Alarm Indicaon
The Acve Alarm Status screen indicates any acve alarms. In addion, the
associated Alarm LED ashes. For latching alarm outputs, the LED ashes when the
alarm condion exists,
and goes to ON when the alarm condion is no longer present if the output has not yet
been reset.
*Reseng Latched Alarm Outputs
Any latched outputs can be reset whilst the Process variable or Alarm Status screens
are displayed, by pressing the or key, via the Digital Input or with a
communicaons command via the RS485 module (if ed).
Note: Outputs will only reset if their alarm condion is no longer present.
Mul-Point Scaling
When enabled (Mm PS =
EnAb), up to 9 breakpoints can
be set to compensate for nonlinear
input signals.
For each breakpoint, the input
scale value (ScALn) is entered in % of
input span, followed by the value to
be shown (diSPn) in display
units.
Each breakpoint’s input scale value
must be higher than the previous
value, but the display values can be
higher or lower. Any scale value set to
100% becomes the last in the series.
Tare Feature
When Tare is enabled (TARE = ENAB), it can be used to set the displayed value to zero automacally,
by making the PV Oset parameter equal, but opposite to, the current process variable value. Tare
can be iniated via the Digital Input (if ed), with a communicaons command via the RS485
module (if ed) or by using the following key press sequence:
Press unl the process variable is displayed.
Hold down and together for three seconds unl the display shows YES?
Release both keys and press within 3 seconds to conrm the request.
The display should read 0 briey, then begin responding to input signal changes. This will have no
eect on any stored Max or Min values unl they are reset. Once Reset the Max and Min value will
follow the displayed value that has gone through the tare process
Note: Tare request is aborted if this sequence is not followed exactly.
