Overview
SIRIUS 3UG4815 monitoring relay
Solid-state line monitoring relays provide maximum protection
for mobile machines, plants and hoisting equipment or for unsta-
ble networks. Network and voltage faults can thus be detected
early and rectified before far greater damage ensues.
The line monitoring relays with IO-Link monitor phase sequence,
phase failure (with or without N conductor monitoring), phase
asymmetry and undervoltage and/or overvoltage.
Phase asymmetry is evaluated as the difference between the
greatest and the smallest phase voltage relative to the greatest
phase voltage. Undervoltage or overvoltage exist if the set limit
values for at least one phase voltage are overshot or undershot.
The rms value of the voltage is measured.
■
Benefits
•
Can be used in any network from 160 to 630 V AC worldwide
thanks to wide voltage range
•
Variably adjustable to overshoot, undershoot or range moni-
toring
•
Freely configurable delay times and RESET response
•
Width 22.5 mm
•
Display and transmission of actual value and network fault
type to controller
•
All versions with removable terminals
•
All versions with screw or spring-type terminals
■
Application
The relays are used above all for mobile equipment,
e.g. air conditioning compressors, refrigerating containers,
building site compressors and cranes.

Function
Application
Phase sequence
• Direction of rotation of the drive
Phase failure
• A fuse has tripped
• Failure of the control supply voltage
• Broken cable
Phase asymmetry
• Overheating of the motor due to
asymmetrical voltage
• Detection of asymmetrically loaded
networks
Undervoltage
• Increased current on a motor with
corresponding overheating
• Unintentional resetting of a device
• Network collapse, particularly with
battery power
Overvoltage
•
Protection of a plant against destruction
due to overvoltage
