8 TZIDC, TZIDC-200 DIGITAL POSITIONER | COI/TZIDC/TZIDC-200-EN REV. B
… 2 Operation
… Operating modes
In both control modes 1.0 and 1.1, several values can be
displayed besides the current actuator position:
Setpoint display
1. Press and hold the button.
The setpoint is displayed.
2. Briefly press ENTER.
The setpoint display is toggled between the setpoint current at
the input terminals in mA and the setpoint as a percentage of
the stroke range.
Temperature display
1. Press and hold the button.
The temperature inside the case is displayed.
2. Briefly press ENTER.
3. The temperature display is toggled between °C and °F.
Display of control deviation
1. Press and hold the and button.
The control deviation is displayed as a percentage (%) of the
stroke range.
Operating mode 1.2: Manual adjustment in the stroke
range
The valve is adjusted manually using the direction buttons and
within the stroke range.
1. Press and hold the button for the desired direction.
2. To activate the high speed mode in the manual mode, press
the second arrow button.
If air escapes due to a leakage, the position will not be
readjusted.
Configured stroke limit positions and stroke times are not
effective in manual mode.
In this operating mode the valve position is indicated as a
percentage (%) of the stroke range.
Operating mode 1.3: Manual adjustment in the sensor
range
See operating mode 1.2
Unlike step 1.2, this operating mode is used to determine
whether the available detection range of the position sensor is
used correctly after mounting the positioner to the actuator.
Therefore, the valve position is given here in angular degrees in
reference to the sensor range (i.e. 0 to 140 °).
