Pinnacle Systems MG - Manual (Page 20)

Operations
NOTE: Examine the MicroGuard on a daily basis to
make sure that no one has moved the light curtain pylons
closer to the pinch point or removed any mechanical
guards from around the curtain.
NOTE: If it is possible for someone to go through the
light curtain and remain in a dangerous area without
having to block the light curtain, you must order the
Resettable Latching Relays option which keeps the
curtain RED even after you are no longer blocking the
curtain. The Latchout reset button is mounted away
from the dangerous area and must be cycled to reset
the curtain.
1) Power up the light curtain. If a fault occurred the
last time the unit was powered and was never
RESET, it will appear as a “SLAVE FOUND” error
message and you will have to push the RESET
button to clear the fault message and start the
curtain.
2) When GREEN the curtain will display “RDY” or
“rdy “ depending on any options that were set (see
Appendix A: Diagnostics and Troubleshooting for
Descriptions).
3) When RED due to blockage, the display will
indicate the location of the first obstruction(s) and
the total size of the obstruction(s) (see Appendix
A: Diagnostics and Troubleshooting). If you have
Floating Blank, then this is indicating that your
object is too large for the floating size you have
selected. If you increase the Floating Blank size,
you must recalculate the safety distance formula
since the object sensitivity will be larger. If you
have the Resettable Latchout option, the display
will show “PENT” to indicate penetration. You
must cycle the Latchout RESET button to clear
the curtain (see Optional Features, “Resettable
Latching Relays”).
4) When RED due to a fault, the display will scroll
the error message that caused the fault and the
board and beam number (if it can be pin pointed).
You must first correct the fault and then push the
RESET button to clear the fault from memory,
even powering down the unit will not clear the
fault from memory (see Appendix A: Diagnostics
and Troubleshooting).
5) If you have the Guarding Mute-Out option, the
display will show “MUTE” during the up stroke.
If you have the Cincinnati Interface hooked up,
the display will show “CINN” during the up stroke
(see Optional Features, “Guarding Mute-Out”).
6) Auto Blank. The display will show “AB” to indicate
that an object is programmed in and its size (in
beams) is shown as the next digit. If you keep
getting a “MOVE” message and your object is
not moving, try repositioning the object slightly
(+/- 1/4”) and reprogram it back into memory. If
you get a “SIZE” message, you must either get
new software to allow a larger object or reduce
your object size.
7) Floating Blank. The display will show “FB” to
indicate the allowed blanking size in beams. Once
an object penetrates the curtain, any second
object will cause the curtain to display “OBST” to
indicate that a second obstruction is in the curtain.
This is done in case you select a Floating Blank
size much larger than the actual object size.
