3 SERVICE RE2100
3.4 TROUBLE SHOOTING
Trouble shooting should only be performed by persons with sufficient technical knowledge, who have the
necessary measuring instruments at their disposal, and who have carefully studied the operation
principles and structure of the SAILOR Compact HF SSB System.
SAILOR HF SSB RE2100 has a number of trimming cores and trimmers, which must not be touched,
unless adjustments as specified in chapter 3.7 ADJUSTMENT PROCEDURE, can be made.
When measuring the units, short-circuits must be avoided as the transistors would then be spoiled.
LOCATING THE FAULTY UNIT
When a fault has been observed in the HF SSB system, it can be difficult to find out in which unit the fault
can be located.
The first thing to check, is whether the fault is somewhere in the aerial circuit, the handset or in the power
source.
If the fault is not found there, check if an error message has been shown in the RX display of the RE2100.
The error codes listed below are error messages, which are generated by the RE2100, and they therefore
indicate a fault in this unit.
ERROR CODES
00 Internal power supply is low.
Check the power connections to the RE2100, or check the internal power regulators.
11 Illegal transmitting frequency.
The TX frequency, of which a tone sequence has been tried, is not legal.
12 Illegal transmitting mode.
The TX emission mode is not legal for transmitting.
15 Key sequence is not finished by the <ENT> key.
20 The communication link to the transmitter T2130 is interrupted.
Check the coax cable to the T2130 from RE2100.
21 The communication link between RE2100 and control unit C2140 or DSC/telex RM2150/
RM2151 has been stopped. Check the SP-BUS coax cable to the external equipment. If the
“Error 21” flashes up again after the button <STOP/ENT> has been pressed, then check the
SP-BUS interrupt line (J03-5 pin 6). This line has to be normal “High” (approx. +5V).
22 The communication link between the RE2100 and the Duplex/Telegraphy Reveiver R2120T
has been stopped. Check the SP-BUS coax cable between these units.
The error codes listed below are error messages, which are generated by the HF transmitter T2130, and
they therefore indicate a possible fault in this unit.
