to confirm change, followed by after all changes are made.
The following configuration parameters are available:
1. Startup logo nr.
When the controller starts up a start-up logo will be displayed for 5 seconds. Depending on
manufacturer and distributor, it can be useful to change the start-up logo. If the value of this
parameter is 0, no start-up logo will be displayed.
2. Humidity sensor
This parameter indicates if a humidity sensor is present in the exhaust. This sensor is used
for automatic drying which means that the controller can measure if the batch is dry and stop
the drying cycle instead of running on a fixed (too long) drying time.
3. 2 nd temp. sensor
This parameter indicates if a 2 nd temperature sensor is connected. This means that an extra
temperature sensor is mounted at the air inlet of the machine. This sensor is used for auto-
matic drying, which means that the controller can measure if the batch is dry and stop the
drying cycle instead of running on a fixed (too long) drying time. If this sensor is present, it
is also possible to limit the inlet air temperature with machine parameter number 40.
4. Infra-red sensor
This parameter indicates if an infra-red sensor is available to measure the linen temperature.
The infra-red sensor is used for automatic drying, which means that the controller can mea-
sure if the batch is dry and stop the drying cycle instead of running on a fixed (too long)
drying time.
5. Reversable drum
This parameter indicates if the drum can turn left and right with a reverse relay. If this
parameter is set to yes, output 5 and 6 are used for the motor direction and in the program
parameters, parameters 13, 15 and 16 are used to adjust the motor direction, motor run time
and motor stop time.
6. Drum with freq.inv
This parameter indicates if the drum motor is controlled with an inverter. If so, the drum
speed can be controlled by connecting the analogue output of the controller to the analogue
input of the inverter. With program parameter 14 the drum speed can be programmed per
program.
7. Status output func
This parameter sets the function of the status output (output number 2), which can be used
to give a signal to an external system or for example to connect an alarm light.
