Complete Operating Menu / Description
Pause Normal
If the pause switch is off, the DULCOMETER
pause switch is off or for a set time delay t
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 Tn > 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
delay t
must be set up in such a way that during this time e.g. sample water (process-specific current
d
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
P-component and (if Tn is set > 0) with the stored I-component.
Pause Hold
If the pause switch is off, the DULCOMETER
as long as the pause switch is off or for a set time-delay t
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
delay t
must be set up in such a way that during this time e.g. sample water (process-specific current
d
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
P-proportion and (if Tn 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
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.
