Self-help guide TR-EM-208 Check of power supply to the PCB 24 V Voltmeter EM-208 PCB 34 123 4 The supply must be 12/24 V DC. With the transformer TR-EM-XXX-T-230 the voltage will be 30-31 V DC. Check the 5 volt output 123 4 EM-208 PCB 5 V Check the internal 5 V supply to the microprocessor. The voltage must be 5 V. At lack of voltage, the PCB is detective. Voltmeter 4 10 Check the control signal (hand control) EM-208 PCB 123 4 Voltmeter 3 67 Negativ (NPN) Negative (NPN) Check the input signal terminal 6 and 7 respectively. It must be possible to measure a voltage between 5-32 V. Check that the jumper is placed correctly. 123 4 EM-208 PCB Voltmeter 4 67 Positiv (PNP) Positive (PNP) Check the input signal terminal 6 and 7 respectively. It must be possible to measure a voltage between 5-32 V. Check that jumper is placed correctly. LINAKTHIRDPARTY.COM
