NOTE
Conductors A and B carry the signal from the
electrodes, and C is at the potential of the liquid
(signal common). Shields SA and SB are kept
at the same potentials as the individual electrodes (these are actively driven shields.) This is
done to reduce the effect of the distributed
capacitance of the cable at long cable length.
Note that, since the signals from the individual
electrodes are impedance converted inside the
converter, errors will result if they come in
contact with any other component. Great care
must be taken in the cable end treatment.

IMPORTANT
• As this is a transistor contact (insulated type),
give attention to proper voltage and polarity
when wiring.
• Do not apply a voltage larger than 30V DC or a
current larger than 0.2A in order to prevent
damage to the instrument.
• When input filter constant of the electronic
counter is large in relation to the pulse width,
the signal will decrease and the count will not
be accurate.
• If the input impedance of the electronic counter
is large, an induction noise from the power
supply may result in inaccurate counts. Use a
shield cable or sufficiently reduce the input
impedance of the electronic counter within the
electromagnetic flowmeter pulse output specification range.
• The active pulse output (Optional Code EM)
cannot be used in conjunction with the standard
pulse output.
• When the active pulse output (Optional Code
EM) is selected, do not be short-circuit between
the P+ and P– terminals to avoid damaging the
instrument.
• When the active pulse output (Optional code
EM) is selected, the range of pulse rate must
be set to 2 pps maximum.
• To avoid communication (BRAIN/ HART)
failure, it is recommended to use the shield
cable.

BASIC OPERATING PROCEDURES
The modification of data settings from the display unit can be carried out using the three
setting switches (infra-red switches) - namely, the , , and switches.
The infra-red switches enable the user to set parameters without opening the cover.
This chapter will provide a description of basic data configuration and the methods to be
used with the three setting switches. The AXFA11 can also be operated using a handheld
Brain Terminal (BT200) or a HART Communicator. (Please refer to Chapter 7 for operation via Brain Terminal and Chapter 8 for operation via HART Communicator.)
WARNING
Be sure to set parameters as "Protect" on the write protect function after finish of
parameter setting work.
Under extremely rare case, the infra-red switches may respond unexpectedly in
such conditions as sticking ball of water or extraneous substances on the surface
of display panel glass according to the principle of infra-red switch operation.
Its probability rises in such cases as sticking rain water by storm or other similar
situation and washing up work near flowmeter installation place.
Either to illuminate or stop illuminating the infra-red switches by the flashlight may
cause the mis-reaction.
Refer to Chapter 6 "Menu P: Parameter Protection Items" and section "10.2.3"
how to use the write protect function in detail.
(USING THE DISPLAY UNIT)
IMPORTANT
Operate the display unit under the condition where direct sunlight, etc... do not shine
to the setting switches directly when the parameter setting operation is carried out.
NOTE
(1) Always use the setting switches with the cover of the AXFA11 closed.
(2) Use these switches with them covered by the glass window.
(3) If dirt, dust or other substances surfaces on the display panel glass, wipe
them clean with a soft dry cloth.
(4) The operation with dirty gloves may cause a switch response error.

6. PARAMETER DESCRIPTION
NOTE
6.PARAMETER DESCRIPTION
6.1Parameters
With the exception of parameters that were specified
by the customer upon ordering, all of the AXFA11’s
internal parameters will initially be set to default
values. Actions such as the modification of display
details can then be carried out whenever necessary.
IMPORTANT
Make sure to keep the AXFA11’s power on at
least for 30 seconds after you set the parameters. If you turn the power off immediately after
the parameters are set, the settings will be
canceled.
6.2Parameter Lists
Parameter lists are comprised of the following items.
In order to ensure that correct flow rate data can
be acquired, it is crucial that the nominal size,
flow rate span, and meter factor of the combined
remote flowtube are setup. In cases where a
remote flowtube is ordered at the same time as
the AXFA11, the nominal size and meter factor
will be setup upon shipment from the manufacturing plant, and these will not require additional
setting. If the AXFA11 is ordered individually, the
default value will be setup for the meter factor;
accordingly, it will be necessary to change this
setting to the meter factor indicated on your
remote flowtube data plate.
If a flow rate span is specified upon ordering,
this will be set before shipment. If this is not the
case, however, it will be necessary for the
appropriate value to be set up by the user.
