RAS information Status Troubleshooting
E1: Device error 1 Backup memory failure See “6.5.7. Remedying a hardware fault”.
E1: Device error 2 Abnormality of measuring circuit Turn the power off then on again. If the
instrument does not recover properly, refer to
“6.5.7. Remedying a hardware fault”.
E2: Data collection error Ultrasonic send/receive signals cannot be
collected.
E2: Window scanning The ultrasonic receiving signal waveform is
being detected.
Move the mounting position of the detector,
and remount the detector.
Repair or replace the signal cable.
Transmitter circuit failure or detector failure

See “6.5.7. Remedying a hardware fault”.
E2: No received signal No ultrasonic receiving signal waveform
E2: Received signal error The status of received waveform is poor. Check the air bubbles or foreign objects.
Check the receive sensitivity.

Move the mounting position of the
detector, and remount the detector.
E2: Received signal
range over
Receiving signal waveform is outside the
appropriate range.
Check the piping data.
Check the detector mounting dimensions.
E2: Calculation failure The value of detected measurement data is
abnormal.
Check the piping data.
Check the receive sensitivity.

Move the mounting position of the
detector, and remount the detector.
E4: Range over Analog output and total output exceed the
range.
Check the range data and the totalize
setting.
Correspondence between DO output and Alarm
“
All” : Alarm is issued at occurrence of E1 or E2. [Burnout timer is enabled]
“
Device error” : Alarm is issued at occurrence of E1. [Burnout timer is disabled]
“
Process error” : Alarm is issued at occurrence of E2. [Burnout timer is enabled]
Burnout timer is to set a time between error occurrence and contact output.
