consuming process, the normal program cycle can be halted for a while. During the time needed to
restore all factory settings, the beeper will sound continuously.
Please note that restoring factory settings will restore the factory settings of all drying
programs and the settings of the machine parameters. These parameters are set as described in
chapter 8. Restoring factory settings does not change the configuration parameters. They will not be
influenced by this operation.
6.6.4 Reset maintenance request
With machine parameter number 5 (see chapter 6.4.3) it is possible to set a maintenance
request count. For example, if machine parameter 5 is set to 500, and 500 batches are done the
display will show ‘Maintenance request’ before the machine can be started for a new program cycle
(see also chapter 7, Alarms). This ‘Maintenance request’ will be active until the message is reset via
the ‘System setup menu item ‘Reset maintenance request’. If this item is selected a special
password must be entered (see chapter 6.1). For resetting the maintenance request the password is
1111.
The remaining number of batches until the next maintenance request message is displayed
can be seen in the ‘non-resettable’ counter set, see chapter 6.3.4.
6.6.5 Enter unlocking code
In special circumstances it is possible that the control system locks itself. If the control panel
is locked, message 5 will be displayed. To unlock the controller again, it is necessary to enter an
unlock code. In the ‘Enter unlocking code’ screen, the serial number of the controller is displayed.
With this serial number, the machine manufacturer is able to determine the unlocking code which
should be used for this controller. When the controller is locked it will automatically show the
‘enter unlocking code’ screen after every restart.
6.7 Alarm history
The alarm history list can be viewed by selecting ‘Alarm history’ in the main menu. The
alarm history is a list with the last 50 alarms, warnings and messages which have occurred. The
alarm history is stored in the battery backed-up memory.
In the alarm history screen the upper line displays which record number is currently
displayed. Scrolling through the list of records is done with the ARROW UP and ARROW DOWN
buttons. The maximum number of items saved is 50.
The time the alarm started is shown on the right side of the upper line. The lower line shows
the alarm number and alarm text (see chapter 7 for a complete list of all available alarms, warnings
and other messages).The number of minutes the alarm has been active is displayed on the right side
of the lower line. The maximum value is 240. When an alarm is active for longer that 240 minutes
(or 4 hours) the controller will stop counting. The minimum time is 1 minute. If an alarm is active
for less than 1 minute the number of minutes will be set to 1 anyway. If the alarm is still active, a
‘?’ will be shown instead of a value. If an alarm was active when the controller was switched off,
the active time will also show a ‘?’.
In order for the alarm history list work properly it is important that the controller date and
time are set to the correct values. Chapter 6.6.1 describes how to set the correct date and time.
6.8 Edit machine configuration
The machine configuration is a list of parameters which can be adjusted to set-up the
available options of the machine. Because these parameters influence the way the machine works
and because setting the wrong values can cause a complete machine stop, these parameters are only
