FLOWBIRD CWT Compact Touch Manual page 25

When you push the coin return button, a small servo motor turns an actuation
arm which actuates a lever on top of the coin verifier. This lever opens the lid
slightly to release objects stuck inside.
Important:
The coin verifier can also be opened manually for inspection, emptying, and
cleaning.
The coin verifier is an industry standard 3.5" electronic device programmed to
recognize up to 16 coin types from optional currencies. For each coin type
recognized a unique code is sent to the CPU board.
Cale Access provides pre-programmed coin verifiers for all countries where the
terminals are sold, but clients can also program the modules themselves if
necessary. Contact Cale Access for further information about coin verifier
programming.
4.1.3.3 Escrow
The task of the escrow is to store the inserted coins until the customer accepts or
cancels the purchase. Accepted coins are guided into the coin box. Cancelling
the purchase empties the coins into the coin return cup. The volume of the
escrow is approximately 0.35 l, equal to about 120 coins.
