Introduction
The OS2 230 V 6A ac Controller forms the basis of the SE Controls mains
voltage solutions.
The panel is for single zone applications and is fully CE marked. Environmental
Ventilation control panel capable of receiving thermostatic inputs and BMS
signals.
These modular building blocks can also be networked across buildings using
SE Controls OSlink technology to deliver targeted, intelligent systems.
Expandible through OSlink.

OS2 230 V AC Controller
Technical Information & Operating Instructions
Please keep these operating instructions for future reference and maintenance.
Application
The OS2 AC Controller is a 230 V ac control
unit designed for use with 4 wire 230 V ac
actuators in a natural ventilation system.
The controller can either be mounted locally
to the device to be operated or as part of a
centralised group in a plant room.
Subject to technical modifications. Diagram is not binding.

The installer must not adjust or remove original manufacturers cabling or use terminal outputs or inputs for purposes other than their design purposes without the written authorization from SE Controls.

Page 8: Mains Power Connection
Connection to the actuators is made using 3 core + earth cable of suitable cross-section to carry the maximum actuator current. In operation, the actuator power is timed off automatically after a period defined for the mode of operation. For Caretaker, Rain and Thermostat demands this period is 180 seconds (Factory adjustable). For day to day and 0-10 V demands the default period is 18 seconds (Factory adjustable). The default actuator output mode is for motor open/motor close actuators. Other devices (such as magnetic catches) can be selected at the factory by SE Controls.

3.4. Control Connections Each controller can operate either as a stand alone unit or as part of a BMS managed control system. To allow for this level of control complexity, 7+1 control inputs are provided in the basic controller. The following list identifies the 7 controls in their priority order; Caretaker Demand Slave Demand &... -
Page 10: Follow Inputs
3.8. Rain Sensor Connecting RNS to 0 V will close all attached actuators. By default, the thermostat, Day to Day and 0-10V inputs are all ignored under this condition. The lockout of the Day to Day input and 0-10 V inputs can be modified at the factory by SE Controls. By default, breaking the connection between RNS and 0 V will not alter the position of the actuators (factory adjustable). In operation, the actuator power is automatically timed off after a period of 180 seconds (factory adjustable). This is a sufficient length of time to ensure most actuators achieve their fully closed position as required. To prevent ‘machine gun’ operation of the actuators, rain sensor movements are also subject to the 180 second (factory adjustable) lockout period, during which period other rain sensor input changes are ignored. -
Page 11: Day To Day Switch
3 position switch having 2 normally open contacts is used. In operation, power is applied to the actuator only during the period when one of the contacts is closed. This mode of operation is factory adjustable by SE Controls. In the open direction, the actuator power is automatically timed off when a total period of 18 seconds (factory adjustable) is exceeded. -
Page 12: 0-10V Analogue Input
The exception to this is if the input voltage is set to 0 V. In this case, the controller will apply power in the close direction to the actuator but will time off after a period of 180 seconds (factory adjustable) to guarantee the fully closed position is reached. By default, the 0-10 V input is assumed to be an automatic control but can be adjusted at the factory by SE Controls to be a manual control. 3.12. -
