Chapter 2 Installing the ICA1 and ICA2 S and H
Pre Installation
See Specification details in Chapter 8 for details of Environmental Approvals.
Carefully remove the ICA unit from its shipment box. Check that the unit is complete and undamaged.
The ICA units can be operated in any industrial environment providing the following limits are not exceeded.
The following installation practices are advised:
Minimise vibration
Do not mount next to strong electrical fields (transformers, power cables)
Ensure easy access to the module
Install electrical protection device as the unit is not internally fused
Always ensure the package is secure and protected
Figure 2.1 Dimensions
The module is designed to fit in the strain gauge pocket. Use the 2.1mm hole to secure the unit if required.
The mounting hole will accept an M2 screw or American equivalent #0-80.
Important Note: DO NOT USE #2 screw size.
Take care soldering cables to the pads.
Use a temperature controlled soldering iron set to a maximum 330 ºC, for no longer than 2 seconds per pad.
Excessive heat or increased soldering time may result in damage to the PCB.
If changing resistor 'R' do so at a workbench and not on site.
Check the relevant details for model ICA1 and 2, – ensure the module matches the instructions –
The ICA1 and 2 solder pads are as shown in the wiring diagrams:
4 pads for the strain gauge.
3 pads for power supply and output.
The fixing screw hole provides a ground connection to improve EMC performance.
Power Connections
The power supply for the ICA1 is nominally 24V dc (between 13 and 28V) and ICA2 is nominally 12V dc (between 8.5
and 28V).The power supply is commoned with the output at the 'com' connection.
