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.

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 (high voltage etc.)

5 And handling the modules correctly according to protection against of the OLC-D1/OLC-K1 must be performed by authorized personnel only. All valid national legislations regarding electrical installa-tions must be warranties are excluded in case installation is per-formed by unauthorized personnel or in case the OLC-D1/OLC-K1 has not been correctly SafetyThe OLC-D1/OLC-K1 is a protection device and not a safety component according to the Machinery Directive and cannot 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 OLC-K1 is for monitoring oil Level in compressors while the OLD-D1 is for Controlling levels in relay in OLC-K1 is used in the safety chain for the compressor and will open and lock-out in case of a failure. OLC-D1 is meant for keeping a specified Level in a vessel by turning the relay on and DefinitionsProduct rangeDefinitionsESDE lectro Static DischargeHWHardware/electronics OLCO ptical Level Controller NCNormally Closed (relay) NONormally Open (relay) Technical manual OLC-D1, OLC-K1 Page 54. FunctionsThe OLC series consists of the two models, OLC-D1 and OLC-K1.

7 They have different monitoring functions which are listed in the Level monitoringThe OLC series consists of a screw-in prism unit and an Optical Level detection device. The prism unit is installed in the compressors oil chamber or in the vessel. The Level detection device can be replaced without open-ing to the pressurized part of the compressor or vessel. Detection of the Level is via infrared light. There is a built-in monitoring system for correct Oil Level monitoringThe OLC-K1 is used for contactless oil Level monitoring in compressors in order to safeguard sufficient lubrication of the internal the refrigerant can be absorbed by oil, fluctuation of the oil Level in the compressor is common in refrigeration systems and thereby oil levels need to be is for compressor use and locks out if oil Level is not sufficient after 90 seconds of compressor Level monitoring in vesselsThe OLC-D1 is meant for Level monitoring in vessels and does not have the operation recognition input needed for compressor operation.

8 The OLC-D1 releases the relay if the Level is too low and activates the relay if the Level is valid. There is a 5 seconds time delay between switching the Red LED status lightAt start-up, the OLC will flash shortly with the LED. After approx. 3 seconds the relay will be activated. For OLC-D1 the Level monitoring starts immediately; for the OLC-K1 monitoring starts when the D1 signal is applied and after the 90 seconds delay time the Level is evaluated. If the oil Level is too low or there is a failure, the relay will be opened and the LED will signal the failure. LED Off: Oil Level good, no failures LED On: Oil Level low LED flashing: OLC not correctly mounted, or Supply voltage too low, or Internal failurePage 65.
