Enable button is pressed on each amplifier, that
amplifier will be placed in Ready mode (Ready and
Standby LEDs lit) and remain in Ready mode until
all amplifiers in the system have been Enabled.
The system will automatically proceed to Run
mode when all amplifiers in the system achieve
Ready mode.
Stop –
For stand-alone amplifiers, Stop will place
the amplifier in Standby mode (both Standby and
Stop LEDs will be lit). When the amplifier is part of
a multi-amp system, pressing the Stop button on
any amplifier in the system will place all amplifiers
in Standby mode. When an amplifier is in Standby
mode, the low-voltage transformer is energized but
the high-voltage transformers are not.
Reset –
For stand-alone amplifiers, when the am
-
plifier has stopped due to a fault condition, press
-
ing the Reset button will return the amplifier to Run
mode if the condition causing the fault condition
has been cleared. When the amplifier is part of a
multi-amp system, pressing the Reset button on
the amplifier reporting the fault condition will return

Run mode:
The amplifier’s high-voltage transformers
are energized and the unit will amplify the input signal.
Run mode is initiated by: (1) the Enable push button, or
(2) when the amplifier powers up in Run mode (factory
default). See the “
Advanced Configuration”
section for
more information.

Standby mode:
Standby mode indicates that the am-
plifier is functioning properly and all Fault Status modes
are clear, but it is being held in Standby by an external
condition. As configured from the factory (Run mode on
startup), the amplifier will enter Standby mode briefly
after powering up, and then will move automatically into
Run mode. In Standby mode, the amplifier’s low-voltage
transformer is energized but the high-voltage transformers
are not.
If the amplifier remains in Standby mode,
it is being held in Standby by remote con
-
trol through the SIM Interlock I/O connec
-
tor. Open the Enable/Standby switch to
clear this remote Standby condition and
return the amplifier to Run mode. See the
“Applications”
section of this manual
for more information on remote amplifier
operation.

In Stop mode, the amplifier’s low-voltage transformer is
energized but the high-voltage transformers are not.
To release the amplifier from Stop mode,

information on how to clear fault conditions and
restore amplifier operation.
4.1.4 Main Status Indicators
Four Main Status indicators are located on the
amplifier’s front-panel (see
Figure 4.4
). These
LEDs monitor the internal conditions of the ampli
-
fier and indicate the current state of operation. The
chart in
Figure 4.5
details the operational modes
indicated by the Main Status indicators.
