Configuration

6. Before supplying power to the IFT, ver-

ify that the jumpers have been properly

set in the IFT, Figure 2-5, Figure 2-8,

and Figure 2-10.

7. Terminal strip J5 on the power supply

board is used for supplying the IFT with

power. Terminal strip J6 on the power

supply board is used to supply the

probe heater with power if an HPS is

not used (Figure 2-6).

8. Ensure that the IFT 3000 is properly

earthed by way of both the internal and

external earthing hardware.

9. Ensure that the installation does not

obscure the message on either the IFT

nameplate or the IFT lid.

c. Analog Output and Relay Output

Connections

1. The microprocessor board has a

switch to select voltage or current op-

erations. Figure 2-8 shows the switch

location. In voltage mode, output is 0-

10 V. In the current mode, the output

can be configured from the setup menu

to be 0-20 mA or 4-20 mA.

2. The analog output and relay outputs

are programmed by the user as

needed. The analog output is typically

sent to recording equipment such as

chart recorders. Relay outputs are typi-

cally sent to annunciators.

3. Relays K1 and K2 are user configur-

able from the PROBE SETUP sub-

menu (Table 3-5). Typically these are

used to indicate O

values above or

below specified tolerances. OK relay is

energized when unit is functioning

properly.

4. All wiring must conform to local and

national codes.

5. Connect the analog output and relay

outputs as shown in Figure 2-11.
