Product Details
Description
The RCM470LY monitors for ground faults in grounded and high-resistance grounded AC
systems, both single- and three-phase. The RCM470LY is specially designed to provide advanced
warning of developing ground faults without the problems associated with high
sensitivity nuisance tripping.
A wide, steplessly adjustable setpoint range allows for flexibility in a variety of systems. A
DPDT contact allows for both information transmission (such as to a PLC) and power interruption
(such as through a contactor or shunt trip breaker).
Since the values are measured using a special current transformer, the RCM470LY is nearly
independent of the load current and the system voltage. The device can also be used for
busbar systems.
Applications
• Ground fault detection in single- or three-phase AC systems
• Motors and motor control systems
• Generators, portable and fixed
• Alarm systems, safety devices
• Current monitoring of normally offline single conductors
• Cooling equipment with valuable frozen goods
• Industrial controls
• Heat tracing systems
Function
Measurements of the system's ground fault current are taken via an external current transformer.
All phases (including the neutral if one exists) are placed through the current transformer.
The currently measured value (measured as a percentage of the setpoint) is indicated
on the LED bar graph.
If the measured value exceeds the response value, the contacts switch over and the alarm
LEDs activate after the time delay has expired. If the device is set to non-latching mode and
the ground fault clears, the alarms will then clear. If the device is set to latching mode, the
alarms will not clear until the device is reset manually or the supply voltage is lost.
The TEST function allows for an internal operation testing of the device. Settings are modified
via the device's DIP switches and potentiometers.
The connections between the device and the external current transformer are continuously
monitored. If the device detects a connection error, the CT connection monitoring alarm
will activate, and the contacts will change over without delay.
