6. Electrical connection
Advice:
The galvanic insulation in devices with temperature sensors, that do not have a
galvanic connection to an extrinsic potential, can be cancelled by a bridge from
terminal 2 to 4 and thus stabilise the device against external failures.
Devices with a supply of 230 VAC need to connect terminal 3 to signal ground.

7. Function and operation description
Operation
The operation is divided into two different levels.
Menu Level
Here it is possible to navigate between the individual menu items.
Parameterization Level
The parameters stored in the menu item can be parameterized here.
Functions that can be adjusted or changed are always indicated with a flashing
of the display. Adjustments made at the parameterization level should be always
confirmed by pressing the [P] key to save them. However, the display
automatically saves all adjustments and then switches to operation mode if no
further keys are pressed within 10 seconds.

8. Setting up the device
8.1 Switching on
Once the installation is complete, you can start the device by applying the current
loop. Check beforehand once again that all the electrical connections are correct.
Starting sequence
For 1 second during the switch-on progress, the segment test (8 8 8 8) is displayed,
followed by an indication of the software type and, after that, also for 1 second, the
software version. After the start-up sequence, the device switches to
operation/display mode.
8.2 Standard parameterization
To be able to parameterize the display, press the [P] key in operating mode for 1
second. The display then changes to the meu level with the first menu item TYPE.

the display switches to the extended parameterization mode. Operation is the
same as in standard parameterization.
