Page 4: Introduction
BCM-W 1 Introduction 1.1 Intended Use Oil moisture sensors are used to monitor the water content in oils and the temperature. Oil moisture sensors must not be used in highly flammable or corrosive liquids. Please note the technical data in the appendix for the specific intended use, existing material combinations, as well as temper- ature limits. -
Page 5: Design Types
BCM-W 1.3 Design types The BCM is available as three basic models: Model Description BCM-WS Sensor without display BCM-WD Sensor with display (display built into the sensor) BCM-WR Combination of sensor and display (display for external installation) The BCM will have different switching and analogue outputs depending on the configuration. The outputs are freely program- mable. -

BCM-W 4 Setup and connection DANGER Electric voltage Risk of electric shock a) De-energise the system. b) The equipment may only be installed, maintained and put into operation by instruc- ted, competent personnel. c) Always observe the applicable safety regulations for the operating site. -
Page 10: Installation Recommendation
BCM-W 4.1.1 Installation recommendation Proper moisture sensor function requires the entire sensor element to be inside the medium at all times. The sensor version is suitable for installation at the side of the tank. Here the installation position should be below the minimum liquid level. When installing into a return pipe, be sure not to exceed the maximum flow rate. -
Page 11: Operation And Control
BCM-W 5 Operation and Control NOTICE The device must not be operated beyond its specifications. 5.1 BCM-WD/BCM-WR This explanation of operation refers to the versions with display unit. 5.1.1 Start-up procedure The device will automatically switch on when connected to power. It will first briefly display the software version, at which time the device will also check the built-in components. -
