Alarms
Number of Alarms:
Seven alarms are configurable for any supported type.
Alarm Types:
Process High; Process Low; PV-SP Deviation; Band; Control Loop;
Rate Of Signal Change per minute – all with optional minimum duration
and start-up inhibit.
Input Signal Break; % Recorder Memory Used, Control Power High,
Control Power Low.
Duration & Start-up Inhibit
Process High; Low; Deviation; Band; Loop; Rate Of Change alarms have
an optional start-up inhibit function and adjustable minimum duration
time from Off to 9999 seconds before activation.
CAUTION:
If the duration is less than this time, the alarm will not acti-
vate no matter what the value is.
Alarm Hysteresis:
Adjustable deadband from 1 LSD (Least significant display digit) to full
span (in display units) for Process, Band or Deviation Alarms.
Combination Alarm & Events
Outputs:
Logically
AND or OR any alarm or profile event (inc Profile running or
ended) to switch an output. The output can be set to switch on when the
condition is
true, or when the condition is not true.
Profiler Options
Profile Limits:
Number of profiles = 64 maximum.
Total number of segments = 255 maximum (shared by all programs).
Segment Types:
Ramp Up/Down over time, Ramp Rate Up/Down*, Step, Dwell, Hold,
Loop, Join A Profile, End or Repeat Sequence Then End. *Ramp Rate is
not available when profile controls two loops
Time-base:
All times are specified in hh:mm:ss (Hours, Minutes & Seconds).
Segment Time:
Maximum segment time 99:59:59 hh:mm:ss. Use loop-back for longer
segments (e.g. 24:00:00 x 100 loops = 100 days).
Ramp Rate:
Ramp Up or Down at 0.001 to 9999.9 display units per hour.
Hold Segment Release:
Release from menu key-press, At Time Of Day or via a Digital Input.
Profile Starting Point
The first segment setpoint(s) begin from either the setpoint, or current
measured input value, of the controlled loop(s)
Delayed Start:
After 0 to 99:59 (hh:mm) time delay, or at specified day(s) & time.
Profile End Action:
Selectable from: Keep Last Profile Setpoint, Use Controller Setpoint or
Control Outputs Off.
Profile Abort Action:
Selectable from: Keep Last Profile Setpoint, Use Controller Setpoint or
Control Outputs Off.
Power/signal Loss Recovery
Action:
Selectable from: Continue Profile, Restart Profile, Keep Last Profile Set-
point, Use Controller Setpoint or Control Outputs Off.
Auto-Hold:
Off or Hold if input >Band above and/or below SP for each segment.
Profile Control:
Run, Manual Hold/Release, Abort or jump to next segment.
Profile Timing Accuracy:
0.02% Basic Profile Timing Accuracy. ±<0.5 second per Loop, End or
Join segment.
Profile Cycling:
1 to 9999 or Infinite repeats per profile.
Sequence Repeats:
1 to 9999 or Infinite repeats of joined profile sequences.
Loop Back Segments:
1 to 9999 loops back to specified segment.
Segment Events:
Events turn on for the duration of the segment. If events are set on for
End segments, the event states persist until another profile starts, the
user exits profiler mode, or the unit is powered down.
