Page 7: Installation
Installation Installation The signals should be wired as shown in Table 1: Table 1 – Signal wiring between RLE or HS20 and RLI20 2.1 Analogue quadrature interface Signal Function 1st pair Sine and /Sine The RLI20 accepts the nominal 1 Vpp analogue quadrature 2nd pair Cosine and /Cosine from the RLE or HS20. - Page 8 Installation Input connector pinout The analogue quadrature input connector pinout is shown in Table 2. All pins are protected to ±7 V. The connector on the RLI20 is a 15 way female D-type. Figure 1 shows the mating D-type connector. Table 2 –...

Installation 9 way D-type Serial interface The RLI20 outputs RS485 serial data at 2.5 Mbps. Cabling A screened twisted pair is recommended with SD+/SD- as one pair 0 V/5 V as second pair and outerscreen as chassis. The connection on the RLI20 is a 9 way male D-type, the mating Figure 2 –... -
Page 10: Error Output
Installation Error output Power The RLI20 outputs on RS422 compatible error signal. The RLI20 power is supplied via a 4 way male M16 Binder, the mating connector is shown in Figure 4. Pinouts are shown Cabling in Table 5. This is identical to wiring requirements for RCU10 power connector. -
Page 11: Mechanical Installation
Installation Mechanical installation For connector/cable clearance purposes, allow 100 mm (4 in) from the front face of the RLI20. The RLI20 is intended to be mounted in an electrical control cabinet or similar environment. It is constructed with IP40 Note: Using the fixings supplied with the unit (M4 x 5 cap protection and therefore needs to be protected from harsh head screws and 4 mm plain washers) ensures that earthing is environmental conditions. -
Page 12: Configuration
Configuration 3 Configuration Note: The RLE will flag an error when the measurement velocity reaches a level at which the required output rate of the 3.1 RLE set-up – dip switches digital quadrature exceeds the digital bandwidth limit of the RLE. The digital bandwidth limit depends on the digital quadrature If the RLI20 is being used with an RLE system, care should be resolution and maximum output bandwidth selected with the... -
