BLASI – Encoder tester
BLASI – Encoder tester is a compact diagnostic module used to verify the operation of rotary encoders in BLASI automatic doors and barriers. The BLASI – Encoder tester connects directly to the encoder’s A, B and Z (index) channels and shows the signal state with built‑in LEDs, allowing technicians to quickly confirm that pulses are being generated correctly. It supports incremental optical encoders and helps detect missing pulses, phase errors or power‑supply issues on the BLASI operator. With simple terminal connections and a DIN‑rail or board‑mountable body, BLASI – Encoder tester is a practical, low‑cost tool for setup, troubleshooting and periodic maintenance of BLASI‑based door and gate drive systems.
Product Details
BLASI – Encoder tester is designed to simplify encoder validation on BLASI‑type swinging and sliding‑door operators where a rotary encoder provides feedback on motor speed or position. The tester accepts input from a standard incremental encoder, displaying the quadrature A and B channels plus the index (Z) signal via separate LEDs so the technician can visually see alternating pulses when the shaft turns. If the A and B LEDs blink correctly and the Z light flashes once per revolution, the encoder is working; if any channel stays dark or behaves incorrectly, the encoder or its wiring is likely faulty. This makes BLASI – Encoder tester useful both for initial commissioning and for fast fault‑finding in the field.
Typically mounted directly on a DIN rail or small panel, BLASI – Encoder tester runs from the same 5 V, 12 V or 24 V supply used by the encoder and does not require additional software or complex instruments. Its compact size and clear LED indication let service staff check encoder health even in tight control cabinets behind BLASI door operators. By using BLASI – Encoder tester, technicians reduce troubleshooting time, avoid unnecessary encoder replacement and help maintain accurate speed and position control in BLASI‑based automatic‑door systems.
