Description
Coping action
PA. Err.
Parameter setup error
An attempt is made to rewrite a parameter
while parameters are write-protected. (In
the standard model, write-protect feature is
set in OFF and will not appear.)
Can be reset by placing No.1 of display
board SW3 in OFF. (This enables you to
change parameters.)
PA. Err. 1
Parameter error 1
Backup data retained for parameters
has been damaged.
CPU initialization and then reconfiguration
of parameters are required.
PA. Err. 2
Parameter error 2
Some of the backup data retained for
the display mode, accumulate total flow
reading, or resettable total flow reading
have been damaged.
Can be restored with MODE switch, but
the accumulated total flow and resettable
total reading will be reset to 0.
PA. Err. Pu Pulse weight error
Pulse weight "Pu" setting is too small
with respect to meter factor "F" and
conversion factor "H."
Change the setting to an appropriate
value that the relationship between F, H,
and Pu satisfies the following formula:
F
×
H
≦
Pu
≦F×H×10000
2
AnA. Err.
Analog output error
Analog output level is exceeded 120%
of full scale for either reason:
①
Flowrate excessive
②
Analog full scale setting too small
①
:Reduce flowrate.
②
:Select an appropriate analog full
scale setting relative to the flowmeter
specification.
Out. Err.
Pulse output error
Pulse "OFF" width in the factored pulse
output falls short of 1 msec for either
reason:
①
Flowrate excessive
②
Factored pulse width setting too great
①
:Reduce flowrate.
②
:Choose an appropriate factored pulse
width "Pon" relative to the flowmeter
specification.

Battery life
Supply voltage has dropped.
Replace the battery with a new one.
7.5.6 About Error Messages
The electronics unit can be reconfigured for new parameters at your option. However, if some parameters
you set up conflict, or when an erratic condition arises, the LCD display will tell you with an error message
from Table 7.5 below.
