OVR-15, 27 & 38 LV cabinet Instruction Manual
2.
Complete the physical wiring for power supply with an addition of 2
pole DC MCB of suitable rating in the circuit. Space is allocated on the
inner swing door of the LV cabinet for mounting the MCB.
3.
Hardwire the modem with suitable port of RER615 relay as per
requirement of communication protocol. Modem Antenna can be
connected outside the LV box by routing the Antenna wire thru
bottom gland plate of LV box.
7.
To start capacitor
charging
Put the Service/Discharge selector in the LV cabinet from "Discharge”
position" to "Service" position
8.
Checks and observations
on ACM power ON.
When the AC MCB of Charging device is turned on;
-
ACM will conduct internal checks Initially with both RED and GREEN
LEDs blinking on ACM. It may take around 2 minutes for recloser to
become ready from each initial energization.
-
Successful energization will be indicated by GREEN LED becoming
steady and red LED continuously OFF. It indicates that the ACM
(recloser) is ready for operations.
RER615 relay (on inner swing door) gets powered up with complete lighting of
LCD screen & LEDs on RER615 relay HMI.
9.
AR Ready Indication on
Relay LED
When ACM completes all the internal checks and fully charges the
capacitors; the LED "AR Ready" on RER615 relay turns GREEN, indicating
that the recloser is ready for operations.
(Please refer the approved/as built wiring diagram for detailed description
on RER615 LED indications applicable for your unit)
10.
CLOSE Operation.
For closing the recloser;
-
Confirm the emergency manual trip (K69) handle is reset
-
Confirm the recloser status as OPEN by referring to relay HMI
(dedicated LED or recloser OPEN symbol of the SLD on LCD screen)
and the ON/OFF position indicator on HV unit)
-
Press the (I) button on relay HMI. Relay will display a message "CLOSE
CBXCBR1? YES/NO".
-
Press the ENTER push button on YES option. This closes the recloser.
11.
OPEN Operation
For Opening/Tripping the recloser;
-
Confirm the recloser status as CLOSE by referring to relay HMI
(dedicated LED or recloser CLOSE symbol of the SLD on LCD screen)
and the mechanical ON/OFF indicator on HV unit)
-
Press the (O) button on relay HMI. Relay will display a message "OPEN
CBXCBR1? YES/NO".
-
Press the ENTER push button on YES option. This opens the recloser.
12.
Hot line tag and Close
blocking
-
RER615 relay provides a facility to activate a HOTLINE TAG (HLT), which
if activated, blocks all the possible close commands given from local
(through relay) AND / OR given remotely through SCADA. However,
recloser is free to open by commands from Local / Remote, as well as
on protection trip commands initiated by RER615 relay.
-
When HLT is deactivated, close block is disabled.
-
The activation and deactivation of HLT can be locally done via
dedicated function key ‘F2’ on the RER615 HMI or via remote thru
SCADA. Its status is indicated by the LED placed near the function key.
