* After the control output terminal is specified by the parameter OT,

other current output terminals can be used as retransmission output.

Sensor burnout occurs when PV or RSP

input burnout occurs.

However, burnout is not detected if input

is not conncted.

Input ladder calculation program (signal goes to the control computation as is when without ladder program). For ladder program, see the LL50A Parameter Setting Software User’s Manual.

Manual output is prioritized even if

sensor burnout occurs in MAN.

For the model with optional suffix code /DR:

Remote input with direct input

(E1-terminal area) can be used

when suffix code: Type 2 = 1 or 4,

and with optional suffix code /DR.

However, DI16 is to be deleted.
