To replace the MPC Open XP's battery
The MPC Open XP's 10-year Lithium CR123A battery retains the following data for a maximum of 720 hours
during power outages: time, control programs, editable properties, schedules, and trends.
To conserve battery life, you can set the driver to turn off battery backup after a specified number of days and
depend on the archive function to restore data when the power returns.
A low battery is indicated by the
Battery low
LED or a low battery alarm in the i-Vu® application. You can purchase
replacement batteries from any retailer that sells a CR-123A battery.
1
Verify that the MPC Open XP's power is on.
2
Using a small flathead screwdriver, pry up each side of the black battery clip until it is free and you can
remove it.
3
Remove the battery from the expander, making note of the battery's polarity.
4
Insert the new battery into the expander, matching the polarity of the battery you removed.
5
Push the black clip back onto the battery until you hear both sides click in place.
6
Download the MPC Open XP.
To replace the fuse
If you turn on the MPC Open XP's power switch and the Power LED is not lit, use a multimeter to see if one of the 3
Amp Pico fuses that protects the incoming power is blown.
