Lucent Technologies 415B Battery Plant for 4ESS
Issue 6 September 1999
Retrofit of 415A Battery Plant 7 - 19
Testing for
Group 3 (One
or Two
Rectifiers)
Required Test
Equipment
Depending upon the tests to be performed, one or more of the
following may be required.
•
DMM (Digital Multimeter) Fluke
®
8060A or equivalent
meter having ±0.02 percent accuracy on the dc scale
•
Battery Plant Simulator Test Set, customer constructed, or
equivalent (see Note below)
•
DC Dummy Load Bank, 150-volt, with adjustment to
provide a load of at least 10 to 12 percent of the rectifier's
rating (see specific test procedure to determine ampere
setting required)
•
Jeweler’s screwdriver for adjusting potentiometer
Simulated
Plant-Rectifier
Interface Tests
Using Test Set
(ITE 7102)
The following tests will verify that the rectifier responds
properly to plant controller commands and outputs proper
signals in return. It may be helpful to refer to the Schematic
Drawing (SD-83325-01) during performance of the procedures.
Note
The Battery Plant Simulator Test Set, listed above, is a
convenient tool used to isolate communication troubles
between the plant controller and the rectifier. It simulates the
plant controller relative to receiving signals from, and sending
signals to, the rectifier. If the rectifier works properly with the
test set, the problem is either at the controller or in the
interface wiring (plant cable). This tool can be ordered from
ITE (ITE-7102).
DANGER
Voltages in excess of 600 volts are present in the rectifier.
Extreme care should be exercised to avoid contact with
exposed terminals or bus bars.
