11 – TROUBLESHOOTING
The BaseStation 3200 has built-in features for testing zones, valves, biCoders and biSensors. These tests help you
isolate and identify components and devices that are not working properly so you know what needs to be
repaired.
Testing Zones, Valves, and biCoders
When you test a zone, the controller verifies the communication between the controller and the valve biCoder.
The controller activates the solenoid and measures the current and voltage. It deactivates the solenoid, and
measures the voltage drop between the controller and the valve biCoder.
1. Turn the dial to the Self-Test position.
2. Press the NEXT or PREV button to select Test Zone (Valve), and then
press the ENTR button.
3. Press the + or – button to select the zone number that you want to
test.
4. Press the ENTR button to test the zone
The valve will activate for less than a second to measure the voltage
and current through the valve solenoid. This test will return the
solenoid current and the status of the valve.
5. When you have finished viewing the test results, return the dial to the Auto Run position.
Refer to the following table for possible self-test statuses along with causes and suggestions for resolving the
issues.
Self-test status Cause/Action
Open circuit • Wire connection between the valve biCoder and the valve solenoid is broken –
repair wire connections.
• Valve solenoid is broken – replace solenoid.
Short circuit • Wire connection between the valve biCoder and the valve solenoid is shorted
together – repair wire connections.
• Valve solenoid is broken – replace solenoid.
No response • Two-wire connection to the valve biCoder is broken – repair wire and connections
to the valve biCoder.
• Two-wire voltage loss is too high – check other devices in same vicinity for high
two-wire voltage loss – repair high resistance connections between controller and
devices.
• Valve biCoder is damaged – remove biCoder and move it directly to the controller
to test its ability to communicate.
