Troubleshooting - Signet 8150 Manual

16. Troubleshooting

Display Condition
The À ow rate display
is erratic and non-linear
17. Flow and Total K-Factor Selection
Pages 17-19 provide K-Factors for the Signet
515 and 525 À ow sensors. Use this table to
convert the K-Factor to other units of measure,
and to set the Total K-Factor.
NOTE:
• The maximum K-Factor is 999999.
• The minimum K-Factor is 0.001.

Probable Cause
Batteries are dead or missing
The À ow rate is greater than
"9999"
8150 is not receiving a signal from
the À ow sensor.
In AutoCal, the calculated K-Factor
is outside the range of the 8150.
(less than 0.001 or greater than
99999)
Usually caused by inadequate
straight pipe run upstream of
sensor.
Both batteries are too depleted
to safely store settings.
FLOW RATE to read in:
Replace both batteries.
1. Reduce the À ow rate.
2. Change the Timebase to a smaller value.
(Example: Change from "Day" to "Hour".)
3. Change the À ow units to a larger measure.
(Example: Change from "Litres" to "Gallons".)
NOTE: If the Flow K-Factor is changed, be sure to make a
corresponding change to the TOTAL K-Factor.
1. There is no À ow in the pipe.
2. Flow sensor is not turning due to blockage or damage.
3. Sensor wiring is loose or incorrect.
Press RIGHT key to start AutoCAL procedure again.
Make sure that the À ow rate entered is accurate.
1. Correct piping layout to provide more straight pipe upstream
of sensor.
2. Set the SPEED to higher setting to average out the
À uctuations caused by piping conditions. (see Speed,
section 14)
Replace battery #1, then replace battery #2.
