ELECTRICAL WIRING

NOTICE

and Air-Conditioning Engineers, Inc., 2010.

NOTICE

Figure 1 shows how to connect the TUF in a network containing a common power

supply. Use a cable containing two twisted pairs. One pair is to be used for RS 485/ BACnet [+] and [-]. The other pair is used for power and common. This conguration is suitable for AC and DC supplies. Care should be taken that there are not too many

devices powered from the same supply as voltage drops will occur in the wiring. If you

have many devices, or have long cable runs, the local supply conguration may be a

better choice.

Figure 2 also shows how to connect the TUF in a network containing individual local supplies. Use a cable containing a twisted pair and a single conductor. The pair is to

be used for [+] and [-]. The single conductor is to be used for common.

All devices in the network should be daisy chained. Star connections and T connections

are not permitted.

Accessing the Measurements

The analog input object AI1 through AI4 are for viewing the pressure measurement in

the desired engineering units. The object property tables for these analog input objects

can be found in Appendix III.

Analog value object AV1 through AV4 are for viewing the Air Velocity or Air Flow

calculated values in the desired engineering units. The object property tables for the

analog value objects can be found in Appendix IV.

Accessing the Measurements

The analog input object AI0 through AI2 and AI5 through AI7 are for viewing unit measurements in specic engineering units. The object property tables for these analog input objects with appropriate engineering units can be found in Appendix II.

Analog value object AV0 through AV21 are for viewing additional information such as

meter mode, balance sheet and time. The object property table for the analog value

objects with appropriate units and formats can be found in Appendix III and IV.

ADDITIONAL NOTES:

1. The communication write status features a power off save, where the last communicated information will be saved upon powering off the unit.

2. Information is accessed at a rate of 1 per minute.

3. Communication time is linked to the meter clock, and will automatically reset on power on. If the time needs to be corrected and is updated via the communications the meter clock will automatically update.

4. With respect to the accumulative heating capacity, accumulative cooling capacity and accumulative ow in the variable table, when this information is transferred

via communication only whole numbers will be uploaded. The decimal portion of

the reading will only be displayed on the TUF meter LCD screen.

Changes to Max Master and Max Info frames require a power cycle/reset to take effect.

INSTALLATION INSTRUCTIONS

BALL

TEMPERATURE SENSOR

1. Install the meter as shown in either Figure 1 or Figure 2.

2. Mount the temperature sensor with the blue tag on the corresponding return pipe on application. The sensor with the red tag has already been installed in the meter.

3. Flush the system in the proper direction until:

• No impurities remain in the lter and pipe.

• No water leaks when pressure is added to the system.

• The humidity inside the enclosure containing the meter does not exceed 93%.

4. After ushing for a period of time; close the ball valves on either side of the meter and ush the impurities out of all lters. *3.6 V ER26500 battery may be purchased separately to power display only.

INSTALLATION REQUIREMENTS

NOTICE

1. Ensure that there is a 10 diameter straight run of pipe upstream and a 5 diameter

straight run of pipe downstream form the meter.

2. See the installation positions in Figure 3, in which A and B are the proper installation positions, while C and D are the improper positions.

3. If the meter is installed on the horizontal pipe, it must be oriented at least 45° from horizontal (see Figure 4). If the meter’s face is horizontal, then debris accumulation can increase inaccuracies (see gure 5 for correct and incorrect orientations).

There is no special requirement when installing on the vertical pipe work. Note: the meter can be installed on the return pipe or the supply pipe according to

user’s needs, but it should be selected in advance.

If the following requirements are not followed, then large air

particles and impurities in the pipe could inuence the meter’s

measuring accuracy.

INSTALLATION NOTES

NOTICE

using digital communication protocols.

NOTICE

CAUTION

people and damage the meter.

1. Avoid tugging on the temperature probe’s cables.

2. Ensure the water is owing in the direction indicated by the arrow on the meter’s

body.

3. If several meters are installed on the same vertical pipe work, each meter should be separated from the others to avoid pipe leakage or fallen debris that could affect

the other meters’ operation.

If not specied at time of order, refer to appendix III to change from

supply to return programming. Change from supply to return, and vice-versa, is only possible

Do not directly weld the meter on to the pipe; the extreme heat will damage the BTU meter’s internal elements.

Do not install the meter near a high temperature heat source such as during electro gas welding. Doing so after installing an optional battery could cause the battery to explode and cause injury to

increases the accuracy of low and high end measurements where other, more narrow ranged, devices are inaccurate

• Horizontal or vertical installation

• Communication output ports can be used for automated meter reading

• Automatic diagnostic function. An error code will be displayed on the screen to

indicate the problem

• Ability to install an optional 3.6 V battery that can last up to 6 years

DISPLAY

1. Switching Between Information

Holding down the button for > 1s will switch the sections from curren information ▲, to monthly information ▲▲, and then to other information ▲▲▲. Once in the

desired section, pressing the key will switch the information shown for the given section.

2. Display Units Energy is displayed in kW•h, power is displayed in kW, ow volume is displayed as

m3, and ow-rate is displayed in m3/h.

3. Display Details a. “Monthly Reading Date” is displayed as “Pd= XX”, in which XX is the end date of the current month’s energy summation. The factory default value is 31,

meaning that the monthly recording period ends at midnight on the 31st day

of the month. At this time the current month’s cumulated energy will be stored and the system will begin to record the next month’s energy.

b. The meter can store and display the recordings from the past 18 months.

c. The units for “Sum of Working Time” (hours) is displayed as h.

d. “Software and Protocol Editions” are displayed as “UEr.X.X X.X”. The rst X.X is the software edition code and the second X.X is the communication

protocol edition code.

e. “Leaving-factory serial number” is the meter’s identication number, which is the same as the one in the external label. This serial number is a unique

number set by the factory; it is also the secondary address in M-BUS system.

f. Battery Voltage displays “UCC=X.XX” (the default unit is Volts). When the battery’s voltage capacity is lower than 2.9±0.1 V, “ ” will appear on the

display. This symbol will not appear if no battery is installed.

g. If there are any unresolved errors, the start date will display as normal but the

end date will display “00-00-00”, and then the error message will be displayed.

NOTES

1. If meter is not in use during freezing conditions, drain all water from the connecting pipe. Low temperatures will cause the water to freeze in the pipe and damage the meter.

2. This device is intended to be used with clean water. While dirty water will not

damage the meter, it will cause errors in the reading.

3. A lter should be mounted near the meter and cleaned regularly.

4. If the heat exchanging system is operating normally, but the instantaneous ow rate of the heat meter reduces signicantly, then there is too much dirt in the lter. This will narrow the pipe and reduce the ow. Cleaning the lter will x the problem.

5. To protect the meter and avoid damage from harsh conditions, it is recommended

that the meter be encased in an enclosure.
