Configuring Digital Outputs DO
The following functions can be read and set via the submenus of
the digital outputs menu:
•
The status of the output relays (RELAY OUTPUTS1 and 2)
•
The forcing of the output relays (RELAY OUTPUTS1 and 2)
(only if Force = ON):
– Forced control (0 or 1) of the Trip relays
– Forced control (0 or 1) of the Alarm relays
– Forced control (0 or 1) of the IF relay
•
The configuration of the output signals to the output relays. The
configuration of the operation indicators (LED) Alarm and Trip
and application specific alarm leds A, B and C (that is, the output
relay matrix).
NOTE:
The amount of Trip and Alarm relays depends on the relay
type and optional hardware.
Protection Menu Prot
The following functions can be read and set via the submenus of
the Prot menu:
Reset all the counters (PROTECTION SET/ClAll)
Read the status of all the protection functions (PROTECT
STATUS 1-x)
Enable and disable protection functions (ENABLED STAGES
1-x)
Define the interlockings between signals (only with SetPointPS).
Each stage of the protection functions can be disabled or enabled
individually in the Prot menu. When a stage is enabled, it will be
in operation immediately without a need to reset the relay.
The relay includes several protection functions. However, the
processor capacity limits the number of protection functions that
can be active at the same time.
