"Battery empty" detection
The light-emitting diode on the left-hand side of the coin validator indicates
the voltage state of the battery when the return lever is pressed following the
insertion of a coin (see section "Displaying battery voltage" in Chap. 8
"Maintenance and service").
Inhibiting of specific coin types
If specific coin types are no longer to be accepted for payment at the vending
machine (e.g. because there are too many false coins of a specific coin type
in circulation), these coin types can be inhibited using the switching blocks
on the rear of the coin validator (see section "Inhibiting coins" in Chap. 7
"Operation").
Teach mode (optional)
The coin validator provides six memory locations (coin channels) for
configuring a maximum number of six new coins/tokens, which means that
coin/token measured values can be re-assigned directly on the vending
machine by inserting the respective coins/tokens. The acceptance band
generated then accepts these tokens as payment in the vending machine.
(See section "Teaching coin channels in teach mode" in Chap. 7 "Operation")
Communication with MDB periphery (optional)
If the coin validator is supposed to control external devices using the MDB
protocol, an NRI card reader and NRI display can be connected using the
10-pole MDB interface on the rear of the device and using an MDB cable set
(see section "Accessories" in Chap. 10 "Technical data").
