Perform maintenance operations to keep the NSH5-series PT in optimum
condition.
Do not disassemble the PT or touch the inside of the PT while the power is
turned ON. Doing so may result in electrical shock.
Be sure to back up project data and store it in a secure location, in case the
PT should have to be sent out for repairs or be replaced.
It is recommended that a spare PT be kept on hand, in order to enable faster
system recovery in case the original PT should be damaged or the screen
cannot be read due to reaching the end of the backlight service.
If the brightness of the backlight is diminished and the screen becomes diffi-
cult to read, the backlight must be replaced. A backlight cannot be replaced by
the user. If this situation occurs, please contact an OMRON representative.
Ordinarily a backlight would need to be replaced after approximately 75,000
hours at normal temperature and humidity. The service life is shortened in an
extremely cold environment. Replace the backlight if the brightness dimin-
ishes and the screen becomes difficult to read.
Screen data such as calendars, clocks, and log data are backed up by a lith-
ium battery. The battery service life is approximately five years when used in
an environment with a temperature of 25°C. If the temperature at the location
of use is higher than this, the battery life will be shortened. Change the battery
at suitable intervals in accordance with the operating environment.
It is recommended that a spare battery be kept on hand so that the battery
can be quickly replaced when necessary.
