Go to ‘Hardware Index’

Power Supply of the GSR.

All LEDs are off after pressing the power button.

1º- Check that the power supply connection point has a correct and stable voltage, without automatic or accidental disconnections.

• If the power supply is connected to a point in the electric installation that has automatic power cuts, it will cause the device to operate on battery, and it will turn off when the battery is exhausted, such as in the automatic cabin light shutdown, or in some private homes or public buildings that disconnect the electric installation when not in use or when the building is closed.

2º- Check that the device is on and the power supply is connected.

• Make sure the power supply is connected to the GSR’s power input and the power button is pressed.

3º- Check that the power supply is connected.

• Ensure that the power supply is connected to a correctly functioning electrical connection point.

4º- Check that the power supply connection point has voltage.

• Verify with a multimeter that the electrical connection point of the power supply has a voltage of 230V AC.

5º- Check the power supply output voltage.

• The output voltage of the power supply should be 18V DC. If the output voltage is not correct, contact Support for replacement of the power supply.

6º- Tighten the power supply connector and check that it makes good contact with the GSR input.

• If the issue is due to connector wear, contact Support for replacement of the power supply.
• If the issue is due to the GSR input connector, contact Support for replacement of the GSR.

7º- Connect the power cable and check if the red battery LED blinks.

• If the GSR has been without a power source for an extended period, the battery will have discharged. It will recharge automatically when connected to a power supply for a sufficient amount of time.
• When power is restored and the GSR is turned on with a discharged battery, the charging process will begin.
• While the battery charge is below 5%, the battery LED will remain solid red.
• If the battery charge is between 5% and 10%, the battery LED will flash.
• The battery LED will turn off once the charge level exceeds 10%.
• Allow the GSR to charge for approximately 20 minutes. Afterwards, disconnect it from the power supply and verify that it remains powered on.
• If the battery fails to keep the GSR operational, proceed with a battery replacement.

When there is a power outage, the GSR does not reach 1 hour of autonomy.

1º- Confirm that the GSR is being correctly powered.

• There may be an issue with the power supply, causing the battery to discharge.

2º- Keep the GSR connected to an external power supply for approximately 2 hours to allow the battery to reach full charge.

• The battery should be charged and power the device for more than 2 hours.

3º- Confirm that the device is charging: Request a report via SMS.

• If the battery percentage (SOC) is not high or the charge status indicator (CRATE) does not show charging, it could indicate a malfunction of the GSR.

• Send:
  SMS: PinCode,C:rp
  Default: 12345,C:rp

Response: [ {“id”:“gsr.a8504222220b”, “hw_version”:“1”,“sw_version:1.13.0”, “max17048.soc”: 91.8, “max17048.v”: 8. “max17048.crate”: 0, “modem.csq”: 19, “modem.cops”: 7, “modem.icc”:“8934111111148059255”, “modem.imei”:“867582222222236”,“n4m.online”: true} ]

max17048.soc: Indicates the battery charge percentage.
max17048.v: Indicates the battery output voltage.
max17048.crate: Indicates the charge status of the battery management.
A negative value indicates that the battery is discharging (No power supply).
A positive value indicates that the battery is charging.
If the value is ‘0’, it means that the battery is in “rest”, neither charging nor discharging.

• If the power supply is adequate and the battery does not charge, contact Support for replacement of the GSR.
