B&C Technologies M720 Dryer Control (DE, DP, DI Series) - Manual (Page 22)

drying program has its own counters. The second and third set are for a counter set per day
(Counters Per Day) and counter set with totals of all programs and all days (Counters In Total).
The fourth set is a non-resettable counter set, used to read counters processed since the controller
was fabricated.
4.4.1 Counters per Program
With the counter set Counters Per Program the user can read how many batches and how many
operating minutes have been done in a certain program. If Counters Per Program is chosen from
the counter menu, the counters of the current active program will be displayed. On the 1
st line the
number and name of the program can be seen. The 2 nd line has the name of the counter, followed
by the value of the counter.
With the P LUS and M INUS buttons the counters of the next and previous program can be viewed.
Scrolling through the available counters per program is done with the A RROW U P and A RROW
D OWN buttons. There are 2 different counters:
• Number of batches
The number of batches processed in this program since the last reset
• Running minutes
The number of minutes a program cycle has been active using this program since the last
reset
Resetting the counters of a program can be done by pushing the C LEAR key (S HIFT key and E NTER
key together). Depending on the adjustment in machine parameter 16, the controller may ask for
a password. Password level 1 is necessary to be able to reset the counters of a program. If the clear
key is pressed and the password level is sufficient, all counters of this program will be set to 0.
4.4.2 Counters per Day
With the counter set Counters per day, the user can read how many batches and how many oper-
ating minutes have been done on a certain day. The controller saves the production data of the last
50 days the machine has been used. After 50 days, the oldest record will be deleted and replaced
by a record of the current date.
If, in the Counter menu the item Counters per day is chosen, the counters of the current day will
be displayed. On the 1
st line, the date can be seen in DD-MM-YYYY format. With the P LUS and
M INUS buttons, the counters of the next and previous day can be viewed. With the A RROW U P
and A RROW D OWN buttons, one can scroll through the available counters per day. In this case
there are 2 different counters:
• Number of batches
The number of batches processed this day
