Keypad Battery Low Voltage

What does bAT mean?

The keypad battery voltage has fallen below the acceptable threshold, indicating a low power state. If left unaddressed, this can lead to loss of real-time clock functionality or stored parameter values on the keypad. It is a precursor to complete battery failure.

• The keypad's internal battery has reached its end of life and can no longer hold sufficient charge.
• Extended periods of the drive being powered off, causing the battery to drain without recharge (if applicable).
• A defect in the keypad's battery charging circuit, preventing proper recharging.
• Incorrect battery type installed (if user-replaceable), leading to rapid discharge or incompatibility.

1. 1

   Locate the battery compartment on the keypad (often on the rear) and carefully open it.

2. 2

   Replace the old battery with a new, compatible type (e.g., CR2032 lithium coin cell) as specified by the manual.

3. 3

   After battery replacement, navigate to the keypad's time and date settings and reset the real-time clock.

4. 4

   Verify the keypad's diagnostic menu (if available) shows the battery voltage as acceptable.

5. 5

   Ensure the keypad is properly seated and connected to the drive to allow any charging functionality to operate.
