MR tapcon 240 - Setting lower limit value; Setting lower limit value of input signal

7 Functions and settings
Maschinenfabrik Reinhausen 2014110 222/08 ENTAPCON® 240
The device is configured at the factory according to the order. However,
should modifications be necessary, note the following sections.
The analog input card is used to record the tap position of an analog signal
transmitter. Depending on device configuration, you can capture the follow-
ing signals:
AD card AD8 card
Resistor contact series 50...2,000 ohms not possible
Injected current 0/4...20 mA 0/4...20 mA
Table 25: Analog tap position capture
Setting lower limit value
You can use these parameters to set the lower limit value for the tap posi-
tion . To do this, you must set the lower value of the signal range and the
linked lowest tap position.
You can undertake the settings for each input on the analog input card.
For example: To capture a tap position range of 1...19 via input 1 as
4...20 mA, you must set 20 % for the "Input 1 lower limit" parameter and 1.0
for the "Input 1 lower value" parameter.
Setting lower limit value of input signal
To configure the analog input, you must state the lower limit value of the in-
put signal. Use the following settings depending on your analog signal:
Analog signal Setting
Injected current: 0...20 mA 0 % (= 0 mA)
Injected current: 4...20 mA 20 % (= 4 mA)
Resistor contact series always 20 %
Table 26: Parameter settings
To set the lower limit value of the input, proceed as follows:
1. > Configuration > Continue > Analog inputs.
ð Input 1 lower limit.
2. Press to highlight the position.
ð The desired position is highlighted and the value can be changed.
3. Press to increase the value or to reduce it.
4. Press .
ð The lower limit value for the tap position is assigned.
