Self-help guide TR-EM-273 EM-273 PCB v.3 Control of power supply to the PCB 10-35 V Voltmeter 1 2 + _ EM-273 PCB v.3 Check that the jumper is placed correctly (see Quick guide). Power supply 12/24 V DC. With the transformer TR-EM- XXX-T-230 the voltage will be 30-31 V DC. EM-273 PCB v.3 5 V EM-273 PCB v.3 Check the 5 volt ou 3 tput 16 17 25 Voltmeter 5 V 10-35 V Voltmeter Voltmeter 3 1 2 + _ Check the internal 5 V supply to the microprocessor. 25 The voltage must be 5 V. At lack of voltage the PCB is defective. EM-273 PCB v.3 Check the supply to Hall / Hall-Potentiometer 5 V 3 Voltmeter Check the supply to Hall at terminal 16 or 17. Placing of jumper: 16 17 25 = Supply voltage = Supply voltage minus 6 V = 5.5 V LINAKTHIRDPARTY.COM
