12.1 Periodic Inspection
In order to use the RSEL system functions in the best possible condition, it is necessary to perform
daily or periodic inspections.
Danger
● Do not touch the terminal while live. This may result in electric shock.
● Connect the absolute battery correctly. Do not charge, disassemble, heat, throw into
fire, short-circuit or solder. Incorrect handling of the absolute battery may cause injury
or fire due to heating, rupturing or ignition.
● Always shut off the RSEL system power supply before cleaning or assembling/disassembling
the unit. Electric shocks may result if the power is not shut off.
● Malfunctions may result if the unit connections are tightened loosely.
Caution
● Do not disassemble or modify any unit. This may result in breakdowns, malfunctions,
injury or fire.
● Always shut off the RSEL system power supply before attaching or removing modules
or motor/encoder cables. If not shut off, module breakdowns or malfunctions may
result.
● Do not apply shocks to or drop the absolute battery.
Drops and shocks can damage the absolute battery, causing the liquid inside to leak. If
the absolute battery is dropped or suffers impact, do not use and instead discard.
● Before touching a unit, always touch a grounded metallic part to discharge any static
electricity accumulated on the body. If static electricity is not discharged, module
breakdowns or malfunctions may result.

12.2 Periodic Inspection Items
The RSEL systems contain electronic components that may degrade due to the operating
environment and require periodic inspection.
It is standard to conduct periodic inspection once every 6 months to one year, but the interval
should be shortened in accordance with operating environment.

Inspection details Judgment criteria Countermeasures
1
Power
supply
Measure between the
power supply terminal
block to check that the
voltage fluctuation is
within the reference range
Within voltage
fluctuation range
24 V ±10%
Adjust so that the power supply
voltage falls within the judgment
criteria.
2 Operating
environment
Ambient temperature
(If used in a panel, the
panel temperature is
the ambient
temperature)
0 to 55°C
Measure the operating temperature
with a thermometer and adjust the
environment so that it falls within
the ambient operating temperature.
However, simple absolute units and
SCON controllers are 0 to 40°C.
Operating humidity
(Panel humidity if using
in a panel)
85% RH or less,
non-condensing
Measure the operating humidity
with a hygrometer and adjust the
environment so that it falls within
the ambient operating humidity.
Atmosphere
No corrosive or
flammable gas
Check with an odor or gas sensor.
No splatters of
water, oil, or
chemicals
Remove and shield.
No accumulated
dust, debris, salt,
or metal powder
Remove and shield.
Directly exposed to
sunlight?
Out of direct
sunlight
Shield.
Subjected to direct
vibrations or impacts?
Vibration damping and
shock-resistant
specifications should
be within the range
Install a cushion, etc., for vibration
damping and shock resistance.
Close to a noise
source?
None
Move the noise source further
away or take shielding
countermeasures.
3 Mounting
status
Mounting state on each
DIN rail
No slack in unit
mounting
Re-attach and lock.
4 Connection
status
Units firmly connected?
The connector
should be
tightened firmly
Tighten so that it is no longer loose.
Cable between simple
absolute unit and driver
unit securely inserted?
Insert completely Insert again.
