Chapter 1 Maintenance and Inspection
Periodic inspection items
The RCON 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.
No.
Inspection details
Countermeasures
1
Power
supply
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)
95% 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.
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?
and shock-resistant
specifications should
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
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
unit securely inserted?
Insert completely Insert again.
