1 Safety instructions
Safe operation of the panel meter is only guaranteed if these Operating Instructions have
been read and the safety instructions have been observed.
1.1 Designated use
The panel meter analyzes analog process variables and depicts them on its multicolored
display. Processes can be monitored and controlled using analog and digital outputs and
limit relays. The device provides the user with a wide range of software functions for this
purpose.
Power can be supplied to 2-wire sensors with the integrated transmitter power supply.
– The device is seen as an associated electrical apparatus and may not be installed in
hazardous areas.
– The manufacturer does not accept liability for damage caused by improper or non-
designated use. The device may not be converted or modified in any way.
– The device is designed for installation in a panel and may only be operated in an installed
state.
1.2 Installation, commissioning and operation
This device has been constructed to state-of-the-art technology and meets all applicable
standards and EU directives. The device, however, can be a source of application-related
danger if used improperly or other than intended.
Installation, wiring, commissioning and maintenance of the device must only be carried out
by trained technical personnel. They must have read and understood these Operating
Instructions and must follow the instructions they contain. The information in the electrical
wiring diagrams (see Section 4 'Wiring') must be observed closely.
1.3 Operational safety
Technical improvement
The manufacturer reserves the right to adapt technical details to the most up-to-date
technical developments without any special announcement. Contact your local sales center
for information about the current state of and possible extensions to the Operating
Instructions.
1.4 Return
For a return, e.g. in case of repair, the device must be sent in protective packaging. The
original packaging offers the best protection. Repairs must only be carried out by your
supplier's service organization.
Please enclose a note describing the fault and the application when sending the unit
in for repair.

5.3.3 Disabling the programming mode
User code
The configuration can be protected against unintentional access by means of a four-digit
code. This code is defined in menu item 55 "Parameter/user code". All the parameters remain
visible but can only be changed after entering the user code.The "key" symbol is shown on the
display. If the limit values are also to be locked, the "Limit code" must be set to "On" in menu
item 55. Limit values can then only be changed after entering the user code. If the limit code
is set to "Off", limit values can be changed without entering the user code. All the other
parameters are locked, however.
Hardware locking
In addition, configuration can also be locked using a connector on the rear of the device (see
drawing). This is indicated by the "padlock" symbol on the display.
To hardware-lock the measuring device, insert the jumper into position J1 in the top right-
hand corner on the rear of the device.

6 Commissioning
6.1 Function check
Make sure that all post-connection checks have been carried out before you commission
your device:
• Checklist Section 4.3 'Post-connection check'
6.2 Switching on the measuring device
Once the operating voltage is applied, the green LED indicates that the instrument is
operational.
• When the unit is delivered, the device parameters are used as per the factory settings.
• When commissioning a device already configured or preset, measuring is immediately
started as per the settings. The limit values only switch once the first measured value has
been determined.
• The limit values are only activated as per their configuration once a valid measured value
is present.
6.3 Device configuration
This section describes all the configurable instrument parameters with the associated value
ranges and factory settings (default values, marked in bold).
6.3.1 Analog input - INPUT/M1
All the parameters that can be selected for the input can be found under the analog input
menu item which is marked as INPUT in the device.
Remove the protective strip from the display as this restricts display legibility
otherwise.
