1 Safety instructions
•Read instruction manual carefully before operating the device! Keep for later
reference.
•Mounting and installation must be carried out by suitably qualified and competent
persons only.
•When working on the device hazardous voltages must not be connected to
the device! The terminals J1-J12 are not isolated from the measuring
circuit
•The device must not be used as the only protective device or protective
shutdown
•The device is not intended to protect persons or facilities against harm. Specific
devices must be used to guarantee safety (protection relays, cut-off switches,
etc.).
•When connecting switches to the terminals J1-J6, only switches must be used
whose isolation voltage is at least twice the maximum occurring measurement
voltage. For example, when measuring 30;V C switches must be isolated for at
least 60;V.
•o not open the housing!
•o not use the device in the presence of explosive or flammable substances!
•All cables carrying hazardous voltages must be secured with external separators.

3 Intended use
•Measurement of current in the specified measuring range for process signals
•Indoor use non condensing, non corrosive.
•Panel mounting.
•In operation, supply the device preferably via screw terminals with 12 to 24;V
AC/ C. If the device is supplied via USB in operation, USB supply voltage must
be at least 5;V.
•Failure to comply with these instructions will void all guarantee and warranty.
4 Description
The measurement mode analogue signal 0/4 to 20 mA C is supported at two
measurement inputs. The multi display with RGB backlight is able to display up to
four parameters simultaneously. Thresholds can be associated with individual
warning colours. The unit can be switched between measurement modes via an
external switch. Minimum and maximum values are recorded and can be displayed
and reset via jumper or an external switch. Measured values are recorded over a
timespan of 36 seconds up to 14 days. The timebase as well as the display of the
measuring history can be activated by an external switch. The measured values
remain stored as long as the device is supplied with voltage.
The following parameters can be adjusted using the configuration software “ igalox
Manager”: scale endpoint, scale caption, display style (pointer, tachometer, bar
graph, and more), splash image, backlight colour, thresholds for alarm output,
threshold warning colour (light, blink), hysteresis, and more. Recorded
measurement values can be read and a continuous transmission of the actual
measuring value can be enabled. Using the software, values can be viewed and
exported as CSV. epending on the model, measured values can be transmitted via
USB, XBEE radio technology or RS485 Modbus interface. In addition, the devices
feature a counting function with data retention. This enables operating-hours-
counters or time-counters for exceeding and falling below threshold values.

6 Mounting
Carefully insert the device into the panel
cut-out. Insert the mounting bracket from
the back and push towards the panel until
the device sits tight. Make sure the
mounting bracket is snapped into the side
of the housing. To ensure IP65 protection
(dust and water jet) when mounting in a
front panel, use optional gasket
(separately available).

8 Configuration
Connect the device to a computer:
USB: Connect the device and the computer using a USB cable. The
device driver is installed automatically if the computer is connected to
the Internet.
XBEE: Insert the XBEE stick into the computer. The device driver is
installed automatically if the computer is connected to the Internet. In
order to reset the XBEE settings, short-circuit terminal J8.
RS485: Short-circuit terminal J8. isconnect the device from the
Modbus network and connect it to the computer using an RS485 USB
adapter. After completing the configuration, open J8 again.
Start the " igalox Manager" software and connect it to the device. Settings can
then be made on the various tabs and saved in the device.
Please note that the measurement mode selected in “ igalox Manager” is displayed
only until the power supply of the PM72 is interrupted.
In further operation, the device always shows the first
measurement mode or the one that is selected by the jumpers
J4-J6 (see table “Measurement mode”),
in case of a multi display style additionally the following measuring modes

9 Other settings
The following functions can be activated independently during operation by short-
circuiting connectors J1-J3, e.g. using a jumper or switch:
J1: Graphical historic data display
The unit displays the stored values within
the set time base as a graphical trend. The
time base can be set to days (7, 14),
hours (1, 3, 6, 12, 24, 48, 72), minutes (3,
15, 30) or seconds (36).
The time base can be changed by
alternately opening and closing J1 (interval
< 2 sec). When first opening and closing J1
the current time base is displayed. For each
subsequent opening and closing the time
base changes to the next setting. In order to
save the setting permanently, the software
“ igalox Manager” has to be used.
J2: Min-Max display
The display shows the maximum and
minimum values recorded since the last
reset. The values can be reset by opening
and closing connection J2 shortly (interval <
2 sec). The display shows “Minmax reset”.
J3: Auto-scaling
The device automatically changes the upper
scale caption depending on the current
measuring value between 10, 100 and the
set upper scale caption.

10 Maintenance
Periodically check all external cable connections.
11 Cleaning
Observe the safety instructions before cleaning the device. Clean the device with a
dry lint-free soft cloth. o not use solvents.
