PMIU unit has dry battery for RTC and backup memory area. Life time of battery is about 5 years (It may very
shorten depending on the operational environment).
RTC and back up memory area has 2 power sources, this battery and the power supplied to PMIU unit. If unit
power is supplied, even if the battery is running out, these are not lost (these are backed up by unit power).
If unit power is OFF and battery is running out, these data are lost. So, you should do following operation with
the unit power supplied to keep these data, and please note if you left PMIU unit without power supply for long
term.
You can know present battery voltage by System tag SW 0007 (Battery voltage), and when the voltage of
battery falls below 2.2V, System tag S0010 (Battery status) is turned ON. If S0010 is turned ON, you must
replace battery immediately.
To get new battery, please contact us. This battery is special one, the connector board is spot-welded
Step 1.
Detach battery cover
Detach battery cover from unit (Battery cover exists at the top of the PMIU unit). If you use
expansion port slot 2 of TRPMIU0300A or expansion port slot 3 of TRPMIU0500A, switch unit to
HALT mode (write the value “1” to system register tag MW0000 or MW0003) and remove the
Expansion I/O unit attached to the slot.
Step 2.
Remove old battery
Battery is installed in the back side of battery cover, and Battery wire is connected with the
internal circuit of the unit.So as not to misunderstand the old battery and the new one, you should
mark old battery. Pull out the connector of battery wire from battery. Do not pull wire, hang the
finger on the projection of the connector, and pull it out straight. Then, Remove old battery from
the battery cover. Battery is supported with 2 tabs and 2 pins of the cover.
Step 3.
Install new battery
Insert new battery to battery cover. Set the battery noting the direction of the battery and two
pins. Then, connect connector carefully in the direction. The connector cannot be inserted
oppositely. When inserting it by force, connector is damaged. When you connect the connector,
install the battery cover in unit. Do not place the wire by the cover.
Step 4.
After replace battery
The data of RTC and backup memory area will be lost. Before start operation, check and reset
these data.
When you work with power ON, use safety equipments, and be careful to prevent hazard.
To prevent unexpected battery run out, the recording of the time when you should replace battery, or the
recording of the date when you replaced battery is recommended. It may help daily maintenance to stick those
dates on a PMIU unit with labels.
