Battery Voltage & Current Monitoring - Ametek ASCEND Series Operation Manual

Ascend Single Phase Charger Operation Manual
To set the DC Float voltage, the temperature compensation function must be disabled, or the Float
voltage setting may not be accurate due to the compensation due to the battery temperature. Once the
DC voltage is set, re-enable the Temperature compensation.
If the temperature compensation probe is disconnected, a Temperature Compensation Failure alarm will
occur.
7.7.2. Battery Voltage & Current Monitoring
This option (# 210) provides battery current and voltage monitoring. Separate battery input terminals
are provided for direct connection to the batteries.
With this option, Battery Current Limit is provided. With this feature the charger current control
regulates the amount of current that flows to the battery. When the current charging the battery
exceeds the battery current limit setting, the Charger shall reduce the DC output voltage until the
battery current is at or below the battery current limit setting. If the DC voltage reaches 110V the
current limit will stop. Overall charger current limit still remains in force. To modify the Battery current
limit, go to User interface Setup -> Adjustments -> Battery Current Limit Menu enter new value. Default
current limit is 90% of rated output current and adjustment range is 25% to 100%.
Battery Discharging Alarm
In addition, a battery discharging alarm is provided. If the battery current to the load exceeds 5% of the
rated current an alarm will occur. The discharge current may be adjusted from 1A to 20% of rated
output current. An alarm relay may be configured for remote annunciation, normal operation the alarm
relay is energized.
Battery History Screen
Each battery discharge is recorded in the Battery History screen. Which includes the number of battery
discharges, time on the battery, and historical and recent battery voltages. Battery History is viewed in
Diagnostics -> Battery History, screen to view the data log go to Battery Log.
The battery statistics may be reset using the Setup -> Reset Data -> Battery History Screen.
Each battery discharging alarm is data logged in the Battery History Log. These can be viewed using
