Assembly, Disassembly
For terminal connection and exchange of sensor head you have to dismount the display.
This work may be carried out only when the device is voltage-free.
Disassembly
•
Open cover.
•
Push the white retaining bracket upwards (arrow 1, red) and lift the display board slightly.
•
Take the board left and right (arrow 2, blue) with two fingers (NOT BY THE FOIL) and pull it carefully
to the front.
•
Put the display board in a dry, clean and protected place.
Now you have access to the connector of the sensor head and can exchange it.
It is still necessary to dismount the cover and the mounting plate in order to connect the terminals.
•
Unscrew the mounting screw (arrow 4, blue).
•
Take cover plate by the retaining brackets, pull it a bit to the front and then push it to the top (arrow
3, red) until the plate leaves the two retaining slots.
•
Put the plate in a safe place.
Assembly
•
Hold cover plate to the front in a slight angle and insert the two brackets into the retaining slots
above the terminals of the board as far as it goes.
•
Push the board carefully inwards until it rests on the mounting bolt.
•
Secure it with the screw (arrow 1 blue).
•
Hold the display PCB horizontally above the transmitter circuit board, so that it fits with the hole in
the mandrel of the white retaining bracket and with the two slots in the guide brackets.
•
Press evenly and gently until the retaining bracket clicks into place.
