Environmental Compliance
Waste Electrical and Electronic Equipment (WEEE) Directive
Panametrics is an active participant in Europe’s Waste Electrical and Electronic Equipment (WEEE) take-back
initiative, directive 2012/19/EU.
The equipment that you bought has required the extraction and use of natural resources for its production. It may
contain hazardous substances that could impact health and the environment.
In order to avoid the dissemination of those substances in our environment and to diminish the pressure on the
natural resources, we encourage you to use the appropriate take-back systems. Those systems will reuse or recycle
most of the materials of your end life equipment in a sound way.
The crossed-out wheeled bin symbol invites you to use those systems.
If you need more information on the collection, reuse and recycling systems, please contact your local or regional
waste administration.

Modbus Communications
1.1
Introduction
Your flowmeter hardware and software (GC3E.MBS) have been modified to provide improved MODBUS
communications. The MODBUS option card provides an RS485 interface with a host system, while the main circuit
board continues to support RS232 communications for use with a PC running PanaView™ software.
Note:
PanaView™ does not support Modbus.
To properly set up the instrument, use this addendum along with the standard flowmeter User’s Manual. This
document shows how to install the MODBUS option card and how to program the modified flowmeter to access this
special feature.
When equipped with the optional MODBUS output card, the flow transmitter can send flow data and diagnostic
information to a flow computer (or SCADA) serially, using a Gould-type RTU protocol. In this case, only the MODBUS
function command, 3 (read multiple registers), 6 (write multiple registers) is valid. The format for the data exchange
is as follows:
•
The send command (initiated by the host flow computer or controller) comes in the form:
[time delimiter]&lt;Addr&gt;&lt;3&gt;&lt;First Register MSB&gt;
&lt;First Register LSB&gt;&lt;Register Count MSB&gt;
&lt;Register Count LSB&gt;&lt;CRC Low&gt;&lt;CRC High&gt;[time delimiter]
•
The response (initiated by the host flow computer or controller) comes in the form:
[time delimiter]&lt;Addr&gt;&lt;3&gt;&lt;Byte count&gt;&lt;Data.........&gt;
&lt;CRC Low&gt;&lt;CRC High&gt;[time delimiter]
The format for the returned data types is as follows:
•
Integer (16 bit Integer) &lt;MSB&gt;&lt;LSB&gt;
1 Register - 16 bit integer
•
Integer (32 bit IntegerI) &lt;MSB&gt;&lt;LSB&gt;&lt;LSB&gt;&lt;LSB&gt;
2 Registers - 32 bit long integer
•
Floating Point (FP) &lt;EXP&gt;&lt;MAN&gt;&lt;MAN&gt;&lt;MAN&gt;
2 Registers - 32 bit IEEE floating point number

Installing the MODBUS Option Card
IMPORTANT: The installation information presented here supersedes the information in the standard flowmeter
User’s Manual.
The modified flowmeter uses the RS485 standard for MODBUS communications. This standard allows up to 32 nodes
(drivers and receivers) on one multidrop network, at distances up to 4,000 ft (1,200 m). To connect the instrument(s)
to the host system, Panemetrics recommends using a 24-gauge (24 AWG) twisted-pair cable with a characteristic
impedance of 120 ohms and a 120-ohm termination at each end of the communications line.
The MODBUS option card must be plugged into either slot 5 or slot 6 of the flowmeter. On the option card, pin 1 is the
[TMT-] inverting or negative connection and pin 2 is the [TMT+] non-inverting or positive connection. To link the
flowmeter to the control system, connect the two wires of the twisted-pair cable from these terminals to the
corresponding terminals at the control system.
Note:
If two MODBUS option cards are installed in the flowmeter, only the card in slot 5 is activated.
1.3
Setting Up MODBUS Communications
To set up MODBUS communications, enter the User Program as described in your Programming Manual. Then, refer to
the menu map in Figure 2 on page 20 and complete the following steps:
Note:

MODBUS Register Map
To request specific parameters from the flowmeter using MODBUS, the control system must enter the appropriate
register number. Only registers 1 through 90 are available for MODBUS communications, while registers 508 through
512 are used by the flowmeter to store the MODBUS parameters. For details, see:
Table 2 on page 5 for a 1-Channel gas flowmeter (GC868, GF868, GM868, GN868, GS868, XGM868, XGS868)
Table 3 on page 6 for a 2-Channel gas flowmeter (GC868, GF868, GM868, GN868, GS868, XGM868, XGS868)
Table 4 on page 8 for a 1-Channel liquid flowmeter (DF868, XMT868i)
Table 5 on page 10 for a 2-Channel liquid flowmeter (DF868, XMT868i)
Table 6 on page 13 for a Sentinel flowmeter.
Refer to Notes on page 8, page 12, or page 15 for information about the numerical references.
Note:
Depending on the type of flowmeter being programmed, some MODBUS register numbers may have zero
readings. If this is the case, those register types are not available for that flowmeter.
Note:
If you request Ch2 or AVE data from a 1-Channel meter, the values will all be zero.

*The complete floating point value is constructed by combining readings from the first register with a second register. An
eight Hex digits number will represent the IEEE-754 hexadecimal floating point value. 32-bit Hexadecimal Representation To
Decimal Floating-Point conversion can be performed if needed.
Example: Reg 14 reading is 44d7, Reg 15 reading is 4000, Mass Flow is 44d74000, which corresponds to 1722.
**The complete Long integer value is constructed by combining readings from the first register with the second register.
Eight Hex digits will represent the Long integer value.
Example: Reg 24 is 0019, Reg 25 is ED30, Hexadecimal Sound Speed is 0019ED30, which is converted to 1699120 decimal.
Taking into account that Sound Speed has 3 decimal places (from the map), it corresponds to a value of 1699.120.

*The complete floating point value is constructed by combining readings from the first register with a second
register. An eight Hex digits number will represent the IEEE-754 hexadecimal floating point value. 32-bit Hexadecimal
Representation To Decimal Floating-Point conversion can be performed if needed.
Example: Reg 4 reading is 44d7, Reg 5 reading is 4000, Volumetric is 44d74000, which corresponds to 1722.
**The complete Long integer value is constructed by combining readings from the first register with the second
register. Eight Hex digits will represent the Long integer value.
Example: Reg 2 is 0019, Reg 3 is ED30, Hexadecimal Velocity is 0019ED30, which corresponds to 1699120 decimal.
Taking into account that Velocity has 2 decimal places (from the map), it corresponds to a value of 16991.20.

Communications Options User’s Guide
Chapter 1. Modbus Communications
1.4.3
Notes for a Sentinel Flowmeter
The Sentinel Flowmeter, when equipped with the optional Modbus output card, can transmit flow data and
diagnostic information to a flow computer or SCADA, serially, using a Gould-type RTU protocol. For security and
audit-trail purposes, the unit must be programmed through the PanaView interface. This means that only the
Modbus function command 3 (read multiple registers), is valid.
Communication parameters: 9600, n, 8, 1
The format for the data exchange is as follows:
•
The send command (initiated by host flow computer or controller) is of the form:
&lt;time delimiter&gt; &lt;Addr&gt; &lt;3&gt; &lt;First Register MSB&gt;
&lt;First Register LSB&gt; &lt;Register Count MSB&gt;
&lt;Register Count LSB&gt; &lt;CRC Low&gt; &lt;CRC High&gt; &lt;time delimiter&gt;
•
The response (initiated by host flow computer or controller) is of the form:
[time delimiter] &lt;Addr&gt; &lt;3&gt; &lt;Byte count&gt; &lt;
&lt;CRC Low&gt; &lt;CRC High&gt; &lt;time delimiter&gt;
Data ………
&gt;
Table 6 on page 13 is the data map for the IGM878 and Sentinel. The refresh rate indicates how often the central
controller updates the memory map, available using the ModBus port. The most time-critical information is stored at
the top of the register. This limits how deep the user has to go into the resister stack to gather the real-time
information. All values are IEEE format MSB first (big-endian).
Note:
Regarding meter status, each bit field indicates the error number from LSB corresponding to E1, and from
MSB corresponding to E32.
Note:
Writing any non-zero value will clear the totals (unless they are locked using TOT LOCK/KEY LOCK switches on
the front panel - per MID requirements).
Note:
Writing to COMP will clear all channels.
Note:
Modbus Registers for the Sentinel LCT or Sentinel LNG Flowmeter, Table 7 on page 17, has some fields with a
grey background. These are currently not supported and will return a value of –1.0.

Swapping the Floating Point
To represent a correct floating point value, you may need to swap the reading from two registers. Some applications
allow you to swap the registers. Some do not.
When using the Modscan32 utility in order to monitor register values, you need to select 03: HOLDING REGISTER (see
Figure 3), select the corresponding communications parameters in the menu item Connection-Connect, and hit OK
to make a connection.

Chapter 2. Modbus Over Ethernet Communications 1
2.2
Setup
The default IP address in setting up the Ethernet option card is Dynamic (DHCP). If it has to be changed to a static IP
address, the instrument must first be connected to the DHCP network.
Note:
The following are setup procedure examples.
2.2.1
Finding the Assigned IP Address
Example:
Find the IP address of a module with Media Access Control (MAC) address 00409d25da0b.
1.
Open a DOS command prompt. Go to the directory containing the executable ruiping.exe.
2.
Type ruiping -e and hit Enter.
Note:
3.
Once the module containing the MAC address has been found, it will be displayed along with the assigned
IP address (see Figure 10). In this example the assigned address is 3.112.161.79.
Stop the process by hitting the Esc key.

Tips for Improving Wireless Data Communications
A suitable installation site should locate the antenna in a transmission path as unobstructed as possible; in the
direction of the associated router.
When a wireless transducer is linked to a router, a yellow LED on the WI-FI option board remains on. Received Signal
Strength Indication (RSSI) is an important indicator of wireless link quality. The higher the RSSI, the stronger the
performance a wireless system can provide. Signal Strength is calculated by a wireless transceiver and can be
viewed on Administration-System Information - WI-FI LAN - Active Settings of the device home page (see Figure 37
on page 56).
If constant interference is present in a particular frequency zone, it might be necessary to change the operational
channel in the WI-FI network. If interference problems persist, try reducing the length of data streams by reading less
registers in one request. Groups of short data streams have a better chance of getting through in the presence of
interference than do long streams.

8. HART 5 Communications
8.1
Introduction
The Panametrics GF868, XGM868, XGS868 and XMT868 ultrasonic flowmeters may be modified to permit two-way
communication with a HART communication device. This requires the installation of a HART 5 option card
in the flowmeter. The option card generates a 4-20 mA analog output signal that can be read by the HART device.
Proceed to the appropriate section for detailed instructions on installing and using the HART option card.
8.2
Installing the HART 5 Option Card
To install a HART 5 option card in your flowmeter, complete the following steps:
WARNING! This procedure should be performed only by qualified service personnel.
1.
Disconnect the main power from the flowmeter.
WARNING! Failure to disconnect the power before proceeding may result in serious injury.
2.
Refer to your User’s Manual for step-by-step instructions, and install the HART option card in Slot 6 for a GF868
flowmeter or in Slot 2 for an XGM868, XGS868 or XMT868 flowmeter.
IMPORTANT: If a MODBUS option card is installed in Slot 5 of a GF868 flowmeter, the HART option card in Slot 6 will be
ignored.
3.
Interconnect the HART option card and the HART device as shown in Figure 53.

Installing the HART Option Card (cont.)stalling the HART Option Card (cont.)
For a GF868 flowmeter, the option card connector is mounted on the card, and the HART device leads should go to
pins 1 and 2 of this connector. As for other option cards installed in the same meter as the HART option card, the HART
device will not recognize any option card installed in Slots 3-5 and it will only recognize option cards installed in Slots
1-2 if they are Analog Input, Analog Output, or RTD option cards.
Note:
For XGM868i, XGS868i and XMT868i flow meters the HART device connections are found on the PCB output
for HART card installed in Slot 2. Note the polarity of signals (pin 1 HART+, pin2 HART- on Figure 54 below.
Figure 54: PCB Output for HART Card
8.3
Flowmeter Software Setup
Panametrics flowmeters that are shipped with a factory-installed HART option card require no special setup
procedures by the user. The meter automatically configures itself for HART communication on startup. However, for
field-installation of a HART option card, the card must be configured in the factory test menu before it will be
recognized by the meter. Thereafter, the initialization will be automatic on startup. Contact the factory for specific
instructions.
In addition to setting up the HART option card so that it is recognized by the meter, the analog output of the option
card may be configured using any of the following methods (if available):
•
The flowmeter keypad
•
Instrument Data Manager (IDM™) software
•
PanaView™ graphical user interface software
•
The HART device
Note:
76
Because HART communication is unreliable at analog outputs below 4 mA, the flowmeter automatically
changes a HART option card analog output configuration of 0-20 mA or OFF to a 4-20 mA configuration
upon startup. Check to make sure that the analog output configuration is set to 4-20mA. If for some reason,
it has not been automatically changed, set it to 4-20mA from the front panel.
Communications Options User’s Guide
Chapter 8. HART 5 Communications
8.3
Flowmeter Software Setup (cont.)
To configure your HART option card analog output using any of the first three methods, follow the instructions in the
appropriate User’s Manual. During configuration, the choice of parameter must be limited to those listed in Table 12.
To use the HART device for configuration of the analog output, refer to the instructions that came with that device.

NOTE: “acf” is reported as “normal cubic feet” in HART. Also, “Mega” units (i.e. mgal/day, mcf/day, etc.) are reported
as standard units x 10^6 in HART. For example, 1 mgal is 1x10^6 gal in HART.
Some flowmeter parameters can only be read by the HART device during startup. Therefore, it is recommended that
both the flowmeter and the HART device be rebooted after any reprogramming of the HART option card analog
output. Failure to do so may result in erroneous information or a communication failure between the flowmeter and
the HART device.
8.4
Using the HART Interface
The HART communications option card installed in Panametrics flowmeters has been successfully tested with the
Rosemount 275 Hand-Held Communicator and the Rosemount AMS Computer-Based Communications Software.
Although some flowmeter functions may be performed using the HART device, many other functions (i.e. data
logging, site file uploading, site file downloading, printing, etc.) must still be programmed by the methods described
in the flowmeter User’s Manual. This is because the HART protocol was developed for use with simple transmitters
and it cannot handle the multitude of sophisticated functions built into the Panametrics flowmeters.
8.4.1
Unit Types
Due to limitations of the HART protocol, only those unit types listed in Table 12 are acceptable. If a meter parameter is
set to any other measurement units, the HART device displays an “Unknown Enumerator, Can not resolve” error
message and may terminate communications entirely. In some cases, both the Hart device and the flowmeter may
have to be rebooted to clear the error. To address this potential problem, the flowmeter has been programmed to
force all measurement units to HART compliant units if a HART option card is detected upon startup.
8.4.2
HART Functions
After HART communications has been properly set up, the following flowmeter functions may be accessed using the
HART device:
•
Static temperature and static pressure
Note:
To view the static temperature or pressure for a channel using the HART device, the fixed value for that
parameter must be assigned to that channel at the flowmeter. See your User’s Manual for instructions.
Communications Options User’s Guide
77
Chapter 8. HART 5 Communications
•

•
Minimum and maximum soundspeed (XMT868 only)
•

•

•
Static density
•
Error handling
•
mA error level (if selected)
•
Clear totals
Note:
Refer to your User’s Manual for a complete description of each of the above functions.
When information is viewed through the HART device, the input variable always appears as either Channel 1
Temperature or Channel 1 Pressure. Although these inputs are not necessarily assigned to Channel 1, the HART
protocol labels all inputs as channel-specific. For example, a Slot 1 analog input that is programmed at the meter as
a temperature input assigned to Channel 1, Channel 2, Both, or Neither is always reported by the HART device as a
Channel 1 Temperature input.
Note:
Inputs cannot be assigned using the HART device. Also, any input assigned as “Special” is always reported
as a Channel 1 Temperature input by the HART device
In addition to the functions listed on the previous page, the following procedures may be performed through the
HART device:
•
Calibration and setup of the HART option card analog output
•
Calibration and some programming of analog inputs, analog outputs, and RTD inputs on option cards installed in
Slots 0 (all), 1 (all), and 2 (GF868 only)
•
Viewing some of the flowmeter’s diagnostic parameters

HART 7 FOR X868I AND GF868 FLOWMETERS
The Panametrics XGM868i, XGS868i, XGF868i and GF868 ultrasonic flowmeters may be equipped for two-way
communication with a HART master. This requires installation of a HART 7 option card into the flowmeter. The option
card is passive, meaning it requires an external power supply and sinks 4-20mA proportional to the programmed
parameter.
9.2
Hardware Setup
9.2.1
Installing the HART Option Card
To install a HART 7 option card in your flowmeter, complete the following steps:
WARNING! This procedure should be performed only by qualified service personnel.
1.
Disconnect the main power from the flowmeter.
WARNING! Failure to disconnect the power before proceeding may result in serious injury.
2.
Refer to the Meter user’s manual for step by step instructions. Install the 703-2001 HART option card into slot 2 of
the XGM868i, XGS868i or XGF868i flowmeter. Install the 703-2003 HART option card into slot 6 of the GF868
equipped with HART main code.
IMPORTANT: If a MODBUS option card is installed in Slot 5 of a GF868 flowmeter, the HART option card in Slot 6 will be
ignored.
9.2.2
Hart Connection Point to Point
Note that the 4-20mA output on the HART option card for the GF868 and XGX868i flowmeters is passive, meaning an
external power supply is required. Connect to the HART communications device as shown below:

Chapter 9. HART 7 Communications
For the GF868 HART flowmeter the connector for wiring is mounted on the card, and the HART device leads should be
connected to pins 1 and 2. Please note that for the GF868 HART model only a limited number of slots and cards are
available. The GF868 HART meter will not recognize any option cards installed in slots 3-5 and only in slots 1-2 if the
option cards are Analog Input, Analog Output or RTD option.
For the XGF868i, XGM868i and XGS868i flowmeters the HART device connections are found on the HART card external
connector that protrudes from the terminal board. The HART card must be installed in slot 2. See below picture for
connection to HART terminal.
Figure 56: PCB Output for HART Card
9.2.3
Hart Connection Multidrop
Multidrop mode allows for several devices to be connected to the same 2 wires and communicate with the HART
master. The meters are typically set to addresses other than 0 and the lop current mode is set to disabled.
In Multidrop mode the devices will communicate with digital HART communications only. The 4-20mA control signal
for the PV is set to a constant 4mA. Note that for each device connected in multidrop mode the current drawn is 4mA,
so for two devices the total current draw from the external supply is 8mA.
After setting each device to a unique address and disabling the loop current mode in the Detailed Setup/HART Setup
menu connected the devices together as shown below.
Figure 57: HART Connection
Depending on the HART master software each device should be recognized with scan set to include the range of
each address.

Communications Options User’s Guide
Chapter 9. HART 7 Communications
9.3
Software Setup
Panametrics flowmeters that are shipped with a factory-installed HART option card require no special setup
procedures by the user. The meter automatically configures itself for HART communication on startup. However, for
field-installation of a HART option card, the card must be configured in the factory test menu before it will be
recognized by the meter. Thereafter, the initialization will be automatic on startup. Contact the factory for specific
instructions.
In addition to setting up the HART option card so that it is recognized by the meter, the analog output of the option
card may be configured using any of the following methods (if available):
•
The flowmeter keypad
•
Instrument Data Manager (IDM™) software
•
PanaView™ graphical user interface software
•
The HART device
Note:
Because HART communication is unreliable at analog outputs below 4 mA, the flowmeter automatically
changes a HART option card analog output configuration of 0-20 mA or OFF to a 4-20 mA configuration
upon startup. Check to make sure that the analog output configuration is set to 4-20mA. If for some reason,
it has not been automatically changed, set it to 4-20mA from the front panel.
To configure your HART option card analog output using any of the first three methods, follow the instructions in the
appropriate User’s Manual. During configuration, the choice of parameter must be limited to those listed in Table 14.
To use the HART device for configuration of the analog output, refer to the instructions that came with that device.

NOTE: “acf” is reported as “normal cubic feet” in HART. Also, “Mega” units (i.e. mgal/day, mcf/day, etc.) are reported
as standard units x 10^6 in HART. For example, 1 mgal is 1x10^6 gal in HART.
Some flowmeter parameters can only be read by the HART device during startup. Therefore, it is recommended that
both the flowmeter and the HART device be rebooted after any reprogramming of the HART option card analog
output. Failure to do so may result in erroneous information or a communication failure between the flowmeter and
the HART device.
Communications Options User’s Guide
85
Chapter 9. HART 7 Communications
9.3.1
Unit Types
Due to the limitations of the HART protocol specification, only the units listed above are acceptable. If the meter
parameter is set to any other unit the HART device will display “Unknown Enumerator: and may terminate entirely. In
some cases, the meter may have to be rebooted to resolve the issue. The 868 flowmeter is designed to limit the units
available if it recognizes a HART card during power on to minimize this issue.
Note:
Note that units must be programmed from the meter side.
9.3.2
HART Functions
The HART 7 interface for the 868 series flowmeters allows for setup of 4 dynamic variables, calibration of the HART
DAC and limited programming of the meter configuration parameters. Note that many of the functions normally
associated with setting up the 868 series meters will still require programming by methods described in the
flowmeters user’s manual.
After HART communications has been properly set up, the following flowmeter functions may be accessed using the
HART device:
•
Static temperature and static pressure
Note:
To view the static temperature or pressure for a channel using the HART device, the fixed value for that
parameter must be assigned to that channel at the flowmeter. See your User’s Manual for instructions.
•
Tracking windows (XMT868 only)
•
Minimum and maximum soundspeed (XMT868 only)
•
2-path error handling
•
Velocity averaging response time
•
Static density
•
Error handling
•
mA error level (if selected)
•
Clear totals
Note:
Refer to your User’s Manual for a complete description of each of the above functions.
When information is viewed through the HART device, the input variable always appears as either Channel 1
Temperature or Channel 1 Pressure. Although these inputs are not necessarily assigned to Channel 1, the HART
protocol labels all inputs as channel-specific. For example, a Slot 1 analog input that is programmed at the meter as
a temperature input assigned to Channel 1, Channel 2, Both, or Neither is always reported by the HART device as a
Channel 1 Temperature input.
Note:
Inputs cannot be assigned using the HART device. Also, any input assigned as “Special” is always reported
as a Channel 1 Temperature input by the HART device
In addition to the functions listed on the previous page, the following procedures may be performed through the
HART device:
•
Calibration and setup of the HART option card analog output
•
Calibration and some programming of analog inputs, analog outputs, and RTD inputs on option cards installed in
Slots 0 (all), 1 (all), and 2 (GF868 only)
•
Viewing some of the flowmeter’s diagnostic parameters

Device Status
The device status bits are a set of general error conditions that map to the operation of the flowmeter. Note these
error conditions are standard to HART but may not apply to every field device. They include:
•
Field Device has malfunctioned due to a hardware error or failure
•
A reset or self-test of the field device has occurred, or power has been removed or applied
•
Field device has more status available
•
PV Analog Channel Fixed
•
PV Analog Channel Saturated
•
Process applied to the non-primary variable is outside the operating limits of the device
•
Process applied to the primary variable is outside the operating limits of the device
Figure 62: Device Status
9.4.2.2
Channel Status
The channel status bits are a set of error conditions relating to the flowmeter measurement process. Refer to the
meter Users Guide for a detailed explanation of the measurement error codes along with possible causes and
actions. The error codes may include:
•
Input Calibration
•
Calibration Failed. Measured input is out of range.
•
E0: No Errors
Problem: No error condition currently exists
Cause: Message appears briefly to confirm that the response to another error condition has resolved the issue.
Action: No action required
•
E1: Low signal
Problem: Poor ultrasonic signal strength or the signal exceeds the limits
Communications Options User’s Guide
93
Chapter 9. HART 7 Communications
Cause: Poor signal strength may be caused by a defective cable, a flowcell problem, a defective transducer or a
problem in the electronics console. A signal that exceeds the programmed limits is probably caused by the entry
of an improper value in the Channelx-Set up-Signal submenu of the Keypad Program
Action: Check the components listed above and check the limit values entered in the Channelx-Set up-Signal
submenu.
•
E2: Soundspeed is out of range
Problem: The sound speed exceeds the limits programmed in the Channelx-Set up-Signal submenu of the
Keypad Program.
Cause: The error may be caused by incorrect programming, poor flow conditions or poor transducer orientation.
Action: Compare the measured sound speed to tabulated nominal values for the gas being used and correct
any programming errors.
•
E3: Velocity Range exceeded
Problem: The velocity exceeds the limits programmed in the Channelx-Set up-Signal submenu of the Keypad
Program.
Cause: This error may be caused by the entry of improper programming data or by poor flow conditions and/or
excessive turbulence.
Action: Make sure the actual flow rate is within &plusmn;75 ft/sec (&plusmn;23 m/sec). Correct any flowcell and/or transducer
problems.
•
E4: Signal Quality is poor
Problem: The signal quality is outside the limits programmed in the Channelx-Set up-Signal submenu of the
Keypad Program.
Cause: The peak of the upstream or downstream correlation signals has fallen below the correlation peak limit,
as set in the Channelx-Set up-Signal submenu. This may be caused by a flowcell or electrical problem.
Action: Check for sources of electrical interference and verify the integrity of the electronics console by
temporarily substituting a test flowcell that is known to be good. Check the transducers and relocate them, if
necessary.
•
E5: Amplitude is poor
Problem: The signal amplitude exceeds the limits programmed in the Channelx-Set up-Signal submenu of the
Keypad Program.
Cause: Excessive levels of an attenuating gas, such as CO2, may be present in the flowcell. Solid or liquid
particulates may be present in the flowcell.
Action: Correct any process, transducer or flowcell problems
•
E6: Cycle Skip/Acceleration error
Problem: The acceleration exceeds the limits programmed in the Channelx-Set up-Signal submenu of the
Keypad Program.
Cause: This condition is usually caused by poor flow conditions or improper transducer alignment.
