Maintenance and Inspection
The FL Remote ID must be inspected on a daily or regular basis so that the functions can be used in good
condition. The FL Remote ID consists of semiconductors that last almost indefinitely. The following
malfunctions may, however, result due to the operating environment and conditions.
(1) Element deterioration due to overvoltage or overcurrent.
(2) Element deterioration due to continuous stress caused by high ambient temperature.
(3) Connector contact faults or insulation deterioration due to humidity and dust.
(4) Connector contact faults or element corrosion due to corrosive gas.

5 Mounting condition
(1) Check that each device is securely
mounted.
No loose screws
---
(2) Check that each connector is fully
inserted.
Each connector must be
locked or securely tightened
with screws.
---
(3) Check that no screw of the terminal block
is loose.
No loose screws

6 RF Tag life
Use the RF Tag service life warning function
and manage the number of times the RF Tag
has been written.
Do not allow the specified
maximum number of over-
writes to be exceeded.
