3 SERVICE RE2100
These error codes are described more detailed in the instruction manual for T2130, chapter
2.3 SYSTEM DESCRIPTION AND TROUBLE SHOOTING, and in the chapter 3.4 TROUBLE SHOOT-
ING.
ERROR CODES
70 Motor circuit error AT2110.
See instruction manual for T2130, chapter 3.4.
71 Internal signal error.
See instruction manual for T2130, chapter 3.4.
72 Internal signal error.
See instruction manual for T2130, chapter 3.4.
73 High standing wave ratio (SWR) in the tuning of the AT2110.
Check the aerial and see instruction manual for T2130, chapter 3.4.
74 Transmitter temperature too high.
Let the transmitter T2130 have a pause and see instruction manual for T2130, chapter 3.4.
75 High standing wave ratio (SWR) when transmitting.
Check the aerial and see instruction manual for T2130, chapter 3.4.
76 Battery voltage low.
Check the condition of the batteries and the power cables. See instruction manual for T2130,
chapter 3.4.
77 Temperature sensor error.
See instruction manual for T2130, chapter 3.4.
78 Internal high standing wave ratio (SWR).
See instruction manual for T2130, chapter 3.4.
If the error codes indicate that the fault may be found in the RE2100, the fault is probably no transmitter
signal from the RE2100. The exciter can then, without any damage to the transmitter, be set on by
activating the test programme SP-05-0.
The error codes do not indicate any receiver fault.
A receiver fault can be in the aerial coupler AT2110, in the transmitter T2130, or in the receiver unit.
To separate a fault in these units, disconnect the aerial cable at the back of RE2100 and connect a wire
to the RE2100 coax socket. Try to find a broadcast station and check the receiver. If the fault is still
present, it must be located in the RE2100 unit.
LOCATING THE FAULTY MODULE
If the fault has been located to the RE2100, the exciter can be activated in test programme SP-05-0. The
receiver is always activated, when no test programme is activated.
Check the connections to the modules in the RE2100.
The power supply should be the first thing to control, the voltage is indicated in the diagram of each
module.
If the power supply is present, control the amplitude of the local oscillator signals.
The next thing to control is whether the other inputs to the module are present. They are indicated in the
diagrams of each module with reference to a special set-up of the RE2100.
It should now be possible to locate the faulty module.
LOCATING THE FAULTY CIRCUIT
When the faulty module has been found, it can be difficult to find the faulty circuit or component.
One way is to change the module. If this is not possible, the faulty component or circuit can be found in
a more systematic way by using the chapter 3.6 MODULE PERFORMANCE CHECK.
Chapter 3.6 MODULE PERFORMANCE CHECK is divided into sections with a headline indicating a
possibility of checking some main parameters, and this may be a great help.
