Description
Down 1
No. of Sensors
The number of sensors being polled by the bus
converter is displayed
Down 2 -33
Serial Number Display
Displays the serial numbers of the sensors being
polled by the bus converter
Up 1
Data Signal
The data line average voltage. The data line
should be above 3.5VDC.
Up 2
Power Signal
The power line average voltage. The power
supply should be above 4.5VDC.
The values displayed above can be used to further troubleshoot the system. If the display indicates an
error, use the standard troubleshooting procedure starting at the first field interconnect box to isolate
portions of the network. If the error is corrected when a branch is isolated, the problem will be in that
branch. Continue to the next field interconnect box and repeat until the field interconnect box causing
the error is found. The sensors in that box can then be individually tested to locate the defective
sensor.
3.4 Sensor Emulator
The tester can emulate most CMC sensors. Sensors that can have multiplexed output modes such as
the mTS017 and mVM001 will only be emulated as single mode devices. The mTC001 and mTC002
Thermocouple converters cannot be emulated. To emulate a sensor follow these steps:
1.
Select “
Emulate Sensor
” from the main menu;
2.
The display will indicate:
3.
Once connected, the display will indicate the serial number of the sensor being emulated;
4.
After displaying the serial number the display will indicate;
