General information

The Biral series, ModulA consists of a complete range of circulation pumps with integrated frequency converter, which enable independent or controlled adaptation of output to the actual requirement of each system. Therefore, in many systems, energy consumption will be reduced and the control behaviour of the system improved. Besides this, current noise from control cabinets can be reduced effectively. All necessary settings can be adjusted using the control panel for the pump.

Purpose
Biral circulation pumps of the ModulA series are intended for the circulation of liquids in the following systems:

• ModulA… RED in heating units
• ModulA… BLUE in domestic hot water systems

The pumps can also be used in the following systems:

• Geothermal heat pumps
• Thermal solar equipment

The pumps are suitable for use in systems with variable and constant delivery volumes.

Requirements of the delivery medium
The pump is suitable for delivery of pure, thin, non-explosive and non- aggressive media without fixed or long-fibred elements, which do not affect the pump either mechanically or chemically.

Heating water:
Requirements according to current standards that apply to water quality in heating systems: (e.g. VDI 2035)

Glykol:
The pump can be used for delivering water-glycol mixes. Maximum permissible viscosity: 50 mm²/s (cSt). This corresponds to a water-ethylene-glycol mix with a glycol content of around 50% at –10°C.
The pump is controlled via an output-limiting function that protects against overload. The delivery of glycol mixes affects the MAX characteristic curve because the delivery capacity is reduced accordingly, based on the glycol content and temperature of the media. So that the effect of the glycol is not reduced, temperatures above the nominal temperature given for the medium should be avoided. Generally, the operating duration with high media temperatures should be minimised.
Before adding the glycol mix, it is vital that the system is cleaned and rinsed. To avoid corrosion or precipitations, the glycol mix should be checked regularly and changed if necessary. If the glycol mix has to be further thinned, the specifications from the glycol manufacturer should be adhered to.

For the delivery of a liquid with density that differs from water and/or kinematic viscosity, the delivery output is reduced.

Domestic hot water:
Permissible water hardness:
max. 35 °fH (20 °dH) (water temperature below 65 °C)
max. 25 °fH (14 °dH) (water temperature below 85 °C)

To counter the risk of lime deposits, for domestic hot water systems we recommend: Hardness level max. 25 °fH (14 °dH) Medium temperature <65 °C

Warning
The pump may not be used to deliver combustible media such as diesel and fuel.
Warning
The pump may not be used to deliver aggressive liquids such as acids or seawater.

Operating conditions

Medium temperature:

• ModulA… RED +15 °C to +110 °C
• ModulA… BLUE +15 °C to +85 °C (recommended for domestic hot water systems: max 65 °C)

Operating pressure:
The maximum permissible operating pressure is indicated on the nameplate. (6 bar, 10 bar or 16 bar) Minimum operating pressure at the pump intake ports (intake pressure) at 500 m above sea level:

Per ±100 m height ± 0.01 bar

In the dual pump operation the supply pressure required must be increased by 0.1 bar in line with the values in the table.

Ambient temperature:
0 °C to 40 °C

Non-return valve

If a non-return valve is fitted, the pump must be adjusted (see 7.2), so that the discharge pressure of the pump exceeds the closing pressure of the valve at all times.
This must be adhered to in particular for the proportional pressure control (reduced delivery height for decreasing delivery flow).

Protection from the effects of frost

Where there is a risk of frost during downtime periods, measures required to avoid frost damage must be taken.

Heat insulation (ModulA… RED, ModulA… BLUE)

Heat is lost via the pump casing and pipes. These heat losses should be limited to a minimum.

Heat losses can be reduced by insulating the pump casing and pipes.

For ModulA… RED, heat insulation shells are included in the delivery.

Heat insulation shells can only be supplied for single pumps

1. Never cover the frequency converter or the control panel with insulation.
2. Keep the drainage outlet at the motor free..

Flow direction

The arrow on the pump casing indicates the flow direction.

Installation

General notes
ModulA is only intended for installation indoors. The pumps must be mounted voltage-free so that no energy can be transferred from the pipes to the pump casing. The pumps can be installed directly in the pipe, provided the pipes are designed for the weight of the pump.
Installation is only possible after completion of all welding and soldering work on the system. Avoid drops of water on the pump motor, especially the frequency converter.

Warning
The local regulations for the lifting and carrying of loads must be adhered to. The weight of the pump is given on the packaging.

Flushing heating equipment (for extended pump)
To avoid unwanted interruptions to operations and non-running of the pump after longer periods of inactivity, we recommend thoroughly flushing out the equipment following the new installation or adaptation of heating and refilling.
The equipment must correspond with the latest technology. (Placement of expansion vessel or safety flow).

Installation
Install only after completion of all welding or soldering work on the equipment. Water drops should be avoided on the pump motor, especially on the electronics. The pump casing should be installed voltage-free in the equipment.

6. Carefully push in the electronics:
   «A»: connector plug
   «B»: Holder

7. Put in three Torx screws and tighten (8Nm)

If the motor is lifted from the pump casing, care should be taken when replacing it due to the movable ring otherwise the impeller may be damaged.

1. Ensure correct positioning of the O-ring.
2. The ring in the pump casing must be centred again before fitting the motor.
3. Fit the pump head carefully so that the motor lies flat on the pump casing without any gaps.
4. Insert four hexagon socket bolts and tighten the screws. (18Nm)

Install the pump in the unit

1. Close the shut-off valves and ensure that the system is without pressure when fitting the pump.
2. Install the pump in the pipe with seals.

Warning
Risk of injury from escaping steam!

Flange connection
The pump flanges are drilled with mounting holes, PN6/PN10/PN16. For safe screwing of the flanges, the shims supplied (B) must be fitted.

Safety elements (e.g. snap rings) are not permissible. For PN 10/16, special seals and screws must be used.

Warning
Use the relevant screws for nominal pressure PN.

• for M 16 <95 Nm

Installation of combined flange with combined flange is not permissible.

After installation is completed, put on the heat insulation shells and secure with cable bands.

Electrical connection

Electrical connection should be carried out in accordance with the local regulations.
It is vital to ensure that the voltage and frequency indicated on the nameplate are compatible with the mains supply available.

Warning
Before carrying out any electrical connection work, the voltage supply must be switched off.
The pump must be connected to an external network switch with a contact opening on all poles of minimum 3 mm.
The protection against indirect contact can be achieved by earthing or potential equalisation.

The pump does not require any external motor protection. The motor has integrated over-temperature protection, which offers safeguarding against overloading that appears slowly and against blocking according to IEC 34-11: TP 211.

Additional safety features
If the pump is connected to an electrical installation, which has an FI circuit breaker for additional protection, the FI circuit breaker must trigger with a pulsing direct current component if earthing fault currents arise.
The FI circuit breaker must be marked with the following symbol:

IEC 605
| Highly sensitive residual current circuit breaker type B in accordance with IEC 605

Supply voltage
1×230V ±10%, 50/60 Hz, PE
The voltage tolerances are set for equalising voltage fluctuations on the mains. They are not for operating pumps with voltages other than those shown on the nameplate.

With direct mains connection, the pump may not be switched on and off at the mains more than four times an hour. If the pump is switched on directly via the mains, it only starts after a 5-second delay

Connection of the power supply
The pump must be protected on-site and must be connected to an external mains switch. All cables used must have a heat resistance of up to 85 °C. They must not be in contact with the pipe or the pump and motor casing. All cables must be connected in accordance with EN 60204-1 and EN 50174-2: 2000. The electrical connection must be made as indicated on the nameplate.

Switch settings

Switch 1, Fault or operating signal (switchable)
The pump has a signal relay with potential-free changeover contact for external fault notification.
The signal relay can be switched over to operation notification via switch 1.

Switch 2, external OFF or external ON (switchable)

The digital input can be used for external ON/OFF switching of the pump. Using switch 2, it is possible to switch over from external OFF to external ON.

Note: If no external ON/OFF switch is connected, the pump runs if switch 2 is in the OFF position and no bridge is plugged in at terminals 11 or 10. This is the factory setting.

Switch 3, power limit (can be activated)
The power limit (volume flow limit ) can be activated in the pump.

The pre-set maximum volume flow is at the end of characteristic curve 3 (proportional pressure).
The volume flow limit can be set from 25 … 90 % via Biral Remote.

Start-up

General

Before start-up, it is vital that the unit is filled with the delivery medium and ventilated. Close to the inlet nozzles of the pump, it should also be the required minimum intake pressure. The system can be ventilated via the pump. The pump itself is self-ventilating.

Operational control
After switching on the power supply the pump must start up independently: the Biral impeller turns and flashes green.

The pump runs according to basic settings (see paragraph 7.10)

Settings

Warning
There is a risk of burning! For high media temperatures the pump may become so hot that only the keys may be touched.

Types of control

Operating key

Controlled operation: proportional pressure (pp) may be used in the following systems:

• Dual pipe systems with thermal valves and
• long stretches of pipe
• valves with large working area
• high pressure loss
• Primary circulation pumps with high pressure loss

Controlled operation: constant pressure (cp)
may be used in the following systems:

• Dual pipe systems with thermal valves and
• Delivery height >2m
• Natural circulation
• With very low pressure loss
• Primary circulation pumps in systems with low pressure loss
• Floor heating with thermostatic valves
• Single pipe heating

Non-controlled operation: constant speed (cs)
The operating point can be optimally set by adjusting the speed (key A2) optimal. May be used for systems with constant volume flow: air-conditioning applications, heat pumps and boiler feed pumps, etc.

Delivery height (A2)

The target value of the pump can be set by pressing the key or .

Example:
LED 3 lights up (green): characteristic curve 3
LED 3 and 4 light up (green): characteristic curve between 3 and 4

If any radiators are not sufficiently hot, set the next highest characteristic line.
