4.2.2 External Monitoring of the Operation Mode
The J1 connector consists of status outputs that can be used to exter-
nally monitor the operating condition of the unit. The status outputs
consist of the following five items.
The outputs are open collector outputs of photocouplers; they are
insulated from the internal circuits of the unit.
