1. Introduction
The 2150 is a dedicated baggage weigher. It is a precision digital indicator using the latest Sigma-
Delta A/D converter to ensure extremely fast and accurate weight readings.
The setup and calibration are digital, with a non-volatile security store for all setup parameters.
There is an NVRAM store to ensure day to day operating settings (eg. <ZERO>, <TOTALS>,
etc.), are retained when power is removed. There is a built-in clock for date-stamping printed
outputs and the current time can be set to display at the top right of the instrument display.
The instrument has up to three internal setpoints with status display on the front panel. There are
three Input/Output points on the auxiliary connector. Each one may be configured as a remote
input or as a setpoint drive output.

3. Installation
3.1. Introduction
The 2150 contains precision electronics and must not be subject to shock, excessive
vibration or extremes of temperature, either before or after installation.
The inputs of the 2150 are protected against electrical interference, but excessive levels of
electro-magnetic radiation and RFI may affect the accuracy and stability of the instrument.
The 2150 should be installed away from any sources of electrical noise. The load cell cable
is particularly sensitive to electrical noise and should be located well away from any power
or switching circuits. For EMC immunity, termination of the load cell shield at the 2150 end
is important (ie. with a sound connection to the 2150 case via the DB9 backshell).
3.2. Panel Mounting
The simplest way to mount the 2150 is to use the drill template supplied. The template
indicates positions for the drill holes for the two 4mm mounting screws through the panel.
Also displayed on the template is the position of the rectangular hole that should be cut to
allow for the connection of cables and also to display connection instructions. The drill
template supplied with the indicator allows for front or rear machining of the panel.
An optional gasket (P/No 0348) is available for panel mounting installation.
3.3. DC Power Supply
The DC supply need not be regulated, provided that it is free of excessive electrical noise
and sudden transients. The 2150 can be operated from a high quality plug-pack as long as
there is sufficient capacity to drive both it and the load cells.
Note that the rated voltage of most plug–packs is specified for loads close to but less than
their rated output. If substantially lower loads are used the voltage output rises. Conversely
if the plug pack is run at its maximum load the voltage will drop and it will run very hot.
Typically plug packs with a rating of 9VDC to 12VDC with current outputs of 0.5 to 1A are
fine. The Plug Pack 500mA, option (P/No 0110) is recommended for use with the 2150.
Figure 2: Power Connection
3.4. Load Cell Signals and Scale Build
Very low output scale bases can be used with the 2150 but may induce some instability in
the weight readings when used with higher resolutions. Generally speaking, the higher the
output, or the lower the number of divisions, the greater the display stability and accuracy.
The 2150 has a milliVolt-per-Volt reading available which can be used to check scale base
signal output levels. For more information refer to SCALE (Scale Base Test Display) page
34.

3.5. Connecting Shields
To obtain full EMC resistance with the 2150, the load cell shield MUST be connected
electrically to the metal shell of the DB9 connector.
The easiest way to connect the cable shield to
the DB9 backshell is to fold the shield wires
back over the outside of the cable insulation so
the cable clamp of the backshell makes good
electrical contact with the shield when
installed.
A method for connecting the cable shield to the
DB9 is to twist the shield wires together and
solder the ends to the DB9 casing.
Figure 3: Cable Shield Connection
3.5.1. Cable Shield Connection and Earthing
• Care should be taken when connecting shields to maximise EMC immunity and
minimise earth loops and cross-talk (interference) between instruments.
• For EMC immunity, termination of the load cell shield at the 2150 end is important (ie.
with connection to the 2150 case via the shield connection).
• The 2150 enclosure is directly connected to the shield connections on the cables.
• The 2150 should be connected to earth via a single reliable link to avoid earth loops.
• Where each instrument is separately earthed, interconnecting cable shields should be
connected at one end only.
• Caution: Some load cells connect the cable shield directly to the load cell (and therefore
the scale base). Connection of the shield in this situation may be site specific.
• The unit complies with relevant EMC standards provided case ground connection is
correctly made. Resistance measured between 2150 case and nearest earth point
should be less than 2 ohms.
3.6. Unused Pins
It is important to note that unused pins are not to be connected. The reason being that
the functions of the pins may not be compatible with equipment at the other end (eg.
connecting output pins to a PC communications port may affect the operation of the PC).
Consequently many commercial communications cables are not suitable for use.

3.7. Load Cell Connection
The following provides information on 6-wire and 4-wire connections.
3.7.1. 6-Wire Connection
The connection is made using a standard DB9 male plug that is supplied with the indicator.
The load cell is wired for a 6-wire system as follows:
Pin Function
1 Positive Excitation
2*Positive Sense
3 Negative Excitation
4*Negative Sense
8 Negative Signal
9 Positive Signal
*Sense lines MUST be connected.
Table 1: 6-Wire Connections
*For more information on Connecting Shields refer to page 9.
Figure 4: 6-Wire Connection
When wiring load cells, use only high quality shielded multi-core cable. The cable should be
run as far away from any other cabling as possible (minimum separation distance 150mm).
