10-6 Inspections
Perform regular inspections to ensure that the FL-net Unit is functioning to its
optimum capacity.
Items
Most of the parts that make up an FL-net Unit are semiconductor compo-
nents. None of the parts in the Unit will wear out after a specific lifetime, but
some parts may deteriorate due to extreme operating conditions. Therefore, it
is important to inspect the Unit regularly.
Inspection Interval Normally inspect once or twice per year. Choose the inspection period
according to the severity of the operating conditions. New installation should
be inspected more frequently until they are judged to be stable.
Inspection Items Correct any of the items in the table below not conforming to the specified
standard
Tools Required for Inspection
The following tools are needed to inspect the FL-net Unit:
Standard Tools • Flat-blade and Phillips screwdrivers
• Tester or digital voltmeter
• Industrial alcohol and a clean cloth
Tools Required Under
Special Circumstances • Synchroscope
• Pen oscilloscope
• Thermometer and hygrometer
Replacing CS1W-FLN12 with CS1W-FLN22
Use the following procedure to replace CS1W-FLN12 with CS1W-FLN22.
1,2,3... 1. Read the CS1W-FLN12 settings using the CX-FLnet or FL-net Unit Sup-
port Software.
Note The IP address setting method must be changed in the system settings if it is
set to use either the rotary switch on the rear of the Unit or the rotary switch
on the rear of the Unit + the node number. Refer to the following information
under
Changing the IP Address Setting Method .
2. Set the hardware switches of the new CS1W-FLN22 to the same values as
the CS1W-FLN12 being replaced. Use the rotary switches on the front of
the Unit to make these settings.
• Unit number setting rotary switch
• Node address setting rotary switch
