SCALA1 Module Integration Guide Version 1.0.1

Introduction

The module allows wireless control of the SCALA1 host product

Purpose

The module is the user interface (UI) of the host product via Bluetooth Low Energy (BLE). The

module communicated with a smartphone with a “Grundfos Go” app installed.

Use conditions

The SCALA1 module may only be used inside a Grundfos host product.

The host product must provide an IP X4 or better enclosure to keep ingress of water away from

the module.

Module Description

The module is self-contained with buffered in- and output, regulated voltage, onboard integrated

antenna, RF shielding of the radio parts (except antenna).

• Voltage supply is: 115 Vac, 60 Hz

o Internally regulated Vss: 3 – 8 Vdc, nominel 5 Vdc

• Current draw Vss is: 250 mA max, 60 mA nominel

• Temperature range is: 0 – 55 degrees Celcius

• Communication, wired RS-485 115 kBaud

• Radio air interface BLE – Bluetooth Low Energy

o Frequency Band: 2.4 GHz ISM

o Frequency of Operation:2400 – 2483.5 MHz

o Antenna Gain: 0 dBi (Integrated F-type antenna)

o Type of Modulation: GFSK

o Emission Designation : F1D / G1D

o Transmit Power (EIRP): 5 ±0.1 dBm

o Bandwidth: 1 MHz

o Channel Spacing: 2 MHz

o Bluetooth Version: 4.2

The module complies to all 8 requirements of the FCC modular approval rules:

• Requirement

• Compliance:

Yes or No along with a justification

• The radio elements must have the

radio frequency circuitry shielded.

Physical components and tuning

capacitor(s) may be located

external to the shield, but must be

on the module assembly

• Yes.

• Physical shield box covers all RF parts

except the F-antenna.

• Peripheral interface parts are not

shielded

• The module must have buffered

modulation/data inputs to ensure

that the device will comply with

Part 15 requirements with any type

of input signal

• Yes.

• The transceiver has buffered data

input / output ports.

Grundfos Holding A/S

SCALA1 Module Integration Guide Version 1.0.1

• The module must contain power

supply regulation on the module

• Yes.

•

Module contains a voltage regulation

• The module must contain a

permanently attached antenna, or

contain a unique antenna

connector, and be marketed and

operated only with specific

antenna(s), per Sections 15.203,

15.204(b), 15.204(c), 15.212(a),

2.929(b)

• Yes.

• External to the shield, the Printed

Circuit Board has a “F-type” antenna,

solderconnected to the matching

network

• The module must demonstrate

compliance in a stand-alone

configuration

• Yes.

• Module is to be part of a host product.

It is listed in standalone configuration,

with only power and data (USB) supply

leads

• The module must be labelled with

its permanently affixed FCC ID

label, or use an electronic display

(See KDB Publication 784748 about

labelling requirements)

• Yes.

• Label is affixed to RF shield box

• The module must comply with all

specific rules applicable to the

transmitter including all the

conditions provided in the

integration instructions by the

grantee

• Yes.

•

• The module must comply with RF

exposure requirements

• Yes.

• Bluetooth module is Bluetooth Low

Energy (BTLE) and will not have enough

power to exceed SAR limits. It is also to

be mounted >20 cm from any

bodyparts.

Module Integration

Host product exploded view

Module placement in Host product

The module must be placed in a location where there are no metal or conductive parts between

the radio module and the user.

Grundfos Holding A/S

SCALA1 Module Integration Guide Version 1.0.1

Antenna placement in Host product

The module has a PCB trace “F” antenna with 0 dBi gain in the max. direction.

The antenna is located outside the RF shield of the module and must be kept free of conductive

parts and wires.

The PCB antenna is located under the silkscreen text “BLE ANT” on the PCB component side and is

visible on the non-component side of the module PCB

GND considerations in Host product

The module antenna uses the GND plane of the module and is not dependant of the host GND

plane construction.

RF exposure considerations of Host product

Because the radiated power (EIRP) is 0 dBm and only the integrated antenna can be used, the

host product cannot radiate dangerous amounts of RF energy that can be absorbed by the user.

The host is “mobile” and must be more than 20 cm from the users head and body at all times

Other considerations

This module may not be co-located with other transmitters or transmit simultaneously with radios

within 20 cm.

Grundfos Holding A/S

SCALA1 Module Integration Guide Version 1.0.1

Host manual considerations

The host manual must contain instructions that the user may not be closer than 20 cm from the

RF parts of the module.
