Description

NovoCon® S

NovoCon® S is a high accuracy multi-functional field bus actuator, specifically designed for use in combination with the Pressure Independent Control Valve type AB-QM in sizes from DN 10-32. The flow is modulated by the AB-QM pressure independent control valve to avoid overflow and reduced boiler and/or chiller efficiency.

The actuator with AB-QM is used to control water supply to fan coil units, chilled beams, induction units, small re-heaters, re-coolers, AHU’s and other terminal units for zone control, in which heating/ chilled water is the controlled medium. Due to its accuracy, remote functionality and flow indication features, this product facilitates an accelerated commissioning process, allows easy maintenance, improves indoor comfort, increases energy savings and allows for fair cost allocation of heat/cool energy.

The high position accuracy of the actuator, together with the pressure independent and linear characteristic of the AB-QM valve, allow NovoCon® S to be used as a flow indicator. Setup of the actuator and valve parameters are made via fieldbus. Control is achieved via field bus or via analog inputs to NovoCon® S.

Typical applications are:

• Radiant ceiling panels, supplied by 4 pipes (Heating supply and return and cooling supply and return).

• Fan coil units, with single coils supplied by 4 pipes (Heating supply and return and cooling supply and return).

General features:

• Remote commissioning/Pre-set/Flush features

• Flow, power emission and energy indication

• High position resolution and accuracy

• Energy management algorithms

• 4/2-pipe changeover applications

• I/O applications

• LED bar displaying status and alarms

• No tools required for mounting

• Maintenance-free lifetime

• Self-positioning process

• Low-noise operation

• Plug-in halogen free cables

• Auto MAC addressing for BACnet

• Auto baud rate detection

• Intrinsic alarm reporting for BACnet

• Valve blockage alarm

• Broken wire detection on analog control and ground signal

• Choice of BACnet MS/TP or Modbus RTU in the same product

• Mis-wiring protection on any wire up to 30 V

Combined with the Actuator NovoCon® ChangeOver6, NovoCon® S offers a unique solution in controlling both the AB-QM valve and a 6-port motorised ball valve that performs a diverting function between two water circuits in 4-pipe changeover systems.

This diverting function, primarily used for radiant panels, also allows the cooling and heating capacity of a fan coil unit to be increased for the same compact size compared to a double coil model where the heating and cooling water circuits each have their own coil.

The 6-port diverting valve and actuator work in combination with an AB-QM PIBCV valve and NovoCon® S bus actuator. The AB-QM balances the flow and the NovoCon® S bus actuator controls the flow. NovoCon® S also controls the 6-port diverting valve actuator which switches between heating and cooling. This unique functionality is characterized by the following:

• There is only one single field bus and power supply connection cable to the NovoCon® S actuator. This powers both the NovoCon® S and controls the 6-port actuator. Furthermore, there is feedback from the 6-port actuator to NovoCon® S.

• The NovoCon® S actuator automatically faultdetects, by means of comparing 0-10V control & feedback signals, if the 6-port actuator is in manual operation mode, removed from the valve or if the 6-port valve is blocked.

• The NovoCon® S actuator has two Design Flow Rate pre-settings: one for heating and another for cooling.

• The NovoCon® S actuator indicates power emission and logs energy consumption for heating and cooling energy based on flow, supply and return pipe temperature measurement.

• While in maintenance mode, the 6-port actuator is able to fully close the valve and prevent any leakage, thereby saving on stop valves.

• Logic contained within the NovoCon® S actuator, ensures that only one actuator in each pair (NovoCon® S and 6-port valve actuator) drives. This ensures that 2 actuators in the pair never drive at the same time. This reduces voltage booster demands in daisy chains.

• The NovoCon® S actuator detects if the 6-port actuator cable is disconnected. If this is the case an alarm is initiated.

Features CO6:

• NovoCon® S + ChangeOver6 actuator represents only ONE device on the fieldbus network needing no physical I/O

• No cross-flow between heating and cooling

• Simple connection and control

• Feedback for position status and alarms

• Quiet and reliable operation

• Maintenance free

• Teflon seal and polished chrome valve ball to

prevent valve sticking

• Blocked valve alarm

• Manual override

No tool is required to mount the actuator on the valve. Installation of the valve with the actuator is allowed in the horizontal position or upwards. Installation downwards is not allowed. The actuator must not be installed in an explosive atmosphere, at ambient temperature lower than 0 °C or at ambient temperature higher than 50 °C. It must not be subject to steam jets, water jets or dripping liquid.

Note: The actuator may be rotated up to 360° with respect to the valve stem by loosening the retaining fixture. Once the actuator is in place, retighten the retaining fixture.

Note: The cable and cable gland/grommet used, must not compromise the actuator’s IP rating. There must be no strain on the connectors. The rubber cable grommet delivered from factory do not compromise the IP rating but do not provide full strain relief according to the LVD directive. Please observe local rules and regulations.

Digital port

Galvanic separation shall be provided for segments crossing buildings. Common ground shall be used for all devices

Multifunctional port

on the same network inclusive router, gateways etc.

Digital port

All bus connections in the cables are made with twisted wires. The cable type used for NovoCon® analog, digital and I/O cables is AWG22/0.32mm2. If other cables are used to extend the length, always use twisted pair wire for bus signal and include ground for the bus signal. The recommended cable type is AWG22/0.32 mm2. If used for longer distances please use a AWG20/0.5mm2 or AWG18/0.75mm2 cable. The cable’s impedance characteristic shall be between 100-130Ω. The capacitance between conductors shall be less than 100 pf per meter. The length of the cables influence on the communication speed. Longer cable lengths should result in lower baud rates. The total maximum cable length allowed per network is 1200m. Use a minimum 20 cm distance between 110V/230V/400V power line cables and bus cables. NovoCon® S has mis-wiring protection on up to 30 V AC/DC on all wires, but be aware that if 30V AC are connected to the Analog input, the external power supply will see this as a short circuit and blow the fuse in the external power supply.

T-junction connections (stub lines) are not recommended. In the event of T-Junction connections being used the following limitations must be adhered to:

- max T-junction cable length 1.5m (shortest standard digital cable)

- total length of Network max 640m (+ 100m stub length)

- max baud rate 76 kb/s 1)

- max number of devices on network 64 1)

- main cable should be standard RS485 bus, twisted pair, min thickness AWG22 / 0.32mm2.

When using less than 32 devices you may attempt to raise the speed to 115 kb/s.

Star topology

Star topology is not according to the RS485 standard and should not be used with NovoCon® S, M and L/XL.

DC Power supply (recommended)

When daisy chaining with 10m NovoCon® cables and using a 24V DC power supply, additional voltage boosters/power supply is needed when 12 NovoCons in series is exceeded. See table below.

AC Power supply When daisy chaining with 10m NovoCon® cables and using a 24V AC power supply, additional voltage boosters/power supply is needed when 7 NovoCons in series is exceeded. See table below. Important: The power supply used must be able to deliver 60% more power than the nominal rating of NovoCon® S.

Daisy chain

1.5m

If the supply voltage to the first device in the daisy chain is lower than 24V AC/DC, or long thin cables other than NovoCon® cables are used, then the quantity of devices in the daisy chain may have to be reduced.

The recommended maximum quantities of NovoCon® S are 64 pcs in one daisy chain connection. If other BACnet devices are added with NovoCon® S in the same daisy chain connection, Danfoss recommends a maximum of 32 pcs. to ensure sufficient network speed.

Danfoss recommends that NovoCon® S should be used on its own sub-network for optimal performance.

General requirements and recommendations:

• Use Danfoss daisy chain cable to connect two NovoCon® S devices.

• Use Danfoss digital cable to connect NovoCon® S with another BACnet device.

• The current in cables should not exceed 3Arms at 30°C.

• Use the termination resistor (DIP switch 8) at the end of daisy chain.

• Voltage boosting may be achieved via any port.

• Generally, one power supply is preferred.

• If two power supplies are used, they must have the same polarity and the same common ground.

• A common ground must be used for all devices on the same sub-network, including routers and gateways.

• Galvanic separation shall be provided for segments crossing buildings.

• Total maximum sub-network cable length is 1200m.

Multiplexers and relays (analog-digital-analog convertors) in combination with NovoCon® S, may be used to gather information on, or control on/off devices.

Using NovoCon’s 0-10V output signal (AO:0 / 33286), multiplexer relays convert this signal in order to switch devices on or off e.g. 7V signal from NovoCon® S is converted inside the multiplexer so device1=on, device 2=on, device3=off. E.g. 4V signal from NovoCon® S is converted inside the multiplexer so the device1=on, device 2=off, device3=off.

Using NovoCon’s 0-10V input signal (AI:0 / 33216) received from the multiplexers, the DDC can decipher the meaning of the voltage signal e.g. 7V signal to NovoCon® S from the multiplexer is deciphered by the DDC as meaning device1=on, device 2=on, device3=off. 4V signal to NovoCon® S from the multiplexer is deciphered by the DDC as meaning device1=on, device 2=off, device3=off.

The ChangeOver6 is a 6-port valve with a rotary actuator that switches the flow between heating and cooling. An AB-QM pressure independent balancing and control valve with an actuator is used to balance the system and modulate the flow. When using the NovoCon® S for flow control, both NovoCon® S and the Actuator NovoCon® ChangeOver6 are represented on the fieldbus network and need no physical I/O for control.

Anti-sticking requirements:

Cooling:

To reduce the risk of the ball valve sticking due to water quality, the valve must be partially rotated at least every 7 days. This is a factory default setting and is handled by the object MSV:11 / register 32812.

Normally cooling is connected to port 1 and 4 and heating to port 5 and 6. If, for some reason, this is not the case, then Inverted CO6 mode (MSV:9/32810) must be used instead.

CO6, contrary to other ball valves, includes a shut off function. This function should only be used during maintenance and not during operation. This replaces the need for four ball valves. The Shut off command can only be performed when the Flow Rate Setpoint (AV:1/33280) is 0.

Application mode State 3: CO6 Mode

Normally cooling is connected to ports 1 and 4 and heating to ports 5 and 6. If that is not possible, then this may be switched and state 4: Inverted CO6 Mode must be selected.

NovoCon® S and the ChangeOver6 actuator communicate with voltage control and feedback signal. Whole functionality is available by using simple bus commands. For easier technical understanding, please see below detailed explanation of the communication between NovoCon® S and the ChangeOver6 actuator.

BACnet objects and Modbus registers usage (continued)

- Advanced configuration and features

If the default setup of the actuator isn’t suitable, special attention has to be payed to the following objects: MSV:9 / 32810 Application mode MSV:3 / 32802 Selected Valve Type MSV:10 / 32811 Application command & status AV:30 / 32796 Design Flow Rate Heating AV:31 / 32798 Design Flow Rate Cooling MSV:0 / 33284 Actuator Mode and special features AI:1 / 33218 T1 value, temperature or resistance input AI:2 / 33220 T2 value, temperature or resistance input AI:3 / 33222 T3 value, temperature or resistance input AV:32 / 33288 Power emission MSV:13 / 32815 Energy management

Application mode:

The default Application mode is Digital Control. In this mode the NovoCon® M is controlled via fieldbus and the voltage inputs and outputs are available to connect other devices. Alternatively, in Analog Control mode the NovoCon is expecting an analog control signal.

Selection of AB-QM valve type:

After selecting Application mode (see above), it is then necessary to select the AB-QM valve type that the actuator is mounted on. This is done with the object MSV:3 / 32802 Selected Valve Type. The present value of MSV:3 / 32802 may be set to values between 1 and 9. Each number represents a specific AB-QM valve type, which can be found in the table: Valve type selection. The default value for MSV:3 / 32802 is 1 i.e. AB-QM ISO DN40 valve.

Selection and setting of engineering units:

If there is a need to change the default engineering units, this is done in BACnet via the object’s engineering units property or in separate objects, and in Modbus via separate registers. See the BACnet and Modbus tables for more details.

Setting the Design Flow Rate:

The designed maximum flow rate of the controlled system should be set if the nominal flow of the valve does not correspond to the designed maximum flow rate. The Design Flow Rate is set by changing the present value of:

• AV:30 / 32796 Design Flow Rate for Heating applications

• AV:31 / 32798 Design Flow Rate for Cooling applications

Temperature measurements:

AI:1 / 33218 Temperature T1 or resistance input, AI:2 / 33220 Temperature T2 or resistance input and AI:3 / 33222 Temperature T3 or resistance input are used to measure the temperature with temperature sensors. The resistance value may also be shown directly if selected, allowing these inputs to be used for other purposes than measuring temperature e.g. window contacts or other potential free contacts. Closed circuit <900Ω, open circuit 100kΩ.

Power emission:

AV:32 / 33288 Power emission is used to show the present hydronic power emission of the terminal unit, based on calculations from water flow rate and the temperature difference between supply and return pipes.

Energy Counter:

Either the Cooling or Heating thermal energy used is counted and logged under AV:33 / 33290 or AV:34 / 33292. This function is enabled and disabled with MSV:12 / 32814.

Flushing a system:

Actuator Mode and Special Features MSV:0 / 33284 has an option which allows the user to flush the system via the fieldbus. To start flushing the system, set MSV:0 / 33284 to 3, Flush. The actuator will then open up the AB-QM valve completely. Flush will end when:

• MSV:0 / 33284 is set back to 1 = Normal operation

• Or the power is cycled.

• Or the flush function times-out after 1 hour. When flushing ends, the actuator returns to normal operation.

De-Airing of a system:

With MSV:0 / 33284, is it also possible to start the De-Air function in the actuator. This function will open and close the AB-QM valve a number times, helping getting rid of trapped air in the hydronic system. Start De-Air by setting MSV:0 / 33284 to 4. De-air will run undisturbed until it ends. The state of the actuator will then go back to normal operation i.e. MSV:0 / 33284 = 1, Normal.

Controlling the actuator:

Under normal operation (Digital Control) of the actuator, where the flow through the AB-QM valve is to be controlled, the object Flow Rate Setpoint AV:1 / 33280 is used. The default setting for the Flow Rate Setpoint engineering unit is %.

This is the most suitable setting as the controller does not need to know anything about the Design Flow Rate setting of the actuator. The output signal from the controller needs only to be set up so it regulates from 0 to 100% of the Heating Design Flow Rate AV:30 / 32796 or Cooling Design Flow Rate AV:31 /32798. Alternative Design Flow Rate AV:0 / 32768 can be used. To change the flow rate through the valve, the present value of AV:1 / 33280 is written-to, in the range 0 – 100%.

If the engineering unit selected for AV:1 / 33280 must be l/h, the Flow Rate Setpoint through the valve must be written-to in integers representing l/h. An example of this could be a controller writing values to the actuator in the range 0 to 7500 l/h for a DN40 valve.

Alarms and warnings:

System issues can be detected by using BACnet object values BV:10 to BV:24 or Modbus register 33536, see BACnet and Modbus tables for more details.

Optimize BACnet network speed

Energy management MSV:13 / 32815

Reducing Unnecessary PollforMaster Traffic

The MAX_MASTER setting in NovoCon® S can be set above the number of the highest used MAC address in the MS/TP sub network. The MAX_MASTER property is found in the Device object and has a default value of 127. If used, it should be noted that the MAX_MASTER property value should be adjusted accordingly at a later stage prior to adding more devices to the network when the highest MAC address exceeds the MAX_MASTER property value.

Important: Before MAX_MASTER can be set, ensure ALL network device MAC addresses are below the intended MAX_MASTER property value. Failure to do this may result in network communication problems.

Allocating Correct INFO_FRAMES

Setting for Controller: Network Routers and Controller devices that transport traffic in the MS/TP network require a higher number of INFO_FRAMES than NovoCon® S. Therefore, these devices should have a higher value than NovoCon® S. A general rule of thumb for the sub network router’s MAX_INFO_FRAMES property value is equal to the amount of MS/TP devices in the router’s sub network. The MAX_INFO_FRAMES property is found in the Device object of MS/TP devices. NovoCon’s default MAX_INFO_FRAMES value is 1.

General Information - Energy Limitation States:

For all ‘limitation’ states within MSV:13/32815, a warning will be activated and made visible on the bus to inform the user that NovoCon® has taken control of the flow rate through the AB-QM valve. Whilst under NovoCon® control, the valve will not be closed at any time i.e. closing % constraints are contained within its algorithms, although an external device’s control signal will always be able to close the valve. If the energy limitation settings are unobtainable without NovoCon® closing itself, a warning will be activated to inform the user that the set-point value is ‘out of range’. Please note that NovoCon® will not automatically relinquish control of the flow rate as soon as the set-point is achieved if the external device e.g. DDC differs greatly with that of NovoCon’s® calculated flow rate/opening %. TIP: This information may be used by the user to improve the external control device’s PID.

General Information - Energy Control States:

For all ‘control’ states, except Power control, within MSV:13/32815, NovoCon® takes full control over the flow rate through the AB-QM valve and will not accept a control signal from an external device. Whilst under NovoCon® control, the valve will not be fully closed at any time i.e. closing % constraints are contained within its algorithms. If the energy control settings are unobtainable without NovoCon® closing or opening itself fully, a warning will be activated to inform the user that the set-point value is ‘out of range’.

If MSV:13 (energy application) is switched from "not used" to:

- power limitation/control or delta temp. lim./control: T1 function and T2 function are locked to Supply/ return temperature – these cannot be changed until app is disabled.

- return temp. limitation/control: The terminal corresponding to "return temperature function" is locked and cannot be changed until energy app is disabled.

Power Manager

State 1: Not active

Energy management applications are disabled.

State 2: Power limitation (chilled water example)

NovoCon® S calculates the instantaneous hydronic power used and will then, when required, override the DDC control signal and limit the flow rate / hydronic power according to the user defined values in object / register AV:35 or 36 / 32832 or 32834. The hydronic power is limited by closing the valve until the kW value measured, once again, falls below the defined limit. There are user defined limits for both Cooling Power and Heating Power. When this limitation is active, the warning object BV:23 / bit 23 in register 33536 will be set to ‘on’. Application example: When the “Power” is limited in this way we are able to prevent over consumption (during peak load) and balance design power distribution.

State 4: Min. Delta T limitation (heating water example)

NovoCon® S, when required, overrides the DDC control signal and maintains a minimum temperature difference between the flow and return temperatures by starting to close the valve when the user defined minimum delta T is not achieved. As the flow temperature increases/decreases, so will the calculated minimum set-point for the return temperature. This always ensures a minimum energy transfer to the FCU irrespective of the flow temperature. This state may also be used in CO6 mode and will apply the appropriate value whilst in cooling/heating mode. For heating, the delta T value is set in object / register AV:37 / 32836. When conditions allow for this limitation to be activated, the warning object BV:23 / bit 23 in register 33536 will be set to ‘on’. Application example: When we would like to improve the efficiency of boiler/chiller we can define the Minimum Delta T in the system with respect to outside temperatures.

State 5: Set Delta T control (heating water example)

NovoCon® S constantly overrides the DDC control signal when activated and maintains a constant temperature difference between the flow and return temperatures by opening and closing the valve. When the flow temperature increases/decreases, so will the calculated delta T set-point for the return temperature. This always ensures a constant delta T across the FCU irrespective of the flow temperature. This state may also be used in CO6 mode and will apply the appropriate value whilst in cooling/heating mode. The constant delta T for heating is set in object / register AV:37 / 32836 and for cooling AV:38 / 32838.

State 7: Set Return T control (heating water example)

A constant return temperature T2 value is set in object / register AV:39 / 32840 (Heating) or AV:40 / 32842 (Cooling). NovoCon® S constantly overrides the DDC control signal and maintains a constant return temperature by opening and starting to close the valve when the user defined Return T is exceeded or not achieved. When the flow temperature increases/decreases, the Return T set-point remains the same. This will ensure a constant return temperature back to the energy source. Application example: When we intend to use the return water for secondary usage e.g. pre-heat on a AHU or a standalone terminal unit in which the T2 value is used as the temperature set-point to be maintained.

Commissioning/connection of flow sensor to:

NovoCon® S

NovoCon® S supports connection of flow sensor directly to NovoCon® IO cable. Flow sensor must be connected to AI and AO terminal. NovoCon must be set to digital mode (MSV:9/32810 = 2), output functionality set to Inactive (BV:3/32817 = 0) and value of output (AO:0/33286 = 10) on 10 V. You also need to select AI (MSV: 41/32821) input for connecting flow sensor.

To get right flow sensor value it is very important to set right value of liters per pulse on NovoCon® (AV: 43/32864). Usually this is written on flow sensor specification sheet. If we would like to use flow sensor for calculating energy we must also set register MSV12/32814*.

Settings connected to flow sensor (NovoCon S/M/L/XL): If either T1 or T2 ohmic input terminal is used for flow sensor or disabled:

energy app can't be switched to power lim./control or delta temp. lim./control, but might be switched to return temp. lim./control. The former depends whether if the return temperature function is selected on the other terminal, which is not used for flow sensor connection.

If analog input terminal function is used for flow sensor or disabled, the following application modes in MSV:9 are not available:

1: Analog control - AI used for control signal 3: CO6 mode - AI used for CO6 status 4: Inverted CO6 mode - AI used for CO6 status 7: Analog CO6 mode - AI used for control signal 8: Inverted analog CO6 mode - AI used for control signal In other words, the MSV:9 can't be switched to "Analog control" or to the CO6 modes except mode 5&6 (CO6 without alarms).

If MSV:9 application mode is used in "Analog control" or in combination with CO6 except states 5 and 6 (CO6 without alarms):

The AI terminal function is locked to state 2 "Analog input (voltage or current)" and can't be changed.

Auto baud rate

NovoCon® should be connected after, or at the same time as, other devices. NovoCon® will then adapt to it's network's baud rate automatically.

Baud rate MSV:6 / 32804 must be set to 1 (default).

If the NovoCon® observes activity on the bus within 45 seconds after powering up, then it adopts the baud rate presently used on the network by other BACnet devices. If the actuator does not see activity on the network within this time, it generates a token and sends the token out at the default baud rate of 38400bps.

Auto MAC Addressing

- BACnet only

MAC address assignment method MSV:5 must be set to 1 (default).

The NovoCon® actuator observes for occupied MAC addresses on the sub-network and then automatically assigns an available MAC address to the actuator only on first Power up. Assuming the address has not already been manually selected by DIP Switches. If a MAC address collision arises an Auto MAC addressing is enabled. This function will start the search for an available MAC address again. When an available MAC address is found, an “I-Am” notification will be sent out via BACnet. Please note that consecutive MAC addresses may not always be assigned.

By acti vating this featur e, the analog outpu t signal (AO:0) and th e position of the val ve opening become l inked. The volta ge output type a nd range is linked to t he MSV:1 present value. T his feature ma y be used for FCU fan con trol for example a nd is only made avail able when MSV:9 Applica tion Mode are in Stat e 1: Anal og control or State 2: D igital control. If BV:3 is ac tive and the analog o utput signal (AO:0 ) is written to manua lly it must be relin quished i.e. write “ NULL” to return to the origi nal setting of BV:3 .

Confli ct between th e Mechanical AB -QM valve sett ing and the NovoCon®. The m echanical valv e settin g must be 100% or above . The warning will a lso be activate d if the Selecte d Valve Type has diffe rent stroke than the a ctually valve us ed validated dur ing calibratio n.

Voltage of p ower supply is meas ured to be too high. When the m easured voltage e xceeds 43.4V the alar m will be turned ON f or too high voltag e. When the m easured voltage i s once more below 38 .3V, the alarm will be tu rned OFF.

Voltage of p ower supply is meas ured to be too low. If voltag e drops below 14.5V (N ovoCon S) or 19.0 (NovoCon M/ L/XL), alarm is ac tivated. If voltag e drops below 14.0V (Nov oCon S) or 13.0 (NovoCon M/L /XL), alarm is ac tivated and moto r disabled. If voltag e goes above 15.5V (Novo Con S) or 18.2V (NovoCon M /L/XL), alarm d eactivates and m otor is enabled.

There was a n error during cal ibration of the ac tuator. E.g. the Novo Con® actuator is not m ounted on the valv e or the valve is stuck .

ChangeOver6 actuato r is in manual overri de or is unable to reach p osition. When the re ason for the alarm i s removed it may take up to 2 m inutes before th e alarm is cleared.

When the notif ication class NC:0 is going to b e used to notify about cha nges with status of Warnings and Alar ms (BV:10 – BV24), is it necessary to su bscribe for notifications f or the entire day and week: From 0 0:00:00:0 0 to 23:59:59:99 and all 7 d ays of the week. This is because the ac tuator does not have a clock bu ilt in and will therefore not b e able to handle notificat ions with respect to time.

Temperature sensors

NovoCon® S

Functional description

The sensor unit consists of a platinum element, the resistance value of wich, changes proportionally with the temperature.

Pt 1000 ohm sensor (1000 ohm at 0°C). The sensor is adjusted and meets the tolerance requirements of EN 60751 Class B. The accuracy of temperature measurement is approximately 0.5° in typical operating range. It is unlikely, that during calculation of ∆T, deviation of both sensors would be summed up. Therefore, it is estimated that ∆T measurement accuracy is 0.5° when the sensors are mounted correctly. It is not recommended to use longer wires on temperature sensors than 3m due to risk of electromagnetic interference. If long or thin wires are used it may be necessary to make an offset of the temperature reading in the BMS system.

Trouble shooting

BACnet Fieldbus check:

It is possible to check the fieldbus state by examining error messaging related to the actuator in order to verify communication and detect early potential fieldbus related problems. This is done by the object values AV:15 to AV:19.

Quality of the BACnet network:

An important thing for good operation of the actuator is a well functioning network. Some values that tell you about the quality of the network can be found in the objects AV:15 to AV:19. The most important values are AV:17 Server Error Count and AV:19 Server Timeout Error. These two values should be much lower than AV:15, AV:16 and AV:18. As a general rule, it is important that AV:17 and AV:19 are not constantly increasing their count.

Quality of power supply:

The object / register AV:6 / 33794 may be used to check if the power supply and cabling, used to supply the actuator with power, is according to specification requirements. The present value of AV:6 / 33794 represents the current voltage measured inside the actuator. This is the voltage that the actuator monitors at all times and subsequently reacts on if outside the recommended range. See in the table below how the actuator reacts at different voltage levels.

Voltage (Pr esent value of AV:6 / 33794

Voltage below 14.5V (NovoCon S) or

19.0 (NovoCon M/L/XL) Voltage below 16.1V 14.0V (NovoCon S) or

13.0 (NovoCon M/L/XL) When voltage rises above 15.5V(NovoCon

S) or 18.2V (NovoCon M/L/ XL) again When voltage rises above 43.4V

When voltage drops below 38.3V again

Reaction

Start alarm indication with LED. Initiate and alarm BV: 15 / 33536 Bit 19 and that the supply voltage is too low.

Motor is stopped. The LEDs indicating alarm and actuator still initiating alarm BV:15 / 33535 Bit 19 if the voltage hasn't dropped too low.

Motor can run again. LED alarm indication stops and returns to normal operation. Alarm BV:15 / 33536 Bit 19 returns to normal operation.

Start alarm indication with LED. Initiate an alarm BV:14 / 33536 Bit 18. LED alarm indication stops and returns to normal operation. Alarm BV:14 / 33536

Bit 18 returns to normal operation.

NB: the voltage level will be constantly changing depending on the operational activity of the entire group of actuators and other devices connected. The supply voltage will go up and down in value if:

- Power supply is not strong and stable

- If long cables are used in a daisy chain setup A higher number of actuators running at the same time will reduce the supply voltage (for the last

devices on a daisy chain cable, in particular). The actuator’s voltages are considered to be OK when all values of AV:6 / 33794 are above 18V, when

all actuators are moving the motor/running. To ensure voltage in each device is OK under worst case operational conditions, the following is recommended:

- Run all the actuators on the daisy chain cable at the same time. While all are running, check each value of AV:6 / 32794. These values should still be above 18V and no previously mentioned voltage level alarms should be initiated or indicated. If LEDs indicate an alarm state or a BACnet/Modbus alarm is initiated, or a value less than 18V is observed, then cabling should be reviewed.

- Check the values of AVO:0. This BACnet object holds 3 values: Average measured voltage, Maximum measured voltage and Minimum measured voltage. The most important value here is the Minimum measured voltage. It can tell you the lowest voltage that has been measured during operation of the actuator.

Mechanical manual operation

Manual operation is possible when NovoCon is not powered. Rotating knob to left will lift steam of valve UP and turning on right will push steam DOWN.

NovoCon® L, XL

Mechanical manual operation

The actuators have a knob & crank on the top of the housing which enables manual positioning of the actuator.

Use Mechanical manual operation only when the power is disconnected.

Mode

Electrical manual operation

The actuators have two buttons on the top of the housing that are used for electrical manual positioning (up or down) if the actuator is in Stand-By mode. First press the MODE button until the actuator goes to Stand-By mode (red LED is lit). By pressing the upper button the stem will be extended and by pressing the lower button the stem will be retracted.
