3. After both the LMV52 and the VFD are wired and configured properly,
then the standardization can be performed.
As was mentioned earlier, this is when the LMV52 "learns" the specific
characteristics of VFD / motor that is connected to.
This procedure is automatic, but does have some prerequisites. These are:
a. If working on an un-configured LMV52, ensure that:
The pre-purge position of the air actuator should be close to,
(within +/- 15 degrees) to the expected high fire air actuator position.
b. Make sure The LMV52 safety loop is energized (closed),
including the burner flange section.
The safety loop can be open in Phase 12 and not cause an alarm,
but the LMV52 will not Standardize if the safety loop is open.
Standardization is possible even while the LMV52 is in an alarm condition,
as long as the alarm is not due to an open safety loop.
c. Under VSD Module>Configuration>Speed>Standardization, select activate.
The air actuator should open to the purge position and the VFD / blower
motor should ramp up and then ramp back down.
After the ramp down is complete, Standardization returns to deactivated.
d. Parameter StandardizedSP should read close to full speed RPM of the
blower motor.
For most 3600 RPM blowers, it should be 3500 +/- 100 RPM.
e. If the LMV52 does not have O2 trim,
set the air actuator back to activated instead of air influen.
4.
The LMV52 VSD control set-up is now complete, and the blower speed can be set:
at each special position, and
at each fuel air ratio control point. (Combustion curve)
LMV5 QSG Rev 4
the Burner ID is set,
the fuel train is defined,
the actuators are addressed,
actuator DirectionRot (ation) are correct and
that all the actuator special positions are set.
