4.1.7 PROGRAMABLE LEDS
The device has a number of programmable LEDs, which can be associated with PSL-generated signals. The
pr
ogrammable LEDs for most models are tri-colour and can be set to RED, YELLOW or GREEN. However the
programmable LEDs for some models are single-colour (red) only. The single-colour LEDs can be recognised by
virtue of the fact they are large and slightly oval, whereas the tri-colour LEDs are small and round.
