Ventilation of the head
does not work normally
HEAD FAN connectors
on the PCB MCIP are not
ok
Check tension on the
FAN connector (rif. MCIP
PCB)
The lamp is cutting out
intermittently
The lamp is not working
well.
The values reached by
the internal temperature
are too high
The tension of the
power supply is either
too high or too low.
The fan on the head is

Check and if necessary
replace the fan
One of the function is
not working well(ie.
DIMMER)
Disconnect the power.
Manually test if the
DIMMER moves freely.
The stepper motor is
damaged or the cable
connected to the
controller pcb is broken
(ref. MCIP PCB).
The motor drive (L6219)
is broken.
Problem Pilot-tests (guide) Probable cause(s) Suggested Solutions
None of the
MiniCity250s responds
to controller.
The DMX led is switched
off.
Make sure that all the
units are set in DMX
mode.
After the configuration
reset all the fixtures
The controller is not
connected to the
fixtures.
The cable from the
controller to the first of
the MiniCity250 is
interrupted (or pin 2 and
3 are swapped or the
cables are on short
circuit)
Connect the controller
properly.
Use an already tested
cable and connect the
fixtures one by one.
One or more of the
MiniCity250s do not
respond to the controller
or do it wrongly.
The non-working
fixtures are always the
same.
The fixtures work
accidentally. If one of the
connecting cables is
missing this may cause
a random
malfunctioning in
addition to apparent
normal operation. If the
inverted-data is cut wire
is cut (pin. 2 on the DMX
connector) the line
works intermittently.
Wrong DMX address in
the fixture.
Wrong data cables, or
disconnected or shorted.
One fixture has a broken
DMX board.
DMX link not terminated.
Set the proper address
Check and if necessary
replace the cables.
Use a tested cable and
replace only one at a
time.
Use a tested cable and
exclude only one fixture
at a time.
Insert the terminator on
the last fixture (pag.10)
