Alarm Indication
The Active Alarm Status screen indicates any active alarms. In addition, the
associated Alarm LED flashes.
For latching alarm outputs, the LED flashes when the alarm condition exists,
and goes to ON when the alarm condition is no longer present if the output has not yet
been reset.
*Resetting 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 (if fitted) or with a
communications command via the RS485 module (if fitted).
Note: Outputs will only reset if their alarm condition is no longer present.
Caution: A reset will affect ALL latched outputs.
Multi-Point Scaling
When enabled (
Mm =
), up to 9 breakpoints can
be set to compensate for non-
linear input signals.
For each breakpoint, the input
scale value (n) is
entered in % of input span,
followed by the value to be
shown (n) 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 ( = ), it can be used to set the displayed value to zero
automatically, by making the PV Offset parameter equal, but opposite to, the current
process variable value. Tare can be initiated via the Digital Input (if fitted), with a
communications command via the RS485 module (if fitted) or by using the following key
press sequence:
Press until the process variable is displayed.
Hold down and together for three seconds until the display shows
?
Release both keys and press within 3 seconds to confirm the request.
The display should read briefly, then begin responding to input signal changes. This
will have no effect on any stored Max or Min values until 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.
