HeavyDuty technology with enhanced monitoring system (EMS)

Baumer encoders are designed for utmost reliability under most adverse conditions, and the many decades of dependable operation in customer applications give proof of that. However, there are some applications where trust is not enough – regardless of most reliable technology.

Baumer has taken this aspect into account and embedded a function-checking system in their new encoder series HOG 9.2 and HOG 10.2 (fig. 1). Identical in mechanical design to HOG 9 and HOG 10 that have proved absolutely reliable in tens of thousands of applications, the enhanced HOG 9.2 and HOG 10.2 feature the so-called “Enhanced Monitoring System” (EMS). The basis is a rapid micropro-cessor which continuously monitors all encoder functions over the full speed range. Any eventual malfunction or error is quickly and reliably detected. By an alarm output the control is informed of any error occurred. The prevailing operating status is visualized by LED provided at the encoder housing.

But the new HeavyDuty encoders are even capable of more: Long lines and high speed implicating high output frequencies often pose a problem to conventional encoders in transmitting a usable HTL signal. Worst case scenario is even switch off. The new incremental encoders feature improved, optimized power transistors for reliable line driving of incremental HTL signals over long lines and at high frequencies. Transmissions over lines exceeding 300 m in length and at 100 kHz in conjunction with an encoder temperature of 100 °C are no longer a problem.
