For longer cable runs, use 5-core screened cable, connecting the
screen to the 0 V terminal. If interference still occurs (lamps
flickering when mains nearby is switched on or off) then it may be
helpful to connect the screen to mains earth. If the +15 V
connection is not being used, then 5-core cable, or 4-core screened
cable may be used. The analogue inputs may not be run in the same
trunking as the mains wiring.
A simple dimmer system. Use the NJD Fade-4 (part code: NJ202)
connected to the analogue inputs of the DP10000. This can be the
basis of a simple, high powered 4-channel light dimmer.
Mimic: The four red LEDs allow the user an instant visual indication
of the channel outputs.
REPLACING FUSES
The DP10000 is fitted with a 10 A fuse on each channel, to
protect the unit from overload. If the fuse fails, check that the
output is not being overloaded (no more than 2300 W is connected
to each output), before replacing the fuse.
In the case of lighting which takes a high surge current (halogen
lamps) it may be necessary to reduce the output loading.
To replace the fuse, disconnect the supply and remove the four
screws that hold the cover in place, and remove the cover. The fuse
is located adjacent to each output terminal. The correct fuse is
F10A 5×20 mm (part code: F128GD) Always use a high breaking
capacity fuse (which has a ceramic case) and ensure that it
complies with IEC127. Replace the cover and the cover fixing
screws.
If the channel remains permanently on after replacing the fuse, then
the triac has been damaged (This may happen in the case of an
extreme overload or short circuit on the output). If this happens the
product should be taken to a dealer for repair. Triacs are not
covered by the warranty, because they only fail if the product has
been misused or overloaded.
