Manual Test Type
Automatic Test
Type Selects between Disabled, 20%, Timed, and Amps-Hours Out test
methods. When Disabled, battery test will not be permitted. 20%
utilizes a patented algorithm that discharges the battery reserve by
about 20% from the detection of a coup de fouet and calculates a
reserve time. Selecting Time allows the discharge test to be run against
a user configured time threshold. Using Amp-Hours Out allows a
configured amp-hours amount to be removed from the nominal string
capacity. These tests can be run Manually or Automatically. Manual
tests can be implemented through the front panel or remote means. In
addition, the PBT/TR input can be used to assert a Plant Battery Test
(PBT). When PBT/TR is used for battery test, the controller will
monitor the assigned input and place the plant into the battery test
mode when the input is asserted.
Specific Edge controllers utilize the IN007 input for PBT. This input is
labeled as PBT/TR. To use the input, the Remote Group Standby (TR)
must be disabled and PBT enabled. This input can also serve as a
general purpose input by configuring the alarm assignment to
something else. Manual battery testing is factory Disabled.
Rectifier Voltage
During Test The rectifier voltage during test parameter defines the output voltage
the rectifiers will go to upon the initiation of a battery test. The range
for this setting goes from -42.00 to -52.00 Volts with a default of
42.00V and +21.00 to +26.00 Volts with a default of +21.00V.
Timed Test Alarm
Voltage Timed Test Alarm Voltage threshold is a user configured voltage
threshold that the timed discharge test utilizes to determine pass or fail
based upon the program Test Duration entered. If the system DC bus
does not reach this voltage during the programmed test duration, then
the test passes. Otherwise battery test failed is generated.
