PL265 ELECTRONIC INFORMATION
There are several reasons that the main logic board of an electro-mechanical unit could bounce into diagnostics. This is basically a logic error that is likely being caused by some unexplained electrical surge going to the electronics of the machine. Below, find the necessary information to logically work through the electrical system of the machine.
A bad connection in either area could cause a machine to have electronic glitches.
VOLTAGE REQUIREMENTS The machine requires at least 220 VAC, Single Phase. The voltage for the unit should not go below this number, and should not ever be more than 240VAC. Anything less than the 220VAC that are required could cause the machine to have this kind of issue. If the power is too low, a buck/boost transformer would have to be installed to get the voltage to the proper level. If the voltage for the machine is too high, this problem could also occur, and the power would have to be reduced through the same method, but with different wiring.

COMMON ERRORS On occasion, it is necessary to create a single-phase outlet from a triple phase power supply in order to install a machine of this kind. This opens the possibility for a mistake when choosing the appropriate lines to create the outlet. There are typically three live wires and a ground in a triple phase supply(Delta Configuration)and because of the nature of the electricity one of these lines will be much more(30-40VAC)than the expected 120 volts. This line should not be used, It is referred to as a” wild leg.” The result would be one line carrying an increase in voltage over the other one, and could cause a machine to malfunction. In order to verify that this is not the case the following electrical reading should be taken from the outlet. 1.) Take a reading from the left line to ground. You should have approx. 120 VAC. 2.) Take a reading for the right line to ground. The reading should be the same. 3.) Take a reading on the outlet for line to line. The reading should be 220VAC minimum/240VAC maximum. If these are not the readings found, the power supply would have to be corrected in order for the machine to function properly. INTERFERENCE ISSUES The unit should be on a dedicated power supply straight from the electrical box that it is wired into. This means that the outlet for the machine is the only one on the line, and no other machines would lose power if that breaker were to be thrown at the box. This is also an excellent method of finding out if that is the case. Turn on as many items as possible and see if any of the lose function when you turn off the breaker. If the machine is not on a dedicated supply, it may be possible that this is still not the issue. However, if there is something plugged into this line that generates high frequencies(fax, copier, digital press, other cutters, folders etc.)this very well could be the source of the problem, and would have to be corrected for the machine to function normally. LOGICAL TROUBLESHOOTING To troubleshoot the machine, you would need to start with the incoming power supply at the terminal block, and work your way in. Begin by performing the following steps.
II
1.) Locate the terminal block where the incoming power cord comes into the unit. Take a reading for each of the two live lines coming in, to the chassis ground of the machine. Each should be 120VAC. Brown wire, incoming power leg.
Chassis ground is a green and yellow wire screwed to the plate with a Phillips head.
Light blue wire, incoming power leg.
2.) Power down the machine, disconnect from the wall, and tighten each of the screws on the incoming terminal block. Also, tighten all screws in k1, k2, k3 and k4 relays(see photo)
3.) Locate the connection JXFMR on the main logic board. There are two transformers that supply power to the logic board. Take a reading with the machine turned on. Pins 1 and 3 should provide a minimum of 24VAC. Pins four and five should provide at least 8VAC, but no more than 15VAC(see photo)
Plug two Brown wires from 8 VAC transformer into the two far left receptacles.

4.) If more than 15VAC are found, the transformer can be wired around, and that power reduced. This would be done by disconnecting the two output wires from the small transformer and plugging them into the two far left terminals on the 24VAC transformer. See circles in photo above. 5.) Once it is verified that normal power is going to the main logic board, the display for the machine would need to be checked. Remove the display box from the machine, and verify that the four small nuts that hold the assembly in place are tight, and that there does not appear to be any defects in the keyboard.
Check all bolts holding the display assembly inside control box.
6.) If these items are intact, make a close inspection of the cables for the machine, and make sure that there are no breaks of any kind. Any damaged cable, however small the damage, should be replaced. 7.) Once each of these items have been verified, jumper around both of the in-line power filters and test the machine. If this corrects the problem then one of the filters has been damaged. Jumper independently to see which one is causing the trouble.
Apply jumpers to both sides as shown above to eliminate power filter from circuit.
