Section 1 - Forward

This document provides technical information on wiring the Bristol Babcock line ofTeleFlow series products to an Invensys Auto-Adjust Turbo-Meter.

TeleFlow series (3530) units listed in Table 1-1 can be interconnected to an Invensys Auto-Adjust Turbo-Meter. Interface requirements dictate the 3530 be equipped with at least twoPulse (Counter) Inputs. The TeleFlow Plus (Model 3530-20B) is equipped with a TeleFlowCPU Board and will require the use of a BBI Low Power I/O Expansion Board since theCPU Board has only one Pulse Input. Units equipped with the TeleRTU CPU Board dontrequire an additional Low Power I/O Expansion Board (unless an additional Pulse Input isdictated) since the TeleRTU CPU Board is equipped with two Pulse Inputs.

Section 3 - Wiring

Recommended wiring is shown for connection of a Bristol Babcock Series 3530-XXX unit toan AAT. Figures 2 through 5 are provided for 3530s equipped with a TeleFlow CPU Board,i.e., 3530-10B, -20B and 50B. These units require the use of a Low Power I/O ExpansionBoard. The Low Power I/O Expansion Board provides a second counter input for the SensorRotor. Figures 6 through 9 are provided for 3530s that utilize the TeleRTU CPU Board, i.e.,3530-15B, -25B, -35B and -45B. Figure 1 shows and edge view of the BBI 3530-XXX circuitboards utilized to interface to an AAT.

Figure 1 - BBI CPUs and Low Power I/O Expansion Boards



A control amplifier/barrier is required between the AAT and the 3530-XXX; the amplifiermodel numbers shown (K numbers) in Figures 2 through 9 are for Pepprl+Fuchs devices.

Wiring diagrams are provided for the following 4 different types of amplifiers:

24 Vdc with Slot Sensor (SS)24 Vdc with Blade Tip Sensor (BTS)120 Vac with SS120 Vac with BTS

The Blade tip configuration requires +12 VDC to the AAT sensors through a MTL715+isolator made by MTL Instruments Inc.

The amplifier outputs are connected in emitter-follower mode i.e., the emitter of theoutput transistor connects to the 3530-XXX counter input which has a 1000 ohm pulldown resistor to circuit common.

+12 Vdc for the amplifier output stage is supplied from the 3530-XXX CPU Board via anExcitation (EXC) terminal. On the TeleRTU CPU Board, EXC is available from Pin #2 ofconnectors P10, P11, P12 or P13. On the TeleFlow CPU Board, EXC is available from Pin#7 of connector P14.

Section 4 - Software Configuration

In order to access data from the Invensys Auto-Adjust Turbo-Meter, you will need toconfigure the AAT Module in your ACCOL Load. Full details on configuring the AATModule are included in the AAT section of the ACCOL II Reference Manual (documentD4044).
