PROGRAMMING PARAMETERS
PROGRAMMING THE WHEEL MOTOR VFD:
NOTE:
For most V1000 parameters, the drive must be in a
STOP
condition while programming.
1)
Press
ESC
key until left-most part of drive’s display
shows
F
.
DRV
LED will also be lit.
2)
Press
DOWN
arrow twice to display
PAr
then press
ENTER
key. (Parameters are now accessible)
3)
Using
UP/DOWN/RIGHT ARROWS
, select
parameters to be read and/or changed starting
with A1-01.
4)
If required, use
RIGHT ARROW
or
ENTER
key to
scroll to right-most digits of parameter name.
Digits will flash.
5)
Press
ENTER
key to read value.
6)
Using
UP/DOWN/RIGHT ARROWS
, set desired
value then press
ENTER
key to store value. Drive
will accept value,
if valid, then re-display parameter number (i.e. B1-
01, C1-02, etc.)).
7)
Repeat
STEPS 3 - 6
to program remaining
parameters per application requirements.
8)
When complete, press
ESC
key until left-most part
of drive’s display shows
F
.
DRV
LED will also be lit.
V1000 DRIVE IS NOW READY TO RUN.
SEQUENCE OF OPERATION
Refer to the Unit Submittal for a detailed sequence of
operation, performance, and wiring schematic.
The typical sequence of operation is that upon a call
for dehumidification, the pre-cooling coil is active and
cools the process air to the temperature shown in the
submittal. The dehumidification wheel bypass damper
modulates partially closed to produce the correct
proportion of process air through the wheel and bypass.
The regeneration heat source modulates to maintain the
humidity setpoint. The process and regen fans modulate
to maintain their supply CFM setpoints.
