Page 2: Brief Description
1. Brief description The RT-2 converts the position angle of a shaft into a load-independent direct current signal, proportional to the angle position. 2. Technical data Measuring input 0..90° or 0..140° (span adjustment –30/+5% of full scale) Measuring output Output variable I Load-independent DC current, proportional to the input angle. - Page 3 Installation instructions, RT-2 Power supply H DC voltage: 12...33V (Polarity reversal protection. The voltage must not fall below 12V.) Max. residual ripple: 10% p.p. Max. current consumption: Approx. 5mA + I Mechanical withstand Permissible vibration: 0...200Hz, 10 g continuous, 15 g for 2 h 200...500Hz,...

Page 5: Electrical Connections
Note that, ..the data required to carry out the prescribed measurement must correspond to those marked on the nameplate (Fig. 2) of RT-2 (measuring input, measuring output, power supply)! ... the total voltage drop do not exceed the supply voltage H[V], see “Measuring output”... - Page 6 (4.1) and (4.2) according to the wiring diagram (Fig. 3). Then fit the gland seal, pinch ring and nut. Tighten the gland nut and replace the cover. Tel.: (+45) 9614 9614 • Fax: (+45) 9614 9615 • E-mail: deif@deif.com Page 6 of 11...
- Page 7 First, switch on the power supply to the transmitter. Remove the 3 screws (3.2) and the cover (3.1) (Fig 3). Place the measured devide at its zero position, i.e. the position at which the RT-2 should produce 0 mA (three or four-wire connection), respectively 4 mA (two-wire connection) at its output.
- Page 8 If, however, a transmitter be changed from one to the other (see wiring diagrams in Fig. 4), the beginning and end of the measuring range must be readjusted. Tel.: (+45) 9614 9614 • Fax: (+45) 9614 9615 • E-mail: deif@deif.com Page 8 of 11...
