Program Operation
In this phase the program cycle is running. A program cycle can be a drying step, a cool-down
step or both. When running, the 2
nd
line in the overview screen will show the current status (see
If an alarm occurs, the machine will be stopped by the controller and the program cycle will be
paused. The same will happen if the S
TOP
key is pressed.
When cause of the alarm has been corrected, the alarm can be reset with the S
TART
key. After that,
Waiting for cycle restart will be displayed. The same will happen if the S
TOP
key is pressed once.
If the message Waiting for cycle restart is displayed, the cycle can be restarted with the S
TART
key
and the pause situation is canceled. If, in this case, the S
TOP
key is pressed, the complete program
will be canceled and the step described in section 3.1 on page 10 is activated.
When the drying step and the cool-down step are finished, the step described in section 3.1.5 on
page 12 is activated.
3.1.5
Program Completion
This step is activated when a program cycle is finished. When the program cycle is completed, the
beeper will sound for the time defined in machine parameter 6 (see Section 4.5.3 on page 26). This
beeper sound will restart every 2 minutes.
After finishing a program the machine will either stop or the anti-crease cycle will start if selected.
The anti-crease function can be enabled or disabled in the program parameters (see Section 4.5.1
on page 21).
If anti-crease is enabled the machine will be stopped for 2 minutes after finishing a program cy-
cle. 2 minutes later, anti-crease function starts. This means that the drum direction and speed as
defined in the program will be used and the blower will be off.
Note: Because the blower output is off during anti-crease operation, the anti-crease function will
not work if the blower and the drum motor are both connected to output 7 during installation of
the controller.
If a cycle is completed, the dryer will stay in this step (audible signal and/or anti-crease opera-
tion) until the door is opened. When the door is opened, the controller assumes the dryer will be
emptied and will go back to the ready to start state as described in Section 3 on page 10.
