Page 19: Functional Description
HAUBER-Elektronik GmbH Functional description In an explosive atmosphere the vibration monitoring unit HE250 will only be o- pened in a de-energized state. The HE250 type has two limit values Lim1 and LIM2 and the corresponding delay times, which can be adjusted separately. If the defined limit value is exceeded and after the set delay time has expired, the corresponding potential-free switching contact is opened. -
