3.4.3 Power Supply Guidance

Check the power requirements of the host machine and other peripherals to
dimension a suitable power environment for the machine setup.
The unit shall be supplied from a source specified as Electrical Energy Source Class 1
(ES1) to IEC/UL 62368-1, or specified as SELV according to IEC/UL 60950-1
TDK Lambda manufactures suitable power supplies. See table below for further
details.

3.5.1 Opto-Isolated Inputs

The NV200 Spectral natively supports Opto-isolated communication, the connection
requires a reciprocal circuit to be established on the host side. The pin outs for the
opto-isolated inputs can be found in

3.6 Reliability Data

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
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.
