4 Using the Regenerative Power System
corresponding signal is true. Refer to
digital port pins.
Lastly, you must enable output sequencing to use OnCouple and OffCouple signals to enable or
disable the output. Refer to Enable Output Sequencing below.
Sequencing Multiple Units
To sequence the output turn-on for multiple units:
1. Connect and configure the digital connector pins of all units.
2. Enable the sequence function on each unit.
3. Specify the user-programmed turn-on delay for each unit.
4. This step is required if you have power supplies with different minimum delay offsets (see below).
Specify a common delay offset for all of the sequenced units. The common delay offset must be larger
or equal to the largest maximum delay offset. When the common delay offset completes, the user-
programmed turn-on delays will start.
Connect and Configure the Digital Connector Pins
The digital connector pins of the sequenced units must be connected together and configured. Refer
to Output Couple Control
Enable Output Sequencing
Output turn-on sequencing must be enabled on each unit that will participate in output turn-on
synchronization.
Front Panel Menu Reference
Select Output\Sequence\Couple.
Check Enable to enable sequencing.
Uncheck to disable.
Specify the Turn-On and Turn-Off Delays for each Unit
Turn-on delays can be specified for all coupled units. Any delay sequence can be implemented. There
are no restrictions on what the sequence is or what unit comes up first.
Front Panel Menu Reference
Select Output\Sequence\Couple.
Specify the Turn-on delay in seconds.
Repeat for each additional unit.
Turn-off delays can also be specified for all coupled units. Any delay sequence can be
implemented. There are no restrictions on what the sequence is or what unit turns off first.
