Standard 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 t
d
(if t
d
is set to > 0 min). Whilst the pause switch is off, the D1C
establishes the P-proportion in the background.
With PID control (Identity code characteristics “control characteristic” = 2): the I-proportion is stored when
the pause is switched off (I-proportion 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 t
d
. The time
delay t
d
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 t
d
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 t
d
(if t
d
is set to > 0 min). Whilst the pause switch is
off, the 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 t
d
. The time
delay t
d
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 t
d
is reconciled jointly with the current
P-proportion and (if Ti is set > 0) with the newly established I-proportion.
Access Code
Access to the setting menu can be prevented by setting up an access code. The DULCOMETER
®
D1C
controller is supplied with the access code 5000 which permits free access to the setting menu. The
calibration menu remains freely accessible even if access to the setting menu is blocked by the code.
