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 flow 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.

3.0) 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.

14. Display features

The FlowVis Digital Display comprises certain standard features as well as user-defined parameters / adjustments. Standard

features include a Digital and Bar Graph reading of the measured flow rate. The user has the option to program the Unit

of Measurement to be displayed in either US GPM (default), LPM or M

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., flash above or below a certain flow rate. Refer to the 'Advanced

Setup' section for more information on how to take advantage of this functionality.
