For stand-alone amplifiers, when a fault
condition occurs, the amplifier may be placed in
Standby mode (Standby LED will be lit), depending
on the amplifier configuration and the fault condi
-
tion. To release the amplifier from Standby mode,
clear the fault condition and then press the Reset
button. If the amplifier is in Run mode when the
fault condition occurs, pressing the Reset button
will return the amplifier to Run mode. If the amplifi
-
er is in Stop mode when the fault condition occurs,
pressing the Reset buttonwill return the amplifier to
Stop mode.
When the amplifier is part of a multi-amp system,
pressing the Reset button on the amplifier report
-
ing the fault condition will clear the condition and
return all amplifiers to Run or Stop mode; pressing
the Reset button on other amplifiers in the system
will NOT clear the fault condition.

3.2.1 Main Status Indicators
Four Main Status indicators are located on the
amplifier’s front-panel. These LEDs monitor the
internal conditions of the amplifier and indicate the

Run mode:
The amplifier’s high-voltage trans

formers 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

Standby mode:
Standby mode indicates that
the amplifier 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 ampli
-
fier will enter Standby mode briefly after power
-
ing up, and then will move automatically into Run
mode. In Standby mode, the amplifier’s low-voltage
transformer is energized but the high-voltage trans
-
formers are not.
If the amplifier remains in Standby mode, it is
being held in Standby by remote control through
the SIM Interlock I/O connector. Open the En
-
able/Standby switch to clear this remote Standby
condition and return the amplifier to Run mode.

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