2 OPERATIONAL
2.1 GENERAL INFORMATION
This chapter describes the daily use of the C401. This instruction is meant for users / operators.
The display must show BEREIT in order to make valid custody transfer deliveries.
•The C401 may only be operated by personnel who are authorized and trained by the
owner of the installation. All instructions in this manual are to be observed.
•Take careful notice of the “Safety rules, instructions and precautionary measures”in the
front of this manual.
By default, the C401 shows delivery information based on mass. By enabling the volume
calculation functions, the unit can also be configured to show volume deliveries.
On the right side of the display, the selected measurement unit is shown together with
the Volumen or Masse flag for volume and mass indication. Anywhere at operator level,
pressing the ▲or ▼key causes the display to switch from volume to mass, and vice-versa.
2.2 OPERATOR INFORMATION AND FUNCTIONS
When the C401 Dispenser is at Operator level and ready to perform a new task, one of the following
delivery screens is shown, depending on the configuration of the volume calculation functions:
At the top of the screen a status bar is displayed. Below the status bar, the main part of the screen is
used to show the actual process values. These contain the totalized mass or volume for the current
delivery (Gelieferte Menge) and the actual mass or volume flow rate (Durchfluss).
On the right side of the display, the corresponding measurement units are displayed, together with
the Volumen or Masse flag for volume and mass indication. Anywhere at operator level, pressing
the ▲ or ▼ key will cause the display to switch from volume to mass, and vice-versa. After about 20
seconds the display will return to the default unit, as configured in the menu.
When the quantity is shown in units of volume, the temperature, pressure and density at reference
conditions are also indicated.
The status bar contains the following information:
•On the left side of the status bar, the current time and date are shown. This gives the operator
the possibility to verify the correct setting of time and date at any time. If enabled in the
configuration, the clock is automatically adjusted for summer time and winter time.
During a delivery, this indication will change to show the current duration (Dauer) of the delivery.
•On the right side of the status bar, either a text appears or status icons appear, to give
information about the C401.
The text indication includes:
oVerbunden: connected to the Flowmeter
oGetrennt: disconnected from the Flowmeter
The icons show:
oIcon : Indicates the connection to the Flowmeter. When blinking, the connection
is not available (Getrennt), when shown permanently the connection is good
(Verbunden).
oIcon : Indicates an (internal) error status is present.
oIcon : Indicates the unit is ‘unlocked’. When this icon is shown, the C401 is NOT
ready to start a new dispense action as it has been put into service mode.

FW-C401-M_v0105_01_EN.docx
2.4 MAKING DELIVERIES
2.4.1 Powering up
After power-up, the C401 will show the BEREIT status on the screen, together with the delivered
quantity (initialised to 00000.000) and the current flow rate as given by the Flowmeter.
Depending on the configuration of the volume calculation functions, the display either starts
with Masse indication or Volumen indication.
2.4.2 Zeroing the flowmeter
After each power-up, the flowmeter needs to be initialised. This is automatically done by the C401
by sending the Zeroing command to the flowmeter every time a new delivery is started.
The Zeroing process is also started manually when the operator presses the 00 /◄key
in BEREIT status. The process usually takes about 90 seconds to complete and cannot be
interrupted, nor can the operator cannot perform any operation on the C401 during that time.
During the zeroing process, the ZEROING status is shown on the display. However, when
initiated by starting a new delivery, the first few seconds of the zeroing procedure will be used to
show a checker-field on the display to indicate that it is working correctly.
At the end of the Zeroing process, the flow rate will display zero (0). If the Zeroing process was
initiated by the start of a delivery, the C401 continues in LIEFERN status. When it was initiated
by the operator, the C401 will return to the BEREIT screen.
If the Zeroing operation was not successful (e.g. when the flowrate was not set to zero), an error will
be displayed.
The C401 waits for the flowmeter to finish the Zeroing process. If this fails, a 2 minute
timeout on the Zeroing process guarantees that the Zeroing process will always finish.
The time and date are normally configured by the installer and are internally updated
by a backup battery. In the rare event that the C401 starts up with an uninitialized
clock, this needs to be corrected before any delivery can be performed.
Please see paragraph 6.3: Changing or initializing an uninitialized clock on how to
correct this error.

Page 10
FW-C401-M_v0105_01_EN.docx
2.4.3 Delivery
When the C401 is in BEREIT status, a new delivery can be started by the operator by pressing
the START key. The date and time shown on the display will change to show the duration (Dauer) of
the delivery.
During the LIEFERN and KOMPLETT status, pressing the ▲or ▼ key causes the
display to switch between Masse indication and Volumen indication.
A delivery starts with the zeroing of the flowmeter (see previous paragraph).
When the initialisation is successful (flow rate should be zero), the delivery total is initialised, the
C401 enters the LIEFERN status and the operator can open the manual valve.
When the valve is opened, the delivery total starts incrementing and the actual flow rate is
continuously updated and shown on the display.
When the required amount is dispensed, the delivery is stopped by the operator by pressing the
STOP / CLEAR key. The C401 will now enter the BEENDEN status in which it waits for the flow rate
to drop down to zero (0). This is also the moment at which the operator must close the manual valve
within 5 minutes.
When the flow rate has reached zero (0), the C401 will enter the KOMPLETT status: the delivery
is completed and a delivery summary is shown indicating the delivered quantity, the duration of the
delivery and the unique delivery number (Lieferungsnummer).
When the operator presses the STOP / CLEAR key at this point, the C401 will return to
the BEREIT status.

Page 11
FW-C401-M_v0105_01_EN.docx
2.5 FORCED STOP
If, for some reason, it is not possible to return the flow rate to zero (0), the C401 will wait 5 minutes
before signalling a warning:
At this point, if the operator is able to stop the flow, the delivery will be finished without any error.
If the operator is not able to stop the flow, he can overrule this demand and force the delivery to stop
by pressing the STOP / CLEAR key for several seconds. The delivery will be finished and stored with
the delivery status ‘Forced stop’ (Zwangsstop).
2.6 ERROR INFORMATION
If an error occurs during a delivery, the error is logged and the delivery itself is marked as faulty. All
error information can then be reviewed in the error logbook and delivery logbook.
The presence of an error during a delivery is indicated by showing a large alarm symbol on the left
side of the screen. When the delivery is finished, the delivery summary will show the delivery status
with an error. In below example, the door was opened during the delivery, which raised an error:
The delivery summary only shows basic (textual) error information. If several errors are present, the
most severe error is shown, allowing the operator to determine if further investigation of the error is
required. For errors with a severity level higher than level 4 (Eich Schloss), it is recommended to
inspect the Int-error field in the delivery record as indicated in the following paragraph.
When the flow rate monitoring function is enabled, a flow alarm is indicated in the following way:
Although the low-flow limit (Low-Flow Grenze) and cut-off limit (Abschaltgrenze) flow alarms can
indicate a certain problem, these situations can also occur during a normal delivery process or basic
operations by the operator. Therefore, its occurrence does not trigger an error nor will a delivery be
marked as faulty.

Error fields
Description
Int-Error
Error status of the delivery.
This field contains a bitfield for the following error-bits:
0x0001 An error occurred during the delivery.
This can either be an error indicated by the Flowmeter or an (internal)
error of the device.
0x0002 Flowmeter error during zeroing procedure
0x0004 Flowmeter error during delivery
0x0008 The delivery was forced to stop by the user.
This generally happens when the flow does not reach zero within 5
minutes after the stop request and the user performs the forced stop
after this time.
0x0010 The device was powered down during the last delivery
0x0020 During the delivery, the connection with the Flowmeter was lost.
0x0040 The service mode was enabled at the beginning or during the delivery.
0x0080 The metrology lock was disabled at the beginning or during the
delivery.
0x0100 The door of the C401 was open at the beginning or during the
delivery.
0x0200 This bit indicates that at the end of the delivery, communication with
the Flowmeter was restored and is only valid if the connection lost
error (0x020) is also set.
If this bit is set, it means that when the delivery was stopped, up-to-
date counter and error-values were available from the Flowmeter.
If this bit is not set, it means that when the delivery was stopped, no
up-to-date counter and error-values were available from the
Flowmeter and the delivered quantity should be reviewed.
0x0400 As an exception, the clock has been set with access level user. Under
normal circumstances, the clock can only be set with access level
installer or higher.
Error-bits are OR-ed together in the error field.
E.g. error 0x0011 shows there was an error (0x0001) and the error was caused
by a power failure (0x0010).
