Regenerative DC Bus Supply Operation
Control and Signal Wiring

Important: Fuse R47 is self-resetting and will open should a low
impedance or short circuit occur at J15 during
24VDC operation. Should a fault occur, allow (1)
minute after removal of power from the Converter
Control Board for R47 to cool before reapplying
power.
Important: For Regenerative DC Bus Supply applications, the
1336 REGEN Line Regeneration Package will be
used with one or more common bus drives. 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.
External Fault
Allows a customer supplied external signal to be wired into the
1336 REGEN Converter. Opening this contact issues an external
fault command, disabling the converter.
External Reset
Resets the 1336 REGEN Converter when closed. If the converter
has faulted, closing this contact clears the fault and resets the
converter.
Enable
For the 1336 REGEN Converter to modulate, an enable signal
must be present at J15 on the 1336 REGEN Converter Control
Board. Opening this contact disables the converter. When this
contact is closed, the Enable LED on the Control Board will be lit.
Digital Output Signals
(2) form C, N.O./N.C. output relays are available at J16 on the
1336 REGEN Control Board to provide external warning or fault
change-of-state signals.
Resistive Rating = 120VAC/30VDC, 5.0A
Inductive Rating = 120VAC/30VDC, 2.0A
Contacts are Shown in the Unpowered State
J16
Fault Output - The fault output is used to indicate that
6
the 1336 REGEN Converter is faulted with either an
internal or external fault.
FAULT RELAY
5
Note: The unpowered state of the fault relay is the
opposite of the faulted state—or the unpowered state
4
of the fault relay indicates an unfaulted condition.
3
Enable Output - The enable output indicates that the
1336 REGEN Converter is modulating. An enable
ENABLE RELAY
2
signal must be present on J15 and the 1336 REGEN
Converter must not be faulted for the enable output to
1
be active.
