Self-help guide TR-EM-288 EM-288 PCB EM-288 PCB Check of power supply to the PCB 24 V 24 V Voltmeter Voltmeter 1 4 1 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. EM-288 PCB Check the 5 volt out E p M u -2 t 88 PCB 5 V 5 V 1 Voltmeter 1 Voltmeter Check the internal 5 V supply to the microprocessor. The voltage must be 5 V. At lack of voltage, the PCB is defective. 14 14 Che E c M k -2 t 8 h 8 e PC c B ontrol signal (hand control) EM-288 PCB EM-288 PCB EM-288 PCB Check the control signal - positive (PNP). Check that there is a signal between 5 – 32 V. Voltmeter Voltmeter 8 12 8 12 Voltmeter Voltmeter 5 8 5 8 Check the control signal - negative (NPN). Check that there is a signal between 5 - 32 V. NOTE! Parameter 3 must be set at the requested control signal: 0 = Input PNP 1 = Input NPN LINAKTHIRDPARTY.COM
