5. INSTALLATION
The DSS2 ECO-1.5 speed controller should be mounted horizontally on
the surface of a wall or in a control cabinet (in that case the exchange
of air or cooling should be made).
The power cord must be connected by non-shielded 3x1 mm² cable.
Steering signal must be connected by shielded cable:
2x0,5 mm² – for steering by DEN 20, DEN30, PLC etc.
3x0,5 mm² – for steering by DEN 11.
The cable shield should be connected to G0 terminal.
The motor must be connected by screened 3x1 mm² cable. The shield
must be connected to the PE terminal and the motor housing.
Cables must be completed with sleeves.
To connect the wires unscrew the four screws that secure the lid and
then perform the connection according to the diagram in Figure 4
After connections are made, close the cover and switch the power
supply on.
The capacitor should be connected outside of the regulator.
The controller does not have an input for TK fan protection.
WARNING!
It is essential to disconnect the power before installing the product.
It is forbidden to run the controller with an open case.
Installation should be performed by qualified personnel or the service.
Non-authorised changes lead to warranty loss.
It is forbidden to disconnect the load (the motor) while operating.
By doing so you may damage the controller!
If the T2.5 fuse blows it is recommended to try to run a regulator with
an inserted F400 fuse and the motor disconnected. If the fuse does
not blow - insert the T2.5 fuse and start the controller. If the fuse
blows again, please contact the manufacturer.

6. OPERATION
6.1. Operating mode selection
On the speed controller’s board there is a JT switch by which you can
choose the control type - with keypad (KB mode) or 0-10V signal (A mode).
Switching must be done in OFF state in accordance with the Fig. 4.
6.2. Keypad based control (KB mode)
The DSS2 ECO-1.5_P control keyboard (Fig. 3) is placed on the facade.
It allows using all the features of the device without the need for external
controllers and to monitoring the current state of work.
Fig. 3 DSS2 ECO-1,5_P control keypad.
(1) – ON/OFF button, (2) – DOWN button, (3) – UP button
(4) – LED indicator bar, (5) – work and alarm LED indicator
To switch the regulator on, set the main switch located on the right side of
the controller to I position. Then, by pressing the ON/OFF button, the
regulator comes out of sleep mode and you can change the output voltage
with the DOWN and UP buttons. The steering level is indicated by a LED
indicator bar consisting of 8 LEDs.
Pressing the ON/OFF button again stops the controller and turns it into
sleep mode. The fan slows down smoothly, which is signalized by blinking
of a LED indicator bar.
During the operation mode the green LED RUN is lit constantly and
indicates proper operation. In sleep mode this LED flashes once every
three seconds to indicate that the controller is connected to the power
supply.
WARNING! Sleep mode set on the keypad does not disconnect power from
the motor! For galvanic isolation of the motor from the power supply, use
the main switch on the case or disconnect the controller from the power
source.
By pressing the ON/OFF button again the speed regulator returns to work
with the previously set speed level.
6.3. Analog 0-10V signal based control (A mode)
0-10V analog input allows setting the fan speed remotely. It is possible to
connect regulators into systems controlled by a single signal set by an
external controller.
The regulator is equipped with its own source of +10 VDC voltage supply
which can be used to connect the DEN 11 controller or control
potentiometer.
In DSS2 ECO-1.5_P version the signalling of operation, alarm and speed
level is done through LEDs in the s ame way as for the control by the
keypad. ON/OFF button allows you to stop and resume work. Buttons
DOWN and UP do not affect the operation of the device in A mode.
In DSS2 ECO-1.5 version the power is indicated by the green D1G LED
placed on the electronic board.
6.4. Overheating alarm of the regulator
The red LED ALARM indicates a state of regulator overheating risk.
Possible LED states:
The LED is not lit – proper regulator operation.
The LED is blinking – regulator overheating state – regulator
temperature exceeds 60oC. The regulator reduces the engine speed to
a maximum of 30%. This continues until cooling down. If this
condition lasts longer than 10 minutes, the controller switches to a
critical alarm state.
The LED is lit continuously – critical alarm state – regulator
temperature exceeds 70oC. Regulator speed drops to 0% – the fan is
not working. This condition continues until cooling down.
Alarms are shown only on the keypad. The regulator without a keypad
does not have a LED alarm signalling.
6.5. PT1G potentiometer
In case of using the controller without a keypad it is not possible to
configure the settings in the menu. For this reason, there is a PT1
potentiometer installed on the electronic circuit board. It allows adjusting
the Dmin parameter (see the description of the service mode) in the range
from 0 to 40%.
It should be noted that the overriding value is the value set in the service
menu. The potentiometer state is read only when the parameter Dmin
in service menu is set to 0%. If this value is non-zero, the potentiometer
settings will be ignored.
6.6. Additional information
In KB mode (keypad controlled) after power disconnection during
operation and then connected again, the regulator will start operation
with the last memorized fan speed.
In KB mode (keypad controlled) after setting the regulator into sleep
mode with ON/OFF button, it will remain in the sleep mode after
disconnecting and re-powering again.
In 0-10V mode (A mode) after setting the regulator into sleep mode
with ON/OFF button, after disconnecting and re-powering again it will
begin work based on current 0-10V analog signal level.
7. SERVICE MODE
Service mode allows adjusting the parameters of the regulator to the
individual user needs. The following parameters can be modified:
minimum output level, maximum output level, minimum analog 0-10V
value, maximum analog 0-10V value. It is also possible to restore the
factory settings.

7.1. Entering and navigation in the service mode
To enter the s ervice mode the regulator must be in operation mode (the
LED "RUN" is lit). Simultaneously press and hold the UP and DOWN
buttons for 4 seconds. The regulator will reduce the fan speed to zero and
then switch to the serv ice mode. The moment of entering the servi ce
mode is indicated by a half second long blink of the LED line.
After entering the service mode, the 1st menu level is selected –
parameter selection mode. The green RUN LED flashes slowly. DOWN and
UP buttons allow selecting the parameter to edit. The currently selected
parameter is indicated by the corresponding LED in LED line (from No. 1 to
No. 8). After making your selection by pressing the ON/OFF button, the
regulator goes into the 2nd menu level – parameter edit mode. This state
is indicated by fast blinking of the green RUN LED.
The flashing LED indicates the parameter number which is currently
edited. The number of LED’s lit in the LED line indicates the parameter’s
current value on the scale of 0-100%.
To edit the parameter’s value use DOWN and UP buttons (except for Amin
and Amax settings). To accept the changes, press the ON/OFF button to
make the changes and return to the 1st menu level.
After editing, to save the set values and to leave the service mode, press
simultaneously DOWN and UP buttons in the 1st menu level. The LED line
will blink twice and the regulator will turn off. After turning the regulator
on again, it will work according to the modified parameters.
WARNING! Any changes made to the parameters are stored in EEPROM
only after exit the service mode using keys DOWN and UP in the manner
described above.
Editable parameter list:
D mode – keypad based control:

3. Amin – the minimum analog 0-10V signal level
4. Amax – the maximum analog 0-10V signal level
...
8. Restoring factory default settings
7.2. Parameter description and editing
LED No. 1, Parameter: Dmin
Adjusting the minimum regulator output voltage corresponding to
minimum steering level.
The default value is 0%. Switching on of every subsequent LED results in a
5% increase of Dmin. The maximum value is 40% with 8 LEDs lit.
WARNING! Dmin parameter allows you to change the minimum value of
the output voltage during operation of the regulator (steering level higher
than zero). At a setting of 0% steering level the regulator always switches
the motor off.
LED No. 2, Parameter: Dmax
Adjusting the maximum regulator output voltage corresponding to the
maximum steering level.
The default value is 100%. Switching off of every subsequent LED results in
a 5% decrease of Dmax. The minimum value is 60% with 8 LEDs off.
LED No. 3, Parameter: Amin
Adjusting minimum voltage of 0-10V signal results in setting the
minimum output voltage (activation threshold).
The parameter can be adjusted in the range of 0 – 4 VDC.
The factory default setting is 0.3 V.
To set the parameter’s value – see Amax parameter description.
LED No. 4, Parameter: Amax
Adjusting maximum voltage of 0 -10V signal resulting in setting the
maximum output voltage.
The parameter can be adjusted in the range of 6 – 10 VDC.
The factory default setting is 10 V.
After entering the edit mode of Amin or Amax parameter the "RUN" LED
and LED 3 or 4 blinks. The LED line indicates the current voltage applied to
the analog input on the scale 0 - 4 VDC for Amin parameter and 6 - 10 VDC
for the Amax parameter.
Parameter changes are made not by editing but by saving the current
voltage level applied to the analog input of the regulator.
For this purpose, in Amin/Amax edit mode you should set control voltage
at the desired value to the DSS2 ECO-1.5 analog 0-10V input (AI, G0
connectors), and then confirm selection by pressing the ON/OFF button.
The current level of the control voltage is stored and used as the new
value of Amin or Amax.
WARNING! By entering and exiting Amin or Amax parameter editing mode
without setting appropriate control input voltage level the regulator will
remember no voltage level (i.e. 0 V) as the value of a A min or 6.0 V as the
value of Amax. This may result in incorrect operation o f the regulator in
A mode.
In this case set the desired voltage A min/Amax levels again correctly
or restore the factory default settings.

LED No. 8, Restoring factory default settings
To restore the factory default settings, in the 1st service menu level select
the No. 8 diode and push the ON/OFF button to enter the edit mode.
By pressing the UP button, select the function to restore factory default
settings – No. 1 LED lights up.
Confirm the selection by pressing the ON/OFF – it will cause the regulator
to exit the service mode (all LED line LEDs light twice and the regulator
turns off). All editable parameters are reset to their default values.
8. ELECTRICAL CONNECTIONS AND DIMENSIONS
WARNING! Pay special attention to the connection of the regulators power
cord (L , PE, N). Connecting inconsistent to the description (e.g. replacing
"L" with "N") can lead to the appearance of the voltage at the motor
terminals, despite the fact that the regulator main switch is set to an off
position!
