B
Mode
Relay B can be used in a number of ways: as a setpoint
control, or as an alarm. The two settings for Relay B Mode
are
CON
and
FAIL
.
The
CON
setting enables normal setpoint operation for
Relay B. Relay B then operates identically to Relay A, with
settings for setpoint, hysteresis, delay and phasing
appearing in the CONFIG menu automatically. See Figure
4-4 for details.
The
FAIL
setting enables the fail alarm mode for Relay B.
Relay B will then trip on any condition that causes the FAIL
icon to be displayed on the LCD. Using this mode allows the
User to send alarm indications to other remote devices. See
Figure 4-4 for details
