•
Cables without connectors may be shortened.
•
The cover mounting screws should be slightly lubricated before fitting
(copper paste, graphite grease). Thus corrosion of the screws after
long periods of operation is prevented and easy unscrewing enabled.
3.1.5
Also to Be Noted
•
If the temperature sensor is disabled (e.g. if gasoline is delivered),
then a bridge must be set at the terminals for the temperature sensor
(PT100) instead, see drawings 321 and 330.
•
In sealed state the seal password (parameter 3.1.3), which enables
access to the electronic calibration seal, is no longer displayed.
The user who makes a change to the password must ensure that this
new password is appropriately documented. Same may, for example,
be saved in a closed envelope.
3.2 Terminal Box (only AI Version)
The certified terminals in the terminal box are not terminals in the usual
sense, but terminals with a pull-spring connection. The wires are not
screwed as with the previous version, but inserted from the top instead.
A screwdriver with a blade width of 2.5 mm (included in supplied items) is
needed to open the pull-springs.
The following working steps are necessary for the secure connection of
the wire ends (see Fig. 1):
Strip insulation from the wire end.
It is not necessary to use wire-end sleeves.
Press in the clamp in the terminal using the screwdriver.
•
Insert the wire-end into the open terminal.
•
Remove the screwdriver.
•
Check for firm seating in the terminal by pulling on the wire.
