COMMUNICATION LEDS — The LEDs indicate if the
controller is communicating with the devices on the network.
See Tables E and F. The LEDs should reflect communication
traffic based on the baud rate set. The higher the baud rate the
more solid the LEDs become. See Fig. B for location of LEDs
on UPC Open module.
REPLACING THE UPC OPEN BATTERY — The
Open controller's 10-year lithium CR2032 battery provides a
minimum of 10,000 hours of data retention during power
outages.
IMPORTANT: Power must be ON to the UPC Open when
replacing the battery, or the date, time, and trend data will
be lost.
Remove the battery from the controller, making note of the
battery's polarity. Insert the new battery, matching the battery's
polarity with the polarity indicated on the UPC Open
controller.
