5.3 Configuring the rail-mount version
• Take a screwdriver and press the tip between the housing and the cover as shown in the
previous drawing.
• Remove the cover.
DANGER!
To avoid electric shocks and destructions or damages of the device, assure that all electrical
connections comply with the instructions within the chapter "Electrical connections".
DANGER!
Only perform the configuration described in this section if no sensor is connected to the
transmitter. Otherwise you could damage the cable insulation during soldering, furthermore the
cables could handicap during soldering.
INFORMATION!
In the standard delivery condition the transmitters are not preset. Therefore you have to make a
complete solder pad configuration before using the transmitter for the first time. Also note the
following items:
• The steps in this section show the complete configuration procedure in the correct order for
new transmitters. The manufacturer strongly recommends to follow this procedure,
otherwise the calibration may not be proper.
• As an option the manufacturer offers preset transmitters according to the customer's order.
Only in this case the solder pad configuration is not necessary. Though the manufacturer
strongly recommends to perform a calibration in this case.
• In some cases you have to change the solder pad configuration of a transmitter that has
already been in use. This may be the case e.g. if you must define a new zero point or
measuring span for a new application.
