automatic alternating display (→ Fig. 24). If a fault occurs, the display changes colour (blue/red).
See Section 5.3 ’Error message display’ for information on how to eliminate the error.
1. Flow transmitter (Setup Inputs - Flow inputs)
Flow 1
Signal: PFM
K-factor: 8.9
Thermal exp. coeff: 4.88x10
-5
(see example on left-hand side)
2. Pressure sensor (Setup/ Pressure):
Pressure 1
Signal: 4 to 20 mA,
Start value 0.005 bar,

Engineering units: Mass flow t/h, Mass sum t
5. Configure display (Setup/ Display):
Group1: 3 values (mass flow, pressure, temperature)
Group 2: 1 value (mass sum) scrolled: 10 seconds,
Group 1: Yes,
Group 2 : Yes
6. Set up alarm set point:
Relay,
operating mode Min+Alarm,
signal source mass flow,
switch point 15 t/h,
hysteresis 0.5 t/h (this means relay reset at 15.5 t/h)
