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).

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.
