In the previous step you should have checked that the wiring is correct by measuring the control cable resistances.
The following test provides further confidence that everything is working as intended.
•
Before beginning these steps read through the OptimizIR Operators Manual so you are familiar with the operation of
the controller. Then read through the following section before performing any of the steps below.
•
You will also need a multimeter to test for continuity. The jumper cables and fiberglass poles should not be installed
on the antenna at this time.
Test Procedure
Step 1:
Connect the control cable to the SDA 2000 OptimizIR controller and then connect the power supply to the con-
troller.
Step 2:
The display should read “Elements Home”. If not, push the retract button. After the tuning LED stops flashing it
should now read “Elements Home”. If “
check fault
” appears in the top right corner of the display, stop and address the
fault before proceeding.
Step 3:
Press the setup button and scroll
to “Motors Test”
Step 4:
Test each motor by extending and retracting it (using out-in or cycle). Make sure that the correct motor re-
sponds, for example, REF signals the Reflector, DVR signals the Driven element and so on. If the wrong motor re-
sponds, a plug may be switched in the junction box or the antenna may be miswired.
Note that the copper tape will
only extend 4 inches and that it
won’t stick out of the CPVC stub on both sides of the EHU.
Step 5:
Exit the motors test menu and select the
“Relays Test”
Step 6:
Open all relays. Using a multimeter check for continuity between the Coax IN and OUT 3 on the coax switch
(probe the center pin of both conductors). Make sure that there is no connection between IN and OUT 1 or OUT 2.
Step 7:
Close relay 2. Check for continuity between the Coax IN and OUT 1. Make sure that there is no connection be-
tween IN and OUT 2 or OUT 3.
Step 8:
Close relay 3. Check for continuity between the Coax IN and OUT 2. Make sure that there is no connection be-
tween IN and OUT 1 or OUT 3.
Step 9:
Exit the relay test menu. Power off the controller and disconnect the power and control cable.
