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 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 de-activating 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
Index: [0] = AI0 (T. 3/4)
[1] = AI1 (T. 10/11)
[2] = AI2 (T. 50/51)
[3] = AI3 (T. 52/53)
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.
Note: When changing p0756 , the parameters of the scaling characteristic (p0757, p0758, p0759, p0760) are overwritten
with the following default values:
For p0756 = 0, 4, p0757 is set to 0.0 V, p0758 = 0.0 %, p0759 = 10.0 V and p0760 = 100.0 %.
For p0756 = 1, p0757 is set to 2.0 V, p0758 = 0.0 %, p0759 = 10.0 V and p0760 = 100.0 %.
For p0756 = 2, p0757 is set to 0.0 mA, p0758 = 0.0 %, p0759 = 20.0 mA and p0760 = 100.0 %.
For p0756 = 3, p0757 is set to 4.0 mA, p0758 = 0.0 %, p0759 = 20.0 mA and p0760 = 100.0 %.
For p0756 = 6, 7, p0757 is set to 0 °C, p0758 = 0.0 %, p0759 = 100 °C and p0760 = 100.0 %.
Description: Sets the scaling characteristic for the analog inputs.
The scaling characteristic for the analog inputs is defined using 2 points.
This parameter specifies the x coordinate (V, mA, °C) of the 1st value pair of the characteristic.
Index: [0] = AI0 (T. 3/4)
[1] = AI1 (T. 10/11)
[2] = AI2 (T. 50/51)
[3] = AI3 (T. 52/53)
Note: The parameters for the characteristic do not have a limiting effect.
