SEAL 44Ultra Laminator, SM110EN service manual Cause

Problem:

The power LED does come on, but it is flashing at a low rate. This is an error-condition.

Cause:

The supply voltage is too low.

Problems like these occur usually if extension cords are used; in particular extension cords, that have a (too) low rating. When the heater of the machine is switched on, the voltage usually drops.

Solution:

Do not use extension cords.

Check if the power supply of the office/building, where the 44 Ultra is used, supplies enough voltage to power the machine.

For the 110V unit, the supply voltage should lie between 90V and 130V. For the 230V unit, the supply voltage should lie between 200V and 250V.

Problem:

The power LED does come on, but it is flashing at a high rate. This is an error-condition.

Cause:

The supply voltage is too high.

Solution:

It’s not likely that this error will occur; however, you should check the rating label. If this is a 110V unit that’s attached to a 230V supply, the F1 and/or the F2 fuse should blow.

For the 110V unit, the supply voltage should lie between 90V and 130V. For the 230V unit, the supply voltage should lie between 200V and 250V.

Problem:

The LED for the Photoelectric Cells on the control panel does not come on; the machine does not run forward.

Cause:

An object is interrupting the lightbeam.

Solution:

Remove the Image Guide (if applicable); check if something is sticking on the edge of the infeed table (a piece of paper or tape).

The Photoelectric Cells are misaligned.

Solution:

Perform the adjustment procedure described in Section 5-4.

The Photoelectric Cells are defective. The green LED on the receiving photocell does not come on at all, when the transmitter is set to its maximum position (see Section 4-6).

Solution:

Replace the Photoelectric Cells as described in Section 4-6. Next, perform the adjustment procedure described in Section 5-4.

The Control System Board is defective. This is the case if the adjustment procedure is functional, but the green LED on the panel still does not come on.

Solution:

Remove the rear panel as described in Section 4-3, and replace the Control

System Board.

Problem:

The LED for the Photoelectric Cells on the control panel is flashing.

Cause:

The internal self-check signal for the photoelectric cells is not present.

Solution:

Remove the rear panel as described in Section 4-3, and replace the Control

System Board.
