Bench Configuration (Optional)
3.1 Introduction
About This Section
The bench configuration is an optional procedure for checking your device. This section provides a
procedure for configuring the Logix 3400IQ digital positioner. This allows the user to load configura-
tion information into the device before it is connected in a fieldbus network. This enables the user to
perform a bench check and configuration of the device before installation. Calibration is also possible
before the device is installed in the field.
Device Calibration
A stroke calibration should be performed upon installation of the valve. The actuator pressure
calibration should be verified on advanced models (Logix 3400IQ digital positioner). Instructions for
performing this calibration can be found in Section 10.
3.2 Bench Check
Configure Logix 3400IQ Digital Positioner Before Installation
Using the NI-FBUS Configurator (or other fieldbus device configuration application), the user can
perform an bench check of the Logix 3400IQ digital positioner before it is mounted and connected
to the process hardware and the fieldbus network. By wiring the device to the fieldbus interface of
a PC and using a fieldbus power supply to furnish power to the device, the user can read and write
parameters in the Logix 3400IQ digital positioner.
1. Connect fieldbus cable to junction block fieldbus interface card to the fieldbus network.
CAUTION: Observe polarity of fieldbus cable throughout the network.
2. Loosen end-cap lock and remove end-cap cover from terminal block end of positioner housing.
3. The Logix 3400IQ is not polarity sensitive. Connect either wire to either terminal screw.
