To enter the settings mode, press the joystick for at least s when the
display is inactive.

NNoottee!! The last con iguration entered into the transmitter is always valid,
regardless o whether it was per ormed using the menu system or via
Modbus.
Viewing mode menu
Sub menu Description
P.# Pressure value
P.1 = sensor 1 / P.2 = sensor 2
F.# Flow value
F.1 = sensor 1 / F.2 = sensor 2
d.# UI: Value in digital mode
d.1 = UI1 / d.2 = UI2
u.# UI: Value in 0-10 V mode
u.1 = UI1 / u.2 = UI2
Sub menu Description
t.# UI: Value in temperature mode (°C)
t.1 = UI1 / t.2 = UI2
L.# UO: Value in digital mode
L.1 = UO1 / L.2 = UO2
U.# UO: Value in 0-10 V mode
U.1 = UO1 / U.2 = UO2
Two digits can be shown at a time in the display. Therefore, several
subsequent views are used to display a longer value. Example: A pressure
value of 23 0 Pa on sensor 1 is shown with three views, i.e. 1 P.1 2 23
3 0. The measuring unit for the displayed value is set via Modbus.
NNoottee!! The K- actor has to be set via Modbus to be able to view correct
low values. In ormation regarding low calculation is ound in the variable
list.

When the transmitter is connected to Regin’s Corrigo controller, it is
configured as an expansion unit. When configuring the unit for Regin's
freely programmable products the addressing can be set via Modbus. See
the Corrigo manual and the PDTX…-C variable list for more
information.

Three LEDs are available to show different states.
LEDs Description
Yellow RS485 data transmission indication
Red Global device status. Is activated when an error is
present (see the variable list for more details).
Green 1 Hz flash rate: Normal operation
5 Hz flash rate: Zero-set calibration is preformed
25 Hz flash rate: Factory reset is performed
Push-button
Action Description
Quick press Zero-set pressure calibration
The green LED will be flashing when the zero-set
operation has been made.
Long press (> 10 s) Reset to factory default settings
The green LEDs will be flashing during the opera-
tion. The unit will then reset and restart.
Zero-set pressure calibration
A short press on the push-button will zero-set calibrate the available
pressure sensors.
NNoottee!! Be sure to disconnect the pressure tubes be ore doing this. Let the
unit warm up or 10 minutes be ore attempting zero-set.
Factory reset
A long press on the push-button, more than 10 seconds, will perform a
factory restore of user defined settings. Table 4 displays some of the
settings that will be restored.
