mA output signal during system error

This function determines how the mA output should act in

case of a system error.

System errors are most often caused by a weak or missing

ultrasonic echo, but may also occur by failure of the ultra-

sonic sensor or failure in Shuttle

's internal circuits.

Select the desired condition with the arrow keys.

The mA output will be locked on the last known value when

a system error occurs.

The mA output will give a ﬁxed signal when a system error

occurs.

Select the desired value (0.35 to 20.5 mA) of the ﬁxed signal

with the arrow keys.
