Activates… Is not active….
Under Frequency Warning
IEEE 37.2 - 81 frequency relay
Active when the generator frequency falls
below the Low Frequency Warning
Inactive when
• The set is stopped
• During starting sequence before
the safety delay time has expired.
Under Frequency Shutdown
IEEE 37.2 - 81 frequency relay
Active when the generator frequency falls
below the Low Frequency Shutdown
Inactive when
• The set is stopped
• During starting sequence before
the safety delay time has expired.
Under Speed Shutdown
IEEE 37.2 - 14 under speed relay
Active when the engine
speed falls below the
Under speed Shutdown
setting
Under Speed Warning
IEEE 37.2 - 14 under speed relay
Active when the engine speed falls below the
Under speed Warning
setting
User Defined Control 1-3 active
Indicates that the specified User Defined Control (Control Logic) is active
Waiting for generator This output indicates that the engine has been instructed to start but has not
yet become available. Once the generator becomes available this output will
become in-active. (Available = Generator Frequency and Voltage levels are
above the ‘Loading’ levels set in the configuration)
Waiting for Manual Restore
IEEE 37.2 – 3 Checking or
Interlocking relay
Becomes active when the generator is on load and the mains supply is healthy but an
input configured to Manual Restore is active.
This can be used to signal to an operator that action is required before the set can
transfer back to the mains supply.
