Parameterization of the alarm output:
Function
-
MAX-, MIN- or sensor fault-alarm
Value
-
Trigger value of MAX- or MIN-alarm
Delay
-
Alarm delay from 0.1 to 99.9 s
Hysteresis
-
0.1 % to 99.9 % of measuring range
Operation mode
-
NO = normally opened
NC = normally closed
Parameterization of the pulse output:
Pulse per unit
-
Estimation of flow rate from min. 0.01 to
max. 99.99 pulses per flow rate unit
Time scale
-
According to the time entered in the screen
mask
measuring range
Example:
Measuring range:
40. to 800.0 kg/h
Pulse per unit:
10 pulses/(kg/h)
Time scale:
hour
=>
Pulse rate:
min. 400 pulses/h to max. 8000 pulses/h or
min. 0.11 pulses/s to max. 2.22 pulses/s
The Pulse output should be parameterized in the way that at an averaged maximum flow rate a pulse
rate of 10 pulses/s will not be permanently exceeded.
Changed parameters will be lost by leaving the screen mask. They will be transferred and stored in the
MFI 3000 by the instruction
Extras/Program parameters
