OPERATION
6.1.
Operating mode selection
On the speed controller’s board there is a SW1 switch by which you can
choose the control type - with the keypad (D mode) or 0-10V signal (mode
A). Switching must be done in OFF state in accordance with the Fig. 4.
6.2.
Keypad based control (D mode)
The DSS2 T-BIS_P regulator keypad (Fig. 3) is placed on the facade.
It allows using all the features of the device without the need for external
controllers and to monitor the current state of work.
Fig. 3. DSS2 T-BIS 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 press the
ON/OFF
button. The regulator starts
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 regulator. The fan slows
down smoothly, which is signalized by blinking of a LED indicator bar.
If the power is disconnected during work and then is connected again, the
regulator will start working with the last memorized fan speed.
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 +16 VDC voltage supply,
which can be used to power the DEN10 or DEN11 controller.
In
DSS2 T-BIS_P
signalling of work, alarm and speed level is done through
LEDs in the same 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 T-BIS
there are no buttons or indicator LEDs.
6.4.
TK alarm indication
The red LED indicates
ALARM
of motor overheating. It is detected by
thermocontact switch opening. The regulator turns the engine off. After
the engine has cooled, the alarm LED flashes for 10 seconds and the
engine switches on again.
The alarm is displayed only on the regulator’s keypad. A regulator without
a keypad does not have a LED alarm signaling.
7.
SERVICE MODE
The 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 and K1 contactor operation mode.
7.1.
Entering and navigation in the service mode
To enter the service mode the regulator must be in operation mode (the
LED "
RUN
" is lit). Simultaneously press and hold
UP
and
DOWN
buttons
for 6 seconds. The moment of entering the service mode is indicated by
the LED line blinking.
After entering the service mode, the
1
st
menu level
is selected –
parameter selection mode.
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. 6). After making your
selection by pressing the
ON/OFF
button, the regulator goes into the
2
nd
menu level
– parameter edit mode. This state is indicated by 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% or the currently selected option.
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
1
st
menu level
.
After editing in order to save the set values and to leave the service mode,
press simultaneously
DOWN
and
UP
buttons in the
1
st
menu level
. The
LED line will blink 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 exiting the service mode using keys
DOWN
and
UP
in the
manner described above.
7.2.
