DIP Switch
Settings
This section describes the DIP switch settings on circuit modules in
theJ85503C-3 rectifier. Figures 5-7 and 5-8 show the DIP switch labels
inside the rectifier door. Figures 6-2, 6-3, 7-1, and 5-6 show CM1,
CM2, CM3, and CM4, respectively. If the settings on the rectifier do
not meet the requirements of your plant, change them according to this
section and label.

Board (CM2)
S1.1 through S1.5 and S1.8 ensure stable rectifier output voltage for
various Lucent Technologies rectifiers. For the J85503C-3, the switches
are factory set for operation with a battery. If the rectifier is operated
without a battery, change S1.1, S1.3, S1.7 and S1.8 to the settings
indicated in the options column of Figure 5-7.
If the J85503C-3 rectifiers are being operated in a bus bar plant
configuration (List 7), set S1.1, S1.2, S1.3, S1.5, S1.7, S1.8, and S1.10
to the On position as indicated in the options column of Figure 5-7.
S1.6 controls the time of the walk-in circuit and is factory set for a
walk-in time of about 10 seconds. Changing the factory setting will
eliminate the rectifier walk-in.
S1.9 enables load share. The factory setting is off, (load share disabled).
S2.1 through S2.8 configure the rectifier as either a 24-volt or a 48-volt
rectifier. For the J85503C-3, S2.1 through S2.8 are factory set and
should not be changed.
S2.9 and S2.10 provide local or remote sense. In the factory setting
position, the rectifier senses the output voltages remotely via the
regulation leads. If the settings are changed, the voltage is regulated at
the output terminals of the rectifier.
S3.1 through S3.4 adjust the level of the backup high voltage shutdown
(BUHVSD). See Table A of Figure 5-8 for the range of BUHVSD
settings. The factory setting is 59.5 Vdc.
S3.5 and S3.6 are factory settings that notify the control circuit that the
rectifier is configured as a 48-volt rectifier.
S3.7 and S3.8 permit the internal selective high-voltage shutdown
(ISHVSD) level to be adjusted to 55, 56, 57, or 58 volts. The factory
setting is 58 volts.
S3.9 and S3.10 are not used.
