Monitoring
The following information is available about the current state of battery charging.
Parameter Description Where to find:
Charge State Indicates current charging state (Charge / Float / Idle)
for the battery. Home Screen (above date
and time)
Battery Voltage Battery terminal voltage. Home Screen (Below
Battery Icon)
Battery Current Battery charging / discharging current. A discharge
current is indicated by a
– ve sign.
Home Screen (Adjacent to
Battery Icon)
Active Battery
Current Limit Battery current limit applied at present.
BATTERY CURRENT LIMIT
Battery Current Limit automatically limits the maximum battery recharge current to:
• Prevent excessive battery charge current in under-loaded systems
• Minimize gas release in VRLA batteries
• Control the load on a standby generator.
Two current limit values can be set (both are percentage of the C10 rating of the battery):
When the rectifier is switched ON, Rectifier voltage rises to below battery voltage and then increases to
achieve target voltage by maintaining set battery current limit. If alternate battery current limit is set and
engine is running, the controller will maintain alternate battery current limit while trying to achieve target
voltage.

Alternate Current Limit applies when the EC500 determines that an ac standby generator is
running. EC500 uses a Potential Free Input to determine If Engine is running. For Potential
Free mapping see section Digital Inputs.

Battery Current Limit (Normal) is always enabled
➢
To activate Alternate Battery Current Limit
•
If a Digital Input is required, connect a voltage free relay contact (that will
operate when the standby generator starts) to a Digital Input.
•
In Web go to Settings

PFC Settings


•
Configure the selected Digital Input and set ‘DG Sense’ PFC on required Digital
Input. Input Sense can also be set here.
•
In Web go to, Menu

Mode and set Alternate current limit .
MULTIPLE BATTERY BANKS
The C500 controller supports multiple battery banks. It can monitor battery current for an individual battery
and control charge voltage so that maximum charge current through any battery string is below the set Battery
Current Limit. This avoids over charging of parallel strings in case current sharing among battery strings is not
uniform.

All Battery strings should be of the same capacity.
