Hardware Controls; Troubleshooting - Philips Dynalite DBC1205 Installation Manual

Connecting Serial Control Cables
AUX Input - This is a dry contact interface that is active low. The dry contact is connected between the
AUX and GND terminals on the DyNet connector strip. The function of the AUX input is programmable.
Ensure that the cable length between the dry contact and terminal strip is no longer than 2 metres.
Service LED - The Service LED has 3 signalling modes, which are useful for troubleshooting:
Blinking slowly (1Hz) = Normal Operation
Blinking fast (4Hz) = Network Activity Detected
On = Fault
Service Switch - The Service Switch has three functions:
1 push = Transmit Network ID
3 pushes = All Channels 100%
Push & hold for 4 sec = Reboot
Top Set - This adjusts the maximum output that all other control sources can select, ie: if the Top Set is
fully clockwise, 100% selected by a control source will give 100% output. If it is fully anti-clockwise,
100% selected by a control source will give 50% output. This control is useful for extending lamp life
and can be operated without any form of network control, effectively turning the device into a stand-
alone power conditioner and lamp protector.
Accessory Module Socket - Accepts plug in modules for optional features such as DMX512 ports and
Time clocks. Consult your distributor for details on the available accessory modules.
