Overview

General

ABB TZIDC-110 Positioner V18346 Positioner

Microprocessor-based position control in the TZIDC-110 provides for optimal results. The positioner features high-precision control functions and high operational reliability. Due to their elaborate

structure and easy accessibility, the device parameters can be quickly adapted to the respective application.ABB V18346 Positioner

The total range of parameters includes:

- Operating parameters

- Adjustment parameters

- Monitoring parameters

- Diagnosis parameters

- Maintenance parameters

3.1.1 Operating parameters

ABB TZIDC-110 Positioner V18346 Positioner

Signal range 0 ... 100%

Subranges are configurable, min. range 20 %

Recommended range > 50 %

Action (positioning signal)ABB V18346 Positioner

Increasing: Positioning signal 0 ... 100 % = direction 0 ... 100 %

Increasing: Positioning signal 0 ... 100 % = direction 100 ... 0 %

Characteristic curve (travel = f {signal})

Linear, equal percentage 1:25 or 1:50 or 25:1 or 50:1 or freely

configurable with 20 reference points.

Travel limit

ABB TZIDC-110 Positioner V18346 Positioner

The positioning travel, i.e. the stroke or angle of rotation, can be

reduced as required within the full range of 0 ... 100 %, provided that

a minimum value of 20 % is observed.

Shut-off function

This parameter can be set separately for each end position. When the

respective configured limit value is exceeded, the shut-off function

causes immediate travel of the actuator until reaching the set end

position.ABB V18346 Positioner

End Position Behavior

ABB TZIDC-110 Positioner V18346 Positioner

Selection option for behavior when moving into the end position.

Either the positioner additionally pressurizes the actuator and reaches

full actuating force in the end position, or it continues to control the

actuator in the end position and pressurizes the actuator only as much

as is required to maintain the position.

Travel time prolongation

This function can be used to increase the max. travel time for full travel. This time parameter can be set separately for each direction. ABB V18346 Positioner

Adjustment parameters

The TZIDC-110 positioner has a special function for automatic

adjustment of the parameters.

Additionally, the control parameters can be set manually to optimally

adapt them to the process requirements.

Tolerance band ABB V18346 Positioner

When reaching the tolerance band the position is considered as

corrected. From this point on, the position is further slowly re-adjusted

until the dead band is reached. The factory setting for this parameter

is 0.3 %.

Dead band (sensitivity)

ABB TZIDC-110 Positioner V18346 Positioner

When reaching the dead band, the position is held. The factory setting

for this parameter is 0.1 %.

Actuator spring action

Selection of the sensor shaft rotating sense (looking into the open

case), if the valve is moved to the safe position by the actuator spring

(actuator is depressurized via Y1/OUT1).

For double-acting actuators the actuator spring action corresponds to

pressurizing the pneumatic output (OUT2).

Display 0 … 100 %

Adjusting the display (0 ... 100%) according to the direction of action

for opening or closing the valve.
