3.6 Reliability Data

3.6.1 MCBI/MCBF

Below is an explanation outlining the Mean Cycles Between Failure (MCBF) & Mean
Cycles Between Interruption (MCBI) for the NV200 Spectral. Where a cycle is defined
as a note/ticket either stacked, stored or paid-out. An example is if £20 is accepted and
a £10 paid out that would be classed as 2 cycles.
The difference between MCBF and MCBI is that a failure is classed as an event which
will require a service call – e.g. unit is seeing poor acceptance. Whereas an interruption
is an event which store/site staff could rectify without a trained engineer present – e.g.
clearing a note path jam.
As shown in Section 2.4 the NV200 Spectral is a modular solution and these modules
increase the complexity of the system. As such, each time one of these additional
modules are attached the current MCBF and MCBI is halved. The MCBF for the NV200
Spectral is 200,000 cycles.

3.6.2 Duty Cycle

When using the Safe Interface module, there is a maximum duty cycle. If this is
exceeded, the operation of the unit will change. The number of notes inserted into the
unit is counted for the previous 45 minutes:
Notes Counted Delay Added Between Note Inserts
0 – 250 0 seconds
400 1 second
500+ 1.5 Seconds
Between 250 notes and 400 notes the delay will gradually increase from 0 to 1s
Between 400 notes and 500 notes the delay will gradually increase from 1s to 1.5s
The number of notes inserted is also counted for the previous 5 minutes, the times
above are adjusted accordingly:
Notes Counted Delay Added Between Note Inserts
50+ 1 x above delay
25 - 50 0.5 x above delay
0 Zero delay
