52. The “Supply Air High Limit” field, below “SA High Limit Override” is
used to set a supply air high temperature limit above which FanMaster
will run the supply air fan at full speed (100%) to avoid overheating the
heating system. Press the value next to “Supply Air High Limit” and
enter the supply air high temperature limit at which FanMaster will
command the supply fan to run at full speed.
53. Press “Next”. If you have installed an evaluation unit, the Data
Collection screen displays - continue with step
installed, the Proof of Flow Setup screen displays - continue with step
below.
54. The Proof of Flow Setup screen is used to:
–
Verify that the supply air fan (and return air fan, if installed) is
rotating in the correct direction. During the test, the fan(s) will run.
If the fan(s) is not turning in the proper direction, you must reverse
any two motor leads.
–
Set up the “Proof of Running” output. The existing proof of flow
sensor (flow switch or pressure sensor) may not provide accurate
proof of flow at a reduced fan speed. FanMaster will detect flow by
monitoring the torque current required by the supply fan at the
minimum speed. If the supply fan drive is not delivering 50% of this
current threshold, the proof of flow output turns off. The test allows
the system to capture the 50% threshold value by monitoring the
current supplied to the motor at the minimum fan speed.
Read and complete the tasks in steps 1…4 on this screen. Once the test
has been initiated, a message box displays to indicate that the test is in
progress. You can touch “Press to Abort Test Stop Fan” at any time to
stop the test and shut down the fan(s).
If the drive(s) starts and stops (does not run continuously), verify all
communication wiring between the drive(s) and FanMaster and that the
communication cables are not installed near the power cables.
