BaseStation 3200 Advanced Irrigation Controller Manual

• After the short has been diagnosed as either damage to the wire or a faulty device, repair or

replace it.

• Reconnect components on the repaired two-wire segment. Verify that that adding these

components does not cause additional failures.

• Connect other two-wire segments, verifying correct operation as each is connected.

Diagnosing a Circuit Board Issue

1. Disconnect the two-wire from the controller.

2. Check the controller to determine whether the Over Current message redisplays.

3. If the message redisplays, you have confirmed a circuit board issue. Contact Baseline Support

at 866-294-5847.

Troubleshooting with a Milliamp Clamp Meter

1. Wire a solenoid in line with the red wire of the two-wire

path right after the controller as illustrated here.

2. Set the two-wire to always on. Refer to Setting the

Two-Wire to Always On on page 81.

3. Use the milliamp clamp meter to take a milliamps ac

reading on the red wire (two-wire) that is connected to

the controller. Write down this reading, which will be

referred to as the “over-current reading.”

4. Go to the first wire splice and use the milliamp clamp

meter to take a reading on all red wires (two-wire). As you

take the readings, look for a number that is close to the

over-current reading.

Note: The reading does not have to be identical.

5. Continue testing all red wires on the two-wire path,

looking for the over-current reading until you isolate a

wire segment or device that is generating that number.

6. Remove the suspected device from the two-wire path, and then check the controller again.

7. Perform one of the following actions:

 If the Over Current message persists, check the two-wire in that stretch for damage.

 If the Over Current message goes away, remove the two-wire path and connect the

device directly to the controller. If the Over Current message returns, the device is faulty

and will need to be replaced.
