auxiliary relay (optional kit) cont.
Installation (external)
The Auxiliary Relay comprises two sets of double pole / double throw dry contacts. Both sets of contacts will operate at
the same programmed fl ow rate as set in the ‘Advanced Setup’ section on page 14. Each of the two sets of contacts has
a normally open and a normally closed relay. The ‘normal state’ is the condition that the contacts are in before they are
activated when the coil is energized by the programming value. Please refer to the Auxiliary Relay Connection Diagram (Fig.
2.9) on page 10.
Using the cable spade connectors provided, connect the external wiring to the required Auxiliary Relay outputs. For example,
if the Heater requires a contact closure to operate, connect the heater enabled circuit to either terminals 4 and 2, or 8 and
6. Both of these are normally open contacts that will close when the relay coil is energized by the setting applied in the
‘Advanced Setup’ section on page 14.

display features
The AcuFlow Digital Display comprises certain standard features as well as user-defi ned parameters / adjustments. Standard
features include a Digital and Bar Graph reading of the measured fl ow rate. The user has the option to program the Unit
of Measurement to be displayed in either US GPM (default), LPM or M
3
/hour. The patent pending feature that displays the
Turnover Rate is activated by the user during programming. The Display’s format can also be programmed by the user to
change its appearance under prescribed conditions, e.g., fl ash above or below a certain fl ow rate. Refer to the ‘Advanced
Setup’ section for more information on how to take advantage of this functionality.
