Metal Box Controller and Light Curtain
Blanking Options

"Auto-Blank" also eliminates the need to count beams and to locate where and what beams are to be shut off to obtain the correct beam elevation to accept an obstruction. This information is displayed on the message display of the controller. "Auto-Blank" will also watch the obstruction and if it moves or is removed, will go into a "machine stop mode" to prevent further machine operation. This is an additional safety feature not available on manually blanked units. These features truly enhance production while providing the ultimate in safety.

When the key switch is turned to the "Auto-Blank" function, the "External Diagnostic Message Display" will show the number of blocked beams and where the obstruction is in the light curtain, then verify that the obstruction is being monitored. This is required information for the depth penetration factor and for proper installation of any safety light curtain.

The versatile "Auto-Blank" (AB) Blanking Series includes:

• Constant scan light curtain
• One Beam Floating Blank built-in plus "Auto-Blank" capability
• Two "Auto-Blank" Modes - up to 8 beams blanked but need not be sequential
  A. One "Auto-Blank" mode with a keyed manual reset when the guarded zone is penetrated
  B. One "Auto-Blank" mode with an automatic reset when the guarded zone is penetrated

Floating Blank (Reduced Resolution) - (8K) Option The "Floating Blank" or "Reduced Resolution" option provides the flexibility necessary to effectively guard all types of equipment that require multiple floating beams. This is quite common in the fabricating industry where the work piece moves.

The "Floating Blank" permits work pieces to be formed vertically or horizontally through the guarded area without shutting down the machine. Entry into the protected area by the operator or passerby will prevent the start, or if the machine is in motion will provide a signal to stop the machine.

The "Floating Blank" is controlled by a keyed selector switch that will allow a work opening of 2" (5.08cm) based on 1/2" (1.27cm) increments. This information is displayed on the message display of the controller. Blanking adjustments required when die heights change are not necessary. The "Floating Blank" light curtain automatically adjusts to the various feed positions providing protection with production.

The "Floating Blank" (8K) Option Includes:

• 1/2" (1.27 cm) - Constant scan light curtain
• 1" (2.54 cm) - One floating beam
• 1-1/2" (3.81 cm) - Two floating beams
• 2" (5.08 cm) - Three floating beams
