Allocation of the alarms to a certain actuate value
As it is not always desired that alarms follow the operating mode, the outputs
can be assigned to the minimal-/maximal value or any other value. Therefor
the adjustable value range is assigned to the according program number
(PN60, PN70, PN80 and PN90).
Modus
Actuate value
0 none
1 Instaneaous value
2 Minimal value
3 Maximal value
4 HOLD value
5 Sliding average value
6 Totalizator value
Alarm confirmation
If one wants to display interim occured alarms, the self-acting switching-on or
switching-off can be blocked. Therefore the confirmation of the according
setpoints 1-4 must be assigned to the digital input or the multi-function key
under program numbers 67, 77, 87 and 97.
Information
Alarm status will get lost by voltage drop!
Optical response, flashing display
If one or some thresholds are broken, the flashing of the alarm LED can
amplify the optical response by assignment of the threshold (PN59) to the 7
segment display.
Example:
The threshold for flashing of the display is set at setpoint 2. If
setpoint 1 is exceeded and set point 2 is not, the set point LED
1 lights up permanently. If setpoint 2 exceeds the threshold, the
7-segment display will start to flash, setpoint 1 will light up
permanently and set point LED 2 will flash. The flashing
enhances the optical response and the operator sees
immediately that an important threshold has been exceeded
with this unit.
