Hysteresis can be set in the alarm setpoint.
Setting hysteresis prevents relays from
chattering.
An alarm is output when the delay timer expires
after the alarm setpoint is reached.

21: Fault diagnosis output
Turns on in case of input burnout, A/D
converter failure, or reference junction
compensation (RJC) failure.
22: FAIL output
Turns off in case of program failure, ROM
failure, RAM failure, or power failure. This
output is on during normal operation. If it
turns off, the retransmission output is set to
0%, the alarm output is set to OFF, and the
indicator stops.

Useful Operating Display (SELECT Display)
Registering frequently changed parameters in the SELECT display after ordinary operating displays will allow you to
change settings easily. A maximum of four displays can be registered.
Setting method:
Set the parameter numbers (D register numbers) you wish to register for
setup parameters C.S1 to C.S4.
