Mounting & Installation

Equipment Required

• Lap Top Computer (Using Win XP, Win Vista, Win 7 or Win 8) running HVC Host.

• Communications Cable (HPN 77R61-0070)

• Test Gauge, Dead Weight Tester or Accurate Pressure gauge

• Temperature Reference (If equipped with gas temperature probe)

• HVC Mounting Kit (gasket, wrench)

• Mechanics Tool Kit

Matching the HVC to the Meter Rotation

The HVC is equipped with a “Falling magnet/ reed switch” Mechanical Index Assembly. The HVC

is suitable for direct mounting on most diaphragm, rotary or mechanical turbine meters including, among

others, Rockwell, Equimeter, Roots, Dresser, Romet or American with instrument drives.

When directly mounted to a meter, the user should ensure that the mechanical index rotation of the HVC

matches the rotation of the meter. Unless otherwise specified, the HVC will be shipped suitable for

clockwise (CW) rotating meters. The proper rotation can be confirmed by spinning the drive dog on the

bottom of the instrument in the direction required by the meter. If the mechanical counter odometer

turns in the wrong direction, change rotation by engaging the optional brass gear on the horizontal shaft

on the mechanical index.

When configuring the HVC using HVC Host, the “UnCor Vol Input” will be configured by default to

“Digital Input”. This will grey out the: “Clockwise” selection and will set the “Meter Speed” to “Fast”

regardless of actual meter rotation as the falling magnet/ reed switch mechanical index is in use. If the

optional Optical Index is used, the “UnCor Vol Input” will be configured to “Opto Input” which will

enable the direction and speed selections.

Meter Mounting

The standard HVC will fit most any mechanical meter instrument drive. Use gasket (provided) between

the HVC and meter base. Mount on to top of the meter while insuring that the HVC drive pin engages

properly with the meter drive. Verify meter rotation. Secure the HVC with bolts (not supplied with

mounting kit) to the meter base.

A “Large Mounting kit” (77R61-9580) can be supplied as an option. This kit consists of mounting

hardware, test plug, isolation valve, miscellaneous fittings and 1/8” tubing to allow connection of pressure

to the HVC.

NOTE: A rotatable base plate allows for user desired orientation of the instrument. The base plate is

removed using a 5/32 hex wrench to remove four bolts. The INSTRUMENT may then be re-installed

with a different orientation. The base plate MUST maintain its original position and be positioned toward

the front of the meter indicated by a drill spot on the top of the base plate. CAUTION: TO PREVENT

DAMAGE TO THE METER DO NOT CHANGE ORIENTATION OF THE BASE PLATE ON THE

METER. ONLY CHANGE ORIENTATION OF THE INSTRUMENT.

Pressure Connection

Connect the pressure (or gas) supply to the 1/4” NPT female connector located on the back of the HVC

housing. After piping is complete, check all connections to ensure that no leaks are present. Note: For

ease and isolation of testing, the HVC large mounting kit is recommended. This kit will assist in future

calibrations and inspection while the unit is in service.

9

Temperature Probe Installation

If equipped, the standard 6’ long temperature probe (6” x 1/4” OD) should be installed into the

appropriately sized thermowell filled with a thermo conductive medium such as glycol or alcohol. Insert

the temperature probe into the thermowell through the standard 1/4” inch NPT male fitting (provided)

until the tip of the probe reaches the bottom of the well. Secure excess armor cable length of the probe.

It may be necessary to isolate the pressure and temperature connections to the pipeline, so as not to disturb

the cathodic protection system.

Electrical installation

NOTE: Refer to drawing MTM-308-1 for field wiring requirements for external power and modem

connections to maintain intrinsic safety.

The HVC unit must be earth grounded to maintain safe operation and warranty.

The ground stud of the HVC (located on the bottom left of the instrument) must be connected to a suitable

known external earth ground (usually a dedicated ground rod and NOT AC ground). All of the major

components in the HVC are bonded together and connected internally to this ground stud. It is required

that grounding be performed, especially when an external modem and/or external power supply (which

requires a dedicated ground rod in close proximity to the safe area) is used. All cabling connecting to the

HVC must be shielded with all shields tied to case ground.

For multiple device interconnections (modems, power supplies etc.) the ground stud of the HVC must be

tied directly to this same (safe area) ground rod rather than having a separate ground rod of its own. It

may be necessary to isolate the portion of the pipe that the HVC is mounted to (with insulating flanges)

so as not to disturb the cathodic protection system.

The American Gas Association recommends grounding all electronic field devices to a driven ground rod.

This will help protect the device from transients including lightning and power surges on the pipeline.

To reduce the possibility of “secondary” lightning strike damage (damage caused by static electricity

fields in the immediate area), the above precautions are required. However, these precautions cannot

prevent damage to an instrument that receives a “direct” lightning strike.

Battery Pack and Back-up Batteries

The HVC units utilize (1) 1.5-volt, encapsulated “D” cell alkaline battery as its primary power source. The

pack supplied with the HVC consists of an alkaline dry cell and a protection circuit.

Part Number: I.S. Battery pack (Black): 77R91-1037

Part Number: Non-I.S. Battery pack (Blue or Yellow): 77R91-1091

NOTE: This battery is not rechargeable.

HVC units are shipped from the factory powered and ready to install in the field (unless otherwise

specified).

The HVC incorporates an on board uninterruptible power supply. This consists of one factory installed

“AA” lithium cell (BT1) rated at 3.6 volts. This cell is easily replaced in the field.

Part Number: 77R65-8001

The HVC incorporates an on board battery (CR2032) for backup of the profiler log. This consists of a

replaceable button style lithium battery (BT2) located on the component side of the PCB.

Part Number: 77R65-8002

10

Normal Main battery voltage should be displayed between the ranges of 1.5 to 1.7 volts for a new battery,

and when the primary power drops below .8 volts, the unit will switch to lithium backup. Under normal

conditions, the main battery pack should last up to four years and the lithium backup battery should last

up to 1 year without power from the main battery. Lithium standby life is 7-10 years.

Note: If all three batteries lose power, the data that is stored in non- volatile memory will not be lost. This

includes Calibration, Poly (transducer) and configuration data.

Caution: When the communication cable is connected to the instrument, higher than normal battery current

is consumed. Because of this, it’s recommended to limit the time connected to the instrument.

Caution: The maximum voltage allowed on the “Main battery” input is 2 volts DC. Only use the 1.5

volt battery pack supplied by Heath. If this voltage is exceeded, a protection fuse may blow and the

warranty will be void.

Caution: To maintain the Intrinsic Safe rating, use only proper replacement batteries: main battery pack

HPN 77R91-1037, Lithium backup battery, HPN 77R65-8001, and coin battery, HPN 77R65-8002.

Contact Heath Consultants for replacement batteries and main battery packs. Refer to Annual Checks on

page 37 for replacement procedure.

External Power

The HVC can be connected to an external power source (6- 15VDC). External Power is recommended

when using modems which are externally powered.

Contact Heath Consultants for this harness.

Pulse Outputs

Form “A” type. The HVC is equipped to provide pulse outputs representative of uncorrected and corrected volume. There

are two pulse channels available and are designated “A” and “B”. The pulse outputs are two-wire open

drain. Pulser A is designated for uncorrected pulse out. Pulser B is designated for corrected pulse out.

Contact Heath Consultants for this harness.

Specifications for Pulse Outputs Pulse output electrical specification is as follows: Open drain, requires external 1 to 30 volts maximum,

25 mA maximum, and 1 K minimum load resistance. Each pulse has a standard fixed pulse width of 62.5

milliseconds with a duty cycle of 50% (62.5 ms on and 62.5 ms off). An optional 1000 milliseconds (1

sec) pulse width is also available.

Because of the wide variety of applications requiring connection to the pulse output channels,

consideration should be given to the site electrical classification as to the use of intrinsic safety barriers.

Alarms

To configure the alarms, go to Configure column/” Alarms and Nominations”:

Set the Mode to “Manual” to activate an alarm that must be reset by the HVC Host software or the scroll

button. Set to “Manual Call” to activate “Call out upon Alarm” (must have a modem connected).

Set the “Trip” value that the alarm will activate on.

Contract Management values are in Cubic Feet.

Current Readings are displayed for reference when setting the alarm values.

All alarms can be reset manually by holding the scroll button closed for more than 4 seconds. They can

also be configured and reset by using the HVC Host. An active alarm will be indicated by a lower row of

dots on the LCD display. The HVC LCD will display the active alarm by scrolling to the alarm screen.

11

External Modem

The HVC is equipped with two RS232 communication ports. The Direct Port is dedicated to local direct

PC communication at 19200 baud using the HVC com cable. The Remote Port is used for connecting a

modem. Remote baud rates available are 300, 1200, 2400 (default), 4800, 9600 and 19200. When

configuring for a remote modem, the “Remote Modem Baud Rate” in the unit must match the baud rate of

the field modem being used. Connect the RX, TX & GND from the modem to the instrument on J13. A wiring

harness is required for this connection.

Note: If the external modem powers down to save power, the CTS wire is required to wake the modem prior to

“dialing out upon alarm”- if this feature is enabled. Otherwise the CTS wire isn’t required for inbound

communication.

Caution: When connecting the HVC to an external modem, it is recommended to connect external power

to the instrument due to higher current demand from the RS232.

Internal Modem

The HVC may be equipped with an internal modem and phone line surge suppressor. The internal modem is a 2400-baud

modem. The modem is pre-configured and pre-wired from the factory, ready for remote communication. If the HVC is

equipped with the phone line suppressor, it will be connected directly into the modem’s RJ-11 connector. A 12-volt battery

pack (8 “AA” batteries) is supplied, but not connected when shipped. The user must connect prior to remote

communication. Assuming one two- minute call per day, every day, the battery should provide approximately 2 years of

service. The optional phone line surge suppressor will sacrifice itself to protect the equipment in the event of a destructive power

surge on the phone line.

To connect a phone line to the modem, insert the phone cable through the black wire gland on back of the case (see Figure

1). The cable must be terminated with a RJ-11 connector. Plug into surge protector if provided; otherwise, plug directly to

the modem.

CAUTION: The HVC must be connected to earth ground to allow the surge suppressor to operate properly.

CAUTION: Internal modem option is not currently certified for use in hazardous environments. An external modem

should be used when necessary. Refer to drawing MTM-308-1 for field wiring requirements on external power and modem

connections to maintain intrinsic safety.

HVC HOST Operating Software

HVC Host is the companion software interface to the HVC instrument. The application program provides

for configuration, calibration, local and remote communication, interrogation, data collection and data

processing.

The Auto Download feature allows automatically polling any or all the instruments (on remote

communications- modems or TC/IP) from a “Master Directory” list. This “Auto Download” feature is

included in the HVC Host and is supplied on CD ROM media. The self expanding executable “setup” file

will guide the user through the installation process.

This install will work in Windows operating systems for Win Vista, Win XP, Win 7&8. NOTE: This install must be on each workstation in a network. The data can be sent to a network drive

and be shared by other workstations that have HVC Host installed. Remember to change the “Data Paths”

of each workstation to use the same network drive and directory. DO NOT INSTALL THIS SOFTWARE

DIRECTLY ONTO THE NETWORK SERVER DRIVE.

Software Installation

To install, locate the file “HVC Host Setup 4.03.exe”. Double-click the file to install. Follow the

instructions to complete the installation process. After the software is installed, you may need to configure

the com port to directly connect to the instrument. Com 1 is very common for direct communications;

however, many newer computers are not equipped with a 9-pin connector for direct connect with the

standard com cable. A “USB to Serial adapter” may be required. Follow the instructions included with the

USB to serial adapter. After the adapter is installed and connected to the PC, go to “Start”/ Control Panel/

System/ Hardware/ Device Manager/ “Ports” (click the “+” to the left of “ports”) Look for “USB to Serial

Bridge (com xx)” Enter this port number in the HVC Host (Host Setup/ Configure Host)/ “Direct”. Any

port from 1-255 can be chosen. Note: Only the available ports will be listed in HVC Host/ Host setup

“Name” dropdown. NOTE: HVC Host requires a screen setting of at least 800 X 600.

Quick Start Guide Note: Click “F1” key for help on any item

1. Install the HVC Host software from the CD software disk provided.

2. Setup “Host Setup” (Com 1, 19200, Direct, is most common). If your com port is different than com 1 (or you

are using a USB to serial adapter, find out the port number and select it in HVC Host/ Host Setup). (More info

on com port setup on page 13, 19-20). Make sure to use the same USB port every time to keep the same port

number.

3. Make any other changes to the Host Setup. Click OK.

4. Connect the communication cable from the PC to the back of the instrument.

5. Using the HVC Host software, select “Security” column/ “Logon Instrument”. The status bar will show

“Logged on” in green. Note: “Instrument Response Failed” will be displayed if the com port isn’t configured

correctly.

6. To configure the HVC for field use, select “Configure” column/ “Configure 1”. Select appropriate

configurations. (If no changes are made, the default values will be used). Click “OK”. (More configuration

details on pages 19-21).

7. To configure the site information: Go to “Configure” column/ “Configure 2” select "Configure/ Site Info".

Enter the site address/ Modem baud rate (If modem is equipped) & setup pulse outputs (If pulse outputs are

needed).

8. To set up the alarms: Select “Configure” column/ “Alarms and Nominations”. Select the alarm reset “Mode”

(Ignore, Manual or Manual Call) and the “trip point” of the alarm. Click “OK”

9. To reset the HVC Clock to match your computer: Select “Configure” column/ Go to “Set Real Time clock”.

Press the [Enter] key (Make sure the time & date is correct in the PC).

10. The default password configuration uses “logon” for full access and “readonly” for Read Only access. Since

the Host setup has “logon” as the default, no passwords will be prompted and full access will be granted. To

set up a “special” password for access to the HVC: Go to “Configure” column/ select “Set Access control”,

change the default password for “Full Access” or “Read-only”. The “Host Setup” has a “Default Password”.

If it matches the “Full Access” password, Full access is given- without needing to enter a password. This

“Passive Security” is best if all instruments have the same passwords and the technicians have the same

“Special” password in their computers “Host Setup”.

11. Reset the “Profiler”. “Configure” column/ “Reset Profiler”/ at Warning screen select “Yes”. This resets the

recording of hourly Volumes, pressure and Gas Temp.

12. It is recommended to “Backup” the Configuration, Calibration, Transducer Coefficients & Site info. This

same info can be sent to the same instrument (for example if the main pcboard was replaced) or the

“Configuration” can be sent to another HVC to allow consistent configuration for each instrument. To do this:

Go to “Configure” column/ select “Auto Configure”/ Backup Instrument.

13. To retrieve data or directly print a report: Select "Data", and then select the desired download or report to

view or print (Download: Profiler, Alarm log, IOR Snapshot, Configuration Log, Modem Error Log) (Print:
