When an Earth Continuity trip occurs the HPB Relay de-
energises the MCR Relay. The “EC” LED on the
display module is illuminated and the open collector output on the relay is switched on to provide remote
monitoring if required.
The Earth Continuity can be set to be latching or non-latching (See Section 9, User Adjustable Settings).
This allows the user to determine if the fault is manually or automatically reset once the pilot
– earth loop
is healthy. The selection is either “Pilot Latch: On” or “Pilot Latch: Off”.
For Pilot Fault Finding information, see Section 16.1.
