C-BUS TRAINING MANUAL - VOL 2

1.1 Fault Finding Notes

Note *1

Checking the Pink cat 5 between C-Bus positive (Blue and Orange) and Negative (Blue/white and

Orange/white). Use a multimeter start on the DC voltage range to conrm there is no voltage . Then

change to the ohms range, and break the circuit down in to segments until the short can be identiﬁed.

If the Unit LED is ashing, check for short circuit between C-Bus negative and Brown/Brown-White

and C-Bus negative and Green/Green-White.

Note *2

Power supply units check that there are sufﬁcient Power supplies to power the system.

Din rail output unit with power provide 200 mA

Din rail stand alone PSU provides 350 mA

Pro series dimmers provide 60 mA

Typical current demands are:

• PCI =32 mA

• PIR’s =18 mA

• Neo type Key Input =22 mA

• Standard Key input = 18 mA

• Mono touch screen = 40 mA

• Colour touch screen = 22 mA

Note *3

If there is no clock present on a C-Bus2 system, and you do not have an alternative device capable of

generating a clock (with its clock enabled) that may be connected to the system then, use learn mode

to enable the clock. Enter learn mode and wait until the unit light and C-Bus light ﬂash alternatively.

This may take a while if after one minute the lights are not ﬂashing alternatively then come out of learn

mode and try again.

Note *4

Conﬁrm you have one burden if suggested by toolkit, (as a general guide if you have less than 70

units you will need one burden).

If you do not have a hardware burden on the network and it appear to have communications

problems, adding a burden may help. If possible add a hardware burden, if not, a software burden

may be enabled using learn mode.
