Hakko Electronics Monitouch V9 Series, Troubleshooting Instructions Supplement

Page: 6 / 112

[General Notes]

Never bundle control cables or input/output cables with high-voltage and large-current carrying cables such as
power supply cables. Keep control cables and input/output cables at least 200 mm away from high-voltage and
large-current carrying cables. Otherwise, malfunction may occur due to noise.

When using the V9 series in an environment where a source of high-frequency noise is present, it is
recommended that the FG shielded cable (communication cable) be grounded at each end. However, when
communication is unstable, select between grounding one or both ends, as permitted by the usage
environment.

Be sure to plug connectors and sockets of the V9 series in the correct orientation. Failure to do so may lead to
damage or malfunction.

If a LAN cable is inserted into the MJ1 or MJ2 connector, the device on the other end may be damaged. Check
the connector names on the unit and insert cables into the correct connectors.

Do not use thinners for cleaning because it may discolor the V9 series surface. Use commercially available
alcohol.

If a data receive error occurs when the V9 series unit and a counterpart unit (PLC, temperature controller, etc.)
are started at the same time, read the manual of the counterpart unit to correctly resolve the error.

Avoid discharging static electricity on the mounting panel of the V9 series. Static charge can damage the unit
and cause malfunctions. Discharging static electricity on the mounting panel may cause malfunction to occur
due to noise.

Avoid prolonged display of any fixed pattern. Due to the characteristic of liquid crystal displays, an afterimage
may occur. If prolonged display of a fixed pattern is expected, use the backlight’s auto OFF function.

The V9 series is identified as a class-A product in industrial environments. In the case of use in a domestic
environment, the unit is likely to cause electromagnetic interference. Preventive measures should thereby be
taken appropriately.
[Notes on the LCD]
Note that the following conditions may occur under normal circumstances.

The response time, brightness, and colors of the V9 series may be affected by the ambient temperature.

Tiny spots (dark or luminescent) may appear on the display due to the characteristics of liquid crystal.

There are variations in brightness and color between units.
