1. Power Supply Card 1.1 Switching ON the FRTU Module To switch ON the device, proceed as follows:

1. Initially, the switch is in OFF state, i.e. at Position 1 as shown in Figure 1.1.

2. Pull this switch Outward as indicated by an arrow.

3. Then move the switch downward, i.e. at Position 2 as shown in Figure 1.1.

4. Push this switch Inward as indicated by an arrow and release the switch.

5. Now the power to the device is switched ON.

Slide out the Analog Card from the rack through guides.

Identify the jumpers on the card as shown in the Figure 2.2.

To select current input or voltage input for Channels in Card, the

jumper settings need to be done. For Channels 1 to 8, jumpers J14

to J21 must be set respectively.

For current input on Channel 01: short 1st and 2nd terminal of J14.

For voltage input on Channel 01: short 2nd and 3rd terminal of J14.

Identify the DIP switch on the AI card as shown in the Figure 2.3.

Set the DIP switch address in the binary form.

Ex: Address 8 to be set.

This address is represented in binary form as 1000. Set the DIP

switches as shown in Figure 2.3.

3. Digital Input Card Each Digital Input Card accepts 16 digital inputs (2 groups of 8 each, i.e. DI1 to DI8 and DI9 to DI16) from the field. These

are classified as Single Point Information and Double Point Information.

Note: Each group of digital inputs has an individual negative terminal.

Note: The wiring connections to terminals AUX V1+, AUX V1-, AUX V2+ and AUX V2- are optional and can be used for

per-channel diagnostics and monitoring purposes only.

3.3 Wiring of Single Point Information The Single Point Information receives single information from the field data. Make the wiring connections as shown in

Figure 3.4.

Figure 3.2 Wiring of Single Point Information 3.4 Pairing of digital inputs for Double Point Information The Double Point Information receives pair information

from the field data (like breaker ON/OFF status). To wire

a pair of digital input, two consecutive channels are

wired (Refer to the Table 3.1 below). Hence 8 double

point status are obtained per card.

Note: For double point information, always wire the

digital inputs as shown in Table 3.1. Failures to

wire them in this manner will give irrelevant

information on the status of field.

Table 4.1 Pairing of digital outputs for Double commands

For Single Command, any one channel from DO1 to

DO8 can be used.

For Double Command (e.g. Circuit Breaker’s), two

consecutive Digital Output channels must be wired. The

Table 4.1 shows the two consecutive Digital Outputs that

should be wired for double command.

Note: For double command, always wire the digital outputs as shown in Table 4.1. Failures to wire them in this manner

will irrelevant information on the status of outputs.
