Set Point is the speed at which the blower(s)
shall run when not in humidity control. This value
corresponds to the maximum frequency setup in
the VFD (typically 60Hz).
Minimum Output is the minimum speed
proportional to the VFD minimum frequency
that the blower is allowed to run when in
humidity control. Because the minimum
frequency in the VFD is typically setup to 45Hz, it
means that at 0% the blower will be running at
45Hz. This value can be changed if a higher
minimum frequency is desired without the need
to re-configure the VFD. For example, if the user
wants the new minimum speed to be 50Hz, then
Minimum Output shall be 33.3%.
Formula:
Minimum Output %
= Hz increase divided by (Maximum
Frequency minus Minimum Frequency)
times 100
= (5/(60-45))*100
=33.3

Alarms
Alarms are intended to protect the equipment
and the people working on it. Some alarms stop
the machine entirely while others are just
warnings to the operator.
When an alarm is active, the ALARM button will
blink RED.
Press the ALARM button to enter the alarm
loop.
As you scroll DOWN or UP using the buttons,
you will see all active alarms.
The last screen is a shortcut for the ALARM LOG
loop. See ALARM HISTORY loop section for the
explanation.
Press the ALARM button twice to clear the
alarms. If the alarm is still active, you will
continue to see the alarm. If the alarm
condition no longer exists and the alarms were
successfully cleared out, you will the message
“No active alarm” as shown below and when
exiting the Alarm loop the ALARM button stops
blinking.
