ABB TZIDC-220 Electro-Pneumatic Positioner V18350 Positioner
Overview
The TZIDC-220 positioner has a special function for automatic
adjustment of the parameters. The function is launched either via the
integrated operator’s panel or the user interface.
The following adjustment parameters can be activated and
configured:
Parameters for control block
To optimally adjust the actuator position, the control parameters can
be set individually for the control behavior of the valve.
Range 0 ... 100 %
Configuration of end positions for the valve to be adjusted to start
position “0” and end position “100 %".
Direction of the actuator
Calibration to both possible directions of action:
Air opens / spring force closes
or
Air closes / spring force opens
Display 0 … 100 %
Adjusting the display (0 ... 100 %) to the direction of action for opening
or closing the valve.
3.1.3 Monitoring parameters
B
Various functions for permanent operational monitoring are
implemented in the TZIDC-220 operating program, e.g.:
- Internal positioning time-out
- Sensor monitoring
- Backup monitoring
The TZIDC-220 positioner’s operator panel with four pushbuttons
allows for
- operational monitoring
- manual control
- configuration
- fully automatic commissioning
The operator panel is protected by a hinged cover which can be
opened during operation even in hazardous areas, i.e. the positioner
can be locally operated any time as required.
The four pushbuttons enable users to select operating levels,configure the device and store settings. In addition to the known operating functions, a simplified autoadjust can be performed. This enables you to launch the device’s automatic configuration function in a few steps and without detailed knowledge regarding parameters.When changing the actuator type from linear to rotary, the zero position of the display is automatically updated. This is indicated in the display for valves closing on the right in the closed position 0 %.
