Broyce Control ELRV-30 Quick Start Manual

Type: ELRV-30
True RMS Earth Leakage Relay (Variable) - Type A
q
70mm DIN rail housing
q
Designed to monitor and detect true RMS, earth fault currents (up to 30A) in conjunction with a separate toroid
q
Fast response time of <25mS
q
Digital LED Display shows measured leakage current, various user settings and diagnostics
q
Microprocessor controlled with internal monitoring (self-checking)
q
Sensitivity (I∆n) and time delay (∆t) adjustable using simple 2-button operation
q
"Display" push button allows user to view settings without needing to open the tamperproof cover. The "last recorded" peak
trip current can also be recalled using the same push button
q
Single button operation for "Test / Reset" and connection facility for remote "Test" and "Reset" push buttons
q
Connection for remote lamp facility warning user prior to a trip condition (level adjustable by user)
q
Toroid open and short circuit detection (unit forced to trip during open circuit condition)
q
2 x SPDT relay output 8A. LED indication of user settings / fault condition after unit has tripped

INSTALLATION
•
BEFORE INSTALLATION, ISOLATE THE SUPPLY.
•
Connect the unit as shown in the diagram below (N.B. certain features may not be required and
therefore do not need to be connected).
•
Operational and setting information can be found on the reverse of this data sheet.
This unit should be installed in conjunction with the latest wiring regulations and practices (IEE, etc)

output MUST NOT
exceed 240V~ (For
400V~ units used in
1 3 5
3-Phase installations,
connect the load between
terminal 2 and neutral)

*Cabling:
For distances >1m, use twisted pair cable between
standard
the unit and toroid. Always ensure cables to toroid
output
and remote test / reset switches ARE KEPT AWAY
from mains and data cables in the same installation.
