DRYDEN AQUA 90022 Manual de instruções
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.
