Manual Configuration Of End Positions; Example - ABB TZIDC Manual

2 Manual configuration of end positions

Example

The following figure is a sample depiction of the operating range
of a TZIDC, TZIDC-200 after the parameters for the contactless
sensor in the positioner have been configured manually.
The following initial situation is assumed:
• The actuator uses spring force or ventilation to move
clockwise from OUT2 to an opening degree of 0%.
In order for the operating range of the positioner
(P6.0–MIN_VR, P6.1–MAX_VR) to be fully defined, the parameters
P6.7–ZERO_POS and
P6.3–SPRNG_Y2 must additionally be positioned toward the
relevant rotational direction during commissioning.
1 Device feedback shaft
2 Lever
A Operating range 100% opening degree, OUT1 = supply pressure
B Operating range 0% opening degree, OUT1 = ambient pressure
C Operating range of the valve/actuator, parameter "P6.0 – MIN_VR" and "P6.1 – MAX_VR".
For rotary actuators, the operating range within each position can be up to 340°.
D Rotational direction for parameter "P6.3 – SPRNG_Y2 = CLOCKWISE" (When venting OUT 1, the device feedback shaft 1 turns clockwise).
E Rotational direction for parameter "P6.7 – ZERO_POS = CLOCKWISE" (When venting OUT 1, the device feedback shaft 1 turns clockwise).
Figure 1: Measurement and operating range with contactless position feedback (example)
In this case, it applies to the following configurations:
P6.7 (ZERO_POS) = CLOCKWISE (Figure 1, Pos.
•
P6.3 (SPRNG_Y2) = CLOCKWISE (Figure 1, Pos.
•
Note
Depending on the relevant installation situation, the parameters
must always be determined and configured individually on site.
