3 Other operating modes of the G-18.mft - NRI

DESIGN G-18.mft with vending machine control system
Switching blocks (on coin validator)
On the rear of the device, the coin validator is
equipped with three switching blocks (S1–S3) 3
located below one another. The two upper switching
blocks S1 and S2 have eight DIL switches each,
and the lower block S3 has ten. (See Fig. 1a)
The 12 available coin channels or the coin types
assigned to the coin channels can be inhibited
individually using the first six DIL switches of
switching blocks S1 and S2 (see section "Inhibiting
coins" in Chap. 7 "Operation").
DIL switch 7 on the switching block S1 is used to determine whether the
customer will receive his goods if he has a credit that corresponds exactly
to the price or also if his credit is higher than the set price (see section "Set
exact price or overpay mode" in Chap. 6 "Starting up").
Using the eighth DIL switch of the upper switching block S1, you can disable
the operating button and operating switches of the additional control PCB
(see section "Disabling price and test switches/button" in Chap. 7 "Operation").
DIL switch 7 on the lower switching block S2 is used to set the coin validator
into teach mode in order to be able to configure new coins or tokens on site
without using any additional tools (see section "Teaching coin channels in
teach mode" in Chap. 7 "Operation").
The eighth DIL switch of the middle switching block S2 is used to define the
operating mode "vending machine control" (see Chap. 6 "Starting up").
The DIL switches 1–8 of the lower switching block S3 are not assigned in the
operating mode "vending machine control". Their switch position is not
relevant.
DIL switch 9 of the switching block S3 is used to set the MDB protocol and
DIL switch 10 is used to select which of the two memory blocks the coin
validator is to access (see Chap. 6 "Starting up" and section "Selecting
memory block" in Chap. 7 "Operation").
