C 3.x.10 Invert signal
Select:
Off switch closes on every pulse, normally open
On switch opens on every pulse, normally closed
C 3.x.11 Special function
This function is only at output B in devices with 2 frequency outputs
connected to terminals B + D or B + A See Fct. 3.x.11 below
Select:
OFF: switched off
Automatic range: switched on - for indication
Activate status output accordingly
External range: switched on- for external range change
Activate control input accordingly
C 3.x.11 Phase shift
This function is only at output B in devices with 2 frequency outputs
connected to terminals B + D or B + A See Fct. 3.x.11 below
Select:
Off no phase shift
0° shift signal inversion possible
90° shift signal inversion possible
180° shift signal inversion possible
When Fct. C 3.5.6 Polarity is set to "both polarities“, the flow direction
is indicated (e.g. +90° or -90°)
C 3.x.12 Information Displays: Serial No, Software No, & calibration date of the circuit board
xxx.xxx - set for volume or mass per pulse
The lowest settable pulse value is calculated using the formula:
measuring range (in l/s or kg/s) 1
100% pulse rate (in 1/s) 2
1
vol. or mass, see Fct. C 2.x.06 for current output
