Configuration
Set the following parameters.
Parameter
Description
Where to find:
First Start Time
The date and time that the first battery test cycle will
occur. Subsequent tests will occur at every Battery Test
Interval after that.
SC200: Control Processes >
Battery Test
DCTools/Web: Control
Processes > Battery Test
Interval
The time between scheduled battery tests. The interval
period begins at the start of a battery test. Zero disables
scheduled battery tests. Zero also disables the 48 hour
lockout following an ac supply failure, allowing an
immediate manual test.
Test Duration
The maximum time a Battery Test process will be
active. The battery test will pass if the bus voltage
remains above the Battery Test Termination Voltage
for the duration of the test.
Termination
Voltage
If the bus voltages drops below this value during a
Battery Test, then the test fails.
Equalize
Equalize charges batteries at a higher voltage after they have been fully charged to ensure that
all individual cell voltages are the same, that electrolyte is distributed evenly, and that sulfate
crystal buildup on the plates is reduced.
Equalize can be scheduled to occur at regular intervals and/or can be started/stopped
manually.
Refer to the battery manufacturer's instructions before using Equalize.
If a Digital Input has the function "Start Equalize" then a manual equalize cycle will start when
the Digital Input becomes active.
If Equalize cannot start at the scheduled time (for example when there is no ac supply) then its
state will be Pending and it will start as soon as conditions allow. Use Stop Equalize to cancel a
Pending Equalize.
► To enable Equalize (or to start or stop Equalize manually)
Use the SC200 keypad to go to:
Control Processes > Equalize
.
Or, in DCTools/Web go to:
Control Processes >
Equalize
.
► To use an external relay contact to activate an Equalize (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 Equalize
.
