5 .9 .2 Switching Outputs
5 .9 .2 .1 Operation Cycles S1/S2/S3/S4
The number of operation cycles per switch output is indicated.
An operation cycle is a complete change of the switch state till back to the start state, thus deactive -
active - deactive.
5 .9 .2 .2 Runtime S1/S2/S3/S4
The runtime per switch output is indicated.
The runtime of each switch output can be reset here separately.
At the pump function runtime, this is especially necessary after a pump exchange, to include the new
pump into the runtime dependent activation.
5 .9 .3 Failure
The device registers multiple of short time or also continuous existing functional failures in type and
frequency of occurrence.
•
Echo lost
No measurable echo signal available
•
Over Range
exceeding the signal output range (dependent on Operating Mode)
o
20.5 mA (4-20 mA)
o
20.5 mA (0-20 mA)
o
10.5 V (0-10 V)
•
Under Range
exceeding the signal output range (dependent on Operating Mode)
o
3.8 mA (4-20 mA)
o
-0.4 mA (0-20 mA) – theoretical value
o
-0.5 V (0-10 V) – theoretical value
•
Sig . out break
wire break at signal output on signal output not connected at Operating Mode 4-20 mA resp.
0-20 mA
5 .9 .4 Error Messages
The type of failure, that leads to the device reactions
•
Indication on display
•
Error signal at analogue output, depending on selected operating mode
•
Error function at switching output, depending on settings
can be selected.
The following failures can be selected:
•
Output overflow
Overshoot of the analogue output range OutA1 depending on selected operating mode
o
Operating mode 4-20mA >> 21mA
o
Operating mode 0-20mA >> 21mA
o
Operating mode 0-10V >> 10,5V
Default > activated
