V2.0, July 2014 Operating and installation Instructions 2
This Installation guide contains the information necessary for safety. Installation and basic
running of the EC –Controller.
1. GENERAL SAFATEY
Danger!
Electric voltage on the device
EC-Drive must only be connected, instale, modified or repaired by a qualified
person! Incorrect mounting could cause material damage and risk of fatal
injury from electric shock! Domel is not responsible for any damage
caused by incorrect or bad circuit connection or by non-professional
installation!
Use fuses for power lines. Install all earth wires. Before operating check the
wires for short circuits. Use only cables that meet the specified installation
requirements for voltage, current, insulation material, load etc.
Warning!
Electric voltage!
Never open EC-Controller or parts of them when the main supply is
connecting. It can be extremely dangerous and could cause risk of fatal
injury from electric shock!
When is necessary to touch high voltages lines, disconnect the main supply
voltage and wait at least 5 minutes before servicing the drive.
Note!
It is the responsibility of the user or installer to ensure correct grounding and
protection in accordance with national and local standards.
1.1. Personal Safety
The [Start / Stop] input on the user interface panel of the EC drive does not disconnect the
drive from the AC line. Do not use it as a safety switch.
Do not remove the terminal lines for the motor and AC line supply while the EC drive is
connected to the AC line. Ensure that the AC line supply has been disconnected and wait
5 minutes before removing motor and AC lines.
The motor can be started by means of digital commands, bus commands, references or local
start command whenever the drive is connected to the AC line. Therefore, an unintended start
may occur anytime power is applied. Never service the drive or equipment when power is
applied to the drive.
Before installing and operating EC-controller please read this instruction carefully!

2.2. General installation
Correct and precise mounting of the controller is required to provide reliable and
carefree operation. The assembly should only be carried out by qualified persons,
because proper mounting, cooling and sealing of controller is needed. Mounting is
permitted only at prescribed places. All positions are allowed if conditions of solid
attachment and adequate cooling are fulfilled (to prevent overheating of electronic).
2.2.1. Mounting and sealing
We recommended horizontal (on table) or vertical (on wall, with cable glands pointing down)
attachment of the electronics. In horizontal installation we also recommend mounting on 2°-5°
angle with glands pointing down, for lighter leaking of surface liquids. Suitable sealing for top
cover and all glands should be provided at mounting (whether there are cables or not). Space
between other objects in controller must be at least 20 mm (from the closest corner of the
electronics). When attaching to metal surfaces, the M5x15 screw (according to DIN912) with
spring washers is recommended. When attaching to non-metal materials the M5x70 screw for
walls is recommend.
2.2.2. Cooling
For smooth operation it is necessary to provide the required thermal conditions. We
recommend force cooling, with speed 1.5 m/s of fresh cooler air, through the cooling ribs,

DOMEL EC –Controller Compacto
V2.0, July 2014 Operating and installation Instructions 4
although is possible to have cooling only with natural convection1. By cooling with natural
convection, the user should ensure at least 1 m of space over the highest cooling rib and also
controller may not be located in a enclosed place.
Note: Cooling exclusively with natural convection decreases lifetime of electronics.

3.2. Functions
Relay Error function: Electronics are equipped with isolated Relay error function via relay
250VAC/5A, NC(4), COM(5) and NO(6).
Relay error function is activated by:
AC input under voltage protection,
Blocked rotor detection,
Phase failure / Phase loss detection,
Overheating detection,
Controller Error detection –Internal error of electronics,
Phase Overcurrent detection.
The error state is automatically reset by removal all error caused.
AN1: Analogue input 1 –Electronics can be controlled by external analogue input voltage 0-
10 or 10-0 VDC to terminals (7) and (8). Electronics controls speed linear from RPM min to
RPM max. Maximal or minimal speed is defined as input voltage 9,5V ± 3%.
To start control the motor speed by AN1, connect Stop/Start terminal pins (18 and 19) and
FIRE mode terminal pins (16 and 17) together.
AN1 can be settable by holding registers 107, 108 and 109 (see Modbus parameters in
chapter 6). AN1Min parameter can be set to the desired minimum setpoint. AN1Max
parameter can be set to the desired maximum setpoint. AN1Min and AN1Max can be set from
0V to 10V. If AN1Max is smaller than AN1Min function is inverted (10V to 0V). By AN1Stop,
stop threshold voltage can be set. If AN1Stop is 0 threshold voltage is disabled and motor will
run with minimal settable RPM. By setting AN1Stop higher than 0 motor will not run up to
settable value.

DOMEL EC –Controller Compacto
V2.0, July 2014 Operating and installation Instructions 6
Example:
AN1min is set to 1V and AN1max is set to 9V. In the pictures above, controller works from
200RPM to 1500RPM. AN1 operates from 1V to 9V (AN1max > AN1min). AN1stop is set to
0V in picture 1, this means that AN1stop is disabled and motor will run with minimal RPM also
in case of AN1 and POT is 0V. In picture 2 AN1stop is set to 1V. this means that threshold
voltage is 1 and motor will not run below 1V.
AN1min is set to 9V and AN1max is set to 1V. In the pictures above, controller works from
200RPM to 1500RPM and AN1 operates inverted from 9V to 0V (AN1max < AN1min).
AN1stop is set to 10V in picture 3, this means that AN1stop is disabled and motor will run with
minimal RPM also in case of AN1 and POT is 10V. In picture 2 AN1stop is set to 9V. This
means that threshold voltage is 9V and motor will not run higher than 9V.
Hysteresis regulator will be preset in Domel on customer’s specifications.
Electrical parameters: Vinmax=12V, Zin=10kΩ, Resolution 10-bit, tolerance AN1±5%
Important: Wrong polarity at input AN1 could cause serious damage on the controller.

Set RPM via potentiometer: Electronics can be controlled by external potentiometer (4k7 to
47kΩ) connected to terminals (8=gnd), (9=input) and (10=+5V). If the direction of rotary
potentiometer is incorrect, change the wires on terminal (8) and (10).
Electrical parameters: Three-wire, Rpot=4k7-47kΩ, Zin=10kΩ
Power supply 5VDC/10mA: Electronics are equipped with 5VDC/10mA for power supply to
an external potentiometer. Power supplying other loads is not allowed. The 5 VDC supply is
galvanically isolated from the supply voltage, but has the same potential as the analogue and
digital inputs and outputs.
Electrical parameters: 5VDC +/- 5% (regulated); 10mA; Terminal number: 10.
Power supply 24VDC/40mA: Electronics are equipped with 24VDC/40mA power supply for
external sensor connected via AN2, or for small external fan for cooling controller. The 24
VDC supply is galvanically isolated from the supply voltage, but has the same potential as the
analogue and digital inputs and outputs.
Electrical parameters: 23VDC +/- 10% (not regulated); 50mA; Terminal number: 13, 16, 19.
AN2: Analogue input 2 –Electronics can be controlled by external analogue input signal AN2
for external sensor (temperature, CO2, smoke sensor, etc.).
Electrical parameters: Vinmax=12V, Zin=10kΩ, Resolution 10-bit
Important: Wrong polarity at input AN2 can cause serious damage on the controller.
PID Control:
Electronics are equipped with internal PID regulator via AN2. The PID Control uses the value
on the AN1 as Set Point value.
For additional PID control parameter setting see chapter 6 (Controller configuration).
Speed output: Electronics are equipped with an Open Collector speed output signal for
speed monitoring.
Speed output mode could be set as:
Frequency output f=1Hz/1RPM @ 25mA, (1Hz means 1RPM, max frequency is
determined by the max RPM)
PWM output –D=0%↔RPM=0, D=100%↔RPM=100%,
PWM output –10V / 1mA,
Current generator output 0-20 mA,
Current generator output 4-20 mA,
Voltage generator output 0-10 V/1 mA
Voltage generator output 2-10 V/1 mA
Voltage generator output 0-10 V/1 mA calculated regarding actual RPM with 5%
tolerance.

V2.0, July 2014 Operating and installation Instructions 8
Fire mode function: Electronics are equipped with Fire mode function. In this case
electronics runs as emergency controlled unit, (for example: extract the smoke from a burning
building), with disabled protections and functions.
In fire mode case:
Overheating protection - disable,
Under voltage protection - disable,
Start/Stop function –ignore,
Set RPM via AN1 or Potentiometer –ignore,
Set RPM via AN2 –ignore,
Phase overcurrent –disable,
Controller error detection - disable.
In Fire mode function electronics runs with Fire mode set parameters. These parameters
should be sets via Modbus registers. The function should be enabled by disconnect the
terminal pins (16) and (17). We recommended purpose switch. For disable the function
disconnect terminal pins (switch=ON).
Fire mode function can be also enabled via Modbus communication. For additional information
about activating fire function via Modbus, see the chapter 7.
Electrical parameters: Operating voltage = 24V, Zin=10kΩ
Note!
Fire mode function is useable only for protection in case of a burning
building, to extract the smoke from it. In normal condition the fire
mode function is not allow to be used. In this case Domel is not
responsible for damage to the controller caused by improper use.
Star/Stop function: Electronics are equipped with Start/Stop function. If the controller has all
conditions for running, the motor goes runs when the terminal pins (18) and (19), are
connected together.
Electrical parameters: Operating voltage = 24V, Zin=10kΩ

Modbus RTU 485 serial communication: Electronics are equipped with Modbus RTU 485
communication. To connect controllers into chain use only shielded cables.
Shielded cable for ground connection between controllers is necessary (terminal pin 14).
Speed control via MODBUS:
Parameter "Operation Mode" set to value 2 - Operation Mode = 2. The ON/OFF Switch
becomes inactive. To the Holding register at address 0 (Set_Point) write desired value of
speed in %.
For example:
Set_Point < 1000 (10,00 %) … Motor Stop
Set_Point = 1000 (10,00 %) … Motor Run at RPM_Min
1000 (10,00 %) < Set_Point <= 10000 (100,00 %) … Motor Runs at desired speed.
The motor speed is calculated by equation:

3.3. Protections
Thermal protection: The electronics are equipped with reducing thermal protection. This
function is a temperature limiter which reduces the output power, when temperature on the
controller rises over 75°C. In this case relay error function set output error.
In the event that the temperature of controller is still rising (over 105°C) the controller stops the
motor. When the temperature controller falls below 75°C, the motor automatically restarts.
Thermal protection is disabled in fire mode state.
Under and over voltage: The electronics are equipped with under and over voltage
protection. Electronics shutdown when the main voltage is not in the required range. See
mechanical and electrical specification.
Blocked rotor protection: The electronics are equipped with blocked rotor protection when
the rotor of motor is blocked or it is impossible to rotate it. Electronics automatically retries 25
restarts, than a manual restart by disconnecting the power supply is required.
Motor phase fail / lose: The electronics are equipped with motor phase fail protection in
event that one of phase motors is damage or missing. In this case electronics stops the motor
immediately. Protection is disabled in fire mode state.
Phase overcurrent protection: The electronics are equipped with phase overcurrent
protection when current through motor increases up to 10A. In this event electronics stops the
motor immediately and tries to makes automatically restart.
Rotor failed acceleration: The electronics sre equipped with rotor failed acceleration
protection when the rotor is damaged or is hard to rotate. Electronics automatically retries 25
restarts for every 1second. If the 25th restart is still unsuccessful, then manual restart by
disconnecting the power supply is required.
Note!
Heating the controller over the maximal temperature is not allowed.
Above 105°C electronics stops the motor (not in fire mode state), and
restarts it again when the temperature of controller falls below 75°C.
However, if the controller is overheating and motor was shutdown,
disconnect power supply (safety switch) and wait at least 20 minutes
before you service them. In case of overheating of controller, the
metal parts of them are very hot and could cause serious damage to
your skin.
If controller starts reducing output power during running, this may be
reason of overheating. In this case add small 24V/40mA fan on
controller or ensure air flow through the ribs. Fan can be supplied by
power from controller (chapter 4.2. –wiring diagram). Overheating
problem appears in the case of installation of the controller in the
space without air flow.

5. MODBUS RTU
The MODBUS RTU protocol is based on the built-in RS-485 (EIA-485) interface. RS-485 is a two-wire
bus-interface that allows multi-drop network topology i.e. nodes can be connected as a bus (daisy
chain), or via drop cables from a common trunk line.
Domel’s Compacto drives uses the two-wire system where the communication between master and
slave is half-duplex, i.e. it cannot transmit and receive at the same time. Each signal uses one twisted-
pair line —two wires twisted around themselves. The signal on one wire is ideally the exact opposite
of the signal on the second wire. Since RS-485 is a multipoint communication system, all devices are
connected to the single twisted-pair cable.
The Modbus RTU uses master/slave architecture, where each slave device has its unique address
and responds only to packets addressed to this device. The packets are generated by the master
(Controller), which periodically polls all connected slave devices. Data travels over the single line in
both directions.
One or more EC drives can be connected to a control (or master) using the RS-485 standardized
interface. Maximal number of Compacto EC Drives connected to the network is 32. If more than one
frequency converter is connected to a master, use parallel connections. Terminal 14 is connected to
the signal TX+, RX+, while terminal 15 is connected to the signal TX-,RX-.

To connect PC and DOMEL Compacto Drive over serial line (MODBUS) RS-232/USB to RS-485
Converter is needed. We recommend ADAM-4561 converter. To attach the ADAM-4561 to a PC, you
do not need to power down your PC. The power for the ADAM-4561 converter is derived from the USB
port, so there are no power adapters to deal with.
The ADAM-4561 device driver can be used in combination with Windows 2000/XP/Vista/7 (32 & 64-
