Display readout Appears if... What to do
A U T O (Automatic protocol
detection error)
... automatic protocol detection is enabled
but the protocol (Martin/DMX) cannot be
determined because there is no control
data. • Verify that the controller is sending
and the serial link is properly con-
nected.
L E R R (Lamp error) ... the lamp doesn’t ignite within 10 min-
utes of receiving the ‘Lamp ON’ com-
mand. Likely reasons are a missing or
defective lamp, or insufficient AC voltage. • Check the lamp
• Check that the voltage and fre-
quency settings match the local
supply.
M E R R (Memory error) ...the EEPROM memory cannot be read. • Contact Martin service personnel
for assistance.
C S E R (Check-sum error) ...a software upload is unsuccessful. • Reload software, see page 23.
**** ... there is no communication between the
control panel and motherboard. This
readout appears briefly when switching
on the fixture. • Check fuses and replace accord-
ingly.
• Check that cable between control
panel and motherboard is con-
nected properly.
• Reinstall software.
S h E R (Short error) ... the fixture detects the lamp is ON but
no ‘Lamp ON’ command has been
received. This can occur if the lamp relay
is stuck or if the lamp-power feedback cir-
cuit fails. The fixture may be operated but
remote lamp on/off may be effected. • Contact Martin service personnel
for assistance.
H o t (Hot lamp) ... you attempt to strike the lamp within 8
minutes after having switched it off. The
fixture will store the ‘Lamp ON’ instruction
and strike the lamp once the 8 minutes
period has elapsed. • Wait until the lamp strikes.
b T E R (Base temperature error)
H T E R (Head temperature
error)
...there is a malfunction in the base or
head temperature sensing circuit. • Contact Martin service personnel
for assistance.
F b E P (Feedback error pan)
F b E T (Feedback error tilt)
F b E R (Feedback error pan/tilt)
...pan (FbEp), tilt (FbET) or both (FbER)
feedback circuits are malfunctioning. It
will still be possible to operate the fixture,
though it goes into a “safe” mode where
maximum speed is reduced, thus prevent-
ing the fixture from losing track of its
home position (losing step). • Contact Martin service personnel
for assistance.
P A E R (Pan time-out)
T I E R (Tilt time-out)
...the pan or tilt indexing circuit is malfunc-
tioning. The fixture will, after the time-out,
establish a mechanical stop, and continue
to work normally. • Contact Martin service personnel
for assistance.
C 1 E R (Color wheel 1 time-out)
C 2 E R (Color wheel 2 time-out)
F g E R (Fixed gobo time-out)
R g E R (Rot. gobo time-out)
...the magnetic-indexing circuit malfunc-
tions (e.g. sensor defective or magnet
missing). After the time-out, the effect in
question stops in a random position. • Contact Martin service personnel
for assistance.
