User Interface Large 4 character 7-segment display for measured
value, with alphanumeric dot matrix characters for
units, information and programming. Easy to use four
button user interface for programming.
Current output
(optional 1 or 2 outputs)
Selectable 0-20mA or 4-20mA operation into a 1000Ω
maximum load, fully isolated to 2kV. Selectable
transmission of either sensor reading or temperature,
and software scalable within the operating range.
Can be configured as a clean output so that the signal
switches between 0 to 20mA.
Operator adjustment
(Current)
±1mA zero and ±1mA span for remote monitor
calibration
Set Point Relays
(2 standard, 4 optional)
Fully configurable set points with volt free contacts.
Rated 5A 30V DC / 5A 250VAC (non-inductive).
Operating Modes
(Relays 1,2 & 3)
Configurable High, Low, Band or Latch trigger
conditions, with On/Off, Time Proportioning, Pulse
Proportioning, and Cleaning modes for each relay.
Adjustable delay timers up to 10 mins, and hysteresis
in On/Off mode. Adjustable dose alarm timer to 15
mins in all modes. Adjustable cycle time and band in
“Proportioning” modes. Adjustable duration, recovery
and interval periods in “Cleaning” mode.
Operating mode
(Alarm relay 4)
The relay can be set to energise on any one of the
following instrument conditions:- Sensor alarm, Dose
alarm, Calibration, Off line, Any error
Off-Line Facility
(for calibration and
commissioning)
Initiated by remote contact closure or software
selection. Relays 1, 2 & 3 are de-energised and the
current outputs are held at the last On-Line value.
