Page 3: Product Features
PRODUCT FEATURES OPTISENS OAM 1050 1.1 Turbidity measuring system with innovative cuvette technology The compact turbidity measuring system OPTISENS OAM 1050 OPTISENS OAM 1050 uses the 90° scattered light OPTISENS OAM 1050 OPTISENS OAM 1050 method to scan liquid samples in glass cuvettes. This means that the measurement optics are not directly exposed to the sample and thus require less maintenance. -

Before fixing a cable, look an the labels on the board and especially regard polarities! • To establish the electrical connections in the correct way, follow the order of the following sections and their instructions. 07/2011 - TD OPTISENS OAM 1050 R02 en www.krohne.com... -
Page 18: Connecting The Cables In The Field Terminal Box
• Fix the cable on the terminal like in the following drawing (1 to 5). • Use the strain relief strap to reduce the tension on the power terminals (6). • Close the terminal box and assure that it is properly sealed. www.krohne.com 07/2011 - TD OPTISENS OAM 1050 R02 en... -
Page 19: Alarms Terminal (Signal Output)
• Do not run 4...20 mA or RS 485 cables in the same conduit as power as this could lead to signal interferences. • When using the RS 485 interface, equip the last device on each bus with a 120 Ω terminating resistor to eliminate signal reflection on the line. 07/2011 - TD OPTISENS OAM 1050 R02 en www.krohne.com... -
Page 20: Connecting The Sensor Interconnect Cable
Always connect the sensor interconnect cable with the upper part of the device last of all! The reason is that if you connect the sensor interconnect cable before the internal wiring, energising the device with power could destroy or damage the device! www.krohne.com 07/2011 - TD OPTISENS OAM 1050 R02 en... -
