Changing the Battery
The unit comes with a built in Lithium battery with a 5 year life expectancy. The steps below outline the process to
change the battery inside the unit. Since only the information saved to the registers/discretes available on a power
cycle will remain intact, please save pertinent information before attempting to change the battery. Then remove
power from the unit.
1.
Open the back cover to access the battery.
2.
The battery is located in the upper-left hand corner as shown in the figure below. Remove the old battery and
replace with a new 1/2 AA, 3.6 V Lithium Battery (Part Number: EZ-BAT).
3.
Close rear cover and ensure that the door latches.
4.
Reconnect power source. Connect to PC and run the Programming Software to transfer back the user program
to the EZ3-TouchPLC Modular.
The Real Time Clock (RTC) will need reset after the battery has been replaced. All information saved to the
registers/discretes available on a power cycle will remain intact. Data not saved to registers/discretes available during
a power cycle will be lost.
