OPERATION OF ELECTRONIC CONTROL
(MODEL UDTM - UDLM)
4.1.
Principle and description of the control of the machine
The machine is controlled using an electronic microprocessor able to control the activation and
deactivation of the different inputs and outputs of the system. Communication with the user is carried out
using a keypad with keys and indicator lights (LED) which indicate the states of the machine. The control
can be configured for operation in
OPL mode
or in self-service mode. In addition, it is possible to modify
certain operating parameters of the control using
the ELECTRONIC CONTROL console
(sold
separately).
A digital temperature probe, located in the bottom of the drum is used to keep the temperature constant
inside the dryer. The required temperature is selected using three keys for three levels: low, medium and
high. This allows the machine to be used at the optimum temperature for each fabric type.
The electronic plate receives the signal from the temperature probe and activates or deactivates the heater
element to adjust the temperature.
Time control is internally carried out in the microprocessor. In
OPL
mode, two keys can be used to increase
or decrease the drying time. The time entered is displayed on a scale of indicator lights (LED). If the
machine is configured in self-service mode, these keys are not used and the time is increased according
to the payment made.
The control includes a Cool-down time (progressive cooling) which starts at the end of the drying cycle.
The anti-crease cycle is automatically activated at the end of each cycle ( Cool-Down) in
OPL
mode. If the machine is configured in self-service mode the anti-crease cycle will not be run.

ELECTRONIC CONTROL:
POSITIONS:
1. Start/Stop button.
2. Run (green) or alarm/warning (red) indicator light. For further information, see the section Alarms
and Warnings.
3. Keys for increasing or decreasing the drying time (OPL mode). Each time the key is pressed is the
equivalent of 5 minutes in time.
4. Programmed drying time remaining indicator lights.
5. Temperature selection keys (High, medium or low).
6. Temperature selection indicator light (High, medium or low).
