Complete Operating Menu / Description
Normal pause
If the pause switch is off, the DULCOMETER
®
D1C sets the operating outputs to “0“ for as long as the
pause switch is off or for a set time delay td (if td is set to > 0 min). Whilst the pause switch is off, the
DULCOMETER
®
D1C establishes the P-proportion in the background.
With PID-control (identity code characteristics “control characteristic“ : 2): the I-porportion is stored when
the pause is switched off (I-porportion then usually only present if Ti > 0 has been selected in the “control
setting?“ setting menu).
Exception: the standard signal outputs mA for the measured value or correction value are not affected by
the pause.
After pause is activated, the operating outputs remain at “0“ for the length of the time delay td. The time
delay td must be set up in such a way that in this time e.g. sample water (process-specific current
concentration) flows to the sensor.
With PID-control (identity code characteristics “control characteristic“: 2): The control variable output
resulting from the pause and the expiry of the time delay td is reconciled jointly with the current
P-component and (if Ti is set > 0) with the stored I-component.
Pause hold
If the pause switch is off, the DULCOMETER
®
D1C freezes the operating output at the most recent value
for as long as the pause switch is off or for a set time delay td (if td is set to > 0 min). Whilst the pause
switch is off, the DULCOMETER
®
D1C establishes the P-proportion in the background.
With PID-control (Identity code characteristics “control characteristic“ : 2):
Even the mA standard signal outputs for measured value or correction value are frozen.
After pause is activated, the operating outputs remain frozen for the length of the time delay td. The time
delay td must be set up in such a way that, in this time e.g. sample water (process-specific current
concentration) flows to the sensor.
With PID-control (identity code characteristics “control characteristic“: 2): The control variable output
resulting from the pause and the expiry of the time delay td is reconciled jointly with the current
P-proportion and (if Ti is set > 0) with the newly established I-proportion.
