INTRODUCTION
OPAT is an electromechanical control unit for proportional directional and pressure relief valves.
It can control two separate solenoids with total power consumption of up to 800 Ma, but not
simultaneously.
OPAT is ATEX and IECEx approved according to NS-EN60079 (IECEx 60079) for use in
potentially explosive atmospheres.
The unit is primarily intended for use with Hawe PM pilot valves. Units with model codes BTN or
SDE feature a built-in solenoid, whereas units with model code XS have a separate connection
housing for an external solenoid. The power consumption of external solenoid must not exceed
800 mA
The control system communicates with Profibus or CANbus, depending on type. All types have a
series of analogue inputs for use when bus communication is not required.
The unit has been manufactured in compliance with applicable regulations and standards, see
Declaration of Conformity for details. As the unit has been type approved according to these
standards, any alteration or modification of the unit which is not specifically described in this
User Manual will void the type approval, and relieve the manufacturer/distributor of any
responsibility.
This User Manual is intended for personnel with relevant training, and it is essential that any
person installing, commissioning or adjusting the unit has in-depth knowledge of the contents
of the User Manual and the following technical data sheets:
