AutoBlank data corrupted
The number of beams found blocked during
programming is no longer equal to the number
found in memory. This may indicate that the
object moved just as it was being programmed
in memory.
CPU clock failure
MASTER has a bad on-board clock circuit in the
CPU.
Emitter firing at wrong time xxy
An LED in the Emitter pylon was firing even
though it was not told to do so. Could be a short
circuit in the emitter pylon or a faulty circuit on the
computer board.
Emitter length fault xxy
The length of the Emitter pylon was detected as
different from the jumpers S3 set on the door
of the Controller Module. xx indicates board
number in 4” increments from circular connector;
y indicates beam number of that board (1 to 8).
Check for a disconnected cable, missing jumper in
the pylon, or a faulty circuit on the computer board.
External contact short
External relay checking option has detected that
the external contact did not close during a cycling
of the curtain from GREEN to RED. Second relay
is able to shut down the system.
External contact welded or wire cut
External relay checking option has detected that
the external contact did not open within .25sec of
the curtain going RED. Second relay is able to
shut down the system.
Fault Display Messages
Resetting Faults: To reset a fault message, push the
FN1 button located on the top of the Controller Module
and wait for the message to finish scrolling. Powering
down will not clear out faults
All faults appear as scrolling messages. Numbers may
appear at the end of the message to indicate where the
fault occurred in the pylon itself.
42-002/3 R28
Software Revision numbers needed during
service (42-002 MASTER chip; 42-003 SLAVE
External infrared source detected xxy
Whenever the curtain is RED (at power up) the
unit checks for external sources of infrared that
might interfer with normal operation of the curtain.
xx indicates board number in 4” increments from
circular connector; y indicates beam number of
that board (1 to 8). This could also indicate that
the detector circuit is faulty.
FLIP
MASTER microprocessor is getting intermittent
blockage of the curtain due to weak signals and
is flip-flopping between GREEN and RED. Re-
align the pylons.
Illegal code
MASTER has come across an illegal machine
language code inside the ROM of the CPU (this
could indicate a bad CPU chip).
Improper operation
MASTER has determined that there has been
an improper operation in the CPU and has reset
for safety.
Initializing memory
The SLAVE has determined that the EEPROM
memory chip does not contain the proper setup
values and will attempt to initialize it. This
message should only occur during the first time
power up. If you get this any other time, it could
mean a faulty memory chip or a glitch in the power.
Internal relay bad/missing
One of the Internal relays has a contact that is not
open or closed and is determined to be missing.
Check for faulty relay contacts or relay position
circuitry.
Internal relay is not energizing
Internal relay was told to turn but the contact
never closed. Check for a faulty relay or a faulty
driver circuit.
Internal relay is stuck on
Internal relay contact has not opened up when
requested to do so. Check for a faulty relay,
welded contact, or a faulty driver circuit. Second
relay is able to shut down the system.
MBLK
MASTER has detected that the pulse width
coming from all the receivers is too wide and has
determined that the pylons are too close together
( < 1’ ). Turn the pylons away from each other
slightly.
