7800 SERIES OPERATION – SECTION 3
fier module reporting the fault condition will clear
the condition and return all amplifiers modules to
Run or Stop mode, depending on the status mode
the system was in when the fault condition oc-
curred. Pressing the Reset button on other ampli-
fier modules in the system will NOT clear the fault
condition.
Multi-Function LCD Display
Master Amplifier Module only.
The multi-function LCD display provides peak and
RMS values for voltage and current measured
directly from the amplifier output. If the amplifier
experiences a fault condition, the LCD display will
automatically display details of the fault condition
and prescribed corrective actions.
On startup, the LCD Display will provide readings
for all four measurements: Volts peak, Volts RMS,
Current peak, and Current RMS. Use the Naviga-
tion buttons to scoll to other available displays,
such as peak voltage and current only, RMS volt-
age and current only, or other combinations.

Main Status
Indicators State of Operation
Run mode: The amplifier's high-voltage transformers are energized
Run
and the unit will amplify the input signal. Run mode is initiated by: (1)
Ready
the Enable push button when the amplifier is in Standby mode, or (2)
Standby when the amplifier powers up..
Stop
Standby mode: Standby mode indicates that the amplifier is
Run
functioning properly and all Fault Status modes are clear, but it is be-
ing held in Standby by an external condition. The amplifier will enter
Ready
Standby mode briefly after powering up, and then will move automat-
Standby
ically into Run mode. In Standby mode, the amplifier's low-voltage
Stop
transformer is energized but the high-voltage transformers are not.
Stop mode: When the Stop button on the amplifier front panel
Run
is pressed, the amplifier will enter Stop mode. In Stop mode, the
Ready
amplifier's low-voltage transformer is energized but the high-voltage
Standby
transformers are not.

Information subject to change
Navigation Buttons
Master Amplifier Module only.
The Navigation buttons provide four arrow keys to
allow navigation through the different voltage and
current measurement functions on the LCD display
screen.
NOTE: The Enter button has been provided for
future expansion and has no function at this time.
Main Status Indicators
Four Main Status indicators are located on the am-
plifier module's front-panel. These LEDs monitor
the internal conditions of the module and indicate
the current state of operation. The chart in Figure
3.3 details the operational modes indicated by the
Main Status indicators.
In systems with multiple amplifier modules, the
Main Status indicators on each module are used
to determine the operational status of that module
and are also evaluated along with the statuses
of the other amplifier modules to determine the
system status and the action required to return the
system to a running condition. See Figure 3.4.

Action Needed to Return
to Run Mode
N/A
If the amplifier remains in
Standby mode, and it is not
part of a multi-amp system, the
amplifier module may require
servicing. Please contact AE
Techron Technical Support.
To release the amplifier from
Stop mode, press the Enable
button.
