Maintenance
Clock Battery Replacement
The HMI Display Real Time Clock is maintained by a non-rechargeable battery internal to the HMI Display.
Change the battery every ten years or as needed. The system will continue to function as an active filter with
a dead battery but HMI information (fault logs and trend plots) will not be maintained between power cycles.
To replace the battery, open the battery cover on the back of the HMI Display (see Figure 8.1) and remove
the old battery. Dispose or recycle the old battery in accordance with any applicable national, state/provincial,
and local requirements. Install new battery and close battery cover.
Replacement Battery Type: 3V Lithium CR2032 x Quantity 1
