WARNINGS
Get
[i:51][CR][LF]
[i:51][abcdefgh][CR][LF]
data length 8 characters
a 0 = no service required
1 = service request, it is indicated when the control unit detects that
motor steps are apparently not effective. This may happen when the valve
is heavily contaminated or the gate seal is heavily sticking. These ‚lost‘ steps
are recognized and will be repeated to attempt target position in the short
term. But in the medium term the valve requires cleaning or inspection.
b 0 = LEARN data set present, 1 = LEARN data set not present
c 0 = power failure battery ready
1 = power failure battery not ready
defgh reserved, do not use
This function returns warning information about the valve. If a warning is present
countermeasure should be taken. Use RESET command to delete service request bit.
Note: Without LEARN the valve is not able to run pressure control
SENSOR OFFSET
Get
[i:62][CR][LF]
[i:62][aaaabbbb][CR][LF]
data length 8 characters
aaaa offset sensor 1 (-140 ... 0140 = -1.40V ... +1.40V)
bbbb offset sensor 2 (-140 ... 0140 = -1.40V ... +1.40V)
This function returns the sensor offset voltages for both sensors (adjusted by ZERO).
SENSOR 1 OFFSET
Get
[i:60][CR][LF]
[i:60][xxxxxxxx][CR][LF]
data length 8 characters
xxxxxxxx offset sensor 1 (-1400000 ... 01400000 = -1.400000V ... +1.400000V)
This function returns the sensor 1 offset voltage (adjusted by ZERO).
SENSOR 2 OFFSET
Get
[i:61][CR][LF]
[i:61][xxxxxxxx][CR][LF]
data length: 8 characters
xxxxxxxx offset sensor 2 (-1400000 ... 01400000 = -1.400000V ... +1.400000V)
This function returns the sensor 2 offset voltage (adjusted by ZERO).
