Inspection description
(i) Determine whether it's within standards
by checking power supply terminal
strip.
(ii) Is there frequent instantaneous power
drops or sudden voltage fluctuations?
(i) and (ii): Within specifications?
(iii) Is there vibration or impact transmitted
from machinery?
(iv) Is dust or foreign matter is adhered to
controller, and has it accumulated?
(v) Is the metal casing discolored or
corroded?
(i) Is the natural air flow/forced air
flow/cooling operating well?
(ii) Is the packing attached to the panel
coming off or damaged?
Are measurements of the terminal strips in
each I/O section within specifications?
(i) Are all devices secured properly?
(ii) Are all connectors completely inserted?
(iii) Are the screws on the terminal strips
loose?
(iv) Is the wiring about to break?
(v) Is distance between DC and R/W
Heads within specified range?
Check DC production date
Check error data
Note The DCs have built-in lithium batteries for memory backup. When the batteries
are drained or become unusable, please dispose of properly as it is extremely
dangerous to burn them. Fires must be avoided.
