26 Truecharge2 Series Battery Charger Owner’s Guide
Installing a Parallel Configuration
Powering up after installing a parallel configuration:
1. Follow the procedures in “Step 5: Powering Up” on page 24.
2. Observe that the Parallel LED on the remote panel lights up to indicate
that two chargers are in parallel configuration charging mode.
During Charging
The two Truecharge2 Battery Chargers’ output currents are synchronized
during most of the charging cycle. When a battery is approaching a fully
charged state, it is normal to see one charger’s output current drop down
earlier than the other charger. The output current displayed via the remote
panel lights is the sum of both chargers’ output currents divided by the total
maximum current ratings of both chargers.
When Configuring the Battery Chargers
The secondary charger’s configurations are automatically synchronized
with the primary charger. The configuration can be performed from either
the remote panel or the primary charger’s onboard display. Follow the
exact same procedures as a single charger when configuring the paralleled
chargers.
When Equalizing Batteries
Equalization can be programmed and cancelled through the remote panel.
Equalization can be cancelled through both charger’s onboard display.
Fault and Warning Conditions
• When one charger encounters a fault condition, the other charger
remains charging but the remote panel will stop synchronizing the two
chargers’ settings at this point. The remote panel will display the fault
condition via Fault/Warning LED the same way as the “faulty” charger
displays it on its onboard display.
• Remote panel’s Fault/Warning LED only clears when fault or warning
conditions at both chargers are cleared. The remote panel will resume
synchronizing the two chargers’ settings at this point.
Exiting parallel operation:
Once the remote panel enters parallel operation, the only way to exit out of
it is to completely power down the remote panel by unplugging both of the
communication cables.
