Observe Mode (continued)
The OBSERVE mode uses the three upper
areas of the VZ-7’s control plate to display
operation information:
The SETTINGS and OPTIONS area indicates
which lines are currently active to the motor.
The DIGITAL DISPLAY area alternates back
and forth every 5 seconds or so with the cal-
culated RPM and programmed CFM that the
motor is pumping. This display may take up
to 30 seconds to stabilize after the motor has
reached a constant speed. Note: not every
motor is programmed with this feature.
The 4-LED TAP section has tri-color LED’s
that indicate the 4 tap settings that can send
set-up information to the motor. Their status
is reported as: 1) No color means no option
selected on this tap. 2) Green color means
the first option is selected. 3) Red color means
the second option is selected, and 4) Yellow
color means that both options are selected.
