INTRODUCTION

IPAQ-H is a universal and intelligent 2-wire In-head transmitter for
temperature and other measurement applications.
IPAQ-HX 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 3.05 or later. The latest version of
IPRO can be downloaded from http://www.inor.com. When the trans-
mitter is set from a PC no calibration is needed.
!
The transmitter must not be connected to a computer,
when the transmitter is in hazardous area.
The transmitter is polarity protected and will not be damaged by
connecting the power supply with the wrong polarity, but the output
will be 0 mA.
The maximum load in the output loop depends on the supply voltage,
see "DATA shortform"
The transmitter continuosly supervises the isolation resistance in
thermocouples and 3-wire-connected Pt100 including the connection
wires. If the isolation resistance is low it causes error in the
measurements and consequently a faulty ouptput. The transmitter
indicates low isolation resistance by forcing the output to a preprogram-
med value. This function requires setting by the PC-program IPRO and
the use of a temperature sensor with an extra wire.
Sensor wire check: the transmitter uses a pulsating technique to moni-
tor 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-H/HX 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 (follow the instructions in
"IPRO User instructions").
For keeping the safety of the internal circuits in the
!
IPAQ-HX, always use Ex-power supply or a zener barrier
with limitations according to Ex-data and IPRO-X con-
figuration cable when making a configuration with the trans-
mitter in or connected to hazardous area.
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.
