5 Advanced Configuration

The 7224/7226 amplifier was designed to offer
exceptional versatility in operation. You can choose
from a range of field-configurable options, including:
• Operate as a stand-alone amplifier or as part of
a multiple-amplifier system.
Operate with variable gain control or at a fixed
•
gain setting of 20.
Select Controlled-Current or Controlled-Voltage
•
modes of operation.
Trigger Standby mode when an overload condi-
•
tion occurs during operation.
Select the Stop mode state at power-up, or go
•
immediately to the Run mode state at power-up.
Configure for use in high voltage applications,
•
high current applications, or for applications
requiring mid-level amounts of both voltage
and current.
Your amplifier has been pre-configured to your
specifications before shipping from the factory.
These initial settings are detailed on your 7224 or
7226 Proof of Performance sheet and on a label
located on the side of the amplifier.
If you need to make changes to your amplifier's
configuration, please follow the instructions con-
tained in this chapter.
Do not attempt to access the Main Board
or Power Supply Board while the ampli-
fier is running. Turn the amplifier off and
disconnect the AC Mains before opening
the access panel.
After turning the amplifier off, let the unit
sit for 2 minutes before removing the ac-
cess panel. This will allow the electrical
charge in the Power Supply capacitors
to discharge.
