If the "Error" symbol is displayed...
If the Mainfall shows "ERROR" but the Slope shows a value, the
Mainfall is not functioning.
If both Mainfall and Slope show "ERROR", the problem is in the
Control Box, or the Control Box to the Mainfall Cable.
Figure 7-11.
Rotation Sensor Test
Unlike the two previous sensor test procedures, the Rotation Sensor
Test displays in degrees of rotation rather than percentage of slope.
NOTICE
NOTICE
The Rotation Sensor information is communicated to the
Control Box from the Slope Sensor. If the Slope Sensor or
Slope Sensor Cable is defective, the Rotation Sensor will
also indicate "ERROR". If both are indicating error, proceed
to slope sensor test before conducting Rotation Sensor
Tes t .
