OPERATING AND PROGRAMMING INSTRUCTIONS
NOTE: Before attempting to start the dryer make sure that the main door is closed and the lint
drawer is securely in place.
Microprocessor (Computer) Dryer
1. General description of the controller
The DQ 01 is a user configurable microprocessor controller used to control drying
machines. Because of the versatility of the software, it can be used in almost any type of dryer,
without the need to modify the software.
The controller has the following features:
-
192 x 32 pixels display, fully graphically controlled.
- 3 large 7-segment displays to indicate estimated time left and alarms.
- 20 buttons with “cap-sense” technology. These buttons work with capacitive
measurement, without any moving parts so increasing reliability.
- 100 different drying programs, each with an own name of up to 32 characters to indicate
the type of program.
- 16 digital optically isolated inputs, 24VAC or 24VDC.
- 8 digital relay outputs, up to 250VAC, 8A.
- 2 probes for temperature measurement.
- 1 analogue output for controlling the drum speed in cases where a frequency inverter is
used.
- Possibility for automatic drying with optional 2
nd
temperature sensor, infra-red sensor or
humidity sensor.
- Up to 8 extension boards, each with 8 inputs and outputs can be used to extend the
number of inputs and outputs if required.
- Power supply 24VAC or 24VDC.
- RS485 communication port for communication with PC for up- and downloading
parameters, translations, character sets, etc.
- Power supply monitoring. In case the power supply drops below or rises above a certain
limit, the controller will switch off all outputs and give an alarm message.
- Full worldwide character set, including Chinese, Japanese, Thai, Russian, Arabic and
Greek characters.
- Possibility to store up to 50 different languages.
- No parameter settings will be lost in case of power supply failure or an empty battery.
- Self-configurable start-up logo, which can be used to customize the controller.
- Possibility to edit and add languages with the use of free software.
- Extended test programs which allow the user to monitor and control each input/output
individually.
- Counters per program, total counters and counters per day. The production data of the
last 50 days is stored.
- Alarm history which records the last 50 alarms and messages, this history is battery
backed up so service engineers can track malfunctions even if the controller has been switched off.
