Page 48: Mechanical Adjustments
MECHANICAL ADJUSTMENTS Mechanical or electrical adjustments are described with a series of instructions complete with one or more figures. If necessary, operating procedures are provided, to be used as guides and to verify whether the purpose of the adjustment operation has been reached. NOTE: In the figure, a star indicates where you need to operate with a suitable tool (screwdriver, wrenches, etc.)
Page 49: Shutter Adjustment
SHUTTER ADJUSTMENT Checking the shutter opening mechanism In the resting position, plate 4 should have about 0.1 mm of play. To adjust, slightly bend flap 5 of plate 4. Shutter opening electromagnet adjustment Electromagnet 1 controls the inlet opening; its adjustment must assure that the shutter opens completely when the electromagnet is energized.
Page 50: Shutter Position Microswitch Adjustment
Shutter position microswitch adjustment Microswitch 3 controls shutter position; to adjust, proceed as follows. · Loosen the two screws that fasten the microswitch to the side of the shutter (indicated with a star in the figure). · Manually activate electromagnet 1 controlling shutter opening. ·...
Page 51: Card Presence Microswitch Adjustment
Card presence microswitch adjustment When card 1 is inserted in the inlet, it displaces roller 2 which, thrust outward by the card, activates microswitch 3. To adjust: · Loosen the two screws fastening microswitch 3 (highlighted with the star) · Insert at card into the inlet ·...
Page 52: Adjusting The Positive Drive Belt
ADJUSTING THE POSITIVE DRIVE BELT NOTE: If a belt is over tightened, its wear will be excessive and the motor may seize, whereas if it is under tightened it may flit. Both conditions would cause problems to the motion of the mechanisms driven by the belt.
Page 53: Adjusting The Contrast Rollers
ADJUSTING THE CONTRAST ROLLERS The three rubber rollers 1, 2, 3 for transporting the card have fixed positions whereas the three bearings A, B, C, have a variable position. The purpose of the adjustment is to obtain the distances specified below between the three pairs of rollers/bearings. ·...
Page 54: Checking Contrast Roller Adjustment
Checking Contrast Roller Adjustment · Insert a card between roller 1 and bearing A; verify that there is friction on the card upon its passage (Figure 1). · Repeat the operation for roller 3 and bearing C. · Insert the card between roller 2 and bearing B; in this case friction should be greater than in the previous cases (Figure 2).
Page 55: Read/Write Head Adjustment
READ/WRITE HEAD ADJUSTMENT To adjust: · Attach a dynamometer to read/write head 1 · pull in the direction indicated by the arrow · the load on the leaf spring should be about 390 grams (typical range 380÷400) · if not, act on screw 2 NOTE: An excessive pression on the card may cause a jam along the card path, while a tension too loose cannot guarantee the best contact between the read/write head and the card.
Page 56: Chip Card Electromagnet Adjustment
CHIP CARD ELECTROMAGNET ADJUSTMENT Electromagnet 1 moves the levers on which the contact board for reading the chip card is fastened. The purpose of the adjustment is to have proper coupling between the contact board and the chip card. · Insert a card under the contact board ·...
