5.) Carry out an alignment: Adjustment.
Connecting Weighing Platforms
You can connect any intrinsically safe, analog Sartorius platform to your CAIXS2
Indicator. Refer also to the Verification of Intrinsic Safety, the EC Type Examination
Certificate for the CAIXS2 and the load cell or analog weighing platform to be
connected.
3The load cell should be connected by a certified technician who has received
specialized training from Sartorius. Any installation work that does not conform
to the instructions in this manual results in forfeiture of all claims under the
manufacturer’s warranty.
3Make sure the CAIXS2 is disconnected from the power before starting any
connection work.
tSet up the weighing platform (see operating instructions for the weighing
platform).
tPlace the cable from the weighing platform next to the indicator.
tOpen the Combics indicator:
Loosen the ten cap nuts on the front panel. Remove the front panel.
t Remove the cover plate by removing the 4 screws.
Connection terminals are now visible.
Installing Connection and Interface Cables
3 The cable gland (IP69K protection) is pre-mounted on the indicator.
Please use extreme caution when performing any work on the equipment that
affects this cable gland.
You must use a torque wrench. The torque for this cable gland is 5 Nm.

Operating Instructions Combics CAIXS2 9
Getting Started
Preparing the Cable
tStrip approx. 14 cm from the end of the cable.
tShorten the shielding to approx. 2 cm and pull back over the insulation.
tStrip approximately 5 mm of the insulation from the wires of the connecting
cable and affix ferrules to the wire ends.
Attaching the Cable Entry
Please use extreme caution when performing any work on the equipment that
affects this cable gland.
You must use a torque wrench.
The torque for this cable gland is 5 Nm.

15
tRemove the protective caps from the bore hole on the indicator.
tInsert the included cable gland through the bore hole and secure from the
inside using the locknut (1).
tInsert the cable through the cable gland until the shielding (2) comes into
contact with the clamps (3). Tighten the screw-down nut (4) until the gasket
(5) inserted between the screw-down nut and cable forms a small beaded rim.
tCheck the shielding and clamps.
tSecurely connect the wires of the connecting cable in accordance with the
terminal assignments.
Connecting the Cable to the Analog/Digital Converter (ADC)
tInsert all cable wires through the ferrite case, wind them around the ferrite case
and then reinsert back through the ferrite case.
tScrew the wires tightly into the clamps.
Pin Assignment
tRefer to the data sheet or operating instructions of the weighing platform for
details on the assignment of wire colors/signals. Ensure any lines that are not
assigned are insulated correctly.
Connect weighing platform to ADU, Option A15
1 EXC+ blue
2 Sense+ green
3 OUT+ white
4 OUT- red
5 Sense- gray
6 EXC- black
tWhen connecting a load receptor that uses 4-conductor technology (the cable
of the weighing platform to be connected only has 4 lines), connect clamp
pairs 1 and 2 (EXC+ and SENSE+), and 5 and 6 (SENSE- and EXC-) with a wire
jumper.

Getting Started
tInsert the cover plate and tighten the screws.
tRe-attach the front panel and tighten the ten cap nuts with a torque of 1 Nm.
Connecting the Device to AC Power
Power is supplied via an external power supply device, which is provided with the
equipment.
3
The power connection must be made in accordance with the regulations applicable
in your country.
Make sure that the voltage rating printed on the manufacturer's ID label is identical
to that of your local mains voltage. If the voltage specified on the label or the plug
design of the AC adapter do not match the rating or standard you use, please
contact your Sartorius office or dealer.
tCheck the voltage rating and plug design.
tThe device must be plugged into a properly installed wall outlet.
Protection Class 1 Device
tThe device must be plugged into a properly installed wall outlet that has
a protective grounding conductor (PE).
Safety Precautions
3If you use an electrical outlet that does not have a protective grounding conductor,
ensure that an equivalent protective conductor is installed by a certified electrician
(as specified in the applicable regulations for installation in your country).
The protective effect must not be negated by using an extension cord without
a protective grounding conductor.
Before using for the first time, any superstructure parts must be completely
installed.
Avoid connecting the equipment to lines that have a heavy electrical load,
e.g. compressors, large machinery, etc.
Warm-Up Time
To deliver exact results, the device must warm up for at least 30 minutes after
connection to AC power. Only after this time will the device have reached the
required operating temperature.
