INTRODUCTION
IPAQ-L is a universal and intelligent 2-wire rail-mounted transmitter
for temperature and other measurement applications.
IPAQ-LX is the Intrinsic Safe version for use in Ex-applications.
G E N E R A L I N F O R M A T I O N
The transmitter is configured from a standard IBM compatible PC by
using the IPRO software version 3.07 or later. The latest version of
IPRO can be downloaded from http://www.inor.com. When the
transmitter is set from a PC no calibration is needed.
!
When calibrate/configure "online" with the input
connected to hazardous area the ATEX certified version of
IPRO-X cable must be used.
The transmitter is polarity protected and will not be damaged by
connecting the power supply with the wrong polarity, but the out-
put will be 0 mA.
The maximum load in the output loop depends on the supply
voltage,see "DATA shortform"
"Isolation input/output/PC" mentioned in the data sheet,
indicates signal isolation only. It shall not be interpreted as
an IS galvanic isolation like an isolating barrier. Therefore
ordinary care in selecting barrier and grounding should be
considered for the IPAQ-LX.
Sensor wire check: the transmitter uses a pulsating technique to
monitor sensor break or sensor shortened to avoid measuring errors.
This pulsating signal may interfere with some electronic calibrators.
By selecting "Sensor Break = None" in the IPRO software and
download the configuration into the transmitter the pulsating signal
is turned off.

CONFIGURATION
The IPAQ-L/LX transmitter must be powered, when you configure
the transmitter, (see "Connections" fig.1). If IPRO (the IPAQ software)
isn't installed in your PC, install the software.
For keeping the safety of the internal circuits in the
IPAQ-LX, always use Ex-power supply or a zener barrier with
limitations according to Ex-data and IPRO-X configuration
cable when making a configuration.
When choosing differential temperature measuments with Pt100 be
sure to select "sensor break" = none.
Configuration from PC is "on-line", that is, the transmitter can be
configured while in operation if the area is known to be non-hazardous.
The output is frozen while transmission from PC to IPAQ take place.
When transfer is done the transmitter uses the new parameters.
