2.0 Installation
Rice Lake Weighing Systems recommends the instrument and the platform (transducer) be installed on a flat level surface, that
is stable and vibration free.
2.1 Location Selection
The following should be considered when selecting a location for the equipment:
• Dust-free
• Free of strong breezes or vapors
• Moderate temperature and humidity (59 to 86°F and 40-70%)
• Use waterproof conduit and couplings in order to protect the load cell cables
• Use a waterproof junction box to connect the cells
• Avoid welding with load cells installed
During operation, unit will get hot
When the SCT-2200 is installed in inside of the electrical panel, it is recommended that the units be installed vertically to a
horizontal DIN rail. This minimizes heat buildup from multiple units being stacked and also enables optimal ventilation through
the unit. If possible, it is recommended that the unit be installed towards the bottom of a panel to avoid the warmest parts of the
panel. If panel size is small, some air circulation may be required.
2.2 Electrical Precautionary Measures
The following electrical precautionary measures must be considered when installing this equipment:
• Main power supply must be maintained within ± 10% of the rated voltage
• Electrical best practices must be observed by the installing technician
• Follow recommended minimal separation distances given for cable categories, See Section 2.3
• The cable extension of the load cells, or signal amplifiers connecting to the serial ports and analog output, must be within stated maximum
lengths, See Section 2.3
• It is recommended that load cell cables are shielded and run in conduit at an acceptable distance from power transmission lines to avoid
signal interference and signal noise
• All cable runs not in conduit or otherwise shielded should be of minimal length and terminated as close to conduit exit as possible to avoid
extraneous signal noise
• If the instrument is situated inside an electric panel, the power supply cable must be shielded and as short as possible, separate from every
coil supply cable, inverter, electromotive force, and others. In addition, provide dedicated power supply to the instrument
• Install RC filters on the contact coils, solenoid valves and all devices producing electric fields
• It is recommended to leave the instrument powered on at all times to avoid condensation forming on the inside of the instrument
2.3 Maximum Cable Length
2.3.1 Load Cell Cable
The maximum length of a standard load cell cable with sense wires is:
• 150’ at 30#AWG
• 300’ at 24#AWG
2.3.2 RS-232 Cable
The maximum length of an RS-232 cable is 50' at a maximum baud rate of 19200.
2.3.3 RS-485 Cable
The maximum length of RS-485 cable is 4000', See Section 6.1 on page 35 .
2.3.4 Analog Output Cable
The maximum length of the analog current output cable at 4-20mA is 300'.
The maximum length of the analog voltage output cable at 0-10Vdc is 150'.

2.4 Grounding the System
A centrally located, single point ground, such as the ground bar of the electric panel, must be created and/or identified for
proper grounding and functioning of the system. The ground must be sized so that the total resistance of grounding is lower
than 1Ω. Connect grounding points of all instrumentation, load cells, and weighing structure to this single point ground.
2.4.1 Load Cells and Junction Box
When the load cells are connected to the instrument through a junction box, the shielding of the load cell cables and the
instrument must be connected to the junction box grounding.
When the load cells are directly connected to the instrument, the load cell cable shielding must be connected to the single point
ground.
System cabling should be kept as short as possible to minimize noise potential. After exiting conduit or other shielding, a ferrite
device should be used prior to conductor termination.
After platform and the load cell are properly grounded, connect the shield from the load cell cable to the instrument ground. See
Figure 1-1 on page 3.
Figure 2-1. Grounding Example
Procedures not expressly described in this manual are considered improper use of the equipment.
Ensure the platform is level or the load cells are shimmed evenly.
All connections must meet all local zone and environment standards.
Follow the recommended electrical precautionary measures described in Section 2.2 on page 5.
Make sure that the grounding is made correctly, See Section 2.4 on page 6.

2.6 Connection to the Load Cell
The load cell terminal board of the SCT-2200 must be connected to the 6-wire load cell; if using a 4-wire load, cell excitation
must jumper to sense.
Sense is always enabled and, when not using 6-wire load cell, the sense terminals must be jumpered to the
same polarity excitation wires.
The sense compensates for drops in voltage along the cable that connects the instrument to the load cell. Voltage is
lost when the instrument and the load cell are greater than 30ft apart. A cable is typically provided with a load cell.
When exceeding the length of the provided load cell cable, six wires must be used to compensate for voltage drop. It
is, however, recommended to never cut or shorten the load cell cable.

3.5.2 Alibi Memory
The alibi memory allows for transmitted weight values to be filed in the PC for data processing and/or integration. The filed
values can then be recalled from the PC serial line or directly on the instrument’s display for a following check.
Storage of a weight value occurs following the reception of the serial command or by pressing . The instrument transmits
the gross and tare weights and an ID on the serial port.
The ID has the format: <Rewriting number>-<Weigh number>
• The rewriting number is a five digit number from 00000-00255; it indicates the number of complete rewritings of the alibi
memory
• Weigh number is a six digit number from 000000-131072; it indicates the weigh number in the current rewriting of the
alibi memory. The weigh number is increased by 000001 with each weigh storage. Once the value reaches 131072, it
restarts from 000000.
The storage of a weigh value occurs only if the gross weight is greater than or equal to zero, it is stable and valid (not in under-
load or overload). Depending on how  has been configured in the technical set up, the storage of a weight by
pressing a key is possible only if the condition is met (weight exceeds zero, weight instability or always).
