Initial Operation
Important: For Regenerative DC Bus Supply applications, the
1336 REGEN Line Regeneration Package will be
used with one or more common bus drives (see
Figure 2.1). It is recommend that the fault relay on
the 1336 REGEN Converter Control board be
interconnected into the common bus drive(s) control
logic. This will allow coordination the Regenerative
DC Bus Supply faults with the common bus drive.
1. Verify that AC line power at the disconnect device is within the
rated value of the 1336 REGEN Package.
2. Verify that the digital inputs are configured as described in the
Control and Signal Wiring section. Ensure that jumpers J10, J11
J18 on the 1336 REGEN Converter Control Board are set cor-
&
rectly.
3. Set the converter logic to Not Enabled by presenting a logic
"low" at terminal 4 of J15.
4. Confirm that all other control inputs and outputs are connected
to the correct terminals and are secure and de-energized. In
addition, confirm that the external fault circuit is closed.
5. Replace all 1336 REGEN Package covers.
6. Apply AC power and control voltages to the Regenerative DC
Bus Supply System. The 1336 REGEN Converter HIM display
should light and display a status of
If the system detects a fault, a brief statement will be shown on the
display. Record this information, remove all power and correct the
source of the fault before proceeding. Refer to Chapter 4 for fault
descriptions and troubleshooting.
The remaining steps in this procedure are based on factory default
settings. If the 1336 REGEN Package has been previously
operated, parameter settings may have been changed and may not
be compatible with this startup procedure or application.
Important: To obtain proper results, the 1336 REGEN Package
must be set to Not Enabled and it's parameters reset
to factory defaults.
Setting parameters to factory defaults with the 1336 REGEN
Line Regeneration Package set to Enabled will result in an
EEProm error. Setting the converter logic to Not Enabled by
presenting a logic "low" at terminal 4 of J15 will clear the error
and restore the
