SIGNAL Optical Safety Edge

Application

The SIGNAL12 is a photoelectric thru-beam sensor for pressure-sensitive safety edges (PSSE) for industrial doors. The emitter and receiver must be plugged into the circular hollow chamber of a rubber profile. If the rubber profile is compressed in the closing movement of the door leaf, the signal at the receiver is reduced and triggers a signal to the evaluation unit.

Self-Checking System

• After the operating voltage is applied, the components and the signal quality are always checked automatically.
• The signal quality is determined by various criteria: the quality of the rubber compound, the door width, the deflection, the contamination, etc.
• The measurement result is displayed with a flash code in the range of 1 to 3 pulses, with the operating limit being reached when the light flashes three times.
• In this case, the rubber profile should be checked for damage and the light channel for dirt. To repeat the diagnosis, briefly disconnect the operating voltage of the safeguard at the front edge.

1 LED-flash = ideal conditions

2 LED-flashes = good conditions

3 LED-flashes = operational limit reached

Innovative Optical System

The new optical system allows for particularly large door widths and improved switching behavior when the door is bent due to wind load.

Reliable Working Principle

Working principle in uncompressed condition. A photoelectrical signal is received.

Working principle in compressed condition. No photoelectrical signal is received.

Universally Applicable

The safety edge can be either connected via a junction box with the door control unit or via a remote wireless box to save the spiral cable. The low-power SIGNAL uses the "duo-switch" detection process to set itself to spiral cable or battery operation. This is done automatically by detecting the operating voltage applied. The result is optimum characteristics for the respective operating conditions.
