All Rights of the parts of the controller:INFORMATION FOR USERS ON THE CORRECT HANDLING OF WASTE ELECTRI-CAL AND ELECTRONIC EQUIPMENT (WEEE)In reference to European Union directive 2002/96/EC issued on 27 January 2003 and the related national legislation, please note that:1.

2 WEEE cannot be disposed of as municipal waste and such waste must be collected and disposed of sepa-rately;2. The public or private waste collection systems defined by local legislation must be used. In addition, the equip-ment can be returned to the distributor at the end of its working life when buying new equipment;3. The equipment may contain hazardous substances: the improper use or incorrect disposal of such may have negative effects on human health and on the environment;4. The symbol (crossed-out wheeled bin) shown on the product or on the packaging and on the instruction sheet indicates that the equipment has been intro-duced onto the market after 13 August 2005 and that it must be disposed of separately;5. In the event of illegal disposal of electrical and elec-tronic waste, the penalties are specified by local waste disposal Reading instructionsThe following symbols are used to draw the reader s attention to different warning !! General of electrical current or User manualBefore installation the user should be thoroughly familiarized with this user manual , especially with purposes, installation and care should be taken when installing and connect-ing external equipment (PTC sensor, high voltage etc) and handling the Modules correctly according to Protection against of the SE-B1/SE-B2/SE-B3/SE-B4 must be performed by authorized personnel only.

3 All warranties are excluded in case installation is performed by unauthorized personnel or in case the SE-B1/SE-B2/SE-B3/SE-B4 has not been correctly SafetyThe SE-B1/SE-B2/SE-B3/SE-B4 is a Protection device and not a safety component according to the Machinery Directive and can not be used in medical or life support plant commissioning the service technician shall ensure that personal safety requirements are met in conformity with the Machinery Directive on the basis of safety plant failures are to be immediately solved, even though no immediate danger exists; the SE-B1/SE-B2/SE-B3/SE-B4 and motor must be without manual SE-B1, SE-B2, SE-B3, SE-B4 Page 52. GeneralThe Protection devices SE-B1, SE-B2, SE-B3 and SE-B4. Hereafter SE-Bxare used for Protection of the motor against overheating by monitoring motor temperature by means of PTC-sensors mounted in the motors , other temperatures can be monitored by for example mounting PTC-sensors in the discharge outlet of a Compressor , for monitoring the oil temperature or the temperature in other areas where PTC-sensors are installed, they can also be monitored by a SE-Bx Protection module.

4 Due to their fast reaction time, good accuracy and built-in relay they can be a good solution instead of a separate control-ler. They can also be used as switch SE-Bx is default wired up for lockout in case of an overheat situation, but can also be used as a thermostat/switch relay via the cool down period of the media sur-rounding the DefinitionsProduct rangeDefinitionsHWHardware/electronicsNC Normally Closed (relay)NONormally Open (relay)PTCP ositive Temperature Coefficient (sensor element)SE-BxA SE-B1, SE-B2, SE-B3 or SE-B4 Compressor Protection modulePage 64. How toUse the SE-Bx in lockout mode SE-B1/SE-B2/SE-B3SE-B4 The wire jumper is default mounted in the two unnamed terminals located between terminals N and 12. In this mode a fault condition will need a manual reset to release the the SE-Bx in restart / hysteresis modeSE-B1/SE-B2/SE-B3SE-B4 The wire jumper between the two unnamed terminals is an overheat condition, the relay is energized again as soon as the resistance is below the lower threshold level of kOhm.

5 There is no timer function in the manual SE-B1, SE-B2, SE-B3, SE-B4 Page 75. FuntionsThe SE-Bx is a motor Protection module. By monitoring the resistance in a PTC sensor, it will open its relay when the resistance of the PTC sensor increases above the limit as shown PTC-sensor could for example be according to DIN 44081/82. The resistance of these PTC-sensors are not linear, but gives a steep rise in resistance when the thresh-old temperature of the PTC-sensor is reached. This is detected by the protective device and the relay is released and thereby cutting the control power as shown on the diagram below.

6 A manual reset must be done by removing power from the module for minimum 5 seconds and then applying it the restart blocking wire jumper is removed, the relay behaves like on the following diagram.

When the resistance in the PTC-sensors increases above 4,5 kOhm, the relay is released. The relay is released as long as the resistance is above 2,7 kOhm. When the resistance comes below 2,7 kOhm, the relay is hysteresis can be used for applications where the media where the PTC-sensors are mounted has such a large temperature inertia that this hysteresis is 86.
