18 Operation www.ets-lindgren.com
Fault Indicator (Red LED)
Should a fault be detected, the red LED on the centre unit front panel will be
illuminated. The amplifier will be forced into standby mode and the unit will cease to
function (only the fans will continue to operate). This action is latching, therefore only
when the fault has been cleared can the amplifier be reset; this is done by pressing
the standby/operate switch.
The reasons for the system fault light to illuminate are as follows:

Excess module temperature

Air cooling failure (fans failing to operate)

Power supply failure
Interlock Indicator (Orange LED)
When the rear panel interlock is activated the interlock indicator will illuminate and
the amplifier gain stages will all be turned off. This action is latching; therefore, the
amplifier will return to Standby mode when the interlock is released.
Local Lockout Indicator
This indicator is used when the USB/GPIB Interface option is fitted. Refer to the
separate Remote Control Interface manual supplied.
RF Input (Depending on model)
The RF input will accept a signal from an RF generator. This input must be within the
operating frequency range of the 8000-003 amplifier system. An amplitude of up to
0dBm will be sufficient to saturate the amplifier. Operation outside the specified
frequency range should not be attempted as it may subject the amplifier to undue
internal stress.
RF Output (Depending on model)
WARNING: The centre conductor of the RF output represents a severe
burn hazard to personnel.
Never operate the amplifier without a proper termination or with defective
cables or connectors.
This connector must be suitably terminated at all times during operation. Ensure that
the cable is capable of handling the power available, which may be as much as
900 watts.
