Terminals
AC
– power input (17-24 VAC).
COM
– common ground.
+12V
– power output (13.6-13.8 VDC).
AWS
– OC type output to indicate the loss of 230 VAC power.
AWB
– OC type output to indicate low voltage or failure of the battery.
In the normal state, the OC type outputs are shorted to ground (0 V), but when a trouble
occurs, the output is disconnected from ground.
