The load output settings also controls the streetlight algorithm. Both work together to protect the battery from being too deeply
drained. The streetlight settings are overridden should the battery voltage falls below the load disconnect voltage. When the
battery voltage increases to the load reconnect voltage, the streetlight function will resume.
5.2.3. Programmable relay settings
The programmable relay can be configured to a variety of relay modes. Each mode will cause the relay to switch under different
conditions. Some of these conditions are pre-determined and some are customizable. In addition to the "relay mode" a relay
minimum closed time can be set.
The programmable relay offers three connections:
• NO (Normally Open)
• C (Common)
• NC (Normally Closed)
