Correction Factors to Metered Volume
Supercompressibiity Factor Fpv
1.3.1 Correction Factors to Metered Volume
Ideal or perfect gases follow the relationship of Boyle’s Law for pressure effect and Charles’ Law for temperature effect, which can be stated: The volume of any definite weight of a perfect gas varies inversely with change in absolute pressure and directly with change in absolute temperature. The equation for this relationship of the two laws is expressed as follows:
The Symbols V1, P1 and T1 refer to the original volume, pressure and temperature while V2, P2 and T2 refer to the volume, pressure and temperature of the new or changed conditions. Rearranging the equation and rewriting subscripts, we can express it as follows:
Where:
Vb = gas volume (cu. Ft.) at base condition corrected
Pb = absolute base pressure (psia)
Tb = absolute base temperature (deg. R)
Vm = gas volume metered (cu. Ft.) uncorrected
Pm = absolute meter pressure (psia)
Tm = absolute meter temperature (deg. R)
Honeywell

1 About EC 350
1.3 Theory of Operation
1.3.2 Pressure Factor Fp
The pressure factor (Fp) to apply to metered volume is expressed by the Boyle’s Law relationship as follows:
Each increment of meter pressure represents a different pressure factor. As the flowing gas pressure (Pm) changes, the EC 350 automatically applies the pressure factor (Fp) to the metered volume (Vm).
1.3.3 Temperature Factor Ft
The temperature factor (Ft) to apply to metered volume is expressed by the Charles’ Law relationship as follows:
Each increment of meter temperature represents a different temperature factor. Therefore, as the flowing gas temperature changes, the EC 350 automatically applies the temperature factor (Ft) to the metered volume.
1.3.4 Supercompressibiity Factor Fpv
Gases actually behave slightly different than what the ideal gas laws indicate. This deviation depends on the molecular composition of the gas and the specific gravity as well as the pressure and temperature.
Natural gas, for instance, compresses by a greater amount than that computed by Boyle’s law and hence the term “supercompressibility” is used for this deviation. It is small at very low pressure, but becomes substantial as the pressure increases. The EC 350 automatically applies the supercompressibility factor and therefore the equation for total volume correction that the EC 350 applies to metered volume, is expressed as:
Where:
Vb = gas volume (cu. Ft.) at base condition corrected
Vm = metered volume read from meter index
Fp = pressure factor
Ft = temperature factor
Fpv = supercompressibility determined from NX-19 or AGA-8
Honeywell

1 About EC 350
1.3 Theory of Operation
The EC 350 automatically squares the supercompressibility factor displayed, which is based on the pressure and temperature sensed at the meter. The resulting volume readout is corrected for pressure, temperature, and supercompressibility.

2.7 Power Supply Options
2.7 Power Supply Options
The EC 350 has flexible power supply options. The unit can operate from an externally supplied DC power source or from a 4-cell Alkaline, a 2-cell Lithium, or dual 2-cell Lithium Battery Packs.
Low battery/ External Power shutdown mode
2.7.1 External Power Supply
The input voltage range for using an externally supplied DC power source is +5.0 VDC to +15.0 VDC. The
Honeywell power 9 VDC pack p/n: 40-2291 can be used as an external voltage source.
Connections for the external supply are made at the TB1 connector on the EC 350 IO Board. Terminal-1 nearest the top of the IO Board is GND and Terminal-3 is the positive (+) input. When operating from an externally supplied DC power source, a backup battery pack may also be installed with the intent of powering the instrument in situations where the external (remote) power is interrupted.
Installations requiring CLASS 1 - DIV 2 approval, the following Battery Packs are approved: 40-6048 (2cell Lithium), 40-6050 (4-cell Alkaline), and 40-6064 (4-cell Alkaline with 47 ohm Res). These Battery
Packs can be connected to the P5 Battery connector using cable p/n: 40-6045.
Installations requiring CLASS 1 - DIV 1 approval, only the Battery Pack 40-6064 is approved.
When operating from an externally supplied DC power source, configure the External Supply Low Alarm
Limit (Item 795) to be a value greater than 5.0 and generally less than 7.0 V. The default value of Item
795 is -1.0 to effectively disable the Alarm Item 796. The External Supply voltage is measured on a 10 minute interval. Three consecutively low readings are required to the trip the Low Voltage Alarm (Item
796) – this is done to help guard against falsely setting alarm due to a power supply glitch.

2.7 Power Supply Options
2.7.2 Battery Powered
Connections for the Battery pack are made at the P5 connector on the EC 350 IO Board. There are three
Battery choices for operating the EC 350 from battery power:
40-6050 (4-cell Alkaline) – 5 year operating life under specified conditions
40-6048 (2-cell Lithium)
Dual set of 40-6048 (2-cell Lithium) – extended life or heavy usage / comms applications.
Use the Battery Type (Item 1061) to select the type of Battery pack that is being used to power the instrument.
0= 4 Cell Alkaline (default type)
1= 2 Cell Lithium
2= 4 Cell Lithium (dual set of p/n 40-6048)
The Battery voltage is measured on a 10 minute interval. Three consecutively low readings are required to the trip the Low Voltage Alarm (Item 99) – this is done to help guard against falsely setting alarm due to a supply glitch.
Note: The Low Battery Voltage Alarm (Item 99) will not set if an External Supply voltage is present at
TB1 with a voltage level greater than the Battery voltage by over 1.0 VDC. When a Low Battery Voltage
Alarm is tripped (set), an Alarm Log record entry is generated along with updates to time stamp Items
462 and 463.

2.8 General Wiring connections
2.8 General Wiring connections
This section describes the pulse outputs from EC 350.
Three Form-A volume pulse outputs
One Form-B alarm output
These outputs are electronic switches. The first three pulse outputs are configured as either corrected volume or uncorrected volume. The fourth pulse output is used only for alarm output.
Note: Outputs are conventionally called “pulse outputs”, but it should be understood that they are actually solid state (transistor) switches and do not produce any voltage. The external device to which they are connected must provide wetting voltage with current limiting, and be able to respond to the contact closures.
Pulse outputs via the case connector option
2.8.1 Pulse output communication
EC 350 provides four pulse outputs, three (channels A, B, and C) normally-open Form A type, and one
(channel D) normally closed Form B type. The pulse outputs are typically used for connection to an AMR
(Automatic Meter Reader) device.
These outputs are electronic switches that operate like an isolated bidirectional switch. Channels A, B, and C (normally open type) can be configured as corrected volume or uncorrected volume. Channel C can alternatively be configured as a (normally open) alarm output. Channel D (normally-closed type) is only for alarm output use. All the pulse outputs of the EC 350, including the alarm pulse output, use opto-isolators for isolating the EC 350 circuitry from the devices receiving the pulses. Opto-isolators are devices that prevent unwanted current flow or possible damage from high voltage.
Alarm pulse outputs
An alarm pulse (on channel C or D) is generated when EC 350 enters an alarm condition. Use channel C
(NO or Normally Open) or channel D (NC or Normally Closed) depending on the AMR device accepting the alarm pulse. Use of channel D (NC) allows for a cut wire to be interpreted as an alarm condition to the
AMR device.
Volume pulse outputs
EC 350 provides three Form-A pulse outputs (channels A, B, and C) for volume output pulses.
Volume pulses can correspond to either uncorrected volume (as counted in item 2) or corrected volume
(as counted in item 0). The type of volume pulse (and whether the channel is enabled) is configured through items 93-95.
Honeywell
2016
35
2 EC 350 installation
2.8 General Wiring connections
The "weight" of each pulse (e.g. whether a pulse corresponds to 10 cubic feet or 1 cubic meter) is configured via items 1193-1195.
Note: In prior Mercury products the pulse weight was configured differently through items 93-95.
These are now read-only values provided for reference.
Pulse output timing is configurable via items 1014, 1015, and 1024. Various pulse ON and OFF times can be chosen. Default is a pulse ON time of 62.5 milliseconds and a pulse OFF time of at least 62.5 milliseconds, for a minimum pulse period of 125 milliseconds.

Event log records reference this user ID, to identify who made configuration changes.
Full use of multi-user features requires host software supporting the SS protocol command. For backwards compatibility with host software that only supports the older SN sign on command (which does not support multiple users), the user 0 passcode is required for sign on via the SN command. In that case all configuration changes made through an SN sign on are attributed to user 0 in the event log records.
The legacy item 196 (event log user ID) is not supported.

3.4 Metrological configuration mode
3.4 Metrological configuration mode
A special operational mode is available which may be useful when making configuration changes to an instrument already in service. Most changes would not require this, but if multiple changes are being made and there could be dependencies between those changes (in particular if the instrument would measure incorrectly if it received a volume pulse from the meter while the changes are still in progress – only partially completed). The mode is called Metrological Configuration Mode. In this mode, input volume pulses are queued but not processed, and Pressure and Temperature measurements are deferred.
Processing continues normally after you exit the mode, with the queued input volume pulses handled per the new configuration.
You enter and exit the mode either through the HMI (L2.9 and L3.11 MET CONFIG), or through Master-
Link by setting/clearing item 1239.
Note: The mode will also be exited automatically on an exit from HMI mode (either explicitly or by inactivity time-out) and likewise on a serial comm (MasterLink) disconnect from the instrument
(either explicit or by inactivity time-out). (It will exit the mode on either HMI or Serial exit, regardless of which was used to activate the mode.)

4 Key features
This chapter describes the key features of an EC 350 device.
4 Key features
4.1 Volume measurement
4.1 Volume measurement
EC 350 generally operates in the Corrector mode. In this mode, EC 350 receives and processes uncorrected volume, pressure, and temperature inputs to produce corrected volume information.
The following image illustrates a typical Corrector mode display.
1. Top line of LCD display indicates the totalized corrected volume value.
2. Second line indicates the corrected volume unit of measure (e.g. MCF).
3. Third line indicates the item’s name (e.g. CORVOL, which is corrected volume).
4. Bottom line shows active icons to indicate various system status information.
4.1.1 Corrected volume
EC 350 accurately measures and maintains the total uncorrected volume passing through the meter on which it is installed. In addition to the uncorrected volume, EC 350 also computes the corrected volume.
The corrected volume is computed by multiplying a total correction factor by the uncorrected volume input from the meter.
EC 350 maintains items called Hi-Res (High Resolution) volumes for indicating a fractional part of the corrected and uncorrected volumes that are not visible in the primary items (0 and 2).
Total Correction Factor = Temperature Factor X Pressure Factor X Auxiliary Factor (normally 1.0) X
Squared Supercompressibility Factor.
EC 350 supports a large range of units for measuring volume; some of them are as follows:
CF, CFx10, CFx100, CCF, CFx1000, MCF, CFx10000, m3x0.1, m3, m3x10, m3x100, and m3x1000.
You can independently configure corrected and uncorrected volume items.
Honeywell
2016
57
4 Key features
4.1 Volume measurement
4.1.2 Uncorrected volume
The gas flowing through rotary meter is measured by multiplying the input signals supplied by the two redundant volume sensors with the appropriate scaling factor (in item 114) for a particular rotary meter
(selected in item 432). Generally, 114 value is set automatically when the meter model is selected, but
114 can also be set manually for other meters models.
Currently, EC 350 supports over 140 meter models explicitly. Others can be supported with manual configuration.
4.1.3 Energy
In addition to the corrected and uncorrected volume, EC 350 also calculates the energy (in item 140) corresponding to the corrected volume, based on a fixed user-configurable conversion factor (item 142).
EC 350 supports a large range of units for measuring energy; some of them are as follows: Therms, Decatherms, Mega Joules, Giga Joules, Kilo Calories, and Kilo Watts.
Refer to the section “ Items reference ” for information about Energy (item 140), Energy units (item 141), and Gas energy value (item 142) .
4.1.4 Volume statistics
The EC 350 supports numerous gas volume statistical related items (Mins. Maxs, Peaks, Avgs) for Cor-
Vol, Unc-Vol, Flow rate, and Dial rate.
Refer to “Items reference” for information about the gas volume statistical Items.
4.1.5 Volume Input Modes
Refer to the “Items reference” for information about Input volume mode (item 433) and Rotary Integral mount (item 432).
4.1.5.1 UMB, Instrument Drive & Remote input
EC 350 supports gas volume measurement from UMB (Universal Mounting Bracket) and Instrument Drive interfaces. Select the meter model from the list provided from item 432. If the meter is not in the list, use item 433 to set selection: LF-UMB/Instrument Drive and configure meter index rate (item 98) and meter scaling (item 114) to match the application. Note that item 114 is typically set to value 1.000.
Note that two switch inputs are normally used in these applications to provide for switch input redundancy (one switch can backup the other).
Honeywell
2016
58
4 Key features
4.1 Volume measurement
4.1.5.2 Direct Rotary mount input
EC 350 supports gas volume measurement from directly mounted Rotary meters. Select the meter model from the list provided from item 432. In doing so, the EC 350 will automatically set items 114 to its proper value based on item 439. Note that item 98 is not used in Direct mount rotary and is assumed to be value 1.0 CF or 1.0 m3 depending on Volume units. Item 433 will also be set automatically to low resolution mode for rotary input. Low resolution rotary mode uses a pulse input divider to increase battery life while still proving adequate volume measurement resolution.
For direct-mount Rotary configurations only, EC 350 also supports an option called high resolution mode for obtaining a higher degree of gas volume measurement resolution. Use the Input volume mode (item
433) for selecting the high resolution mode option. In this mode, EC 350 measures the gas volume using a very low divider ratio for the input signals supplied by the two volume input sensors. In low resolution rotary mode, the divider ratio is much higher for making a sensible trade-off between the measurement resolution and the instrument battery life. High resolution mode is a useful test and verification tool for obtaining accurate volume measurement within a shorter period of time (less gas passing through the meter) – but consumes more battery power.
Note: EC350 battery life specifications are based on using the low resolution mode (not high resolution).
4.1.5.3 Bidirectional volume or Reverse flow
EC 350 supports another volume input option called Bidirectional volume input mode (Reverse flow) for obtaining gas volume measurement in applications where flow direction is desired. Two configuration options are possible for Bidirectional volume modes: Forward direction = Clockwise rotation, and Forward direction = Counter-clockwise direction. Use the Input volume mode (item 433) for selecting either of these two input mode options.
Listed here are the main volume items used for Bidirectional mode:
CorVol (item 000) – always counts up regardless of rotation direction
UncVol (item 002) – always counts up regardless of rotation direction
Forward CorVol (item 896) – counts up based solely on forward rotation direction per item 433 configuration
Forward UncVol (item 898) – counts up based solely on forward rotation direction per item 433 configuration
Reverse CorVol (item 902) – counts up based solely on reverse rotation direction per item 433 configuration
Honeywell
2016
59
4 Key features
4.1 Volume measurement
Reverse UncVol (item 906) – counts up based solely on reverse rotation direction per item 433 configuration
Net CorVol (item 900) – is the difference between Forward and Reverse Cor-Vol (item 896 – item
902)
Net UncVol (item 904) – is the difference between Forward and Reverse Cor-Vol (item 898 – item
906)
Four switch sensors are utilized in Bidirectional volume mode to allow for direction detection as well as redundancy protection. If one of the four switch sensors is not detected after completing a full revolution, the EC 350 will trigger a switch Alarm for that particular ‘missing’ switch sensor. For example: switch sensor input sequence of: 1-2-4-1-2… will trigger a Switch-3 sensor Alarm.
Attention: Three switch sensors are required to count volume input. If two switch sensors fail the EC
350 will trigger a switch Alarm for the second ‘missing’ switch sensor and will then stop counting

4.2.1 Gas Pressure
Gas pressure is measured on a time-based approach (every 30 seconds), as opposed to being based on volume input. With each 30 second measurement, the gas pressure correction factor is computed and high and low Pressure alarms are checked (regardless of flow rate conditions).
The EC 350 uses a high resolution analog to digital conversion process to produce a very accurate final reading.
Up to two Pressure Transducer can be used with the EC 350. The Pressure Transducer connected to the
P1 input is used for computing the Gas pressure correction factor (item 044). If a second Pressure transducer is connected at P2 input, this serves to monitor pressure but is not used for correction. Gas pressure measurement can be disabled for either transducer by use of items 1052 (P1 Enable) or 1053 (P2
Enable).

4.2.3 Supercompressibility
Gases actually behave in a manner slightly different from what the ideal gas laws indicate. This deviation depends on the molecular composition of the gas as well as the pressure and temperature. Natural gas, for instance, compresses by a greater amount than that computed by Boyle’s law and hence the term
“supercompressibility” is used for this deviation. It is small at very low pressure, but becomes substantial as the pressure increases.
4.2.3.1 Supercompressibility Factor
Gases actually behave in a manner slightly different from what the ideal gas laws indicate. This deviation depends on the molecular composition of the gas as well as the pressure and temperature. Natural gas, for instance, compresses by a greater amount than that computed by Boyle’s law and hence the term
“supercompressibility” is used for this deviation. It is small at very low pressure, but becomes substantial as the pressure increases. The EC 350 automatically applies the supercompressibility factor and therefore the equation for total volume correction that EC 350 applies to metered volume is expressed as:
Vb = Vm * Fp * Ft * (Fpv)²
Where:
Vb (item 0) = volume corrected to base conditions
Vm (item 2) = volume from the meter (at measured conditions)
Fp (item 44) = pressure factor
Ft (item 45) = temperature factor
Fpv (item 47) = supercompressibility factor per NX-19 or AGA-8 standard (derived for orifice meters)

4.3 Meter proving
4.3 Meter proving
The public utility commissions or various governmental regulations may require you to check the accuracy of the actual volume of gas flowing through a gas meter. Prover devices such as the Dresser Model 5
Prover and the Elster/American Meter SNAP Sonic Nozzle Prover are used for verifying the accuracy of the volume of gas flowing through a gas meter. Prover devices pass a known volume and temperature of gas through the meter being tested. They compare their own standard volume to the volume reported by
EC 350, which is mechanically connected to the rotary gas meter.
EC 350 uses switch closure pulse counts for providing volume data to the Prover device. The meter bodies and EC 350 are tested at various rates such as 10%, 50%, and 100% of rated capacity. You can connect EC 350 to a prover to test both uncorrected and temperature corrected volumes.
EC 350 has a special operating mode that makes meter proving process very easy and fast. This mode is called Pushbutton Proving . No special configuration settings are required to use the Pushbutton Proving feature of EC 350.

4.3.3 Starting Pushbutton proving
The basic operation of the Pushbutton Proving mode is as follows:
1. The prover dongle receives uncorrected or temperature corrected volume in the form of infrared light pulses from EC 350.
2. The prover dongle converts the received infrared light pulses to electronic switch closure pulses that can be handled directly by the supplied prover.
3. These electronic switch closure pulses are sent to the prover. Each electronic switch closure pulses represents either one (1), ten (10), or one hundred (100) cubic feet of gas volume, depending upon the model of the rotary meter.
4. When EC 350 is in Meter Proving mode, the volume pulse inputs from the meter are read at a much higher resolution than what is normally processed. This allows the most rapid proving cycle time for a given accuracy. Most proving runs can be accomplished within 60 seconds.
Attention: When EC 350 is in Pushbutton Proving mode, the IrDA Serial communications are disabled. Before you enter the Pushbutton Proving mode, ensure that the prover dongle is connected to EC 350.

For each log, you can select the percentage of memory allocated, if fewer than 5 logs are desired the percent of the unused ones must be set to zero.
Note: The sum total of memory allocated for all logs must be equal to 100%.
The smaller a log’s allocation, the less data it will be able to store. When the limit is reached, the oldest records will be overwritten with the newer ones. The consequence of a particular allocation setting is reflected in the number of Days worth of data as well as the Number of records that can be written before overwriting will occur.
Note: A log’s interval setting will impact Days, but not Numbers.
8. The Enable checkboxes may be used to suspend data collection for one or more logs. A log’s existing records will not be affected when the log is disabled. The fact that a log is disabled will be reflected in the Log Configuration window by the presence of a red ‘x’ at the top of that log’s item tree. In addition, the area for that log in the bar graphic will be grayed and marked as ‘Disabled’
9. Finally, click Send to Instrument to push the log configuration to the EC 350 Device. A few seconds will be required for the transfer. A window should appear indicating ‘Successfully Configured’.

4.5.2 Reading Audit Trail from the EC 350
Once audit trail logging is configured and some amount of data has been collected, it may be transferred to the host. The process can be initiated from the Transfer menu or icon
Data window.
using the Read Audit Trail
You must specify the number of logs to read and the amount of data to transfer. All configured and enabled logs can be checked in the Log Selection frame. If a log is not configured it cannot be checked.
The amount of data is specified by date/time ranges. The simplest option is Since Last Download. The host will examine its database for the most recent record for each log for this instrument and construct a command to the EC 350 for all data it has collected since then. Using this option each time will ensure that the host database contains a complete set of audit trail records for each log in each instrument.
There are three other options if a specific data range of data is desired.
Note: Reading of audit trail records does not remove them from EC 350’s memory. They can be read any number of times until they are overwritten, as explained above.
Once Masterlink finishes reading all data for all logs the user is given the chance to view all the downloaded records. This is a useful practice to ensure that the transfer succeeded and that all the expected records were read.

4.5 Logging
4.5.4 Log record integrity verification
Audit Trail and Event Log records have a CRC value associated with them to allow verification that they have not been corrupted or modified. CRCs of log records that have been uploaded to a computer using
MasterLinkSQL can be compared to log record CRCs displayed on the HMI. Since records cannot be modified in the device, the CRC values shown through the HMI are always correct and so if the CRC values shown in MasterLinkSQL do not match, then the log record on the computer may have been corrupted or otherwise modified.
First view the log records uploaded with MasterLinkSQL. Audit Trail record CRCs can be viewed through the Audit Trail CSD Conversion feature in the File menu. That outputs a Comma Separated Value file that includes the record CRC as transmitted by the device and also as computed by MasterLinkSQL of the record as stored in the MasterLinkSQL database. Event Log record CRCs can be viewed through the Event
Log Report. In the report configuration, select the option to view the CRC values.
To view records in the HMI, select the corresponding menu item, select the desired log (Audit Trail 1 through 5, or Event Log), enter a Sequence Number for a record (as seen in MasterLinkSQL). The corresponding record will be shown with the sequence number, the CRC value (in decimal), and the date and time of the record. (Other record values cannot be displayed via the HMI.
Compare the CRC value on the device display with the one in the Audit Trail CSD file or the Event Log report. The UP and DOWN arrow keys can be used to show the previous or next record.

4.6 Battery Life/ Usage Tracking
4.6 Battery Life/ Usage Tracking
Alkaline Battery– Item 48 tracks the Battery voltage and Item 49 is the configurable Low Limit for tripping a low Battery Alarm condition. Item 50 is the configurable Low Limit for putting the
EC 350 in to a low Battery ‘shutdown’ condition – ending most of its operations to greatly conserve the battery power.
Lithium Battery - Items 1001 and 1002 indicate the remaining months and percentage of the
Lithium Battery pack based on estimated ‘usage cycles’. Item 59 tracks the battery usage cycles
– but only for a limited amount (mainly for testing purposes). Item 60 is the configurable Low
Limit for tripping a low Battery Alarm condition based on too high of battery usage cycles. Item
59 value represents micro-Amp-seconds usage of the Battery.
Battery / External Supply Alarms – RBX Mode
Non-RBX Mode (Item 165 = 0)– No automatic clearing of alarm condition. User must clear
(acknowledge) the alarm condition of Item 99 or 796 before a new Alarm Log entry or timestamp update can be made for any subsequent Low Voltage Alarm conditions.
RBX Mode (Item 165 = 1)- RBX Mode enabled will allow for automatic clearing of a Low Voltage alarm condition of Item 99 or 796 if the measured voltage reaches a value greater than 0.60
VDC above the Low Limit value in Item 49 or 795 respectively (Battery or External Voltage).

5.1.2 Human Machine Interface (HMI)
It provides access to the information about EC 350. You can configure the information using the integral
LCD panel and keypad. HMI keypad mode can be classified into the following four sub-levels.
- It is the scroll list mode where the customer-configured list of items appear on the display. No passkey is required to access this mode. After the keypad is active, use the UP arrow and DOWN arrow to scroll through the items in this mode. The items in this mode are read-only.
Level 1 read only mode - It is used for viewing the instrument settings and live parameters. You
do not require any passkey to access this mode. In this mode, the instrument functions are categorized into 11 submenus. By scrolling through the 11 submenus, you can view over 60 factory-defined instrument parameters. The items in this mode are read-only.
Level 2 mode - It is used for accessing the less sensitive parameters and configuration options of EC 350. This mode provides six submenus. You can view and configure the items in this mode by scrolling through the six submenus. A passkey is required to access this mode.
Level 3 mode - It is used for accessing all the parameters, configuration, and functions of EC
350. This mode provides nine submenus. A passkey is required to access this mode.

5.1 Getting started with the keypad digit security passcode to enter level 2 or level 3 mode. You can enter any value for the event log user ID. If the unit is configured to log events in an event log, the user ID identifies the user who made the changes in the event log.
For firmware version 1.0068 and later, of the 7 digits entered, the first two are the user id and the
last five are the passcode. By default only user 02 is permitted access to Level 2. The default passcode is 20000, so the value entered would be 0220000. Other users can be granted access to level 2 menus, but a user can only access level 2 if they are not granted access to level 3. (A single user can access level 2, level 3, or neither, but cannot access both level 2 and level 3. Level 2 functionality is a subset of level 3 functionality.)
4. To enter passcode, press the UP arrow or the DOWN arrow at the current position to change the displayed digit to the required numeral.
5. For example, press the UP arrow twice at the current position, the value 0000000 changes to
2000000.
6. Press the RIGHT arrow to move one position to the right. Using the UP arrow or the DOWN arrow change the displayed digit to the required numeral.
7. For example, press the RIGHT arrow until you reach the sixth digit. At the sixth digit press the UP arrow twice. The value 2000000 changes to 2000020.
8. Repeat this step until you enter the passcode of the instrument.
9. To accept changes after entering the last digit (all seven digits of passcode), press the RIGHT arrow.
Attention: You can also press OK for entering the passkey value.
The OK key enters the displayed digit at the current position and advances to the next position.
If the log in was successful, the display indicates that you are in level 2 mode. If the user ID or passcode were invalid, you will be returned to the main level 1 menu.

5.3.1 About MasterLinkSQL software
MasterLinkSQL is a communication software package that enables interaction with EC 350. Using
MasterLinkSQL you can:
Configure EC 350 to meet particular needs.
Calibrate EC 350.
Read the collected data such as volumes, pressures, temperature, and alarms.
Generate reports for the collected data.
Provide computer to instrument communication. Computer to instrument communication can be through the IrDA (infrared) port on the front panel, an optional direct serial link (RS-232/485), modem (CNI2 for cellular or Messenger for land line).
5.3.2 Connecting the IrDA communication USB dongle to the computer
To connect the IrDA communication USB dongle to the computer, insert the IrDA USB dongle in the USB port of the computer.
If the IrDA USB dongle is connected properly, a small LED on the dongle flashes intermittently, which indicates that the computer can communicate with the IrDA USB dongle. Using the MasterLinkSQL communications configuration menu, confirm that the IrDA interface has been configured properly.
5.3.3 Connecting the IrDA communication USB dongle to EC 350
To connect the IrDA communication USB dongle to EC 350
1. Insert the dongle into the magnetic pipe boot. Ensure that the cable passes through the hook provided in the magnetic pipe boot to prevent the dongle from displacing.
2. Place the boot on EC 350. Ensure that the leg of the boot is above the eyebrow.
The following image illustrates the IrDA communication USB dongle connected to EC 350.

5.3.4 Signing on to the EC 350
Open MasterLinkSQL and fill in any fields in the opening screen. You can connect to a specific site through the Site List (this is required for remote connections through a modem), or, for local connections you can simply request some operation and MasterLinkSQL will initiate the connection automatically.
If requested, enter a user ID and passcode. Your organization should provide you with this information.
User ID can be any value from 0 to 99. By default only users 0 through 3 are activated. Passcode can be any value 0 to 99999. Given below are the default passcodes for users 0 to 3.
Table 1.
User Default passcode
User 0 and 1 33333
User 2 20000
User 3 30000
Default users 2 and 3 are primarily intended for HMI access (levels 2 and 3 respectively) but serial access with MasterLinkSQL through those users is also possible with those passcodes.
5.3.5 Updating EC 350 firmware
EC 350 is provided with a built-in firmware loader that allows new versions of firmware to be installed easily. Firmware can be upgraded using the Firmware Upgrader option available in the MasterLinkSQL software. When you select this option, the MasterLinkSQL software works with the built-in loader of EC
350 and provides a very robust system for upgrading the EC 350 firmware.
The firmware upgrade is performed through the IrDA serial interface that is used by the MasterLinkSQL software. The IrDA serial interface provides an electrically isolated interface and requires no additional hardware or software beyond what is already needed to utilize the MasterLinkSQL software. (Firmware upgrades can also be performed over the RS-232 port but not the RS-485 port.)

High and Low Intervals; however, you are not required to use both. Let's assume you have a customer that is "interruptible" (curtailed). Of course, you cannot completely shut the gas off because the customer has a large number of pilot lights that must remain operative; therefore, a very small consumption is expected. You could set up the following tri-level central interval high checking scheme:
Central Interval 1 High - Set this to the lowest level of severity. If consumption rises above this level, monitor this customer more closely.
Central Interval 2 High - Set this to the middle level of severity. If consumption rises above this level, call the customer.

6 Remote Communications
This chapter describes the different communication mechanisms featured in a EC 350 device.
6 Remote Communications
6.1 Use of RS232/ 485
6.1 Use of RS232/ 485
Application
EC 350 is capable of communicating with a number of types of external devices, such as cellular or landline modems, and RTUs. EC 350 supports the following protocols: MI Protocol, Modbus RTU, Modbus
ASCII. The description of those protocols is beyond the scope of this manual, although a basic discussion of Modbus operation is presented later in this chapter. This section describes the physical connections and instrument configuration parameters that are required.
Connections
Wiring connections are made to TB4, see below:
For RS-232, only 3-wire communications is supported: pin 1 TXD (Transmit Data), pin 2 RXD (Receive
Data), and pin 5 GND (Ground). (The TB4 RTS/CTS connections are not used.) TXD and RXD are labelled as a DTE device (EC 350 transmits on TXD).
For RS-485, use TB4 pin 1 (TXD) as line A, pin 2 (RXD) as line B, and pin 5 (GND) as Ground.
The RS-232 and RS-485 standard specifications should be consulted for the proper wire type, maximum cable length, etc.
Jumpers
In addition to wiring, jumpers on JP1 and JP2 must be properly positioned. For RS-232, both jumpers must be set to B and C as shown in the picture above. They must be placed on A and B for RS-485.

6.1 Use of RS232/ 485
Configuration Parameters
EC 350 items in the ‘Communications’ group in MasterLink may need to be modified to accommodate a particular external device.
Items 170 and 172 are primarily associated with the behavior of MI Protocol. These should normally left as default (shown here). The remainder will vary depending on the external devices. See also Modbus section below for settings relevant to the Modbus protocol.

6.2 Call in and call out
6.2 Call in and call out
Call out
6.2.1 Call in
EC 350 has the capability to initiate a modem to modem telephone call. This is called call in and can happen under two circumstances.
Alarm Call-In
Scheduled Call-In.
6.2.1.1 Call in
When connected to either a cellular or landline modem the EC 350 can be configured to autonomously dial and connect to a host computer. It can do this according to a preset schedule or in the event of an alarm condition. Previous Mercury Instruments products have incorporated similar features, but the EC
350 is unique in its support of four phone numbers (or IP addresses); two for scheduled calls and two for alarms. This provides the ability to communicate with four different hosts. In turn, this feature leads to some differences in the retry algorithm. Call in configuration items are:
Honeywell
2016
205
6 Remote Communications
6.2 Call in and call out
Modem items are shared between the scheduled and alarm call in features. If the modem requires an initialization string it must be set into item 491 along with an Init Delay (Item 821). The initialization delay is applied so that the modem, having just been powered up, has a chance to stabilize before being sent the initialization string. A dial prefix must be configured in item 492 and a hangup string in 494. The Dialing Delay will take place following the issuance of the initialization string. Call in sequence, Trigger Type and retry parameters are also shared between scheduled and alarm calls. Those will be discussed later.
6.2.1.2 Scheduled Call In
The EC 350 can initiate a call at a preset time. The time may have been manually specified, but on an ongoing basis the host(s) is responsible for the schedule. At the end of each call the host is must set item values that determine when the next call is to take place. That time will always be contained in items
334 and 335. Items 338 and 337 indicate the result of the latest call ( or call attempt ). If only one host exists, its phone number is set in item 339. If a second host exists, its number is set in item 1030. To enable scheduled call in, at least phone number must be configured and item 333 must be set to either
Alarm and Scheduled Call In or Scheduled Call In Only.
6.2.1.3 Alarm Call In
If alarm call in is configured and enabled, a call will be initiated whenever a new alarm occurs or, if in
RBX mode, an alarm condition clears. This requires a phone number in item 493 ( and optionally in 785 ) and item 333 must be set to either Alarm and Scheduled Call In or Alarm Call In Only.
6.2.1.4 Management of Multiple Phone Numbers
If multiple phone numbers are configured, item 1230 determines ( along with the retry strategy ) when and if the second number is called. The setting will affect the behavior of scheduled and alarm calls identically.
Call In Sequence = BOTH:
When a call is triggered, the EC 350 will dial the first number first. Regardless of whether that call succeeds or fails, the second number will also be called. The BOTH algorithm ensures that both hosts will (eventually) receive notification. If a call to a host fails, it will be retried as many times as necessary until the call succeeds. The two numbers are independent – whatever happens on phone number 1 will not affect phone number 2 and vice-versa.
Call In Sequence = PRIORITY:
This algorithm ensures that someone will (eventually) receive notification, and it will be whoever succeeds first. As soon as either one succeeds the process is complete. Some possible sequences are:
1 S. Done.
Honeywell
2016
206
6 Remote Communications
6.2 Call in and call out
1 F, 2 S. Done.
1 F, 2 F, 1 S. Done.
1 F, 2 F, 1 F, 2 S. Done.
(where 1 and 2 represent the first and second phone numbers, S denotes success, F denotes failure
)
6.2.1.5 Retry Timing
Not all call failures are resolved with ‘retries’. ‘Retries’ is defined as the termination of the current attempt and the scheduling of another attempt some minutes or hours hence. In some cases the EC 350 may try to resolve the failure immediately. If, for instance, an initialization string is sent to the modem but no positive response is received within several seconds, it will simply send it again. If several initialization attempts fail, then it will be deemed hopeless (for now) and a future retry will be scheduled. The same is true if a dial string goes unanswered. But after a certain point another immediate attempt would be futile and a future retry is scheduled.
There are three retry timing parameters – two delays ( A and B ) and a counter. For any given trigger
(schedule or alarm ) the first retry will be scheduled to take place Retry A minutes in the future. Retry A will be used for subsequent retries until Modem Retry A count is exhausted. The next ( and subsequent ) failures will be scheduled at intervals of Retry B minutes. Once the call finally succeeds ( or another trigger occurs ) the counter, and thus the retry sequence, will be reset.
6.2.1.6 LCD indications
When a call is triggered, the information on the 2nd and 3rd lines of the LCD will be replaced with messages indicating the progression of the call, such as ‘INIT MODEM’, ‘DIALING #’, ‘DIAL FAILED’,
‘CONNECTED’, ‘WAIT FOR CONN RESPONSE’, ‘CONNECTED’, ‘WAITING +-+CLRALMS’, and ‘HOST SYSTEM
CONNECTED’.
6.2.1.7 Forcing a Test Call
During initial commissioning as well as subsequent troubleshooting, it is useful to be able to manually evoke a call. This can be done by writing the proper value to item 264: 20139796 will trigger a scheduled call; 20139813 will force an alarm call. The same can be done using the HMI. See the HMI section for details.
Honeywell

6 Remote Communications
6.2 Call in and call out
6.2.2 Call out
The Call Out window (COW) allows EC 350 to accept remote communications during one or two blocks of time during the day.
When used with a CNI2 cellular modem, the CNI2 will be set to “server mode” during the call out window
(s) so it can accept calls from a host system during those times. The CNI2 consumes more power in server mode, regardless of whether communication occurs.
EC 350 can also be kept “awake” during the call out window(s) such that even the initial characters of a communication session are accepted. Otherwise, the initial characters “wake up” the EC 350. The MI Protocol includes such wake up characters in its protocol so that this feature is not required for MI Protocol communication. But the Modbus protocol includes no wake-up characters, so this feature can be used so that the EC 350 processes the first Modbus packet. Without it, the first packet is not processed and the
Modbus host system must send a “retry” packet. More power is consumed during the call out window in this mode, regardless of whether communication occurs or not. To use this mode, in addition to specifying a call out window, set item 1236 (Port Active During COW) to enabled. This mode consumes more battery power but reduces retries on Modbus activity.
There are items for specifying the start and stop times for two call out windows. Set the start and stop times equal to disable a call out window. (Do so for both if they have no call out window.) Times are specified in 24-hour format. The maximum value is “23 59 00”. Seconds other than “00” are ignored. The resolution for the times is one minute. No single call out window can be longer than 18 hours, but greater than 18 hours can be achieved by scheduling two call out windows “back to back” (e.g. 00 00 00 - 12 00
00, 12 00 00 - 23 59 00 would effectively give you a call out window for the entire day except one minute before midnight).
The modem will stay active until a stop time is reached or when the current call (if after the stop time) has ended. EC 350 goes back to sleep if there is no call out.

6.3 Modbus Communication
6.3 Modbus Communication
Modbus is a common industrial communication protocol. The EC 350 supports the Modbus protocol (as a slave device) on the TB4 RS-232/485 port as well as the front panel IrDA port. Through the RS-232/485 port it can also be used with modems including Messenger, CNI2, and Cloud Link. Function codes 01, 02,
03, 04, 05, 06, 15 and 16 are supported, in both RTU and ASCII modes.
The Modbus protocol standard defines the format of the data and the techniques used to control the flow of data. It supports one master device and up to 247 slave devices on one bus (although a maximum of
32 slave devices are permitted on an RS-485 network, due to physical layer limitations). The master always initiates a communication exchange. Each slave on a Modbus network has its own unique address (1...247) so that it can be addressed independently from other slaves. This address is sent by the master as part of every message. All slaves on the network see the message, but only the slave with the matching address will respond to the message. A message sent to a slave from the master is called a request, the answer sent back to the master is called a response. Request and response messages are also called packets or frames. The master can also broadcast a message to all slave devices, using a slave address of 0. In that case there is no response.
Modbus configuration items are found in the ‘Modbus Protocol’ and ‘Modbus Map Registers’ function groups of MasterLink:
If the external device communicates via Modbus protocol, item 985 must be set to 1. Item 994 will need to be set to the proper Modbus variation, either RTU or ASCII. The correct setting for all of these items will be determined by the external device used.
Modbus registers can be ‘mapped’ to items in the EC 350 via the items in the following group. For example, pressure can be mapped to register 7003 by enabling Float mapping in item 935 and setting item 943 to ‘8’.

7.6 Replacing the Battery Pack
7.6 Replacing the Battery Pack
If your EC 350 displays REPLACE BATTERY, it indicates that EC 350 has gone into a power conservation mode due to low battery voltage.
Replacing the battery in a hazardous DIV-1/ZONE-0 environment
A special operating mode is provided to allow changing of a battery pack in a hazardous location. (If the location is known to be non-hazardous, for example, if the location has been tested for the presence of gas and it has been determined that gas is not present, this section can be skipped. Go to the Replacing the battery in a non-hazardous environment section). The special operating mode puts the corrector in a standby condition in which volume continues to be accumulated and event logging and alarms are still active, but all other functions are stopped to ensure very low power drain. This allows a low power battery (40-6054) to be plugged in while the main battery pack is changed, and then removed after the new battery is plugged in.

To replace the battery in a hazardous DIV-1/ZONE-0 environment, perform the following steps:
1. Enter HMI and set the EC 350 to Battery Change mode. You can use the L2.11 or L3.13 HMI menus.
2. The BATT CHNG message is displayed on the LCD screen. Press the Enter key.
3. Select Yes and press Enter. The unit is now ready for a battery change out. CHNG BATT THEN ESC is dispalyed on the LCD screen.
4. Plug the Swapout Battery (part no. 40-6054) into the open connector on the battery Y cable.
5. Unplug the old battery.
6. Plug in the fresh battery where the old battery was plugged in.
7. Remove the Swapout Battery.
8. Press the ESCkey twice to exit the battery change mode. When the ESC key is pressed, all the battery life items are automatically set to 100% new values and the battery usage cycle is set to zero.

7.7 Low battery/ External Power shutdown mode
7.7 Low battery/ External Power shutdown mode
EC 350 automatically enters a low battery shutdown mode when the battery voltage measurement falls below the value of Item 50 (Battery Shutdown Limit) for three (3) consecutive times.
Note: Item 50 Shutdown Limit applies to both Battery Voltage and External Supply Voltages.
While in low power shutdown mode, the LCD displays the following (except if user enters HMI mode):
_ _ _ _ _ _ _ _ _ _
“REPLACE”
“BATTERY”
To exit Low Power Shutdown, the Battery voltage must be above the Item 50 limit value and the user must enter HMI mode. User enters HMI and menus down arrow to the screen showing: SHUTDOWN -
HMI menus: L2.10 or L3.12. Next, the User presses Enter key and display will show: ‘ENTER MODE’ as first selection. Arrow down to ‘EXIT MODE’ selection. User again presses the Enter key to confirm – the unit leave (exit) Shutdown/Shelf mode. When the User exits the HMI menus – the LCD will then return to normal default screen.
