Installing the Electrical Conduit:
Knockout holes for connecting the electrical conduits are located at the top left and right of the Wall Box.
•
Connect rigid conduit for the required 120-vac electrical service.
•
Connect conduit for the operating power to the upper left top of the enclosure at the junction box.
•
Connect conduit for the operating power for the output to the upper right top of the enclosure.
Wiring the Unit:
Important!
Verify that the electrical supply is disconnected prior to connecting wiring to the DLA Controller.
To wire the Controller:
1.
Remove the junction box cover.
2.
Make final connections to the 120-vac electrical service to wiring within the junction box. Verify that line wiring
(Black), neutral (White), and ground wire (Green) are correctly connected.
Minimum recommended wire size is 14 AWG.
3.
Replace the junction box cover before activating or testing the unit.
Optional Input Control circuit:
24-vac/vdc active OFF inputs can be connected at CON 4-B and 4-C (JP 11 determines 4-C usage). Refer to jumper
configuration chart Make connection from only one source at each connector terminal.
Remote Panic Input Connection:
Flow Sensors and/or moisture sensors providing dry-contact outputs are connected to the PCB at CON 4-a. Flow Sensors
should have the time delay function set to the approximate time needed by ice maker machines to cycle so that this process
will not inadvertently trip the Unit to OFF. An optional Remote Panic Button can also be connected at the CON 4-A
Optional Panic Output Terminal:
A configurable Panic output is activated at CON 5. See configuration chart and location of this connector on page 5.
Connection of the Wall Panel Plug:
The Unit is equipped with a 9 pin d-sub connector
•
Turn counter-clockwise the two retaining clips at the top of the Panel, and open.
•
Insert plug onto circuit header on PCB.
•
Turn Power
ON
.
•
Close the panel and lock.
CAUTION!
Do not install the panel until all wall finishes are complete. Verify that the plug is configured correctly.
Incorrect insertion will prevent operation of unit.
Important!
All local codes must be followed when installing this unit and when connecting the conduit to the service panel and
making wiring connections. Do not install wiring or cable for integrated systems, remote panic assemblies or other
interface wiring within conduit for either 24-vac control or 120-vac line voltage. Each wiring system including
outputs should be housed in independent conduit and not bundled with wiring for other systems. Failure to comply
with these wiring specifics may create transient voltage at the pc board and cause system malfunction and/or failure.
Operation of the Unit:
Engage the OPERATE Switch. The circuit will activate and the panel Green LED above that switch will illuminate to
indicate that the Unit is actively monitoring the water flow within the residence. To turn OFF the Monitoring function of the
unit, engage or the OPERATE Switch to the OFF position. Once the Unit is in the OFF mode, it will be necessary to re-
engage the SERVICE ON switch in order to reactivate the service.
The Green LED above the SERVICE ON Switch will illuminate if the water service solenoid is open.
Once in the Panic Mode the SERVICE Switch must be engaged in order to reactivate service. All Input Signals must be
withdrawn prior to reactivation. If it is desired to have the water service valve ON without re-activating the monitoring
function of the unit, then engage only the SERVICE Switch.
