Pay attention to the following:
• The device is approved for protection class II and is generally operated without a protective
earth connection.
• To guarantee measuring stability and functional safety, you have to ground the outer
screen of the sensor cable:
– Inductive sensors: terminal "S"
– Conductive sensors: PE distributor rail
This is on the cover frame for panel-mounted instruments and in the connection
compartment for field devices. Ground the PE distributor rail or the ground terminal.
• The circuits "E" and "H" are not galvanically isolated from each other.

5.1.3 Key assignment
CAL key
When you press the CAL key, the device first prompts you for the
calibration access code:
• Code 22 for calibration
• Code 0 or any other code for reading the last calibration data
Use the CAL key to accept the calibration data or to switch from field
to field within the calibration menu.
ENTER key
When you press the ENTER key, the device first prompts you for the
setup mode access code:
• Code 22 for setup and configuration
• Code 0 or any other code for reading all configuration data.
The ENTER key has several functions:
• Calls up the Setup menu from the measuring mode.
• Saves (confirms) data entered in the setup mode.
• Moves on within function groups.
PLUS key and MINUS key
In the setup mode, the PLUS and MINUS keys have the following
functions:
• Selection of function groups.
Press the MINUS key to select the function groups in the order
given in the "System configuration" section.
• Configuration of parameters and numerical values
• Operation of the relay in manual mode
In the measuring mode, you get the following sequence of functions
by repeatedly pressing the PLUS key:
1. Temperature display in F
2. Temperature display hidden
3. Display of the uncompensated conductivity
4. Return to basic settings
In the measuring mode, the following is displayed in sequence by
repeatedly pressing the MINUS key:
1. Current errors are displayed in rotation (max. 10).
2. Once all the errors have been displayed, the standard
measurement display appears. In the function group F, an alarm
can be defined separately for each error code.
REL key
In the manual mode, you can use the REL key to switch between the
relay and the manual start of cleaning.
In the automatic mode, you can use the REL key to read out the
switch-on points assigned to the relay in question.
Press the PLUS key to jump to the settings of the next relay. Use the
REL key to get back to the display mode (automatic return after 30 s).
