If the motor of the NRI G-46 MDB tube continuously spins as if the coin reset button is stuck, check for a blocked payout slide or jammed coin and remove any obstruction. Then, carry out a test using the internal keyboard. Also, ensure the flat cable between the payout slide and power supply unit is properly connected and not defective. If the sensor for the final motor position or motor control is faulty, replace the payout set.

G-46 G-46 MDB ESIGN AND FUNCTION OF THE Sorting the coins A coin inserted into the machine first enters the electronic coin validator, where coin characteristics such as alloy, diameter, weight and embossing are checked by means of probes and light barriers. If the measured values do not lie within the programmed limit values the recognized false coin will be rejected via the coin return.
G-46 MDB G-46 ESIGN AND FUNCTION OF THE Programmed coin channels The coin validator has 16 „memory locations“ for coin acceptance which can be assigned up to 16 different coin types or tokens. These „memory locations“ are called coin channels. The acceptance band of a coin type/ token is allocated to a coin channel and the coin type/token is accepted in that channel.
G-46 G-46 MDB ESIGN AND FUNCTION OF THE Inhibiting coin channels with DIL switches The 16 coin channels can be inhibited by means of the setting module (Pro 15, see chap. 8). In addition, it is possible to inhibit the channels 1–8 by means of DIL switches, which are situated on the rear of the coin validator.
