(1) If an input is not being used, an input error will occur and an over range
error and off-wire condition will be detected. This will cause the Temper-
ature Input Warning Flag in the Warning Status Area and the Off-wire De-
tection Flag in the Alarm Status to turn ON. If the Temperature Status
Flag is used, the Off-wire Detection Flag will turn ON. In addition, the
ERR indicator will light.
(2) Disable detecting input errors only for inputs that are not being used. If
this function is used when a sensor is connected, input errors and
Off-wire conditions will not be detected.
If an input sensor is disconnected, the Temperature Input Warning Flag in the
Warning Status Area and the Off-wire Detection Flag in the Alarm Status Area
will turn ON. If the Temperature Status Flags are being used, the Off-wire
Detection Flag for the input where the sensor is disconnected will turn ON. If
off-wire detection is enabled, the value of the conversion data will be set to
7FFF hex. (The value in 1/100 display mode will be 7FFFFFFF.) If the input
temperature returns to the convertible range, the off-wire detection function
will be reset automatically and normal conversion data will be stored.
The last maintenance date can be set in the Unit separately for the Unit and
the connected devices. It enables the user to easily determine the next main-
tenance date. The date can be set using the Configurator.
