1) A gas detection system using Modbus RTU. Detectors are wired in a daisy
chain on a single cable run.
2) A gas detector system using analog current loop principle. Each detector
is individually wired to the controller on its own cable.
Final positioning of gas detectors should be indicated by the
characteristics of the gas being detected and other environmental
factors. Seek advice from experts where necessary.
Sensepoint XCL requires a power supply from the controller of specified
supply voltage range in Section 1.7. Ensure that a minimum supply
voltage is measured at the Sensepoint XCL, taking into account voltage
drops due to cable resistance.
