Setting instructions
The following points apply for devices with optional “self-test on starting”:
After applying the operating voltage the device starts a complete
function test. The green
LED3 flashes during the function test (see 18.3).
After the function test the relays switches - the switching contacts are closed thereafter.
10. Setting instructions
The unit has three measurement ranges, which can be selected by the switches S5 and S6.
For the device to operate properly,
both the switches
should not be in “
ON
” position, since
a non-specified measuring range would then be set.

11. Analog output
As the output value will be submitted constant current, by voting 0 to 20mA or 4 to 20mA.
The selection occurs by switching over of switch S4.
An output current of 20mA meets the 100%-value of the selected measurement range. In the
setting of 0 to 20mA is the valid relation 0.2mA per %, in the setting of 4 to 20mA is the valid
relation 4mA + (0.16mA per %).

12. Possible ground configurations
By using the jumper J1 and J2 the case potential,
cable shield and the internal signal ground could
be connected with each other by choice.
