Read measured value at channel 14 once
If bit 3 of main control byte 4 is set, channel 14 is read once instead of channel 13.
The request bit and the acknowledgement bit (status byte 1, bit 3) are reset by the IP. After entering
the actual value and the error byte, the acknowledgement bit is set to 1.
The reaction time from setting the request to setting the acknowledgement bit is as follows:
– outside the pressure curve 55 – 110 ms
– within the pressure curve 55 – 220 ms
Note on tolerance monitoring:
The entry of the setpoint is in the units of the conversion factor specified in message 14, bytes 0/1.
The setpoint is limited to the conversion value internally. Tolerances cannot be selected. The
tolerances are calculated as follows:
– positive tolerance = 1.5 % conversion value, but minimum 2 units
– negative tolerance always 2 units.
3.4.6 Miscellaneous
The functions
– self-tuning
– cascaded control
can still be used.
The control bits ”read channel 13” and ”read channel 14” are irrelevant.
