UNINTENDED MOTION DETECTION & CONTROL

Model UMDC

When unintended motion detection is required to control a braking device such as a Gripper or Drum Brake on an existing control system, this code compliant (ASME A17.1-2004) retrofit is used as an efficient answer. Meeting all the redundancy requirements of the new code it is compatible will all control systems including microprocessors. This is accomplished by virtue of its unique design and flexibility.

The process begins with the receipt of the job prints. Our application specialists alter these prints to reflect the addition of the UMDC unit. A new print is generated as well as a step by step application guide for that control system. This application guide (Pony Sheet) speeds up the installation time and makes the UMDC cost effective to install by taking the guess work out of the upgrade. Through the use of interface relays the UMDC is adaptable to any control system and braking device.


Interface

Interfacing the Model UMDC is accomplished through a series of parallel connections to terminals and/or relays on the host controller. The controller voltage is matched simply by using the correct voltage relays since their coils are isolated from the logic relay coils. The dry output contacts used to control the braking device are also isolated and can be used by any voltage. The logic used for the Model UMDC is straight forward and simple providing a reliable detection and control system.
