1. Operating principle All the instrument models have the same basic design A voltage proportional to the plating current is produced across the measuring resis tance shunt this is amplified in the input amplifier A voltage frequency converter changes the amplified voltage into a proportional trequency A programmable frequency divider ensures that the Ah or Amin reading corresponds to the summation current The LED MB Monitor is operated when the measured voltage exceeds a pre set maximum or falls below a pre set minimum It indicates that reliable measurement is no longer ensured When the voltage falls below the minimum value a pulse blockage 5 activated which stops the count The counting pulses of the summation counter are also used to control the electronic dosing system Block circuit diagram Optokoppler Precision amplifier converter Pulse L block Ma range Elektronic dosing system 12V 5V 5V VV V Power supply ba_az2000_dsz FH5 0298 monitor gt Ik Imp 100Ah Amin 5 4 Instrument descriptions 0001 Be 2000 DSZ Be Amin ZAHLER ON a nk AZ 2000 DSZ This instrument operates as a summation counter witb a 6 digit electromechanical counter The reading is reset with a key This prevents unintentional changes in the counter reading With a difterent case size W x H 1442. ma be connected ZN Board SA SB SC SD Pre selecting switch S4 S5 S6 S1 S2 S3 IC 2 5 c o S 5 oO cl Sl S Circuit board for electronic dosing VPLS ALL LLL LLL LLP LA LED yellow O Circuit board for dosing preparation YASS SLPS PDS SSL EL SL l LED green ba_az2000_dsz FH5 0298 17
