Transport and storage
Unpacking
Energy meters are measuring devices and must be handled with care.
To protect against damage and soiling, they should only be unpacked immediately prior to installation.
Transport
The transport of the meter is permitted only in the original package.
When sending wireless measuring instruments / components by air, disable the wireless (place in aircraft mode) before shipping.

Installation of energy meter (fig. I)

• Depending on the design and application (heat or cooling meter), the energy meter is installed in either the hot or cold line of the system.
• The flow sensor must be installed so that the flow direction matches the arrow direction on the sensor.

Depending on the version, the flow sensor must be installed in flow or return.
The installation position is displayed in the info loop 3.5 (see “Information loop (3)” page 46) and, if necessary, also by means of a pictogram.

| | No pictogram (Installation position can be  set on site, see 6.1 page 33)
---|---|---

• Calming sections are not necessary before and after the flow sensor.
  For systems without temperature mixing, a straight DN 3 – 10 section upstream of the flow sensor is recommended.

The meter can be installed in both horizontal and vertical pipe sections, provided air bubbles cannot collect in the meter.
The flow sensor must always be filled with liquid.
Avoid frost at the meter.

• We recommend installing the flow sensor in a tilted position.
• The minimum system pressure must be 1 bar to avoid cavitation.
• Electrical and magnetic fields might disrupt electronic components in the energy metering device. Make sure there is sufficient distance (approx. 10 cm) between the  calculator and its measurement signal lines and possible sources of electromagnetic disturbance (e.g. trans- formers, electric motors, supply lines, etc.).
• If possible install the cables of the flow sensor or temperature sensor freely suspended (not bundled – aerial effect) with sufficient distance from electromagnetic  interference sources.
• The measurement signal lines (temperature and flow rate) must not be routed in direct proximity to other lines, such as mains supply lines, low-voltage supply lines and  data transmission cables. The minimum distance of 5 cm for low-voltage lines must be observed according to EN 1434-6.

• For medium temperatures from 90°C or for T Water < T Ambient (cooling meter application or heat meter with cooling tariff application) the cal- culator must be  removed and fitted at a sufficient distance from any heat sources. A wall holder (supplied with meter) or a spacer holder (optional) is available for this purpose.

• It is recommended that shut-off valves are fitted before and after the energy meter to simplify removing the meter.
• The meter should be installed in a conveniently accessible position for service and operating personnel.
• Initial operation is to be carried out and recorded after installation.

Temperature sensor

Disconnectable temperature sensors or temperature sensors not secured with their own calibration sticker must have their own EU approval and CE label.

Handle the temperature sensor carefully!
The sensor cables are provided with coloured type plates:

• Red: Sensor in the hot line
• Blue: Sensor in the cold line
• The maximum cable length of the temperature sensors is 6 m for the PT100 and 10 m for the PT500.
•  The connecting cables must not be shortened or extended.
•  The free temperature sensors can be fitted so they are directly sub- merged (e.g. ball valve) or in a pocket tested for conformity for this sensor type.
• Sensors must be installed symmetrically.
• After initial operation of the meter, ensure that the temperature sen- sors are always correctly connected at the calculator.

4.1 Installation in the ball valve with adapter
(coupling set in a separate bag)
Use ball valves with installation option for temperature sensor with thread M10 x 1.

Preparatory measures

• Close the ball valve.
• Unscrew the plug screw from the ball valve.

Installation (see fig. II)

1. Place the O-ring from the attached coupling set (type A or B) on the mounting pin.

2. Insert the O-ring with the mounting pin into the sensor hole of the ball valve (turn the mounting pin).

3. Position the O-ring in its final position using the other end of the mounting pin.

4. Fastening screws
   Type A (plastic) – plug the fastening screw onto the temperature sen- sor.
   Type B (brass) – insert the temperature sensor in the fastening screw and place the sensor in the mounting pin. Press in the dowel pin com- pletely and remove the  mounting pin.

5. Insert the temperature sensor with the securing fitting in the ball valve and manually tighten (2-3 Nm).

Power supply

5.1 Battery
A 3.6 VDC lithium battery is fitted in the standard version.
The battery must not be recharged or short-circuited.
Ambient temperatures below 35 °C have a positive effect on battery lifetime.
Used batteries must be disposed of at suitable waste collection points! Caution: Risk of explosion if battery is replaced by an incorrect type.

5.2 Power supply unit
Power supply units of 24V AC or 230V AC can be changed or supple- mented at any time.
It is strictly necessary to have the protective safety cover ins- talled at all times.
Under no circumstances connect between the two phases other- wise the power supply unit will be destroyed.

• The cable is to be fused at max. 6A and protected against tampering.
• The power supply unit notifies the meter if mains voltage is present.
• If the power supply fails, the backup battery (CR2032) provides the power supply for up to 1 year. The LCD readings (on pressing button) and the date and time are still updated, but none of the measuring functions work, incl. the flow rate measurement. Communication still functions over the optional M-Bus, RS485, RS232 modules or  the opti- cal interface, but reduces the life of the backup battery. The wireless function is switched off in the event of power supply failure.

Start-up operation

Once the meter has been installed, the components (calculator, volume measuring component and both temperature sensors) must be sealed with a tamper-proof seal and the  meter started up by a specialist com- pany approved according to the legislation.
Check the display for a plausible indication of flow rate and tempe- ratures.
User guide for further Information is available at https://www.diehl.com/metering/en/support-center/download-center/

6.1 Flow/return setting (optional ex works)
Optionally, the installation position of the meter can be set in-situ in loop 3 (“3.5” page 46). Consequently installation in the inlet (flow) or outlet (return) is possible.

This setting must be made prior to initial operation of the meter.
As supplied, the outlet (return) is pre-set and is shown as follows in the display.
Setting and number of possi- ble changes.

To changeover, switch to the “OutLEt” window in loop 3 (see 9. Operation).
Pressing and holding the button for > 6 s changes the display/setting to “InLEt”.
This setting can be changed a total of 8 times by pressing the button.

The display changes during the 6 s.
This does not influence functioning.

Sequence during changing

Button pressed <3s Button pressed >3s
If the button is pressed and then held for > 6 s, the meter performs the command shown in the display.

In each change, the framed number in the display reduced by 1.
After 8 changes, it is no longer possible to change the installation position.
The possibility of changing lapses either immediately upon detection of water, or after three hours’ operation without error detection (pre-set ex works).

The following indication appears in the display (example):
The changes indication dis- appears.![DIEHL SHARKY 775 Ultrasonic Energy Meter

• fig 8](https://manuals.plus/wp-content/uploads/2023/01/DIEHL-SHARKY-775 -Ultrasonic-Energy-Meter-fig-8.png)

When changing the installation position, the sensors must be matched to the actual installation (see chapter 4).

Expansion modules

The energy meter has two slots for expansion modules.
They can be mixed, but two pulse modules of the same kind must not be installed.
The analogue module occupies both positions.
These modules have no effect on consumption recording and can be fitted retrospectively without damaging the verification mark.

The relevant ESD regulations (electrostatic discharge) must be observed.
No responsibility is accepted for damage (especially to the electronics), resulting from non-observation of the rules.

7.1 Module installation (fig. III)

1. Open the calculator by folding down the side catches.
2. Lock the module into the appropriate slot and carefully connect the pre-formed ribbon cable at both ends.
3. Close the lid and check the meter for correct operation by pressing the push button. Apply the tamper-evident seal of the housing lid if the meter functions correctly.

7.2 Communication
Communication modules must be secured so that opening of meters is only possible by destroying the securing points.
The calculator supports three communications channels.
Two additional communication modules can be used in wireless operation.
Both communication modules have their own primary address. Both ports have a common secondary address, which is set to the serial number ex works.
The protocols may be different for all three communication channels and are pre-set ex works. The telegrams can be defined for each customer using the IZAR@MOBILE 2 software.

7.7.1 Activation
Upon delivery, NB-IoT module has a standard configuration. To change the configuration, please download the OTC Application (One-Touch com-missioning) for Android,  available in Google Play store. The OTC connects to the module via NFC.

Make sure to locate the NFC antenna on your phone. When you scan or write new configurations to the module, you should place the phone’s NFC antenna as close as  possible to the NFC antenna of the module. The NFC is reachable from back side of the meter or from top when lid is removed.

By default, the product is set to passive mode, which means no messages will be transmitted from the device. There are two ways to activate the product:

• Press and hold down the push button (5) for at least 5 seconds until the green LED (1) lights up.
• Via the OTC mobile application. Go to the Apply tab, set the Power mode to “Active”, push “Apply” and place the phone on the back side of the meter, next to the  module. Make sure to hold the phone still until the phone vibrates.

Upon start-up, the module will attempt to connect to the mobile network.
The phase is indicated by short flashes on the green LED. After success- fully connecting to the mobile network, the green LED will light up for 8 seconds, as indicated by  the figure below.

7.8 Test output
The internally located test output is intended for testing laboratories.
The manufacturer supplies two special cables:

1. Volume testing pulses
2. Energy testing pulses
   Please refer to the inspection and testing manual for further specifications (pulse weighting, pulse duration/pause, pulse frequency).

Ensure that the temperature sensors (measurement resistances) remain in contact without interruption during energy verification.

Display

The data generated by the calculator can be viewed in several displays.
These displays contain the assigned system information (e.g. energy quantities, water volumes, operating days, water quantities, actual tem- peratures, maximum values) and can  be accessed by calling the displays in the pre-defined sequence / loop. The energy meter has up to 6 diffe- rent display sequences / loops.
Main loop, due date loop, information loop, pulse input loop, tariff loop.
The month loop comprises up to seven readings alternatingly displayed for 2 s – 4 s each. For quick visual identification, the loops are labelled 1 to 6 in the display. As  standard, the main loop contains the actual data, e.g. energy, volume, flow and temperatures. The verified register is marked with a padlock icon.

Operation

Use the push button to page through the individual displays. When doing so a differentiation is made between short and long button presses. With a short button press (<3  seconds) you get to the next display within a loop; with a long button press (>3 seconds) you get to the next display loop. The “Energy” window (sequence 1.1) of the main  loop is the basic display. If the button is not pressed for approx.4 minutes, the meter automatically switches off the display to save power (exception: an error exists). If you press the button again, the meter returns to the basic display.

Display Error codes

If an error occurs, the error code is displayed in the main loop. All win- dows, however, can still be accessed by pressing the button. If the button is not pressed for approx. 4  min, the error code is automatically displayed again.
The error message disappears automatically as soon as the source of the error is corrected. All errors that exist for longer than 6 min, are saved in the error memory.
