4. EXCESSIVE FLOW: if the flow rate exceeds the motor HP
capacity, the electric motor will draw excessive amps. This
is a result of the process loop’s ability to flow water at a
greater rate than can be provided by the pump. This
eventually results in tripping the thermal motor overload
relay (overload relays open) and the unit will shut down
and illuminate red the LOW FLOW light on the display.
a. If an excessive flow
situation is
encountered and
the motor overload
circuit has tripped,
the operator must
manually reset the
overload relay
(figure 3.2I) before
operations can
continue. This is
done by opening
the electrical panel
cover, identifying the reset lever on the overload
relay, and pushing the reset lever “in” until the
overloads are reset (evidenced by a “clicking”
sound as the overloads reset).
4. The instrument displays the
process flow rate in the
FLOW display window
(figure 3.2J). To adjust the
process flow rate, continue
with
step 5 .
5. To set the process flow rate
via the digital flow meter:
a. Determine the
pump’s HP rating
and maximum
GPM flow rate.
Standard models
are listed in the
specifications chart
(figure 3.2K). The
displayed flow rate
should not exceed
the maximum flow
rate during
operations. If the
maximum flow rate
is exceeded, a
possible overload
