B&C Technologies M720 Dryer Control (DE, DP, DI Series) - Manual (Page 40)

• Value 0: Output on when a drying cycle or cool-down cycle is busy. In this case the
output will be switched on when a drying cycle starts and will switch off when the
program is finished. This means that the output will always be on, even if the machine
is stopped by an alarm or by the user, until a program is completed.
• Value 1: Output on when a program is finished. If a program has been finished, the
output will be switched on and will stay on until the door is opened or until the program
cycle is stopped by pushing the stop key twice.
• Value 2: Output on when the machine is stopped because of an alarm while a drying
cycle or cool-down cycle was active.
• Value 3: Output on when a program is finished (see value 1) or when an alarm is active
during a program cycle (see value 2).
8. Rotation sensor
This parameter indicates if the machine is equipped with a rotation sensor. If so the rotation
sensor should be connected to input 7. Please note that the rotation sensor must be a 24VDC
sensor as the use of 24VAC sensors is not possible. If this parameter is set to Yes, the machine
will monitor the sensor when the drum is running. If the drum is running and the rotation
sensor has not been detected for a given time interval (see Section 4.5.3, item 26) the machine
will be stopped and an alarm will be displayed.
9. Jog Buttons
This parameter indicates the presence of jog buttons. If set to Yes the jog buttons should
be connected to inputs 12 and 13. Jog keys allow the user to jog the drum motor when the
machine is in a stop situation, the emergency stop is not active and the door is closed. If
the drum motor is controlled by an inverter a separate motor jog speed can be defined with
machine parameter 27.
10. EDG replacement
If the controller is to replace an existing EDG controller, this parameter has to be set to Yes. If
set to Yes, the machine will perform other checks on the filter door/drawer open input and
the overload input. This has to be done so the controller can be replaced by just using the
existing connectors without the need of changing the wiring of the switches.
Setting this parameter to Yes also overrules the function of the inputs 8, 9, 10 and 15 (air
pressure switch, overheating contact, emergency stop/safety switches and fire suppression
input). This means that if an EDG controller is replaced with an M720 controller in an existing
machine, this parameter has to be set to Yes and these inputs will not be monitored.
Please note that if an EDG controller is replaced by an M720 dryer controller, the temperature
sensor should also be replaced.
4.10 Controller Information
The Controller information screen shows the current hardware and software version, and the serial
number of the controller. This information can, for example, be used to check if the correct version
