FAQ's of HIS 71 Insulation Monitoring Devices:
Q: How does the HIS 71 Insulation Monitoring Device function in electrical systems?
A: The HIS 71 continuously monitors the insulation resistance within single-phase electrical circuits. When the resistance falls outside the selectable range (5 k to 100 k), the device triggers relay outputs and activates LED indicators for immediate fault notification.
Q: What are the main benefits of using the HIS 71 Insulation Monitoring Device?
A: Benefits include rapid fault detection (less than 2 seconds response), adjustable sensitivity, continuous monitoring, and clear LED visual alerts. These features help prevent costly downtime by enabling swift corrective action in industrial and commercial installations.
Q: When should the insulation resistance range be adjusted on the HIS 71?
A: The selectable insulation resistance range should be adjusted during installation or maintenance to match the specific requirements and characteristics of the electrical system being monitored, ensuring optimal sensitivity and fault detection.
Q: Where is the HIS 71 typically installed?
A: The device is designed for DIN rail mounting and is commonly installed within control panels, distribution boards, or machinery enclosures in electrical systems for factories, buildings, and industrial sites.
Q: What is the process for responding to a detected insulation fault?
A: Upon detection, the HIS 71 activates relay output contacts (1 NO + 1 NC), triggering external alarms or devices. Maintenance personnel use the LED indicators to identify the specific fault and take appropriate corrective actions, such as inspection or repairs.
Q: How is the HIS 71 powered and what is its supply frequency range?
A: The HIS 71 operates on a wide input voltage (80-270 V AC/DC) and supports supply frequencies from 47 to 63 Hz, providing versatility across various power systems.
