1. Brief description
The panel meter instrument IM3-7C is a 5-digit device for Pt100 temperature sensors and a visual
threshold value monitoring via the display. The configuration happens via three keys at the front or by the
optional PC software PM-TOOL. The integrated programming interlock prevents unrequested changes of
parameters and can be unlocked again with an individual code. Optional an analog output for further
processing in the equipment is available. And on demand two free adjustable setpoints with which
threshold values can be controlled and reported to an superior master display.
The electrical connection is done via plug-in terminals on the back side.
Selectable functions like e.g. the recall of the min/max-value, a direct threshold value regulation during
operation mode, complete the modern device concept.

4. Function and operation description
Operation
The operation is divided into three different levels.
Menu level (delivery status)
The menu level is for the standard settings of the device. Only menu items which are sufficient to set the
device into operation are displayed. To get into the professional level, run through the menu level and
parameterise ““ under menu item .
Menu group level (complete function volume)
Suited for complex applications as e.g. linkage of alarms, setpoint treatment, totaliser function etc. In this level
function groups which allow an extended parameterisation of the standard settings are availabe. To leave the
menu group level, run through this level and parameterise „ „ under menu item .
Parameterisation level:
Parameter deposited in the menu item can here be parameterised. Functions, that can be changed or
adjusted, are always signalised by a flashing of the display. Settings that are made in the parameterisation
level are confirmed with [P] and thus safed. Pressing the [O]-key („zero-key“) leads to a break-off of the value
input and to a change into the menu level. All adjustments are saved automatically by the device and it
changes into operating mode, if no further key operation is done within the next 10 seconds.

4. Function and operation description
4.1 Parameterisation software PM-TOOL:
Included in the delivery of the PM-TOOL are the software on CD and an USB-cable with device
adapter. The connection happens via a 4-pole micromatch-plug on the back side of the device, to
the PC-side the connection happens via an USB plug.
System requirements: PC incl. USB interface
Software: Windows XP, Windows VISTA
With this tool the device configuration can be generated, omitted and safed on the PC. The
parameters can be changed via the easy to handle program surface, whereat the operating mode
and the possible selection options can be preset by the program.

5. Setting up the device
5.1. Switching on
Once the installation is complete, start the device by applying the voltage supply. Before, check once again
that all electrical connections are correct.
Starting sequence
For 1 second during the switching-on process, the segment test ( ) is displayed followed by an
indication of the software type and, after that, also for 1 second the software version. After the starting
sequence, the device switches to operation/display mode.
5.2. Standard parameterisation: (Flat operation level)
To parameterize the display, press the [P]-key in operating mode for 1 second. The display then changes to
the menu level with the first menu item .
5. Setting up the device
Menu level Parameterisation level
Type of temperature metering,
Default:
The temperature can be displayed in °C or in °F. Confirm the selection with [P] and the display
switches back to menu level.
Setting the decimal point, :
Default:
The decimal point on the display and the physical unit can be changed with [▲] [▼]. If e.g.
temperature measurement in °C is selected, then choose between 0°C and 0.0°C in the
parameterisation level. Confirm with [P], the display then switches back to the menu level
again.
Setting the measuring range start / offset value, :
Default:
The value for the sensor calibration is selectable from the smallest to the highest digit with
[▲][▼] and confirmed with [P]. After the last digit the display switches back to the menu level
again. The value calibration for a temperature measurement in °C can be adjusted between -
20.0 and +20.0 and in °F between -36.0 and +36.0. If the type of the measurement is changed
later, then the value is rounded.
Setting the display time, :
Default:
The display time is set with [▲] [▼]. The display moves up in increments of 0.1 up to 1 second
and in increments of 1.0 to 10.0 seconds. Confirm the selection by pressing the [P] button. The
display then switches back to the menu level again.

exceedance with (for HIGH = higher limit value). If e.g. limit value 1 is on a threshold level
of 100 and allocated with function , an alarm is activated by reaching the threshold level. If
the threshold value was allocated to an alarm will be activated by undercutting the
threshold value, as long as the hysteresis is zero.
