10.11 Setup > Inputs/Output > Output #1 (or Output #2 or
Output #3)
Output #1, Output #2 or Output #3 can operate independently as a frequency, totalizer pulse, direction
status or alarm status output In the SETUP > INPUT/OUTPUTS > OUTPUT #1 (OR OUTPUT #2 OR
OUTPUT #3) > MODE menu, select the MODE of operation Then go to the PARAMETERS menu to
set up the operation for that MODE
Output #3 is available on the energy unit only An asterisk (*) indicates the parameter default

frequency that corresponds to maximum
frequency flow rate or velocity Can be negative
to indicate reverse flow The units of Maximum

SETUP > MEASUREMENTS > FLOW UNITS
Example 1:
For a system that only has flow in one direction,
the maximum flow rate is 100 gal/min, and the
corresponding maximum frequency is 2000 Hz,
set up the parameters to:

Maximum Frequency
2000 Hz
Example 2:
For a system that flow is bidirectional, the flow
rate ranges from -100 gal/min to 100 gal/min
and the frequency at 100 gal/min is 2000 Hz,
set up the parameters to:
