PART II/H1252BPAGE 1-11 GENERAL INFORMATION1.1 INTRODUCTIONThis section gives you all the necessary informations to maintaine the DC power supply module. It alsospecify how to modify the printer to operate on DC supply instead of AC supply.1.2 PRINCIPLE OF OPERATIONThe power supply module is constructed to operate from a battery voltage of 10.5V DC to 32V DC todeliver the necessary voltages for the printer. The voltage conversion takes place in a “flyback” switchconverter, which is controlled by a current mode controller. The regulation of the output voltage iscontrolled via a separate winding of the transformer, which also deliveres the power for the control circuit.At the input and at the output are placed filters to suppress the switch noise.BLOCKDIAGRAMPWMINPUTFILTER CONVERTERSWITCH FILTEROUTPUTCONTROLCIRCUIT+-10.5V....32V +30V+10V284801.3 TECHNICAL DATAInput voltage range : 10.5V DC to 32V DCCurrent consumption : max. 4.5A (fuse = 6.3AT)Output voltages : 10V DC / 0.3A: 30V DC / 0.8ANoise from input terminals : better than CEPT Rec.

Then twist the wires to the switchto suppress noise.PART II/H1252B

MAINTENANCE/MODIFICATION PART II/H1252B2.3.2 MODIFICATION OF THE PRINTER MAIN CONTROL BOARDIf the printer is equipt with a DC power supply module of other type than from ECI, it is necessary tomodify the printer main board. As seen below, the diode D28 (D10) on the printer main board is shortcircuited.If the printer is equipt with a DC power supply module from ECI, module no. 628471 it is notrecommended to short circuit the diode D28 (D10) on the printer main board.Run the printer selftest programme.Switch on the ON-OFF switch and simultaneously press down the “line feed” button.After a few seconds (at low input voltage) the printer starts the selftest printing routine, which meansthat the DC power supply is OK.Switch off the printer.D28(D10)Main Control Board284792.3.3 REASSEMBLING OF THE PRINTERPlace the top cover by lifting the front end and place holes in the rear end into the two small hooks inthe bottom cabinet.To reassemble the printer, do the reverse procedure of the disassembling.Then run the selftest programme of the printer.

CONTENTS5 CIRCUIT DESCRIPTION 5-15.1 DC POWER SUPPLY 5-1PART II/H1252B
PAGE 5-15 CIRCUIT DESCRIPTION5.1 DC POWER SUPPLYTo suppress noise on the supply wires a filter is build around the current compensated choke L1.Furthermore the RC snubbers across the transformer prevent unwanted oscillations during transitiontime. The diode D7 in conjunction with R16 and C19 clamps the transient voltage spikes across theswitch transistor Q1.When the supply is switched on, the capacitor C6 is charged by means of R1 and when the voltageexceeds approx. 8.7V the controller U1 turns on. After a few cycles power is delivered from thebootstrap winding of the transformer to maintain the supply to the controller U1. When switching of thesupply voltage, the power from the transformer disappears. This means the supply voltage to U1decreases to approx. 7.6V and the controller U1 switches off.The rectified voltage from the bootstrap winding is also used to regulate the output voltages, whichmainly is determined by R8 and R11. The feedback voltage is led to U1 pin 2. The resistors R10 andR9 and the capacitor C17 form the compensating circuit for the voltage regulation.The controller is working at a fixed frequency of approx. 100 kHz, determined by R7 and C16.The switch current is sensed by R15 and led to U1 pin 3 after being filtered by R14 and C18. The currentsense voltage is a ramp voltage, which is compared to a DC level determined by the voltage regulationcircuit. When the ramp exceeds the DC level, the controller U1 switch off the FET Q1. This currentsense circuit forms a current regulation loop, which is stabilizing the over all regulation and preventshigh current to damage the switch transistor Q1.When Q1 is on, the output diodes D3 and D4 is reversed biased and current to the load is delivered fromthe capacitors C12 and C13. During the off time of Q1, the transformer outputs deliver the currents tothe capacitors C12 and C13 and to the load.The chokes L2 and L3 are parts of lowpass filters to suppress voltage spikes.Because of the converter principle , which is a ringing choke flyback type, without direct feedback fromthe output the voltages, the output voltages are load dependent.At input voltage under approx. 15V and at full load, the converter "changes frequency" and gets anirregular duty-cycle. That is normal behaviour.At low input voltage the start up time can be as long as 4 seconds, depending on the load.PART II/H1252B
