2.2 List of parameters
Value: 0: 1x2 wire evaluation
1: 2x2 wire evaluation
2: 3 wire evaluation
3: 4 wire evaluation
Index: [0] = X531
[1] = X532
[2] = X533
[3] = X534
[4] = X535
[5] = X536
Note: The temperature sensors are connected to the following terminals:
X531 = channel 0 (for 2x2 wire evaluation, additionally channel 6)
X532 = channel 1 (for 2x2 wire evaluation, additionally channel 7)
X533 = channel 2 (for 2x2 wire evaluation, additionally channel 8)
X534 = channel 3 (for 2x2 wire evaluation, additionally channel 9)
X535 = channel 4 (for 2x2 wire evaluation, additionally channel 10)
X536 = channel 5 (for 2x2 wire evaluation, additionally channel 11)
Re p4108[0...5] = 0, 2, 3 (1x2, 3, 4 wire evaluation):
The temperature channel belonging to the terminal block with the higher number is automatically deactivated (e.g. for
X531 with 3-wire evaluation, channel 6 is deactivated).
Description: Setting to start the measurement of the wire resistance for a channel for the Terminal Module 150 (TM150).
For a 2 wire evaluation, the total wire resistance is measured and saved. During the temperature evaluation, the
temperature actual value is automatically calibrated using the measured wire resistance.
Procedure:
1. Select the measuring method (1x2/2x2) for the corresponding terminal block (p4108[0...5] = 0, 1).
2. Set the required sensor type for the corresponding channel (p4100[x] = 1 ... 6, x = 0...5 or 0...11).
3. Jumper the sensor to be connected (short-circuit the sensor conductor close to the sensor).
4. Connect the sensor conductors to the appropriate terminals 1(+), 2(-) or 3(+), 4(-).
5. For the corresponding channel, start the measurement of the wire resistance (p4109[x] = 1).
6. After p4109[x] = 0, check the measured resistance value in p4110[x].
7. Remove the jumper across the temperature sensor.
Value: 0: Inactive
1: Start
Index: [0] = Temperature channel 0
[1] = Temperature channel 1
[2] = Temperature channel 2
[3] = Temperature channel 3
[4] = Temperature channel 4
[5] = Temperature channel 5
[6] = Temperature channel 6
[7] = Temperature channel 7
[8] = Temperature channel 8
[9] = Temperature channel 9
[10] = Temperature channel 10
[11] = Temperature channel 11
Dependency: Refer to: p4100, p4108, p4110
Notice: Wire resistance measurement is only possible for 1x2 or 2x2 wire evaluation (p4108[0...5] = 0, 1).
Note: The wire resistance value can be also directly entered into p4110[0...11].
The automatic conductor calibration for 1x2 and 2x2 wire evaluation is always performed with the value in
p4110[0...11].
