Electrical description
All the signals
handled by the hopper are
in negative logic
: each signal is considered active when it
is LOW (GND).
3.1 CINCH connector Pin-Out
This connector can be found on the right side (
standard)
or left side
(reverse)
of the hopper
.
The functions of the pins will be described in the next paragraphs.
3.2 Power Supply
This equipment must be supplied with 24V direct voltage.
The 24V
version requires
+24Vdc
to
pin10
for the operation of the logic card and
+24Vdc
to
pin 9
for the operation of the motor.
The speed of coins dispensing is proportional to the voltage supplied to the motor. We recommend
to keep it between 18Vdc and 27Vdc.
A voltage of 24 Vdc produces 240 pcs. output per minute.
When the hopper level controls are made through optic sensors, do connect the electrode plates to the
machine ground terminals.

*The motor overload current draw shall always be limited by the electronic circuit. The 1 A draw, corresponding to
hold-up of the motor, will therefore be reached only for a few msec.
