SIGNAL12LP and SIGNAL12ECO

Application

The SIGNAL12 is a through-beam sensor for pressure-sensitive safety edges (PSSE) on industrial doors. Transmitter and receiver are inserted into the circular hollow chamber of a rubber profile. If the rubber profile is compressed as the door leaf closes, the signal at the receiver drops and the processing unit trips.

Automatic signal quality check

• When the operating voltage is applied, the SIGNAL12LP automatically checks its components and the signal quality.
• Signal quality depends on factors such as the rubber compound, door width, deflection and contamination.
• A flash code of 1 to 3 pulses shows the result; three pulses mean the operating limit has been reached.
• In that case, check the rubber profile for damage and the light channel for contamination. To repeat the diagnosis, briefly disconnect the operating voltage.

Only the SIGNAL12LP has the diagnostic display, see comparison below.

Optical system and operating principle

The optical system enables particularly large door widths and improved switching behaviour when the door leaf deflects under wind load.

Universally applicable

The safety edge is connected to the door control either via a connection box or via a remote radio box, which eliminates the spiral cable. Using the “Duo-Switch” method, the SIGNAL detects from the applied operating voltage whether it is running on a spiral cable or a battery and adjusts itself accordingly.
