QCC-PLT 300 - REV001A
Wiring, terminals and cables
Considering the high currents involved, a few precautions on wiring
are in order:
• the cables used for the power stage should be no longer than 20 m.
• Use cables having an adequate cross-section (max. terminal size
2.5 mm
2
), both for connecting the power supply and wiring the
devices.
• The maximum length of the wires used for the control signal BUS
is 300 metres. Beyond 200 metres a specific terminal is needed.
QCC-PLT 300
OPERATION
The QCC-PLT 300 receives an input command signal (DMX512) which is turned into a control signal on two wires
intended to power and control the QCC-DRV CH4 (which, in turn, will be connected to the RGBW LED light sources). This
characteristic is therefore used to reduce the number of wires on the system.
The QCC-PLT 300 can receive a command signal from DMX512 devices or from push-buttons:
A) DMX512
Standard protocol used in many control devices (touch panels and other user interfaces). Up to 32 QCC-DRV CH4 units
can be managed and, therefore, 32 different light environments.
For the command section, there are two possibilities:
• command from a single point: the control device is directly connected to the QCC-PLT 300 via the DMX512 port.
• command from several points: in this case, it is necessary to add a QCC-SPT DMX, which is a device that can
manage the DMX512 signal coming from different control devices.
B) PUSH-BUTTONS
By means of four inputs controlled by dry contact push-buttons, the RGBW system can be managed as follows:
• input 1 push-button:
- Briefly press the push-button at input 1 to turn on the light at the last brightness and colour value being set.
- Briefly press the push-button at input 1 to turn off the light.
- Press and hold the push-button at input 1 (>2 sec) to vary the brightness continuously from increasing to decreasing
and vice versa, of the selected colour.
- Once the desired brightness is reached, release the push-button at input 1 to save the value.
• input 2 push-button:
- Briefly press the push-button at input 2 to vary the colour at steps, choosing among: red, green, blue, yellow, violet,
sky blue and white.
• input 3 push-button:
- Briefly press the push-button at input 3 to enable a mixing colour change scenario.
- When the scenario is in operation, briefly press the push-button at input 3 to adjust the speed in 3 colour change time
modes: 10, 5 and 2 seconds.
- To exit the scenario mode, just briefly press any push-button except for the one at input 3.
• input 4 push-button:
- Briefly press the push-button at input 4 to enable only the White channel at the maximum
- Briefly press the push-button at input 4 to turn off the White channel
- Press and hold the push-button at input 4 (>2 sec) to vary the brightness continuously from increasing to decreasing
and vice versa.
DO NOT UNDER ANY CIRCUMSTANCES CONNECT THE LEDS DIRECTLY
TO THE TERMINALS OF THE POWER SUPPLY.
