Precision Trading 60 R3.0 operating instructions Float Voltage, Peak Voltage

Operator Manual, Supercharger 60 R3.0

8.12FLOAT VOLTAGE:

8.12.1.Settings:

8.12.1.1.Set the Voltage Control Selector to Float

8.12.1.2.Set the Current Selectors to zero.

8.12.2.Connect the Battery Cable to the battery and note the battery voltage.

8.12.3.Using the chart in figure 3 (page 19) find in the FLOAT column the closest higher voltage (by at least 1V) to the observed voltage on the battery. Set the cell selector to the value indicated in the Cell Selector column.

8.12.4.Start the Charger-Analyzer in Single Rate an advance the Topping current to 1A

8.12.5.Observe that the current will start to be reduced as the battery voltage approaches the corresponding float voltage.

8.12.6.Example: for 24V measured on the battery set the cell selector to 22. This will result in a float voltage of 25.6. As long at the voltage at the battery is less than 25.1, the charge current will be as programmed. As the voltage rises towards the expected 25.6, the current will start to decrease and will settle on a value of current to maintain the battery at 25.6

8.12.7.Depending on the condition of the battery, a charge current higher than the initial 1A may be required for the battery to rise to the expected float voltage. Conversely, if the voltage rises too fast it will be necessary to select the next higher reading (23 for 26.8V) and /or a lower charge current.

8.12.8.Verify that the Charger-Analyzer maintains the battery at the expected voltage ±0.2AV

8.13PEAK VOLTAGE:

8.13.1.Settings:

8.13.1.1.Set the Voltage Control Mode to Peak.

8.13.1.2.Set both current selectors to zero

8.13.1.3.Program for a nominal battery voltage of 24V on the cell selector (setting = 24).

8.13.2.Connect the CAL-100 Calibrator or a power supply (capable of producing at least 35V with very little current) in place of the battery.

8.13.3.Set the calibrator/power supply to 28.5V

8.13.4.Start the Charger-Analyzer in Dual rate. The current will rise to the programmed value.

8.13.5.Increase the power supply/calibrator towards 29.4V. The Charger-Analyzer will switch from Main to Topping at a battery voltage of 29.4V ±0.5V.

8.13.6.Return the Voltage Control Mode to CC.
