Monitor ceases to work with a certain IMx-S unit
Possible causes:
•
Loss of voltage in IMx-S unit
•
Hardware fault in IMx-S unit, such as power supply or processor module
•
Break in Ethernet network
Suggested solution:
•
Check the voltage of IMx-S unit. In addition, check the Ethernet built-in LED
indicator behavior.
•
If the problem continues, you may also refer to "Application Note Testing and
troubleshooting IMx network connections" in Application notes which is access

Checking sensor and sensor cabling for analogue channels
1.
Determine the unit number and channel number of the channel in question
through the measurement point information in the software, or through the list
of terminal blocks.
2.
Measure the DC voltage between the sensor wires on the IMx-S terminal block
using a digital voltmeter. See the table below for the normal voltage values
with and without a connected sensor respectively.
