Amplifier Indicates whether the amplifier has been switched on or off by the R&S
TCE900.
Off, On Read Only
Mute Indicates that the amplifier is suppressing its output signal.
This indicator appears in the following cases:
●
No input signal is present
●
During bias adjustment
●
An external absorber signals via connector X11 that it is overheat-
ing.
No, Yes (warn-
ing)
Read only
RF Power Fail Indicates that the output power of the amplifier is more than 3 dB below
the nominal value.
No, Yes (Fault) Read Only
Temp. Fail Indicates that the amplifier has overheated internally.
The shut‑off taps for the coolant must be checked. They must be open.
The occurrence of this message is stored in a nonvolatile memory.
After the reason for the overheating has been rectified, this message
must be reset manually by pressing the "Reset Faults Transmitter" but-
ton or "Reset Faults System" button.
No, Yes (fault) Read only
Supply Fail Indicates that one of the internal power supply units is probably not
working.
No, Yes (Fault) Read Only
Link Indicates whether a communication link exists between the amplifier
and the R&S TCE900 Tx control.
If no link exists between the amplifier and the R&S TCE900 Tx control,
check the power supply of the amplifier.
On, Off Read Only
Regulation Fail Indicates that the internal power regulation of the amplifier has reached
the limit of its control range.
This is an indication that one or more power transistors are defective.
This fault can also occur if the amplifier performs a system check fol-
lowing a TRANSISTOR_FAIL and then continues to run at reduced
power.
No, Yes (Fault) Read Only
RF In Fail Indicates that the amplifier is receiving an input signal, the level of
which is too low.
●
If this message occurs at all amplifiers at the same time, the fault
is located at the exciter switch, splitter or exciter.
●
If this fault occurs at only some of the amplifiers, the output level
of the exciters and splitter must be checked.
●
If the fault occurs at only one amplifier, the self‑engaging connec-
tor of the RF signal on the rear panel of the amplifier must be
checked for mechanical damage.
No, Yes (Warn-
ing)
Read Only
Amplifier Temp. Indicates the temperature of the amplifier. The amplifier should only be
switched on at temperatures above 0 °C.
0 °C to 150 °C
Read Only
AC Fail Indicates a fault if the mains voltage has been interrupted. The circuit
breakers must be checked in this case.
No, Yes (Warn-
ing)
Read Only
DC Fail Indicates whether one of the internal power supply units of the amplifier
is faulty (e.g. no DC voltage is being delivered).
Detection of a fault is only possible if the RF of the transmitter has
been switched on (Program on).
No, Yes (Fault) Read Only
