FAULT ICON
The Fault icon energizes when a fault
condition has been detected by the TB84PH
Advantage Series analyzer. Fault conditions
include all problem and error detection as
outlined in Section 13, Diagnostics.
SPIKE ICON
The Spike Output function modulates Analog
Output One from the normal level
representative of the process variable to a
value configured as a set percentage of output
current. When the TB84PH Advantage Series
analyzer has detected a fault condition and
the Spike Output function has been enabled,
Analog Output One will begin to modulate and
the Spike icon will energize. For more
information on Spike Output and Fault
conditions, see Section 13, Diagnostics.
RELAY ICONS
The Relay icons are composed of three
individual icons. Each icon represents the
specified relay (i.e., Relay One, Relay Two,
and Relay Three.) When a relay change state
from its normal state to an energize state,
the corresponding Relay icon also energizes.
Since the normal state of each relay can be
set by a switch, the relay icon will only
inform the user of a state change and not
whether the relay has closed or opened.
