Rishabh ELPR Operating Manual

ELPR Operating Manual and Installation guide
ELPR is earth leakage detection and a protection device
used in electrical installations to measure leakage current
occurs due to punctured or weak insulations or contact to
live parts. Earth leakage current is measured through CBCT.
1CO Relay is provided to disconnect breaker and
additional 1NO configurable relay for alarm / fail safe
purpose is provided, CBCT open detection feature ensures
that no false measurement is made. LED indicates Leakage
current ( bargraph ),relay state, CBCT connections.
Two models Smart, Smart+ models are available.

Installation:

Installation to be carried out by qualied person along
with life protecting equipment to prevent hazardous shock
Isolate incoming supply before connection.
Do not expose device to Rain, Dust environment.
Keep at least 10-15 mm distance on both sides of device.
Do not install near Vibrating environment.
Do not install near Heat source.
Install Fuses of 2 Amp in series with supply.
Use Sealing provision to protect from unintentional
adjustment.
Dimensions :
90 x 65 x 35 mm As Per DIN 43880

Mounting:

To mount the device it should be fastened to a standard 35mm DIN rail
(DIN50022). Key hole is provided for wall mount . follow steps to mount
and unmount the instrument
Step1 - Push
Step2-Push clip
up for click fit
Mounting On DIN rail

Connector details:

Use proper screw driver so that sufficient
but not excess force is applied.

Key operations : Separate Trip and Reset keys are provided
1. Trip key - Pressing of test key ( > 3 second ) and holding till
release of key triggers fault condition of relay contacts.
2. Reset key - Pressing key ( > 3 second ) reset / clear the fault
relay condition if fault current is within normal current range.
This key has memory function till power fail of instrument.
Potentiometers operations :Potentiometers are provided for
1. Leakage current (In) - To set Leakage current in Ampere
2. Trip time setting (T-DLY) - Fault sustain time in seconds before
relay driven to fault state.
DIP switch : DIP switch is provided in Smart+ model only
ELR relay configuration - En / D-En,
Relay 2 configuration - Alarm or fail safe
Leakage Fault reset mode - Automatic with 3 retry or Manual reset
