Battery Test
Battery Test is a preventative maintenance tool that monitors the discharge capabilities to
ensure that the condition of the battery has not deteriorated over time.
The SC200 temporarily reduces the output voltage of the rectifiers to just below the bus voltage
for a set duration. The battery then supplies power to the load. A battery test passes if the
battery voltage remains above a predetermined level for the duration of the test.
Battery Tests can be scheduled to occur at regular intervals, and/or can be started/stopped
manually, and/or can be started by an external relay contact or switch.
 Battery Test does NOT function during a Fast Charge or Equalize, or during the lock-out period
after an ac supply failure.
 If a Digital Input has the function "Start Battery Test" then a Battery Test will start when the
Digital Input becomes active.
► To enable Battery Test (or to start or stop a test manually)
Use the SC200 keypad to go to: Control Processes > Battery Test.
Or, in DCTools/Web go to: Control Processes > Battery Test
► To use an external relay contact to activate a Battery Test (optional)
Connect a voltage free relay contact or switch to any Digital Input.
In DCTools/Web go to Digital Inputs.
Configure the selected Digital Input and set Function to Start Battery Test.

Next Start Time
The start time of the next scheduled Battery Test.
 Time shown on SC200 is UTC. Time on PC
running DCTools/Web is local time. See SC200
Internal Clock on page 14.
Remaining Time
The time to the end of the currently active Battery Test.
Battery Test
Lockout Remaining
The time remaining until a Battery Test can be started.
Battery Tests cannot be started within 48 hours of an ac
supply failure.
Voltage Offset
The adjustment to the bus voltage being applied due to
the Battery Test. While a Battery Test is running, the
rectifiers are turned down to force the battery to carry
the load.
