VALIDATOR HEAD UNIT REMOVAL
To remove the head unit from the
validator, first unlock the ‘Cashbox
& Head Release Lock’ (if fitted). Lift
the silver ‘Head Release Latch’
located on the front of the
validator, slide the head unit
forward and lift up away from the
chassis.
To replace the head unit, align the
lugs on the chassis with the groove
on the underside of the head
assembly and slide the head
assembly backwards until it clicks
securely into place

8.3 APPENDIX C – ESCROW FUNCTION
The NV200 has a single note escrow facility (pin 10) used in Parallel, Pulse and Binary
modes. This allows the Validator to hold onto the note once accepted, and then only
stack the note in the cash box when the host machine confirms that the Vend operation
has been completed. If no confirmation of the Vend is received then the note will be
returned to the customer after 30 seconds, (see Figure 10 – Escrow Timing Diagram).

- Escrow Timing Diagram
If the host machine itself aborts the transaction by setting the corresponding inhibit
input high, the note is returned immediately.
