no additional obstructions.
Depth Penetration Factor is the number used to
compute the distance the light curtain should be placed
from the point of operation (see Installation Procedures,
“ANSI Standard B11.19-2010”).
Diagnostics Display:
RDY Keyswitch is in the lowest position (Floating
Blank is off).
FB Indicates Floating Blank active and the
number of blocked beams.
OBST A second object found in the curtain (only
one obstruction is allowed to float).

Optional Features
Metal Box Controller Module
Emergency Stop Input(s)
Description:
This option utilizes two normally-closed
emergency stop contacts to achieve a Catagory 4
safety level, per EN 954-1. If either or both emergency
stop contacts open, power to the safety output relays is
removed, causing the relays to de-energize and send
a stop signal to the guarded machine.
Application: This protects against a safety switch
contact failure or wiring fault. A contact failure or wiring
short will inhibit the system reset, causing the system’s
Diagnostic Message Display to indicate an Emergency
Stop Input Failure.
Usage: Wire one N.C. contact between Terminal #1 and
#4. Wire the second N.C. contact between Terminal #3
and #4 (located on power supply board). This option
cannot be used with Mute-Out. Alterative option: Wire
first N.C. contact between Terminal #6 and #4. Wire
second N.C. contact between Terminal #7 and #8. This
option cannot be used with Cincinnati or External relay
checking features. To reset ESTOP: Close both ESTOP
inputs, then use the latching relay reset input to clear
ESTOP fault (cycle closure between Terminal #2 and 4).
USB
Description: A USB connector is located on
the inside of the door of the Metal Box Controller.
This connector is used for Software Updates,
Diagnostics, and Monitoring Status (Blockage).
See Appendix D.
Floating Blank
Description:
On a press brake, the Floating Blank permits
the work piece to be placed in the guarded area and can
be moved around as long as it does not exceed the object
sensitivity selected.
A keyswitch by default allows for
zero, one, two, or three beams to be blocked anywhere
in the curtain as long as all the blocked beams are next
to each other. The customer may request different
blanking sizes for different applications. The Minimum
Object Sensitivity (MOS) and the Depth Penetration
Factor (DPF) change when the key switch position
is changed. The DPF is used to compute the safety
distance.
Location of the light curtain from the point of operation
must include the depth penetration factor D(pf)
equivalent to the beam spacing.
Minimum Object Sensitivity indicates the minimum
size required to cause the light curtain to detect an
object even if it is moving (floating). If the obstruction is
slightly smaller (less than .25”) than the stated number,
the light curtain may blink RED/GREEN when the
object is moving in the field of view. If the obstruction
is smaller than the stated number by at least .25”, then
the light curtain will stay GREEN as long as there are

Place Floating Blank keyswitch
in lowest position and remove any obstructions
while aligning light curtain. Do not use Floating
Blank until light curtain is correctly aligned (see
Installation Procedure, “Alignment Procedures”).
The keyed selector 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.
