8.0 ADDITIONAL INFORMATION
8.1 LED FUNCTIONS & ARRANGEMENTS
As described in Section 3, the system control is completely digital. System control software is comprised of measurements,
evaluation of measurements, threshold control, and a programmable logic control (PLC) known as the User Program. The
individual parts are fully integrated to operate together as a software control system. The most important function is that of the
User Program. The PLC has digital inputs and outputs which converts the information coming from the hardware into a form
recognizable by the User Program software. Each input and output is monitored by an LED, and all inputs and outputs, which
are used, are shown on the cont
rol diagrams. Checking the status of these LED’s is a quick and easy way of establishing the
operational status of the converter, and is useful during fault-finding. An illuminated LED indicates a high potential (+24V) at
the hardware digital input or output. If the LED is off, then the potential is low (0V).
