1. General description of MAGNA-LON

The LON-interface add on module for GRUNDFOS MAGNA connect a GRUNDFOS MAGNA

pump to a LON network. Via MAGNA-LON it is

possible to control the pump and get pump status.

Figure 1

MAGNA-LON is designed using a 3150 neuron chip, an FTT10 transceiver and a 32 Kbyte Flash memory, which makes updating of software possible.

The pump profile in this document is compliant with version 1.0 of “Pump Controller Object”, from LonMark organization.

The MAGNA-LON module has been developed according to LonMark Application Layer Interoperability Guidelines 3.3.

MAGNA-LON uses self documentation strings, which means an installation-tool can access the relevant information over the network, otherwise MAGNALON.XIF can be found on the same disk as this document.

2. Installation

When MAGNA-LON is delivered it is already configured. This means that when it is powered up the application program will start. The Flash memory will contain Firmware version 7.0, and application code. Furthermore the communication parameters will be present in the EEPROM memory of the neuron-chips. The customer will need to install the network and make the required bindings.

MAGNA-LON can be installed on a network in two different ways.

1. MAGNA-LON can be installed by pushing the SERVICE pin, which will cause the neuron-chip to transmit a unique 48 bit ID code to the network.

2. The unique ID code can also be found on the label situated on the side of the MAGNA-LON interface. The bar code is in Code 39 format. An additional label with the same unique code is supplied with the MAGNA-LON interface. This label can be attached to the building installation plan.

MAGNA has a yellow service LED that indicates various states of the interface. When is delivered it should only flash for a moment and then remain off. For further information see Echelon documentation.

5. Application example

Any HVAC unit can use the pump object, either as an actuator, where the pump speed is used to control the flow or pressure in the HVAC application, or the pump can be used as an intelligent device, which can maintain a constant pressure in the system. In both cases the pump can be monitored and manually controlled via the system.

In the following example the pump is used as an intelligent device which is running in PRESS_COMP control mode. This means the pump will automatically lower the pressure setpoint in proportion to the system flow. The unit turns the pump into minimum mode during nighttime via nviPumpOpMode and gets status for pump operation mode from nvoEffOpMode. The HVAC control unit uses nvoPumpStatus to retrieve status information from the pump. The controller can use this information to see pump faults and hardware overrides, and whether the pump is running or not.

The pump is attached to a manual stop button, which can be used to stop the pump. When the pump is stopped via nviPumpOvdStop the HVAC control unit is no longer able to control the pump via normal setpoint.

The example also shows a local control and monitor panel. Via this panel the pump fault status can be seen, as well as the pump flow and pressure. From this local panel it is possible to give the pump a pressure setpoint. This means the pump will keep a constant pressure, which will override the HVAC control unit.

The whole system is monitored via a main system.

The Pump Controller profile includes input network variables to manually override the operation of the pump. A valid value on any one of these input variables sets the pump into the override mode. The pump will not return to normal setpoint control until all manual override inputs are invalid. The priority of the various override inputs can be seen in Figure 3

Pump setpoint

network input sd_string(“@p|1”) SNVT_switch nviPumpSetpoint;

This input network variable provides start/stop control and a setpoint. The setpoint is given as a percentage of the effective maximum value (max. = 100%). The setpoint value can represent the pump speed, the pressure or the flow, depending on the Effective Operating Mode of the pump (nvoControlMode).

When using an external sensor, X can be calculated from the sensor range values.

The pump specific setpoint limits and the calculation of X for the different MAGNA pump types when not using an external sensor can be seen in the table below:

Pump type Setpoint Low

Limit

MAGNA 32120

MAGNA 40120

MAGNA 50-60

MAGNA 65-60

MAGNA 50120

MAGNA 65120

For example, if the setpoint limits (control mode DCM_PRESS_CONST or DCM_PRESS_COMP) are 10 kPa and 100 kPa, “X” can be calculated to be 10 %. This means that a setpoint value from 1% to 10% provides a setpoint of 10 kPa (0% stops the pump). 11% up to 100% provides a setpoint of 11 kPa up to 100 kPa.

1 m ≈ 10 kPa 10 m ≈ 100

The values of X for the unregulated mode are approximated values. A value of e.g. 30 % means that the lower speed limit of the pump is approx. 30 % of the value of the maximum speed.

The setpoint cannot be set in the control mode DCM_PRESS_AUTO. Control mode DCM_FLOW_CONST requires an external flow sensor.

Requested pump operating mode

network input sd_string(“@p|2”) SNVT_hvac_mode nviPumpOpMode;

This input network variable is typically used by a supervisory controller to override the pump controller operating mode. If a mode is requested that is not supported by the unit, the unit will treat it as an invalid value (treated as HVAC_NUL).

When the mode is HVAC_AUTO, the network-variable input, nviPumpSetpoint, defines the working setpoint of the pump. When the mode is HVAC_MRNG_WRMUP or HVACPRE_COOL, the pump operates at maximum capacity.

For energy saving at night, in the summer, or under low-load conditions, the mode HVAC_ECONOMY or HVAC_NIGHT_PURGE may be used. The pump operates in this mode at minimum capacity.

Pump capacity

network output sd_string(“@p|3”) SNVT_lev_percent nvoPumpCapacity;

This output network variable provides the actual pump capacity as a percentage of the effective maximum-setpoint value (pump specific setpoint high limit). A value of more than 100% means that the pump is providing a value that is higher than the highest possible setpoint.

Valid range

-163.840% .. 163.830% (0.005% or 50 ppm). The value 0x7FFF represents invalid data.

When transmitted

This value is transmitted immediately when its value has changed significantly. Additionally, this network variable will also be transmitted as a heartbeat output on a regular basis as specified by the Maximum Send Time <nciSndHrtBt> configuration property.

Effective operating mode

network output sd_string(“@p|4”) SNVT_hvac_mode nvoEffOpMode;

This output network variable provides the actual pump operating mode. The value of this network variable is the same as the value of the Requested Operating Mode (nviPumpOpMode) except when a different mode is selected by a local input on the pump, this could be STOP / MAX from push buttons or external STOP, in this case, the value will reflect this by setting the output to HVAC_OFF, and nvoPumpStatus.pump_ctrl.local_control (“Locally controlled pump”) will be set (“1”).

Effective device control mode

network output sd_string(“@p|5”) SNVT_dev_c_mode nvoControlMode;

This output network variable provides the actual control mode of the pump. The actual control mode is determined by nciControlMode, nviOvdSpeed, nviOvdPress, nviRemotePress or nviRemoteFlow.

Description

The setpoint of the pump will be interpreted as setpo int for the pump speed.

The setpoint value is a percentage of the maximum speed of the pum p.

The setpoint of the pump will be interpreted as setpo int for the pressure. The controller inside the pum p will change the pump speed so that the pressure is constant. The controlled pressure can be the pump pressure or can come from an external pressure sensor. The setpoint value is a percentage of the maximum poss ible constantpressure setpoint of the pump, or it is a percentage o f the maximum remote pressure-sensor value.

The setpoint of the pump will be interpreted as basic setpo int for the compensated-pressure mode (the black dot in the drawing). The controller inside the pump will autom atically lower the actual-pressure setpoint dependent on the flow (flow compensation-the dashed line in the drawing). The setpoint value is a percentage of the maximum poss ible compensatedpressure se tp oint of the pump.

The setpoint of the pump will be interpreted as setpo int for the pump flow. The controller inside the pum p will change the pump speed so that the flow will be co nstant. The controlled flow can be the flow thro ugh the pump or the flow signal c an com e from an external sensor. The setpoint value is a percentage of the maximum poss ible constant-flow setpoint of the pump, or it is a percentage of the maximum remote flowsensor value.

Pump override stop command

network input sd_string(“@p|6”) SNVT_switch nviPumpOvdStop;

This input network variable provides a manual override function to stop the pump, typically from a supervisory device. The value “OVDSTOP” stops the pump and has priority over the value of the Pump Setpoint nviPumpSetpoint and the two override setpoints nviOvdSpeed and nviOvdPress.

The manual override status of the pump controller is indicated in the output network variable nvoPumpOverride.

Default value is 0xFF (invalid value) in the state field. The value will be adopted at power-up.

Override setpoint for speed

network input sd_string(“@p|7”) SNVT_lev_percent nviOvdSpeed;

This input network variable provides an override request and a speed setpoint, typically from a supervisory device. This speed setpoint is given as a percentage of the maximum speed of the pump. When a valid value is received and the Pump Override Stop Command is not active, the present pump setpoint (nviPumpSetpoint or nviOvdPress) will be overridden and the pump will be controlled to the given speed setpoint. The pump then works in the DCM_SPEED_CONST mode.

Invalid values of all override setpoint inputs (nviOvdSpeed and nviOvdPress) and a normal status of the Pump Override Stop Command (nviPumpOvdStop) will set the pump back into the NORMAL mode. The manual override status of the pump controller is indicated in the nvoPumpOverride network variable. The control flow can be seen from Figure 3.

Valid range

-163.840% .. 163.830% (0.005% or 50 ppm). The value 0x7FFF represents invalid data that must be interpreted as “no override requested”.

A negative value will be interpreted as 0%, and the nvoPumpStatus.pump_ctrl.setpt_out_of_range(“Setpoint out of range”) will be set(“1”).

AValue of more than 100% will be interpreted as 100%, and the nvoPumpStatus.pump_ctrl.setpt_out_of_range(“Setpoint out of range”) will be set(“1”).

Default value is 0x7FFF (invalid value). The value will be adopted at power-up.

Override setpoint for pressure

network input sd_string(“@p|8”) SNVT_press nviOvdPress;

This input network variable provides an override request and a pressure setpoint, typically from a supervisory device. When a valid value is received and the Pump Override Stop Command is not active, the current pump setpoint (nviPumpSetpoint or nviOvdSpeed) will be overridden and the pump will be controlled to the given pressure setpoint. The pump then works in the DCM_PRESS_CONST mode.

Invalid values of all override setpoint inputs (nviOvdSpeed or nviOvdPress) and a normal status of the Pump Override Stop Command nviPumpOvdStop will set the pump back into the NORMAL mode. The manual override status of the pump controller is indicated in the nvoPumpOverride network variable. The control flow can be seen from Figure 3.

Valid range

-3,276.8 .. 3,276.7 kiloPascals (0.1 kPa). The value 0x7FFF represents invalid data that must be interpreted as “no override requested”.

A value below the Manufacturer-defined Setpoint Low–Limit will be saturated to this value, and the the nvoPumpStatus.pump_ctrl.setpt_out_of_range(“Setpoint out of range”) will be set(“1”).

A value above the Manufacturer-defined Setpoint High–Limit will be saturated to this value, and the the nvoPumpStatus.pump_ctrl.setpt_out_of_range(“Setpoint out of range”) will be set(“1”).

Default value

Default value is 0x7FFF (invalid value). The value will be adopted at power-up.

Remote Pressure Sensor Input

network input sd_string(“@p|10”) SNVT_press nviRemotePress;

The nviRemotePress network variable allows the use of a remote differential pressure sensor on the network as the feedback signal to the pump controller.

A valid value on the nviRemotePress network variable will disable the internal feedback signal of the pump controller and activate the remote sensor operating mode - forcing the pump to run in the constant pressure control mode. This is indicated by the nvoPumpStatus.pump_ctrl.remote_press

(“remote pressure sensor”) being set (“1”).

The nvoPumpCapacity output variable will indicate the value of the pressure signal from the sensor as a percentage of its maximum value. This makes it possible to compare the sensor value with the nviPumpSetpoint value.

The nvoPressure output variable always indicates the differential pressure across the pump flanges measured or estimated by the pump controller. This may help in analyzing the behavior of the system.

When using nviRemotePress, the pressure setpoint is given by nviPumpSetpoint. The ranging of both the setpoint and the feedback is given by the configuration properties: Remote Minimum and Maximum Pressure sensor Value (nciRemMinPress and nciRemMaxPress). These values are used in place of the manufacturer-defined setpoint limits.

If the nviRemotePress variable receives an invalid value or if the heartbeat (specified by nciRcvHrtBt) is missing, remote control is deactivated, and the pump controller will return to the control mode defined by nciControlMode.

Any valid value in the manual override inputs will take priority over the remote sensor control, and the pump controller will use the internal feedback signals.

Remote Flow Sensor Input

network input sd_string(“@p|11”) SNVT_flow_p nviRemoteFlow;

The nviRemoteFlow network variable allows the use of a remote flow sensor on the network as the feedback signal to the pump controller.

A valid value on the nviRemoteFlow network variable will disable the internal feedback signal of the pump controller and activate the remote-sensor operating mode - forcing the pump to run in the constant-flow control mode. This is indicated by the nvoPumpStatus.pump_ctrl.remote_flow (“remote flow sensor”) being set (“1”).

The nvoPumpCapacity output variable will indicate the value of the flow signal from the sensor as a percentage of its maximum value. This makes it possible to compare the sensor value with the nviPumpSetpoint value.

The nvoFlow output variable always indicates the flow through the pump measured or estimated by the pump controller. This may help in analyzing the behavior of the system.

When using nviRemoteFlow, the flow setpoint is given by nviPumpSetpoint. The ranging of both the setpoint and the feedback are given by the configuration properties: Remote Minimum and Maximum Flow value (nciRemMinFlow and nciRemMinFlow). These values are used in place of the

manufacturer-defined setpoint limits.

If the nviRemoteFlow variable receives an invalid value, or if the heartbeat (specified by nciRcvHrtBt) is missing, remote control is deactivated, and the pump controller will return to the control mode defined by nciControlMode.

Any valid value in the manual override inputs will take priority over the remote sensor control, and the pump controller will use the internal feedback signals.
