TABLE OF CONTENTS 

 

 

1. OUTLINE 

The NBM-3000 Series Bill Validator has been developed based upon the M.D.B. communication specifications. This validator is equipped with many added features, such as all plastic construction, built-in antisalting system, accepts U.S. $1, $5 and coupons, vertical sensing, flash Rom programming, unique bill stacking method and other exclusive features. 

 

2. GENERAL SPECIFICATIONS Specifications and design are subject to change without notice. 

 

 

* Detailed Specifications

When the authentic bill (US $1, $5 or Coupon) is inserted into the validator and is found to be genuine, this information is sent to the main controller. 

 

(2) Identified as a Counterfeit Bill 

The inserted counterfeit bill is automatically returned. 

* Bills 146mm or shorter and 166mm or longer. 

* Bills having an unclear optical pattern. 

(3) Inserted Bill Not Accepted 

The bill validator is unable to accept bills in the following cases: 

* When the stacker is determined to be full. 

* When the validator develops a motor fault. 

* When the validator develops a sensor fault. (Dirty) 

* If a bill jam operation. 

* When the bill is pulled from the validator during operation. 

(4) When the Stacker is Full 

The full signal is sent to the main controller when the stacker is full. To clear this signal; open the stacker, remove the bills and close (safety switch ON/OFF) the stacker. This is transmitted to the main controller.
