3 SERVICE T2130 If the error has appeared because of an error in the measuring circuit, please refer to section 3.5.3.1. A/ D CONVERTER, +24 Volt Sense Measuring, in the instruction manual for T2130. 77. TEMPERATURE SENSOR ERROR The temperature is measured to be very high or very low, indicating an error in the temperature measuring circuit. Please refer to section 3.5.3.1. A/D CONVERTER, Temperature Measuring in the instruction manual for T2130. 78. INTERNAL SWR TOO HIGH The SWR in the internal dummy load used for the automatic power setting is higher than certain limits. For frequencies lower than 20 MHz the SWR is 1.2. For frequencies above 20 MHz the SWR limit is 1.6. Please refer to the circuit description for the Output Filter (2) section 3.4.2. in the instruction manual for T2130. PAGE 3-4
3 SERVICE T2130 3.4.1 POWER AMPLIFIER (MODULE 1) Connect a 50 ohm load to RF in/out (ST04) on the Connection Board (6). 3.4.1.1 ERROR 71. VFORWARD LOW This means that there is no output from the PA-module. Select service programme SP-29, see section 3.9.1. 3.4.1.2 Check the RF-input level on the PA-module (1). Approx. 1.2 Vpp. 3.4.1.3 Check the RF-output level on the PA-module (1). Approx. 200 Vpp. 3.4.1.4 Check of bias. Note only when the output is zero. See chapter 3.6. ADJUSTMENT PROCEDURE, sections 3.6.1.1 to 3.6.1.4. 3.4.1.5 If the measurement above is ok, then the fault is probably to be found in the Output Filter (2). 3.4.1.6 ERROR 74. TRANSMITTER TEMPERATURE HIGH The temperature on the output transistors is too high. 3.4.1.7 Check that there are free air circulation around the transmitter and the ambient temperature is not more than 40°C. If the temperature is higher the performance will be reduced. 3.4.1.8 Check R45 (temperature sensor) located on one of the screws holding Q10 (see component location for Power Amplifier (1) in chapter 5.1). When it is 25°C the resistance is 2.00 Kohm. 3.4.1.9 Check if the output transistors have a good thermal contact to the heatsink. IMPORTANT! Always use thermal compound for the power transistors. (e.g. Wakefield part No. 120-8 or equivalent). PAGE 3-5
