displayed on the LCD) and the controller remains in standby.
When the control circuit is re-established, the controller returns
in its last state (AUTO, HAND SETTING, STOPPED, etc.).
2. OC – frost protection. At these terminals, external devices can
be connected which can stop and start the motor. The normal
working condition of the contact is when it is opened. Closing
the control circuit stops the motor ("Standby OC" message is
displayed on the LCD) and the controller stays in standby. When
the control circuit is opened again, the controller returns in its
last state (AUTO, HAND SETTING, STOPPED, etc.).
The TK alarm condition has priority over the other two CC/OC
conditions. The CC and OC are on the same priority level.
USB Mode
The USB interface gives the user the possibility to easily read,
change and write all device parameters from a PC. The user can
save all parameters into a file on disk and load them afterwards.
Just connect the USB cable to PC and USB on ST2R control board
and wait for the PC to recognize new hardware. Then run the
application (3SM.exe).
Host System Requirements:
• Microsoft Windows XP SP 2/ Windows Vista
• Microsoft .NET Framework 2.0
• One USB port available
Users with WindowsXP SP2 or SP3 must download and install
this file from Microsoft site: Microsoft .NET Framework 2.0 Serv-
ice Pack 1 (x86).
Operations
After starting 3SM.exe the user can perform the following op-
erations:
• Read parameters from USB device (ST2R)
• Save parameters into USB device (ST2R)
• Export hex file (save parameters to external file in 'IntelHEX
format' on PC)
• Import hex file (load parameters from external file on PC)
• Update firmware (select program file). New firmware and
software versions can be uploaded from www.sentera-
controls.com
• Exit
• Default values, displays the defaults of the parameters
Formatting of time values may be "h", "hh", "hh:mm", "h:mm", "hh/
mm" or "h/mm". Start times must be before end times. When
a change is made in the start or end times it is automatically
transferred to the switching times field (for the corresponding
day of the week).
There are two main fields:
1. Main Settings
1.1. Language (English by default)
1.2. Time and date
1.3. User Code (disabled by default)
1.4. Installer Code (disabled by default)
2. Installation
2.1. Presets – Monday/Friday and Saturday/Sunday. When a
change is made in the start or end times, it is automatically
transferred to the Switching Times field (for the corresponding
day of the week).
2.2. Switching times – here can be set switching times for the
particular day of week.
2.3. Exceptions – there are 50 user programmable exceptions
which can set switching times different from the previously
mentioned. The date of the exception has to pass the current
date otherwise it is not allowed.
Standby intervals are all automatically calculated and are upda-
ted after each change.
In USB mode the ST2R controller is in STOPPED mode and the
functionality of the buttons and alarm conditions are disabled.
Transport and stock keeping
Avoid shocks and extreme conditions, stock In original packing.
Warranty
Two years from delivery date against defects in manufactur-
ing. Any modifications or alterations to the product relieve the
manufacturer of all responsibility.
The manufacturer bears no responsibility for any misprints or
mistakes in this data, and modifications or improvements to the
product can be made at any time after date of publication.
Maintenance
In normal conditions the controllers are maintenance-free. If
soiled clean with dry or dampish cloth. In case of heavy pol-
lution clean with a non-aggressive product. In these circum-
stances the controller should be disconnected from the mains.
Pay attention that no fluids enter the controller. Only reconnect
the controller to the mains when it is completely dry.
Motor protection
It is recommended with motors to seperately install a thermal
protection.
All works may only be carried out by skilled personnel
following the local regulations and AFTER the controller
is completely separated from the mains. Replace fuse only
with same type and rating.

Deze transformator-regelaars zijn gebaseerd op het principe
van spanningsregeling d.m.v. autotransformatoren. Zij zijn toe-
pasbaar op spanningsregelbare motoren (230 V - 50/60 Hz) voor
het regelen van toerentallen (van ventilatoren, pompen ed.).
Door de ingebouwde klok kunnen deze transformatorregelaars
volledig autonoom werken. Bij inbedrijfsstelling kunnen twee
snelheden (hoog en laag) gekozen worden uit de reeks 80-100-
120-150-170-190-230 V. De werkingstijden van de hoge en lage
snelheid kunnen in de klok geprogrammeerd worden samen
met een motorstoptijd (dag/week-programma). Dit laat een
perfecte controle toe, bv. dag/nacht.
Montage
De regelaars dienen op een vlakke wand gemonteerd te wor-
den. Sluit de netvoeding, motor(en) en aarding aan met ka-
bels van de gepaste diameter op de aansluitklemmen volgens
schema. Aan de netzijde dient een hoofdschakelaar voorzien te
worden met aanbevolen hoofdzekeringen.
