Manual Relay Testing
Series 782 relays included with GRIDlink supplied enclosures have a Manual (momentary) Test Button to detect the connection to the load.
Also by lifting the lever directly behind the blue button, the user can hold the relay contacts indefinitely. This is typically used when the electrician connects to a load and wants to check circuit continuity or see the BMS respond.
When pressed an orange flag indicates contact closure on NO contacts and contact open on NC contacts.
