BC3150Blowdown Controller

DescriptionThe BC3150 is a blowdown controller for steam boilers. It controls TDS (total dissolved solids – salts in solution) by opening and closing a blowdown valve. It works in conjunction with a Spirax Sarco conductivity sensor, a boiler blowdown valve or condensate dump valve.The product can be panel, DIN rail or chassis mounted and powered by a 99 – 264 Vac mains supply.The front panel has a 3 digit LCD and a five-button keypad.The product has no battery. The programmed settings are held in non-volatile memory (Flash) and are written to after changing a parameter and pressing the OK key.

Principal features:

- Blowdown controller with temperature compensation.

- Type approved as a TDS limiter and controller.

- Works with CP10, CP30 or CP32 conductivity probes.

- Wide range: 1-9990 µS/cm or ppm – (x1, x 10, x 100 x 1000).

- LCD display with direct probe condition indicator.

- Infrared communications.

ApprovalsThis product complies with the Electromagnetic Compatibility Directive 2004 / 108 / EC and all its requirements.

The BC3150 is suitable for Class A Environments (e.g. industrial). A fully detailed EMC assessment has been made and has the reference number UK Supply BH BC3150 2008.

The BC3150 complies with the Low Voltage Directive by meeting the standards of:

- EN 61010-1:2001 safety requirements for electrical equipment for measurement, control, and laboratory use.

The BC3150 has been type-tested as a TDS controller and limiter by meeting the standard:

- Vd TÜV Equipment for Water Control 100 (07.2006).

- The BC3150 is UL listed (open).

FunctionAll ranges and operating parameters are selected using the software menu.

Commissioning is carried out using the two lower buttons.Once fully commissioned, the TDS value is displayed in μS/cm (or ppm if selected).

If the water conductivity exceeds the Set Point level, the TDS value shown on the display will alternate with 'bld', and the valve relay will be energised until the conductivity drops below 5% of full scale (FS) below the set point.

If the water conductivity exceeds the alarm level, the TDS value will alternate with 'AL' , and the valve relay will be energised until the conductivity drops 3% (FS) below the alarm level.

If the system is carrying out a purge, The TDS value will alternate with 'Pur', and the valve relay will be energised until the conductivity drops 5% (FS) below the set point.

InputsThe BC3150 can accept a signal from a Spirax Sarco conductivity probe (CP10, CP30, or CP32).

A Pt100 temperature sensor may be connected to provide temperature compensation (2% / °C). This is recommended if the boiler is working at varying pressures, or for other applications, such as condensate monitoring or coil boilers, where the temperature may vary. If a Pt100 is not fitted, the product uses a default temperature of 184°C (10 bar g). OutputsPulsed output - For smaller boilers where the capacity of the blowdown valve is relatively high compared to the boiler size, the blowdown may be set to pulsed, rather than continuous output, opening for 10 seconds, and closing for 20 seconds. This slows the rate at which the boiler water is removed so that the level is not unduly affected, avoiding the risk of triggering a low water alarm.

Other featuresTo prevent unwanted or inadvertent changes being made, all commissioning parameters are protected with a pass code. The BC3150 can communicate via an infrared link between adjacent controllers.

This feature enables the parameters of this product (OEM) to be passed to a product fitted with RS485 (user).

The BC3150 is always an IR slave – No set-up or adjustment is needed.

An isolated 4 - 20 mA output is provided as standard, and may be used for remote display of the TDS level or as an output to a computerised management system.

TI-P403-90-US 07.10

DescriptionThe BC3250 is a blowdown controller for steam boilers. It controls TDS (total dissolved solids - salts in solution) by opening and closing a blowdown valve.

It also has a timer that controls a bottom blowdown valve, to remove precipitated solids from the bottom of the boiler.

The product works in conjunction with a Spirax Sarco conductivity sensor, a boiler blowdown valve and, for condensate contamination detection, a dump valve.

It can operate on a supply voltage of between 99 - 264 Vac.

The front panel has an LCD graphics display and five-button keypad to select, view, and change functions.

In run mode (standard setting) the display is divided into three sections:i) Process variable and control parameters.ii) Information line, displays the various control states and process

units. iii) Three bar graphs, which show a percentage of full scale of: - PV Process Variable highest and lowest recorded value. - SP Set Point and hysteresis point.

- AL High Alarm and hysteresis point.

An additional filter can be selected to increase the damping effect where the probe is fitted directly in the boiler. This avoids over-frequent valve operation.

A Trend graph screen display appears if the right or left button is pressed in run mode - This displays a record of the variation in TDS over a set time.

The BC3250 can be used on a condensate contamination system. Please note that it will not detect contaminants that do not change the conductivity, e.g. oils, fats, or sugars.

The blowdown may be set to pulsed, rather than continuous output, opening for 10 seconds, and closing for 20 seconds. This avoids the risk of triggering a low water alarm in smaller boilers.

An isolated 0 - 20 or 4 - 20 mA output is provided for remote display of the TDS level or as an output to a management system.

If a switch box is fitted to the bottom blowdown valve actuator, an alarm can be configured to indicate if the bottom blowdown valve fails to close or to lift off its seat.

The BC3250 can communicate via an infrared link between adjacent controllers. It can be designated as either a master unit or a slave unit.

The unit can be panel, DIN rail or chassis mounted.

Principal features: Blowdown controller with bottom blowdown timer.- Multi-voltage 99 Vac – 264 Vac.- Display in µS/cm or ppm. - LCD graphics display of PV and sequential trend graph.- Filter for turbulent conditions.- Infrared communications.- Diagnostic / test facility.- 0/4 - 20 mA output.- EIA 485/Modbus communications.

ApprovalsThis product complies with the Electromagnetic Compatibility Directive 2004 / 108 / EC and all its requirements.

The BC3250 is suitable for Class A Environments (e.g. industrial). A fully detailed EMC assessment has been made and has the reference number UK Supply BH BC3250 2008.

The BC3250 complies with the Low Voltage Directive by meeting the standards of:- EN 61010-1:2001 safety requirements for electrical equipment for

measurement, control, and laboratory use.

The BC3250 has been type-tested as a TDS controller and limiter by meeting the standard:- Vd TÜV requirements for TDS control and limiting devices, Water Level 100 (07.2006).- UL listed (open).

FunctionInputsThe BC3250 can accept a signal from a Spirax Sarco CP10, CP30 or CP32 conductivity probe, and a Pt100 temperature sensor.

Function / outputsIf the water conductivity exceeds the Set Point, the valve relay will be energised until the conductivity drops below the Set Point. If the water conductivity exceeds the alarm level, the alarm relay will be de-energised until the conductivity drops below the alarm level.

Other features:- Test function.- Direct display of probe factor. - Commissioning parameters protected with a pass code.

3/4" BCV 30 Blowdown Control Valve

TI-9-305-US 11.11

DescriptionThe Spirax Sarco BCV30 is an electrohydraulically actuated control valve for the blowdown of steam boilers or other high pressure drop, low flowrate applications.It is generally used with a blowdown controller as part of an auto-matic TDS control system.The flowrate is adjusted by limiting the spindle stroke to regulate the number of orifices that are uncovered.The valve, which is supplied adjusted to its low flowrate setting of .4’’ stroke, is especially designed to minimize seat erosion and ensure consistent tight shut-off.It can be adjusted to .6’’ stroke for medium flowrates, or to .8’’ stroke for high flowrates, by repositioning the internal cam. A valve position indicator is provided.The valve can be opened manually by turning the actuator hand-wheel clockwise.A 1/4’’ BSP tapping is provided for a sample cooler.Full installation, adjustment and maintenance information is pro-vided with the valve.

Sizes and Pipe Connections3/4’’ Flanged ANSI 300

OperationThe valve is spring loaded to the closed position.When power is applied to the actuator the valve opens to the posi-tion set by the internal limit switch.

¾" BCV31Blowdown Control Valve

DescriptionThe Spirax Sarco BCV31 is a pneumatically operated control valve for the blowdown of steam boilers. It is normally used with a control-ler as part of an automatic TDS control system, though it can also be used for other high pressure drop, low flowrate applications.The flowrate is adjusted by limiting the spindle stroke to regulate the number of orifices that are uncovered.The valve, which is specially designed to minimise seat erosion and ensure consistent tight shut-off, is supplied adjusted to its low flowrate setting of 10 mm.It can be adjusted to give 15 mm stroke for medium flowrates, or to 20 mm stroke for high flowrates. The actuator has a mechanical stroke indicator and incorporates a rolling diaphragm.A ¼" NPT plug at the base of the valve may be removed to allow a sample cooler to be fitted (available from Spirax Sarco).The BCV31 requires a regulated and filtered air supply (¼" NPT), which should be free of oil and water, and a solenoid valve, (avail-able from Spirax Sarco).

Operation:The valve is spring loaded to the closed position (spring retract), and is also held closed by the boiler pressure. When the solenoid valve opens, air is admitted to the actuator causing the valve to open to the selected stroke.

Sizes and pipe connections¾" ANSI Class 300Note: All certification /inspection requirements must be stated at the time of order placement.
