Actuator with lithium battery In the standard version, the actuator is provided with a lithium battery to keep visible the local position display, to back-up the RTC (real-time clock) for diagnostic functions, to test the battery charge, and to update the remote outputs (output relays status when set as “open limit” or “close limit” and 4 - 20 mA when externally supplied) in case of electrical power failure and manual override operations. The program runs the functions relevant to the battery only if the appropriate flag “lithium battery” is configured with “present”. If the battery is absent or if the above functions are not requested, the flag “lithium battery” should be configured with “absent”. ! CAUTION : For actuators provided with lithium batteries, make sure that the display is still visible when the power is off and that there is no “Battery low” Warning message. If the “Battery low” Warning appears, replace the battery (see Section 11.3, Lithium Battery Change). Always replace batteries if the actuator has been subjected to long periods without power (see Section 12, Troubleshooting). Configuration procedure
