Control Overview
The M720 is a user configurable microprocessor controller used to control dryers. Because of the
versatility of the software, it can be used in almost any type of dryer, without the need to modify
the software.
2.1 Features
The controller has the following features:
• 192 x 32 pixels display.
• 3 large 7-segment displays to indicate estimated time left and alarms.
• 20 buttons with cap-sense technology. These buttons work with capacitive measurement,
with no moving parts which increases reliability.
• 100 different drying programs, each with its own name of up to 32 characters to indicate the
type of program.
• 16 digital optically isolated inputs.
• 8 digital relay outputs, up to 250VAC, 8A.
• 2 probes for temperature measurement.
• 1 analog output for controlling the cylinder speed in cases where an inverter is used.
• Optional automatic drying with optional 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.
• RS485 communication port for communication with PC for transferring parameters, transla-
tions, character sets, etc.
