| Procedures and Adjustments |
|
| Adjustments and corrective maintenance procedures required of the customer |
| are presented in the following subsections. |
| Belt Replacement and Adjustment |
|
| When periodic maintenance indicates that the belts need to be replaced, perform |
| Email:smt@smtsky.com,Website:www.smtsky.com |
| the following procedure for all belt replacement. Refer to the beam assembly |
| illustrations for belt routing. |
|
| 1. Power the insertion machine down. |
| 2. Loosen the screws that secure the right angle drive motor into the motor |
| block. |
|
|
|
|
| 3. Raise the right angle drive motor to release the tension on the belt and |
| slide the belt off the drive sprocket. |
| 4. Slide the belt off the convex pulleys, drive pulley and idler pulleys. |
| 5. Install the new belt onto the convex pulleys, drive pulley and idler pulleys |
| as shown. |
|
|
|
| Email:smt@smtsky.com,Website:www.smtsky.com |
| 6. Raise the right angle drive motor and slide the belt onto the drive |
| sprocket. |
|
|
|
| 7. Allow the weight of the right angle drive motor apply tension on the |
| belt. Mark the position of the right angle drive motor relative to the |
| motor block. |
|
|
|
| 8. Lower the right angle drive motor .125 inch from the mark made in |
| step 7 to increase the belt tension and secure it in position by tightening |
| the screw against the motor block. |
|
| Do not over tighten the drive belts. Excessive tension will put too much |
| pressure on the pulleys and drive mechanism causing premature failure. |
| Email:smt@smtsky.com,Website:www.smtsky.com |
| When properly adjusted, the drive belts will transfer a five pound board |
| without slipping. |
|
|
| End of procedure. |

| Sensor Adjustments |
|
|
| The board handling system uses sensors to signal various functional activities. |
| These signals are utilized by the software to control the timing of events |
| that occur during the board handling cycle. If a sensor signal is not received |
| or fails to deactivate as determined by the system, the system will go into a |
| transfer error condition and remain stopped until the error condition is corrected. |
| The sensors will not normally require adjustment. If sensor failure should |
| occur, use the following to determine proper sensor operation. The sensors |
| on the bridge assemblies are the most critical and a detailed sensor set up for |
| Email:smt@smtsky.com,Website:www.smtsky.com |
| these sensors is provided. |
|
| Bridge Slide (1003RS, 1004RS, 1103RS, 1104RS) |
| The sensors on the bridge slide mechanism sense the end of the stroke when |
| the bridges are fully elevated or lowered. When the piston is sensed in either |
| position, the red LED is illuminated. The green LED is a power indicator |
| and should be illuminated regardless of piston position. These sensors ensure |
| that the bridge mechanisms are either fully elevated or lowered before board |
| transfer can occur. |
|
|
| Bad Board Lift (1108RS) |
|
|
| The sensor on the bad board lift slide mechanism senses when the bad board |
| Email:smt@smtsky.com,Website:www.smtsky.com |
| lift is fully lowered. When the piston is sensed, the green LED is illuminated. |
| These sensor ensures that the bad board lift mechanism is fully lowered |
| before board transfer can occur. |
|
| Output Pusher (1107HS) |
|
|
| The sensor on the output pusher senses the full retraction of the pusher piston. |
| When the piston is sensed, the red LED is illuminated. This sensor ensures |
| that the pusher is fully retracted before board transfer can occur. |
| Transfer Mechanism (1011RS, 1111RS, 1112RS) |
| The sensors on the transfer mechanism senses the fully extended and retracted |
| positions as well as the slow down position. When the piston passes |
| Email:smt@smtsky.com,Website:www.smtsky.com |
| the sensors a yellow LED on the sensors is illuminated. The sensors on either |
| end of the transfer assembly ensure that proper board transfer has occurred. |
| The slow down sensor ensures that the board transfer mechanism |
| smoothly transfers the boards to the output bridge, by slowing the transfer |
| mechanism near the end of its stroke. |

|
| T46365906 Rev. D Dual Head Board Handling System L/R |
| Auto Miss Marker (17PRS, 18PRS) |
|
| The sensor on the auto miss marker senses the full retraction of the air cylinder |
| Email:smt@smtsky.com,Website:www.smtsky.com |
| piston. When the piston is sensed, the red LED is illuminated. This sensor |
| ensures that the air cylinder is fully retracted before the positioning system |
| movement can occur. |
|
|
| Bad Board Hopper (1109LS) |
|
|
| The sensor on the bad board hopper is a micro switch that detects when the |
| bad board hopper is full of boards. This sensor should be adjusted to actuate |
| when the level of boards in the hopper is near the top of the hopper. |
| Bridge Sensor Adjustments (1000PS, 1001PS, 1101PS, |
| 1102PS) |
|
|
|
|
| The sensors on the bridge assemblies sense the board locations during board |
| Email:smt@smtsky.com,Website:www.smtsky.com |
| transfer. The sensor red LED is illuminated when no board is present under |
| the sensor and extinguished when a board is sensed. The green LED illuminates |
| when a board is present under the sensor, indicating a stable signal. |
| The green LED does not illuminate when there is no board present (red LED |
| illuminated). |
|
|
|
| There are two types of adjustment that may be required when different |
| boards are used on the board handling system. The first type of adjustment is |
| for the sensor sensitivity. This may be required if board color or opaqueness |
| changes. The second type of adjustment is for the position of the sensor. |
| This may be required if the board has cut outs or notches. |
| Email:smt@smtsky.com,Website:www.smtsky.com |
| These sensors ensure the boards are in a safe position for board handling |
| functions. |
|
|
|
| Sensitivity Adjustment |
|
|
| Remove the board from under the sensor and turn the adjustment potentiometer |
| clockwise to find point A where the red LED extinguishes. If the red |
| LED does not turn off, turn the potentiometer to the maximum clockwise position |
| and take this as position A. |
|
| With the board in position under the sensor turn the potentiometer counterclockwise |
| and find point B where the green LED extinguishes. |
| Set the potentiometer at a point midway between points A and B. Confirm |
| Email:smt@smtsky.com,Website:www.smtsky.com |
| sensor operation where the red LED illuminates with no board present and |
| the red LED extinguishes and the green LED illuminates with a board |
| present. |

| Position Adjustment |
|
|
| Correct positioning of the sensors is very critical. Improperly |
| Email:smt@smtsky.com,Website:www.smtsky.com |
| positioned sensors may cause damage to the board and the Board |
| Handling System. Refer to the operation manual for details relating to |
| specific sensor designations for right to left or left to right transfer |
| directions. |
|
|
|
| The PCB in Gap Outside Left sensor (1001 PS) on the input bridge senses |
| that a board has completely entered the input bridge. If the board fails to |
| fully enter the bridge and the sensor remains activated, the system prevents |
| the bridges from being raised or lowered. The sensor must be set so the |
| green LED is illuminated when any part of the board is not completely on the |
| input bridge. |
|
|
|
| Email:smt@smtsky.com,Website:www.smtsky.com |
| The PCB at Outer Left Belt sensor (1000 PS) on the input bridge senses the |
| first board to enter the input bridge, starting a time delay to drive this board |
| against the inner board stop. The sensor then senses the second board to enter |
| the input bridge and stops the input bridge drive belts. The sensor must |
| be set to sense the second board when it is against the outer board stop. This |
| sensor continually monitors board position and, if a board is not seen, activates |
| the drive mechanism to keep the boards positioned against the input |
| bridge stops. |
|
|
|
| The PCB at Inner Right Belt sensor (1102 PS) on the output bridge senses |
| that the boards have properly entered the bridge when it senses both boards. |
| Email:smt@smtsky.com,Website:www.smtsky.com |
| If the boards fail to fully enter the bridge and the sensor is not activated |
| twice, the system prevents the bridges from being raised or lowered. The |
| sensor must be set so the red LED extinguishes when the board from |
| workboard holder 2 is fully on the output bridge. |
| The PCB in Gap Outside Right sensor (1101 PS) on the output bridge senses |
| that a board has been completely removed from the output bridge before allowing |
| the bridges to be lowered. The sensor must be set so the green LED |
| is illuminated when any part of the board is not completely on the output |
| bridge. The sensor also senses the leading edge of each board during transfer |
| and sets a time delay before the output board pusher is activated. |

|
|
|
|
| The board located at head 1 sensor (1005 PS) on the actuator assembly |
| senses when the tooling pins are properly engaged in the board locating |
| holes. If the tooling pins fail to properly engage the locating holes and the |
| Email:smt@smtsky.com,Website:www.smtsky.com |
| sensor remains activated, the system prevents the bridges from being raised |
| or the insertion process to start and causes a TRANSFER ERROR. Improper |
| location of the tooling pins is when the pins are hitting the board or no board |
| is present and the pins rotate beyond the correct position. The sensor must be |
| set so the red LED is illuminated when the tooling pins are engaged in the locating |
| holes in the board. |
|
|

| or the insertion process to start and causes a TRANSFER ERROR. Improper |
| location of the tooling pins is when the pins are hitting the board or no board |
| is present and the pins rotate beyond the correct position. The sensor must be |
| set so the red LED is illuminated when the tooling pins are engaged in the locating |
| holes in the board. |
|
|
| The tooling pin sensors require adjustment when the board thickness changes |
| or the size of the locating holes changes. If either of the conditions accur, adjust |
