Auto Blank
NOTICE
Place Auto Blank keyswitch
into OFF/RESET position and remove any
obstructions while aligning light curtain.
Do not
use Auto Blank until light curtain is correctly
aligned
(see Installation Procedure, Page 3).
The keyed lock switch is designated to be supervisory
controlled. After installation, the safety key should
be removed and controlled only by the safety
supervisor or authorized plant personnel.
The term Auto Blank is an abbreviation which stands for
automatic programmable beam blanking. Auto Blanking
is controlled by a multi-position keyswitch and has three
distinct modes of operation:
1)
MUST BE RESET IF AUTO BLANK OBSTRUCTION
MOVES OR GUARD PENETRATED
The Auto Blank obstruction must remain in its
exact location permanently. Any movement in
the Auto Blank obstruction and/or additional
guard penetration will latch the light curtain
in a RED condition and must be reset via the
keyswitch.
NOTE: If no obstructions were programmed
in, the guard will still latch in a RED condition
should the guard be penetrated.
2)
MUST BE RESET IF AUTO BLANK OBSTRUCTION
MOVES.
The Auto Blank obstruction must remain in its
exact location permanently. This works like
Mode 1 except guard penetrations will not latch
relays (automatic reset to GREEN condition).

MODE
2
WITH FLOATING
BLANK
This mode works like Mode 2 with the addition
of a Floating Blank which is set to allow a one
beam float (see Floating Blank for description,
Page 6).
NOTICE
If no obstructions were
programmed in, the guard will still allow a one
beam float.
Do not place the moving obstruction in the light
curtain while programming Auto Blank.
The Penetration Depth Factor D(pf) must be set to
account for the one beam float plus Auto Blank (see
ANSI Standard B11.19-2010 D(pf) table, Appendix A).
NOTE: On all modes of auto blanking, Auto Blank
obstruction(s) need not be sequential, multiple
obstructions can be programmed in at one time, but not
exceed a total of eight beams. The Diagnostics Display
will issue a Code 8 if the Auto Blank obstruction(s) is
moved or exceeded the maximum allowable number of
obstructed beams.
Programming.
Turn the keyswitch into the OFF/RESET
position and place the obstruction(s) in the guarded area.
Turn the keyswitch into the desired mode of operation.
You will notice that the Diagnostics Display will change
to show you the total number of beams currently being
blocked by the obstruction(s). This display will last for
about two seconds. If an obstruction was detected, the
display will issue a Code 7 to indicate that it has been
programmed into memory. Keep Auto Blank off until the
light curtain is properly aligned and the unit is GREEN
when there are no obstructions.
Auxiliary Output Contact
The Auxiliary Output Contact option provides either a
N.O. or N.C. isolated (DRY) contact output to signal a
RED condition on the light curtain. This output is used
in conjunction with the standard pair of output relays that
get wired up to the safety circuit of your equipment (i.e.,
stop circuit). The standard relay output is monitored,
but
the Auxiliary Output Contact is NOT monitored
and should only be used as a signal line
(i.e., for
additional PLC monitoring).
The Auxiliary Output Contact is Form C (N.O. & N.C.)
and can handle 5Amps@ 125VAC (not fused). See
Wiring Diagram and Terminals 1-3 for proper usage,
