Banner Engineering STP-9 STP-4 STP-3 STP-2 Test Pieces for Light Curtains

The Banner Engineering STP-2, STP-3, STP-4, and STP-9 Test Pieces for Light Curtains are precision accessories that accompany Banner’s Mini-Screen and Micro-Screen safety light curtains for standardized trip tests, commissioning checks, and alignment verification. Used during setup and maintenance, these test-pieces integrate with Banner’s safety-beam families to validate proper response along the protected zone. The Micro-Screen documentation describes a trip-test procedure where the specified test piece is moved slowly along the defined area in three paths—near the emitter, near the receiver, and midway between them—to ensure the red status indicator activates while the piece is in the beam and the green indicator follows on removal, with guidance to diagnose unexpected indicator activity if needed. The Mini-Screen manuals likewise reference the STP-2, STP-3, STP-4, and related test pieces as essential for system configuration and testing. Together, these models support multiple test-path configurations within Banner’s light-curtain offerings, helping technicians confirm correct protection signaling, floating-blanking behavior, and accurate alignment during installation and ongoing service. For model-specific usage and compatibility with a given light-curtain setup, consult the appropriate Banner Mini-Screen or Micro-Screen documentation for STP-2, STP-3, STP-4, and STP-9 test pieces.
