5.6 Function alarm output
The DPC200 has an open collector alarm output; depending on the operating mode the
function is different.
At the alarm event a contact between terminal no. 7 and no. 8 gets low-resistive and
can be loaded with a maximum of 30 V DC/ 30 mA. When the alarm is switched off the
contact will be high-resistive.
During alarm state in the control mode / measuring mode an exclamation point is displayed
(2nd line / 16th character).
Control mode:
In order to recognize the limits of control, the alarm output in the control mode refers to
the set maximum output voltage (MaxU
voltage".
In the default setting the value is set to 10 V DC.
Alarm ON: Output voltage for 12 seconds constantly greater than: 0.95 • MaxU
Alarm OFF: Output voltage for 12 seconds constantly less than:
Measuring mode:
For limit value monitoring a limit value can be entered. This value is set in the menu item
„limit switch". The previously set parameters are taken into account (unit, parameter,
k-factor and the measuring range).
In the default setting the limits are not active. Display 2nd line: „OFF"
Alarm ON: Measurement for 12 seconds constantly greater than 1 • limit value
Alarm OFF: Measurement for 12 seconds constantly less than 0.95 • limit value
