Pulse weight error
Pulse output error
Description
Rewriting a parameter is attempted despite write-
protected. (In standard model, parameter write-
protect function is in the OFF; it will not be
shown.)
Parameter data backup has been lost.
Display modes, accumulated total flow, or reset-
table total flow variable has been lost.
Relative to meter factor“F”and conversion factor
“H,”pulse weight“Pu”setting is too small.
For one of the following two causes, pulse OFF
width in factored pulse output falls short of 1
msec.
① Flowrate too high
② Factored pulse width setting too large
Remedy
Setting No.1 of SW7 off on the
display board cancels this
condition (rewriting parameters
is enabled).
Following CPU initialization,
writing down parameters all
over again is required. (Seek
our service.)
Pressing the MODE switch
restores the normal measure-
ment mode, but variables of
accumulated total flow and
resettable total are reset.
Adjust settings so that F, H,
and Pu satisfy the following
relations:
F × H
≦ Pu ≦ F × H × 10000
In case ① , reduce the flowrate.
In case ② , adjust factored
pulse width Pon to an
appropriate value according to
the flowmeter specification.
