9.1 Regarding RTC (Real Time Clock) Backup Voltage Drop
9.1.1 Action to Take after RTC (Real Time Clock) Backup Voltage Drop
A display of “No. 187 RTC Backup Voltage Drop” error indicates the battery has become depleted.
(Reference)
Battery Life
The nominal life time the supplier has announced is approximately 5 years (at ambient temperature 25 qC).
If the battery gets depleted, you will lose the following data:
• Time data (Note 1) ,
• TP parameters
(Note 2)
such for language setting and model specification setting,
• Calibration values of touch panel, and
• Values of LCD contrast and brightness
(Note 3)
(Note 1) Set the current time every time turning the power on. The current time data is maintained until the
power is turned off. The date when storing a file to an SD card is also based on the current time.
If the current time setting is not conducted, the current time will show the time passed since 00/01/01
00:00:00 when the power is turned on. The date of file storage to an SD card will show the time
passed since the power is turned on.
• CON related controllers [Refer to 5.17 Environment Setting]
• SEP controller [Refer to 6.14 Environment Setting]
• MEC controller [Refer to 7.14 Maintenance Environment Setting]
(Note 2) For CON-PDA/PGA, if the TP parameters are initialized, the model turns to CON-PTA, thus the
setting is turned to that not to use the enable switch. When connected to a controller with the enable
effective and turn the power on, you will be asked if you may invalid the setting. Select “No”. The
dead man’s switch can be used.
If “Yes” is touched accidently, the setting becomes invalid, thus the dead man’s switch becomes no
longer available. In this case, make the setting in Parameter No. 42 Enable Function of CON related
controller to 0 = Effective.
[Refer to 5.8 Parameter Editing]
(Note 3) Readjust the contrast and brightness of the screen if an adjustment has already been made to those
settings.
• CON related controllers [Refer to 5.17 Environment Settings]
• SEP controller [Refer to 6.14 Environment Settings]
• MEC controller [Refer to 7.14 Maintenance Environment Setting]
9.1.2 Battery Replacement
The battery cannot be replaced with the user’s responsibility.
Please contact us if a replacement work is needed.
