Maintenance
■ Use the cable gland connection or metal pipe line lead-in on the wire inlet, and use
a product with an equivalent ex-proof certificate to connect it using the external line
lead-in method.
■ For an unused external line inlet, use a closing plug with an equivalent ex-proof certificate.
■ Precautions for ground connection
- The location of the external ground is as follows, and when connecting to the ground
wire must be 4
㎟
(4mmSQ) or more. (Internal grounding should be connected with
the same specifications as the connection cable.)

■ Inspection
The sensor and transmission parts of a capacitive-level transmitter must be inspected.
Their service lives depend on the user environment and can be optimized with regular
inspection. As such, users are advised to conduct regular inspections and maintenance at
least every year. The exterior damage will be visually inspected, and any object to be
measured and foreign substance will be regularly removed from the probe as these can
affect accuracy.
When removing them, prevent causing damage to the Teflon.
■ Failure Check
1) Is the power connected correctly?
2) Is the power voltage correct?
3) Is the cabling correct?
4) Is the green LED turned on?
During maintenance, the power to the product must be completely cut off
before inspection.
Do not disassemble while power is applied in an explosion-proof area.
