2. Earthen (Earth Ground)
To ensure that the Sabre Duo/Quattro Electronics operates perfectly, the following specifications
must be met:
•
The earth terminal (No.11) must be connected to the housing of the coffee machine by means of a
flexible lead
•
The flexible lead must have a large cross-section, minimum 1.5mm²
•
The flexible lead must be as short as possible and bolted to the housing by means of a serrated lock
washer
3. Keypads
The keypads (max. 2) of the Sabre Duo and (max 4) Quattro Electronics are connected to the control unit
by only one cable (loop). As a result each keypad has its own address, programmable by a jumper.
Therefore the keypads within the system must not be interchanged, i.e. keypad with designation "Group No.
1" always controls group No. 1.
4. Maintenance
The Sabre Duo/Quattro Electronics is basically maintenance-free for the end user.
5. Commissioning
The Sabre Duo/Quattro Electronics control unit must be connected according to our installation
specifications. After the coffee machine has been fully wired, connect the keypads to the control unit using
the ribbon cable enclosed. In the operating instructions the term "volume" is used for the portion keys. The
double function of the STOP key is designated "Stop/Continuous 5".
Volume 1
Volume 2
Volume 3 Volume 4 “Stop/Continuous 5” (Buttons)
6. Machine Specific Programming
6.1 Programming the Delay Time
The delay time between the time at which the level probe responds and the main valve of the boiler opens
can be set to the following values ranging from 2s to 20s: 2s, 5s, 10s, 15s, 20s.
Programming can only be performed on group 1.
The delay time is programmed as follows:
Insert the enclosed program plug (jumper) at position JP3 in accordance with the diagram for Duo on page
6 and Quattro page 7:
•
The LEDs for lines 1 to 4 then light up on the keyboard of group 1
•
If a delay time of 2s is desired, remove the program plug again to program the delay time.
