INTERFACE connection - chap.13<br />
Technical manual<br />
13.9 INTERFACE CONNECTION diagram<br />
Functional Technical Specification 32 I/O relay<br />
Thanks to the interface dosing can be connected to management systems that use for each key the corresponding<br />
output of a relay or of an open-collector transistor.<br />
The I/O card utilises a relay contact.<br />
All relays share the same connection on pins 37-38-39-40 of the output connector CN7.<br />
On this latter, besides the counting outputs, there is the enabling for selections.<br />
The “waiter key” must short circuit the signal of pin 33 with the ground of pin 35.<br />
The signals on the relays have a duration of 500 mSec.<br />
Installation procedure<br />
1) Connect the I/O card to the dosage with the dedicated serial transmission cable and the 12V power supply<br />
cable, following the enclosed diagram.<br />
2) Programme the coffee doses, inserting the programming key according to the known procedures.<br />
3) Take the programming key out and verify that selections are locked without the waiter’s key inserted<br />
between pin 33 and pin 35.<br />
The lever switch on the I/O must always be left in the I/O active position<br />
Output correspondence<br />
Key corresponds to the output of a relay.<br />
To better identify them, summarising tables follow giving the connector output with the corresponding selection<br />
push button.<br />
