1.9. REPLACING THE DRAG HEAD To replace the drag head, proceed as follows:

1.

Take the knife holder out of the drag head. Make sure the knife does not protrude!

2.

Remove the front cover of the drag head by loosening the two screws .

3.

Loosen the flat cable by pulling the flat cable connector cover up. On both sides of the connector cover there is a small protuberance that you can pry up using a screwdriver. Gently pull the flat cable out of the connector .

4.

Remove the drag head. To do this, loosen the three screws with two counterclockwise rotations using a small diameter screw driver and lift the head upwards to remove it from the screws.

To re-install the drag head, proceed as follows: 1. Place the head back onto the screws. 2. Tighten the screws with a 1 1/2 clockwise rotation. Do not tighten them firmly because the height and position of the head still need to be adjusted. 3. Put the knife holder into the drag head 4. Secure the knife holder.

5. Adjust the height and position of the head. The standard operating procedure for doing this is described in the SummaSign Upgrade Kit (p/n 391-950). Even though the operating procedure described in the Upgrade kit applies to a tangential head, it is easy to be followed for a drag head. 6. Firmly tighten the screws once the drag head is properly positioned. 7. Put the flat cable back into the connector and close the connector. To ensure good contact, the flat cable must be positioned as deeply as possible and in the middle of the connector. 8. Remount the front cover of the head and firmly tighten the screws.

TROUBLESHOOTING 2-1

SummaCut Series Cutters

Service Manual

2.1 MOTOR HOT Cause: Heavy vinyl can overload the motors, especially the X-motor. The µP on the PCB calculates the power dissipated in the motors. When this dissipation becomes too high, the message MOTOR HOT appears. This is not a fatal error. After a while this message will disappear and the cutter will continue its operation. Action: 1. Wait until the motor has cooled down to an acceptable level. 2. Lower the speed using the Summa Cutter Control and use a lower knife pressure if possible. 3. Use lighter or narrower vinyl. 4. Check the camrollers and replace any damaged camrollers. 5. Call Summagraphics for assistance. A system register may have changed the default value. 6. Check whether the drive drum is turning smoothly (first switch the machine off and place the camrollers in the up-position). Replace motor and/or drum.

2.2. LOW LINE VOLTAGE Cause: The secondary voltage of the transformer is measured by the µP on the PCB. When it measures a value lower than the lower limit setting, the cutter will give this error. This is a fatal error. Switching the power off and making a corrective action is the only solution. Action: 1. Measure the line voltage. Check whether the voltage selector at the back of the cutter is set to the correct line voltage. The line voltage should be between the selected voltage +8% or -10%. 2. Check the secondary voltage of the transformer. It should be at least 22VAC. If not, replace the transformer. 3. Check the DC power on the PCB (on the power cable going to the cutter interface board). It should be at least 27VDC. 4. Disconnect the motor cables, the encoder cables, the flat cable going to the head, the fan cable, the sensor cables and the 28V power cable going to the cutter interface board, and switch the machine on again. When you have done this, plug in the cables one by one until the energy consumer is found. Replace it. 5. Replace the main PCB.

2.3. HIGH LINE VOLTAGE Cause: The secondary voltage of the transformer is measured by the µP on the PCB. When it measures a value higher than the upper limit setting, the cutter will give this error. This is a fatal error. Switching the power off and making a corrective action is the only solution. Action:

Measure the line voltage. Check whether the voltage selector at the back of the cutter is set to the correct line voltage. The line voltage should be between the selected voltage +8% or -10%. 1. Check the secondary voltage of the transformer. It should be less than 30VAC. If not, replace the transformer. 2. Check the DC voltage on the PCB. It should be less than 37VDC. 3. Replace the main PCB.

2.4. ERROR IN X-AXIS POSITION Cause: The drum motor cannot move to the required position. This is a fatal error. It can only be solved by turning the power off and then on again. This error is usually caused by a media crash in the machine. Action: 1. Remove the crashed vinyl and restart the machine. Should this happen rather frequently, the cause can be :  knife depth or pressure is not well set.  bad tracking because an unstabilised vinyl type is used.  bad tracking because the humidity is too high or too low.  bad tracking because an unapproved type of vinyl is used.  the vinyl hit something on the floor while cutting.  the vinyl shows already different tracks, so that the vinyl does not know which track to follow. 1. Lower the speed of the media. 2. Check whether the drive drum turns smoothly (first turn the power off and place the camrollers in the up-position). 3. If the error in the x-axis happens at start-up, check the x-axis motor, connectors and the cables.

4. Replace the X-motor encoder. 5. Replace the X-driver on the PCB (IC U2), or the small driver PCB for the second X-motor on the larger SummaSign machines.

6. Replace the PCB.

2.5. ERROR IN Y-AXIS POSITION Cause: The motor driving the knife head cannot move to the position wanted. This is a fatal error. It can only be solved by turning the power off and then on again. This error is usually caused by a media crash. Action: 1. Remove the crashed vinyl and restart the cutter. 2. Lower the speed and/or the knife pressure. 3. Check whether the head moves smoothly (first turn the power off and position the camrollers on the outer edges of the vinyl). 4. Check the y-axis motor and the encoder cables. 5. Replace the Y-motor. 6. Replace the Y-driver on the PCB. 7. Replace the PCB.

2.6. INTERNAL ERROR Action: 1. This is an internal line error of the 68000 microprocessor. The cause of this error may be an unknown firmware problem in the machine's EPROMs. Do the internal confidence test. If this test is OK, check the data sent to the cutter. Start with sending data that gave no problems in the past. 2. Reflash the ROM’s in the PCB. 3. Replace the main PCB.

2.7. NVRAM FAILURE Action: It is then still possible to work with the cutter, but the cutter has been defaulted to a D610. As the nvram has been defaulted to a D610, the margins and the calibration will be incorrect! The correct machine type can be set with SummaCutter Control program. Calibration and margins will then also be reset.
