REM Live RL-4

The purpose of the REM live range Electrical Safety Products is to provide a WARNING OF THE PRESENCE OF ELECTRICITY.

The person performing the work in the isolator or control panel cannot fail to see the flashes immediately upon opening the enclosure door and therefore receives the warning that the equipment still has a potentially lethal condition.

RL-4

The RL-4 is designed to fit inside a control panel or switch and mounts on standard DIN rail.
The RL-4 consists of a polycarbonate enclosure, which contains a series of LED's and a legend displaying the following conditions.
Phase and Neutral indication
Indication of any voltage present between 24v - 700vac and 24v - 1000vdc
A safety message with instructions
The RL-4 contains electronic circuits which connect via terminals and user wiring to a point as close as possible to the point of the electrical supply to be monitored - usually immediately after the disconnect switch.

The concept of operation is that when the power is present, then the LED displays in the RL-4 would be illuminated with some intense, flashing LED's that attract attention. These LED's remain operational until all voltage has decayed to less than 24v on all connections.

The legend on RL-4 advises this person to employ other safety procedures and test further before touching.

Another function of RL-4 is to give a continuous reminder to personnel when working on or near live equipment, for test and maintenance purposes, that the situation is one that needs additional care due to the presence of potentially lethal voltage.

A safety message with instructions

The Micro contains fully encapsulated, triple redundant, electronic circuits and the connection is via a flying lead which connects to the electrical supply as close as possible to the Isolation point - i.e. immediately after the disconnect switch.

The concept of operation is that when the power supply is in the "ON" state then the LED displays on the face of the micro would be illuminated with some flashing LED's to attract attention. These LED's would remain operational until all voltage has decayed to less than 24v on all connections including the Neutral.

So the person performing the isolation can see that the Micro is functional with the power on and see a positive change of state after correct isolation, because Micro-Remlive will continue to give some form of illumination until all voltage connected to it is below 24 volts

REM Live uRL-4 Installation Data Sheet
 

Current, AC or DC, 50 Micro-Amps Maximum

Connect MICRO-REMLIVE to the OUTGOING side of the Isolator / Circuit Breaker, making sure that the connections are Electrically and Mechanically sound and in accordance with current regulations for electrical installations. If the Isolator / Circuit Breaker is rated at more than 300 Amps, or the REMLIVE unit is mounted outside the fault free zone, connect via suitable fuses complying with current electrical regulations for electrical installations. It is recommended that the factory fitted cable of uRL-1 is kept electrically and mechanically separate from other cables and earthed metalwork to prevent any damage during normal operation and life of the device, which may be in excess of fifteen years. Take particular care to secure either side of hinged doors so as to prevent any chance of trapping and damaging the cable.


WARNING ! DO NOT FIT REMLIVE IF THE UNIT OR CABLE IS DAMAGED IN ANY WAY


REPLACE the MICRO-REMLIVE unit if EITHER of the two sets of TWO FLASHING INDICATORS FAIL TO FLASH approximately every 1.5 SECONDS, when a live supply is connected. If uncertain about any application or aspect of fitting or operating REMLIVE, contact the supplier.

On 3Phase installations the Neutral and Earth connections are Optional, however should two phases fail, the indicators will cease to operate if Neutral or Earth is NOT USED. Remlive Limited strongly recommend the use of BOTH NEUTRAL and EARTH connections to ensure 100% availability of the Micro-Remlive Warning Indicator. Using Neutral and earth connections has the added benefit of indicting a voltage above 24volts is present – Neutral to Earth – even when all phase voltages are at zero.
 

In any event Remember!!

LIVE EQUIPMENT CAN KILL. OTHER SAFETY PROCEDURES STILL APPLY. TEST BEFORE TOUCHING.

INSTALLATION

To mechanically install REM live simply clip onto Din Rail (Top Hat)

STANDARDS

REMLIVE is manufactured using modern manufacturing techniques and top quality materials. It has undergone ALL the rigorous tests necessary for it to attain the CUR mark and CE Mark and to ensure that it conforms with the essential protection requirements of EC Directive 89/336/EEC relating to ELECTROMAGNETIC COMPATIBILITY by the application of the following standards: EN 50081 – 2 Emissions. EN 50082 – 2 Immunity.

REM LIVE also conforms with the essential protection requirements of EC Directive 73/23/EEC relating to the safety of electrical equipment by the application of the following standards: EN 61010 Low Voltage Directive.

LIMITATIONS OF USE

REMLIVE is housed in a robust VO Rated special enclosure, which has been selected for its durability and protective, insulation and zero halogen properties. REMLIVE has been designed to fit into enclosures having a suitable IP Rating for the environment in which the installation will normally operate and should ALWAYS be fitted in a accordance with the manufacturer’s recommendations.

REMLIVE – Part No. RL-4E - LED Illumination Sequence

The following sequences are related to the illumination and connection of the Remlive - RL-4E
VISUAL SAFETY WARNING DEVICE

The Two Banks of Three Light Emitting Diodes at either end of the unit will flash approximately every 1.5 seconds if Remlive detects a potential difference above 24Vac / 24Vdc between any two connected cables.
