2) Adjusting the gap between input table and main roll

The gap between main roll and input table can be adjusted by pins coming out from the input table. To adjust: follow the procedure on the previous page, except for bolt B1.

To move the pins forward: screw B3 until desired. To move the pins backward: unscrew B3.

Tighten bolts B2.

Description of the control system

General description of the control system

The control system consists of a microprocessor board with built-ondisplay andpush-buttons.

Electric heating control

For the electric heated version, the relays for the heating elements are controlled by a time related P.I.D. controlled function built in the program of the processor, which has the opportunity of a quick reaction with limited overshoot. The elements are activated by relays.

Gas heating

With the gas version, a PWM controlled ventilator is used, which is controlled by the microprocessor.

This ventilator blows the mix of gas and air into the burner, which means that the power of the burner is controlled by the microprocessor. The advantage is that also here the burner is controlled with a P.I.D. controlled function from 20-40to 100% so that there is a quick reacting system with a low overshoot.

When the need of power is lower than 15%, the burner will be temporarily switched off.

Temperature control

The temperature of the roll is measured by Pt1000 elements that are mounted on a contact plate on the roll. The Pt1000 are directly connected to the microprocessor board.

To prevent overheating when there is a malfunction of the Pt1000 or the microprocessor board,

a maximum temperature switch is placed, which switches off the power of the relay of the elements or the power of the gas control unit.

temp1: right sensor

Control of exhaust ventilator

The exhaust ventilator always turns on maximum when the ironer is switched on. An underpressure switch is mounted, which controls the working of the exhaust ventilator. The function of this underpressure switch is controlled when starting up the machine and will give a warning sign when the function is not correct.

Speed control

The speed is controlled by means of a frequency regulator, which is controlled by a feedback system through the microprocessor board.

The speed is checked by an approximated switch, which is activated by the teeth of a detection wheel.

Start/stop function

The ironer can be started and stopped by pressing the 0/I button.

The foot pedal can temporarily stop the ironer.

Control panel and function keys

The machine is equipped with the following operating devices:

1: Emergency stop button 2: Reset gas

3: Start/stop button 4: “+” Button

5: “-“Button

6: Return button

7: Left display (temperature) 8: Right display (speed)

When the power is switched to the machine by the main switch, “” and the program version will appear during 5 seconds.

Then the left display will give the actual temperature (in °C or °F) and the right display will give the actual speed (in M/min).

Menu structure and how to enter

After installation, each ironer needs to be configured.

There are 2 different systems: Manual and Coin version.

Manual version

When the main switch is switched on, "" appears on the right display during 5 seconds.

To enter the adjusting menus, press the I/0 button and ↓ button simultaneously until "" appears on the right display. With the + and - button, it is possible to switch between the menus,and

Menu structure

When the main switch is switched on, "" appears on the right display during 5 seconds.

To enter the adjusting menus, activate the microswitch inside the coin box casing.

When "" appears, keep pressing the microswitch (approximately 5 sec.) until "" appears on the display. Then press the “I” button to reset the emergency stop, after which the blinking "" menu will appear on the right display.

Then press the hidden ↓ button until 3 blinking dashes appear on the left display (approximately 2 sec.).

Release the ↓ button and press the microswitch again (approximately 5 sec.) until "" lights up on the right display.
