OVERVIEW
The ELR…PN is a fully featured, Earth Leakage Relay that can either be easily configured using the built-in pre-defined “Profiles” or tailored specifically to suit the
application. The app^ allows the user to define how the unit should operate (see Function diagrams below) as well as configure and set parameters such as the toroid
ratio, relay logic (i.e. energise or de-energise on trip) and define how the Auto-Reclosure mode should operate. Additionally, the option to set a filter cut-off point can
also be defined therefore allowing the unit to ignore signals above a certain frequency.
Utilising NFC technology allows the unit to be used in a “Passive” mode whereby settings can be made in the app and written to the unit without the need for the unit
to be powered. This feature is useful where a panel needs to be shut down and power removed (for safety reasons) before any work or alterations need to be made.
The user also has the ability to read back the configuration of a unit using the app in order to establish/check the settings. Additionally, it is possible to measure (and
display) the actual leakage current present in the system.
An option to recall previous tripping information (accessed via the Logs option in the app) provides the user with historical data allowing the user to establish a pattern
in the tripping occurrence’s and hence make any necessary adjustments.
