APPENDIX-O: ISOLATOR SUPPORT
Isolator support feature allows a device with an isolator to report alarms as well when a short
circuit or open circuit happens on the device.
The wiring of the device with an isolator and the setting of its corresponding “Isolator Support”
checkbox on FXS901 tool should be consistent, otherwise, the system reports trouble. For
example, when a device with an isolator is wired as an isolator module, then the “Isolator
Support” checkbox should be ticked as True. In the auto configuration mode, the “Isolator
Support” checkbox is ticked as true automatically when the device is wired as an isolator
module.
Separate isolator modules and isolators on devices can’t be used on the same circuit,
otherwise, the system reports trouble. If separate isolator modules are used, the devices with
isolators must be wired as non-isolator modules.
Below table listed out the devices which have isolators and their supported versions:
