Do you have correspondence issues or would you say you are uncertain about the measures? Is it conceivable your capacity supply by sun powered board is the reason? How would you know whether this originates from your sun powered board power supply?
As we referenced in a blog entry “6 stages to decide whether your datalogger needs adjusting”, a significant number of the information obtaining framework disappointments are brought about by control issues. incorporate issues with the batteries, charge controller or charging source.In this article we will see seven stages to assist you with seeing whether your sun oriented power supply has an issue.
Before you start, you should have the accompanying apparatuses:
• A decent advanced multimeter (voltmeter and ammeter)
• A little level screwdriver (2.5 mm)
• A couple of wire strippers
The greater part of the means depicted here include present or nonstop voltages (DC) on various pieces of your capacity framework. To gauge DC voltage, set your voltmeter to the 20 VDC extend with the red shading test on the mAVΩ terminal and the dark test on the COM terminal. During the test, you position the red test at one of the accompanying: the terminal square screw checked 12V, +, or the uncovered finish of a red wire. Then again, you position the dark test to one of them: the screw of the terminal square recognized G, – , or the exposed finish of a dark wire.
1 – Test of the live power station
You can check if the datalogger is controlled from the power supply by following these means:
- Measure the voltage at the power input terminals of the datalogger. Most Campbell Scientific dataloggers have a green connector, which associates with an attachment stamped POWER IN.
o If your datalogger doesn’t have the two-terminal connector, you should screen the datalogger’s battery leads and play out the estimations there.
- Position the dark test at the screw terminal checked G or Battery – .
- Position the red test at the screw terminal checked 12V or Battery +.
o If the read voltage is more prominent than 11V, the test is fruitful, and your datalogger gets enough power.
o If the voltage read is under 11V, there is most likely an issue with your capacity supply. See the accompanying strides to figure out where the issue is.
2 – Make sure the power supply is turned on
You might be amazed how basic it is for somebody to mood killer the intensity of a datalogger under any conditions, and afterward neglect to walk out on later. (For more data regarding this matter, read the blog article “How to investigate information obtaining frameworks in great conditions.”)
• If the power switch is in the Off position, move it to the On position, and rehash step # 1.
• If the power switch is now in the On position, go to step # 3.
3 – Measure the voltage of the power supply
In the event that you take a gander at your eating regimen, do you see the different terminals named 12V and G? Simply pick one of each kind of terminal to utilize.
Measure the voltage between terminals 12 volts and G of your capacity supply. In the event that you measure more than 11V on the charge controller yet under 11V on the datalogger, check the wires that interface them.
• If you discover a wire that isn’t associated appropriately, turn off the power before reconnecting.
• If you discover great electrical associations on the wires, go to stage 4.
4 – Check the battery voltage
At this phase of the test, your estimations give under 11 V at once for the datalogger and the power supply. The subsequent stage is to test the battery voltage with the dark test on the negative (- ) terminal and the red test on the positive (+) terminal of your battery.
• If the voltage read is more noteworthy than 11V, the battery is OK, yet the power supply must be returned for fix. Contact Campbell Scientific to acquire a Returned Material Authorization (RMA) number.
• If the voltage read is under 11 V, disengage the battery.
5 – Check the voltage of the power supply, without associating the battery,
With the battery disengaged, you can check the voltage of the power supply by following stage 3 as a guide.
• If the voltage estimated between terminals 12V and G gives an estimation of 13 to 14 V, the battery should be supplanted.
Presently check the voltage on both charging terminals of the power supply. These are marked CHG, yet it doesn’t make a difference what shading test you put on the terminal square.
• If the voltage on the charging terminals shows in excess of 17 V, the power supply must be returned for fix. Contact Campbell Scientific for a Returned Material Authorization (RMA).
6 – Measuring the voltage on the sun powered board
Presently it’s a great opportunity to unplug the sun based board from the power supply. You can quantify the board voltage by contacting the tests at the parts of the bargains wires of the board. Try to do this test during the day when the sun oriented board isn’t shrouded or in the shade. With the red test contact the red wire, with the dark test contact the dark wire and measure the voltage.
• If the voltage on the sun oriented board demonstrates under 17 V when the board is in direct daylight, the sunlight based board must be supplanted.
7 – Test the sun oriented board current
For this last advance, set your multimeter or ammeter to gauge the amps with the goal that you can quantify the present originating from the sun based board.
Tip: To abstain from starting, we propose that you briefly spread the sun oriented board with a material or something comparable.
Measure the current by following these means:
- Move the multimeter’s red lead to terminal 10 Acc, and pick the 10 A range.
- Interface the red test to the red (positive) wire of the sun based board.
- Interface the dark test to the dark (negative) wire of the sun based board.
- With the tests associated, expel the covering situated on the sun based board, and uncover the sun powered board to daylight
- Contingent upon the hour of day and the climate, your estimation will presumably be not exactly the most extreme showed, however it should be near the worth that is adjusted to the size of your sun powered board.
o When the board is in the sun, if the present estimation from the sun oriented board is near the most extreme yield current, however the voltage at terminals 12V and G from step No. 5 is under 13 or 14 V , the power supply must be returned for fix. Contact Campbell Scientific for a Return Authorization (RMA).
o If the present estimation from the sun oriented board is unreasonable, either the sun based board or the sun based board association wires to the power supply might be harmed.
Trial of the dataloggers with a base including a power supply
Some Campbell Scientific dataloggers have their capacity supply coordinated into a square with a battery-powered battery. For this kind of information lumberjack, before you can perform steps # 5 and # 6, you should detach the battery by isolating the module base from the datalogger. (For more subtleties, see the manual of your estimation station.)
