2 SERIAL COMPACT HOPPER
2.1 Introduction
The Serial Compact Hopper Mk2 or SCH2 is a serially controlled Compact Hopper
manufactured by Money Controls. The serial interface is
ccTalk , firmly established as a leading,
low-speed device control protocol in the money-transaction industry. A key feature of ccTalk is
its optimal balance between simplicity and security.
2.2 Safety Note

following requirements:-

The equipment must be protected by a 3A fuse.

The equipment must be supplied from a SELV limited power source.

The equipment must be installed in an enclosure but positioned so that it is
external to any fire enclosure area within the main enclosure.
2.2.1 INSTALLATION AND REMOVAL
Warning: Ensure that the power has been disconnected from the Hopper before
removal or servicing.
2.2.2 HAZARDOUS MOVING PARTS
Warning: There are hazardous moving parts, keep fingers and other body parts away.
Consideration to this hazard must be assessed in the end use application.
2.2.3 HEALTH AND SAFETY
Warning: Due to the potential respiratory hazards, it is highly recommended that a
facemask be worn to prevent the inhalation of dust particles dislodged during the
maintenance or cleaning process or the clearing of jammed coins.
2.3 Mechanical Description
Each disc contains a number of holes in which the coins are held. The disc is driven via a gear
train, by the motor. As the disc rotates, the coin at the bottom of one of the stacks will make
contact with the ejector fingers. The fingers will move back and, at the same time, the coin will
start to move outwards to the exit slot.
Once the coin reaches the exit slot, the spring loaded ejector fingers will be able to return to
their original position and, in doing so, will push the coin out of the hopper.
An optical coin detector is created by infrared transmitters and photo detectors situated on the
PCB. The infrared light beam is routed across the exit slot via a light guide. When a coin passes
through the exit, the light beam will be broken and a coin output signal will be generated.
There are a range of discs, ejector fingers and adjuster plates available to provide optimum
performance for coins within the specified range.
