Section 10. Troubleshooting Charging Regulator with Solar-Panel Test Disconnect any wires attached to the 12V and G (ground) terminals on the PS100 or CH100 charging regulator. Unplug any batteries. Connect the solar panel to the two CHG terminals. Polarity of inputs does not matter. Only the solar panel should be connected. Set the charging-regulator power switch to OFF. NOTE This test assumes the solar panel has an unregulated output. Solar Panel Test Set a voltmeter to measure DC voltage. Measure solar panel output across the two solar-panel leads by placing a voltmeter lead on one CHG terminal, and the other lead on the other CHG terminal. Is the No output 17 to 22 Vdc? Yes Remove the solar-panel leads from the charging circuit. Measure solar-panel output across the two leads. Is the output > 0 Vdc? No Yes The solar panel is damaged and should be repaired or replaced. Is the voltage ≥ 17 Vdc? There may not be enough sunlight to perform the test, or the solar panel is No damaged. Yes 5-kΩ Load Test 1) Place a 5-kΩ resistor between a 12V terminal and a G (ground) terminal on the charging regulator. 2) Switch the power switch to ON. 3) Measure the DC voltage across the resistor. Is the measured voltage 13.3 to 14.1 V? Yes Reconnect the power source (transformer / solar panel) to the CHG terminals on the charging regulator. Yes Measure the voltage between the two No CHG terminals. Is the voltage ≥ 17 Vdc / Vac? Measure the voltage between the two pins in a battery-connection receptacle. Is the voltage 10.0 to 15.5 Vdc? No No Yes 50-Ω Load Test 1) Switch the power switch to OFF. 2) Disconnect the power source (transformer / solar panel). 3) Remove the 5-kΩ resistor 4) Place a 50-Ω, 1-Watt resistor between a 12V terminal and a G (ground) terminal on the charging regulator. 5) Reconnect the power source and then switch the power switch to ON. 7) Measure the voltage across the ends of the resistor. Is the voltage 13.0 to 14.0 Vdc (13.3 if circuit just adjusted)? 8) Switch the power switch to OFF. NOTE The resistor will get HOT in just a few seconds. After No measuring the voltage, switch the power switch to OFF and allow the resistor to cool before removing it. Yes See Adjusting Charging Voltage (p. 440) to calibrate the charging regulator, or return the charging regulator to Campbell Scientific for calibration. With the charging regulator still under load, measure the voltage between the two CHG terminals. Is the voltage > 15.5 Vdc? Yes No Obtain Repair Authorization The charging regulator is damaged and should be repaired or replaced. Test Completed The charger is functioning properly. Remove the 50-Ω resistor. There may not be enough sunlight to perform the test. 438

Charging Regulator with Solar-Panel Test

Disconnect any wires attached to the 12V and G (ground) terminals on the PS100 or CH100 charging regulator.

Unplug any batteries.

Connect the solar panel to the two

CHG terminals.

Polarity of inputs does not matter.

Only the solar panel should be connected.

Set the charging-regulator power switch to OFF.

NOTE

This test assumes the solar panel has an unregulated output.

Solar Panel Test

Set a voltmeter to measure DC voltage.

Measure solar panel output

across the two solar-panel leads by placing a voltmeter lead on one

CHG terminal, and the other lead on the other CHG terminal.

Is the

output 17 to 22 Vdc?

Remove the solar-panel leads from the

charging circuit.

Measure solar-panel

output across the two leads.

Is the

output > 0 Vdc?

The solar panel is damaged

and should be repaired or

replaced.

Yes

Is the voltage

≥

17 Vdc?

There may not be enough

sunlight to perform the test,

or the solar panel is

damaged.

Yes

Reconnect the power source

(transformer / solar panel) to the CHG

terminals on the charging regulator.

Measure the voltage between the two

CHG terminals.

Is the voltage

≥

17 Vdc

/ Vac?

5-k

Ω

Load Test

1) Place a 5-k

Ω

resistor between a 12V terminal and a G (ground)

terminal on the charging regulator.

2) Switch the power switch to ON.

3) Measure the DC voltage across the resistor.

Is the measured voltage 13.3 to 14.1 V?

Measure the voltage between the two

pins in a battery-connection receptacle.

Is the voltage 10.0 to 15.5 Vdc?

Yes

See

Adjusting Charging Voltage

(p.

440)

to calibrate the charging regulator,

or return the charging regulator to

Campbell Scientific for calibration.

50-

Ω

Load Test

1) Switch the power switch to

OFF

2) Disconnect the power source (transformer / solar panel).

3) Remove the 5-k

Ω

resistor

4) Place a 50-

Ω

, 1-Watt resistor between a

12V

terminal and a

(ground) terminal on the charging regulator.

5) Reconnect the power source and then switch the power switch to

7) Measure the voltage across the ends of the resistor.

Is the voltage 13.0 to 14.0 Vdc (13.3 if circuit just adjusted)?

8) Switch the power switch to

OFF

NOTE

The resistor will get HOT in just a few seconds.

After

measuring the voltage, switch the power switch to

OFF

and allow

the resistor to cool before removing it.

With the charging regulator still under

load, measure the voltage between the

two CHG terminals.

Is the voltage >

15.5 Vdc?

Yes

Obtain Repair

Authorization

The charging regulator is

damaged and should be

repaired or replaced.

Yes

Test Completed

The charger is functioning

properly.

Remove the 50-

Ω

resistor.

There may not be enough sunlight to

perform the test.
