Voltage Indicator LEDs
|
DeadEasy is a switchboard mounted, voltage indicator led that includes a self test function. It is a non-contact, 3 phase indicator that is primarily used to test for dead and therefore verify safety isolations as part of a lockout procedure.
DeadEasy tests an AC circuit to establish whether the circuit is both energised and de-energised ( alive and dead ). DeadEasy uses Super Bright LEDs so the test result is clear and obvious. DeadEasy provides non-electrical people with a simple and safe method of verifying MCC / Switchboard based, electrical isolations before conducting mechanical maintenance. In addition, confirmation of the de-energised state of the ac phase conductors inside a cabinet reduces the need to open the cabinet to test for dead and hence expose personnel to a potential Arc Flash / Fault. Confirmation of the de-energised state of the circuit inside the cabinet may reduce the level of Arc Flash PPE required to open the cabinet door.
It is simple and fast to use. No licenses are necessary. Anyone can operate DeadEasy, voltage indicator led.
DeadEasy three phase indicator tests the circuit under test by sensing the existence or absence of an electric field surrounding the electrical phase conductors. In essence, DeadEasy is a permanently installed, non-contact, phase indicator. While this testing approach is used extensively in medium and high voltage applications, DeadEasy's focus is low voltage (< 1,000VAC) systems. DeadEasy is switchboard / MCC mounted so that one DeadEasy phase monitor is dedicated to one circuit. It is ideally suited to installation within a motor control centre on controlled circuits. Specifically, on the short length, circuit conductors between the isolating device ( switch or circuit breaker ) and the controlling device ( contactor, soft starter or variable speed drive ).

If you could not view the videos above, DeadEasy non-contact, three phase indicator is operated as follows:
With the Isolator on / closed / 1 the red LED only should be illuminated - Confirms that all 3 phases are energised
With the Isolator off / opened / 0 the green LED only should be illuminated - Confirms that all 3 phases are de-energised
With the Isolator off / opened / 0 and self test activated the red LED only should be illuminated - Confirms that 3 phase voltage sensing is operational and therefore validates the de-energised result achieved in step 2 above.

Electrical Isolation Procedures / Lockout Tagout (LOTO) Procedures often require that electrical switches be tested so as to confirm that the switch is "electrically off" once the equipment has been isolated. Confirmation or verification is often performed on the following isolating equipment:
Typical Isolation Procedure testing methods include:
In many cases these isolation verification methods are complex, potentially misleading and expensive to perform.
DeadEasy, phase indicator exposes unsafe electrical isolations by detecting a failed isolation switch.

In April 2011 a minor change was made to DeadEasy 31 HMI PCB and DIN rail mount electronics PCB to provide better self test performance. The current version is Minor Revision 3. Normally the self test transmit signal path is from the transmitter through the lens cap, bounce off an operator’s hand, return through the lens cap and into the receiver which initiates a self test. We found that in the HMI Minor Revision 2, a portion of the self test transmit signal was passing through the HMI PCB and into the underside of the self test signal receiver. This issue came out of left field as manufacturer’s data suggests only the top face of the receiver will receive signal. The modification involved inserting a copper layer on the HMI PCB to block the bypassed transmit signal. This had the effect of reducing the ambient noise level and allowed us to reduce the self test transmit signal threshold on the DIN rail mount electronics PCB. Users of DeadEasy 31 Minor Revision 2 should not be concerned as the “better self test performance” allows us to identify construction issues better at the time of pre-dispatch testing. The “better self test performance” is imperceptible to an operator. Future purchases will be of Revision 3 units. Changes to the HMI PCB and DIN rail mount electronics PCB, however means that DeadEasy 31 Minor Revision 3 HMI and DIN mounted electronics are not interchangeable with Revision 2 components. The first DeadEasy 31 Minor Revision 3 versions carried the serial number #21D. Serial numbers are hexadecimal. In general, we suggest that HMI PCB and DIN rail mount electronics PCB carrying the same serial numbers be kept together in the installation as they are both from the same construction batch.
