Warning!
Switch off power supply before manipulating the coil current
cable, coil current cable connector or measuring electronics
boards!
Remote version:
1.
Check wiring of terminals 41/42
2.
Check coil current cable connector.
Compact and remote version:
Replace measuring electronics boards if necessary

The temporarily buffered flow portions (measuring
mode for pulsating flow) could not be cleared or output
within 60 seconds.
1.
Change the upper or lower limit setting, as applicable.
2.
Increase or reduce flow, as applicable.
Recommendations in the event of fault category = FAULT
MESSAGE (

• Configure the fault response of the output to "ACTUAL
VALUE" so that the temporary buffer can be cleared.
• Clear the temporary buffer by the measures described under
Item 1.

within 60 seconds.
1.
Increase the setting for pulse weighting
2.
Increase the max. pulse frequency if the totalizer can handle
a higher number of pulses.
3.
Increase or reduce flow, as applicable.

S: PULSE RANGE
!: # 359 to 362
Pulse output:
the pulse output frequency is out of range.
1.
Increase the setting for pulse weighting
2.
When selecting the pulse width, choose a value that can still
be processed by a connected counter (e.g. mechanical
counter, PLC etc.).
Determine the pulse width:
– Variant 1: Enter the minimum duration that a pulse must
be present at the connected counter to ensure its
registration.
– Variant 2: Enter the maximum (pulse) frequency as the
half "reciprocal value" that a pulse must be present at the
connected counter to ensure its registration.
Example:
The maximum input frequency of the connected counter is
10 Hz. The pulse width to be entered is:
a0004437
3.
Reduce flow.
No.
