Alarm Setpoints

A L 4
Up to four alarm setpoints are provided, depending on the options ordered.
In Operator Setup these setpoint values may be examined and changed only if Operator Setup
was enabled under Supervisor Setup (see Enable/Disable Operator Setup). The type of setpoint
(
HI
or
LO
) and state of the relay contact (
STD
or
FSAFE
) may be examined but can only
be changed in Supervisor Setup.
Press
ENTER/SAVE
The display will show
HI
or
LO
to indicate whether the alarm was config-
ured as a high setpoint or low setpoint in Supervisor Setup.
HI
indicates
alarming when the signal is greater than the setpoint value.
LO
indicates
alarming when the signal is less than the setpoint value. This cannot be changed
in Operator Setup.
Press
ENTER/SAVE
Alarm relay state is displayed: either
STD
(standard) or
FSAFE
(failsafe).
Standard outputs use a non-energized relay coil, i.e. the relay coil is energized
to indicate an alarm condition. Failsafe outputs use an energized relay coil, i.e.
the relay coil must be de-energized to indicate an alarm condition. This cannot
be changed in Operator Setup.
Press
ENTER/SAVE
Setpoint value for this alarm is displayed. The bar and digital displays both
indicate value of the setpoint.
Press
INCREASE
DECREASE
INCREASE and DECREASE pushbuttons can be used to change the setpoint
value. Hold it until the new setpoint value is reached.
The longer the pushbutton is held, the faster the display moves to the required
setpoint value.
Press
ENTER/SAVE
To save the new setpoint value, press the ENTER/SAVE pushbutton.
Do not assume that the new value is saved once you have arrived
at the new setpoint value and the BarGraph
™
defaults to normal
display mode. You must press ENTER/SAVE to store the new
setpoint value and make it effective.
Notes: In Operator Setup mode, only the bar and digital displays are affected. All
signal processing functions continue to operate at the current setup val-
ues. Thus, if you are using setpoint relays or retransmit capabilities, they
continue to function as if the BarGraph
™
was in the normal display mode.
