Checking relay signal
1.
Determine the unit number of the alarming channel through the software
measurement point setting or though the list of terminal blocks.
2.
Disconnect the relay connection from the IMx-S unit in question. Carefully
check to see if the relay output caused to trip the machines. Measure the
voltage between the alarm relay poles.
3.
Has the relay been activated (voltage approximately 12 V)?
YES: The fault is in the cabling or output connections from IMx-S.
NO:
Check the software configuration for measurement point settings to find
out whether the channel in question is allowed to activate the alarm relay. If
this is not the case, then change the setting. Contact SKF Condition Monitoring
Center Luleå, if the channel is permitted to activate the relay, but does not do
so.
Checking monitor
1.
Check first, whether the @ptitude Observer Monitor or Analyst IMx Service PC
is functioning as it should be.
2.
Try restarting the computer, if there is any doubt as to the status of the
@ptitdue Observer Monitor or Analyst IMx Service software.
3.
Check also that the Ethernet network is functioning and that the Observer
Monitor or Analyst IMx Service computer can write to the server disk.
Checking modbus communication
1.
Start @ptitude Observer On
-line Device Configurator located in the @ptitude
Observer directory.
2.
Click
Start serial interface.
3.
On the Serial interface screen, enter the COM port number and type in the
word "modbus"
in the command box.
4.
Statistics on communication and the contents of the import registers will
appear on the screen.
The statistics are:
-
Frame errors (short and long)
-
Checksum errors
-
The number of messages sent
-
The number of messages received
-
The number of timeouts of requests
5.
A properly working Modbus communication should exhibit increasing sent and
received messages, but not exhibit significant increase of errors or timeouts.
