Sensor burnout occurs when PV or RSP input burnout occurs.

However, burnout is not detected if input is not connected.

Control computation

RSP terminal input (ON)/PV terminal input (OFF) switch

(Current when retransmission output)

(for Standard model)

DI16 is equipped when

suffix code: Type 2 = 1 or 4.

(E1-terminal area) can be used

when suffix code: Type 2 = 1 or 4,

and with optional suffix code /DR.

DI41 to DI45 are equipped when suffix

code: Type 2 = 0, 1 or 3.

The function is assigned to each DIs at

factory default.

Start of program operation
