Determines the type of actuators being used.
Index 00 = fuel actuator. Index 01 = air actuator
0 = SQM33.5... actuators (27 in-lb, 5 sec / 90°)
1 = Not used
2 = SQM33.7... actuators (90 in-lb, 17 sec / 90°)
Note: The type of air actuator being used can only be set under parameter 613 and is not displayed under
parameter 614.
This starts the standardization process for the VSD. Set parameter to 1 and press Enter to begin the
standardization process. The air damper will open to the prepurge position, and then the VSD will ramp up
and then back down. The air damper will then close. During this time, the LMV3 will correlate a speed
signal to the peak motor RPM. If the value changes back to 0, the standardization process was completed
successfully. If the value changes to a negative number, see error code 82 for the cause of the failure.
This displays the standardized blower motor speed (in RPM) corresponding to a 95% speed signal (if
parameter 661 is set to 1, typically VFD) or a 98% speed signal (if parameter 661 is set to 0, typically PWM).
This is automatically recorded when the VSD is standardized (see parameter 641).
Index 00 = recorded standardized speed in RPM
Index 01 = recorded standardized speed in RPM (redundant for monitoring)
This sets if the speed signal from the motor is asymmetric or symmetric. If using a VFD and 3-phase motor
with a speed wheel, this must be set for asymmetric. Most brushless DC blowers have a symmetric pulsed
output.
0 = asymmetric
1 = symmetric
This sets the expected number of pulses per motor revolution. Set for 3 if using the standard 3-finger speed
wheel or 6 if using the 6-finger speed wheel. Most brushless DC blowers output 2 or 3 pulses per
revolution.
Determines the range of the analog output from terminal X74 (pins 2 and 3). If using a VSD (parameter 542
= 1) with an analog input, this output sends the control signal to the VFD / PWM blower. Otherwise, this
output acts as the load output. Setting of this parameter does not affect the separate PWM output on
terminal X64 pin 3.
0 = 0-10 VDC
1 = 2-10 VDC
2 = 0/2-10 VDC
