B&C Technologies M720 Dryer Control (DE, DP, DI Series) - Manual (Page 24)

As the name suggests nonresettable counters cannot be reset. Also they are saved in EEPROM
memory and not in battery backed-up memory. This means that, unlike the other 3 counter sets,
these counters will not be lost when the battery fails or is removed.
4.5 Edit Parameter Menu
The controller has 3 sets of parameters. There are parameters which can be programmed specif-
ically for a drying program, so a program can be set-up to process a specific material. These are
the program parameters. The machine parameters are general parameters which are always used,
regardless of the active program. Configuration parameters are parameters which describe the op-
tions in the machine and are typically set by the manufacturer. Program parameters and machine
parameters can be accessed via the Edit parameter menu item in the main menu. Configuration
parameters can be accessed via the separate item Edit configuration parameters in the main menu.
The Edit parameter menu is also used to change the name of a program.
If, in the main menu, the item Edit parameter menu is selected, this menu will be activated. In this
menu, an item can be selected with the A
RROW U P and/or A RROW D OWN key. Confirming the
choice of an item must be done by pressing the E NTER key.
4.5.1 Edit Program Parameters
The program parameter list is a list of parameters which can be programmed to create a specific
program. The parameters in this list are only used in the current program. To edit program pa-
rameters, password level 1 (1234) is required.
Before entering into programming mode, select the program that needs editing on
the keypad. For example, if you wish to edit program 19, press the 1, then the 9 key,
then ENTER so that 19 shows on the display. Alternatively, use the up and down
arrows to navigate to the appropriate program.
In the Edit Program Parameters screen, each different parameter can be selected with the up and
down arrow keys. A value can be changed with the plus and minus keys, or with the numeric
keys. Changing the value must be confirmed by pressing the enter key. The upper line will show
the number and name of the parameter, followed by the value.
On the lower line, the maximum and minimum limits will be displayed. The icon indicates if it
is possible to move up or down in the list, and the icon is displayed to indicated if it is possible
to increase or decrease (change) the selected value.
If the S HIFT key is used in combination with the A RROW U P or A RROW D OWN the controller will
move to the first or last item in the list. If the S HIFT key is used in combination with the P LUS or
M INUS keys, the value will be increased and decreased in larger steps. Refer to Figure 4.2 on page
22 for details.
The following program parameters are available:
