Tasks
Close the cabinet doors before performing identification run to guarantee normal operation
conditions concerning air flow.
On the first start, the control program performs identification run for the fans to detect the 100%
rotation speed level. Identification run is performed whenever the control program detects fans
without existing identification run results and fans are commanded to start. When the identification
run is finished, the control program shows the detected results (100% level feedback pulse
frequencies) in the parameters of parameter group
fans are ready for use. Note:
• Verify that the detected feedback pulse frequencies are reasonable for the fan types. For allowed
reference speed ranges, see the sticker inside each cabinet door.
• If identification run needs to be performed prior to starting the complete device, set parameter
206.04 Force fans on to Enable. Every start of fans performs the identification run for fans that do
not have an existing result available.
• If fans are later replaced with new ones, identification run result and internal run-time counters on
the CIO-01 module need to be reset. To reset, set parameter
fan data and trigger the operation with parameter
node.
• If CIO-01 module is replaced, all the fans connected to the replaced CIO-01 module need to be
replaced as well. Otherwise the run-time supervision does not work properly.
Review the parameters of parameter group
limits etc. are suitable for the application.
