Replacing the Backup Battery
A backup battery is built into the HG1F to retain the internal backup data (log data, keep resister, and keep relay) and
clock data.
When the “Replace the battery” message is displayed, replace the backup battery by following the procedure below.
When the “Battery level LOW” message is displayed, replace the battery immediately; otherwise, the backup data and
clock data may be lost.
Whether or not to display the reminder message for battery replacement can be specified with the configuration
software. Refer to Chapter 4 “3.1 System Tab” on page 4-26 for details.
1 Remove the battery holder cover.
2 Turn on the power to the HG1F, wait for approximately one minute, and then turn off the power again.
3 Insert a flathead screwdriver into the battery holder as shown in the figure, and remove the battery. Please be careful
because the battery may pop out from the battery holder.
4 Attach a new replacement battery to the battery holder.
Insert the battery from the direction indicated above.
After turning off the power to the HG1F in step 2 , complete the steps through 4 within 30 seconds in order
to replace the battery without losing the backup data and clock data. However, it is recommended that the
backup data be transferred to flash memory as a precautionary measure. For how to transfer the data to
flash memory, refer to Chapter 32 “Internal Devices” on page 32-1. If it is not necessary to save the data,
step
2 can be skipped.
