Battery low
The dry contact J8 terminal is used for signalling the battery charge level (low
charge). If the battery voltage is lower than the configured value, this information is
transmitted by J8 output. Depending on the NC (normally closed) or NO (normally
open) configuration, changing the state to the other one means the battery charge is
low. Fig. 33 presents the manner of making the connection. Table 8 presents the
pinout and the relevant description.
