Page 4: Safety
Safety Product specification Safety CAUTION 1.1 Safety instructions Installation, electrical connection, commissioning, and maintenance of the device may only be carried All personnel involved in installation, commissioning, operation or maintenance of this equipment must: out by qualified, skilled personnel and only in ac- cordance with these operating instructions. - be suitably qualified and - strictly observe these operating instructions. -
Page 5: Tt Version (Option)
Installation (oil) and winding depends on the current in the winding. The secondary current of the transducer is proportional to the current in the winding. This transducer feeds a heating element inside the mechanical thermometer. That causes an increasing indication (gradient) of the measured oil temperature according to the transformer load. -

Electrical connection Electrical connection This analogue output is an optional feature to the MESSKO BeTech Oil and Winding Temperature ® WARNING Indicators. The output is linear and proportional to the indicated temperature on the instrument dial, where Electrical voltages, danger to life! 4 mA is provided at the lowest value on the dial and All connecting wiring must be free of voltage before 20 mA at the highest value, for instance 4 mA at 0 °C... -
Page 7: Analog Output 4 - 20 Ma Current Loop Signal And 0 - 5 V Dc Voltage Output
A separate shielded cable is recommended for the wir- ing to the 4 - 20 mA analogue output. This includes the Supply Voltage and the mA output signal (= terminals 61, 62 and 63). No other signals should be wired through the same cable and make sure the shield is connected to ground on one side only. -
