Description: Displays the currently referred input value of the analog inputs.
When interconnected, the signals are referred to the reference quantities p200x and p205x.
Index: [0] = AI0 (T. 3/4)
[1] = AI1 (T. 10/11)
[2] = AI2 (T. 50/51)
[3] = AI3 (T. 52/53)
Note: AI: Analog Input
T: Terminal
Description: Sets the type of analog inputs.
p0756[0...1] = 0, 1, 4 corresponds to a voltage input (r0752, p0757, p0759 are displayed in V).
p0756[0...2] = 2, 3 corresponds to a current input (r0752, p0757, p0759 are displayed in mA).
p0756[2...3] = 6, 7, 10 corresponds to a resistor input for temperature measurement (r0752, p0757, p0759 are
displayed in °C).
p0756[2...3] = 8 No temperature sensor connected. Mode for deactivating sensor monitoring (alarm A03520).
In addition, the associated DIP switch must be set.
For the voltage input, DIP switch AI0/1 must be set to "U".
For the current input, DIP switch AI0/1 or AI2 must be set to "I".
For the temperature input, DIP switch AI2 must be set to "TEMP".
Value: 0: Unipolar voltage input (0 V ... +10 V)
1: Unipolar voltage input monitored (+2 V ... +10 V)
2: Unipolar current input (0 mA ... +20 mA)
3: Unipolar current input monitored (+4 mA to +20 mA)
4: Bipolar voltage input (-10 V ... +10 V)
6: Temperature sensor LG-Ni1000
7: Temperature sensor PT1000
8: No sensor connected
10: Temperature sensor DIN Ni 1k (6180 ppm / K)
Index: [0] = AI0 (T. 3/4)
[1] = AI1 (T. 10/11)
[2] = AI2 (T. 50/51)
[3] = AI3 (T. 52/53)
Dependency: Refer to: A03520
Warning: The maximum voltage difference between analog input terminals AI+, AI-, and the ground must not exceed 35 V.
If the system is operated when the load resistor is switched on (DIP switch set to "I"), the voltage between differential
inputs AI+ and AI- must not exceed 10 V or the injected 80 mA current otherwise the input will be damaged.
