MAP Check 9000 - User Manual
4. Operation
Three-channel scanner
The third digit indicates whether MAP Check 9000 is equipped with an automatic three-
channel scanner. MAP Check 9000 automatically detects whether the scanner control unit
has been installed. The presence of this control unit is automatically detected when MAP
Check 9000 is switched on. If this digit is set to 1 and the scanner control unit was not
detected, error message no. 33 is presented and the digit remains 0.
Current output no. 2
The fourth digit indicates whether an extra current (or voltage) output has been fitted. This
extra output always provides the measuring signal. MAP Check 9000 cannot detect whether
an extra current output has been installed. Consequently, the first digit can be changed from
0 to 1, but the unit will not inform you about the missing current output.
4.12. MAP Check PFC
Use the built-in MAP Check PFC to add the menu P.P.C (Proportional Pressure Controller):
Then add the
dia.
menu (diagnostics) as the first menu item
reg.f
(Regulation flow) where
the current regulation flow can be read.
MAP Check PFC is set up in the following way:
PA.2
digit 4 = 0: normal MAP Check
PA.2
digit 4 = 1: normal MAP Check PFC
When
PA.2
digit 4 is set to 1,
PA.3
digit 1 must be set to 1 or 0 (with/without current output
no.1) to avoid confusion (MAP Check cannot control both a built-in proportional valve and the
external MAP Con).
PA.2
digit 1 has a higher priority than
PA.3
digit 1, which means that it is
ignored if
PA.3
digit 1 is set to 2 or 7 (MAP Con with/without by-pass).
4.12.1. Regulation parameters
The following parameters are used to control the gas regulation:
•
fl.in
: Flush in flow.
Enter as
lo/Hi.xx
. When online measuring starts, it will start with flush-in-flow. This flow is
maintained for del. seconds.
•
hi.o2/lo.o2
: Regulation window, upper/lower O
2
limit of the desired O
2
value.
Together, these two O
2
values form a window (upper and lower O
2
limit) which MAP Check
tries to keep the measured O
2
value within. If the measured O
2
value is higher than the
hi.o2
value, the proportional valve is opened until the measured O
2
value is below the
hi.o2
