5.3 TROUBLESHOOTING GUIDE FOR SYSTEM-10-P1 BTU MEASUREMENT SYSTEM

NOTE: Also refer to the COMMISSIONING GUIDE located on the preceding pages.

REPORTED PROBLEM POSSIBLE SOLUTIONS

For turbine meters -

No ow signal/ energy rate

(while hydronic system is

active)

• Verify 24 VDC supply voltage to the ow meter.

• For insertion meters, verify the ow meter is correctly inserted into

the pipe (using depth gage).

• For insertion meters, verify that the ow meter electronics enclosure

is parallel with the pipe.

• Verify correct wiring to the ow meter (see wiring diagram).

• For turbine meters, check turbine(s) for clogging due to debris.

• If none of the above, check hydronic system to ensure that ow is

really present in the line.

• NOTE: Flow meter function cannot be veried by blowing on the

turbine(s). The sensing system requires a conductive liquid to

operate. You can test it by swirling it around in a bucket of water

and looking for the ow indicator LED to ash at the System-10.

Displayed ow rate too high

or too low

• Verify pipe size. Contact ONICON if pipe size is different from

calibration tag.

• For insertion meters, verify that meter is inserted correctly into the

pipe (using depth gage).

• For insertion meters, verify that the ow meter electronics enclosure

is parallel with the pipe.

• For dual turbine meters, conrm that both turbines produce pulses.

• For turbine meters, check turbine(s) for debris.

• Verify supply voltages (to BTU meter and ow meter).

Displayed temperature(s) too

high or too low vs. expected

values

• Verify wiring to temperature sensor(s), including polarity.

• Verify that thermowells are inserted into the ow stream and

that the temperature sensors are completely inserted into the

thermowells.

Data not available at the

control system

(Device ofine)

• Verify that the device address has been correctly programmed into

the System-10-P1.

• Verify that the System-10-P1 has been properly characterized in the

eld panel.

• Press and hold switch S-1 for two seconds.

Control system displays

incorrect multipliers and/or

units vs. displayed

values

• Verify that the units and multipliers shown on the System-10-P1

display agree with the values shown on the Floor Level Network.

• The device must be re-characterized in the eld panel whenever the

System-10-P1 units or multipliers are changed.
