Installation

Power Requirements

The 7551 requires 0.215A @ 5Vdc. Add this

to the current requirements of your system

when sizing the system power supply. Note

that this requirement excludes the use of some

modules with the 7551 in fixed SLC 500

systems.

Velocity Response Setup

A jumper on the 7551 determines how often

the module updates the velocity data. With the

jumper installed velocity data updates every

120 mSec. Removing the jumper sets the

velocity update to 32 mSec. The figure below

shows the placement of the jumper on the

7551 module.

Rack Installation

You can install the 7551 in any free slot as

long as power requirements are met. Align the

modules' circuit board with the top and bottom

card guides in the rack and gently slide the

module into the rack until the top and bottom

latches secure the module in place.

To remove the module, depress the top and

bottom latches and slide the module out of the

rack.

Compatible Transducers

The 7551 is designed for use with AMCI's

LHT Series transducers and has been tested

with Temposonics II and Balluff LDTs.

Temposonics II LDTs must have an RPM or

DPM Personality Module and Balluff LDTs

must have the 'K2' output / power supply option.

Temposonics DPM Setup

The DPM Personality Module has switches

that set the number of recirculations and the

interrogation type. When using a DPM Mod-

ule, set Switch SW1 to '4' (4 Recirculations)

and SW2 to '8' (External Interrogation).

Transducer Mounting

Refer to the documentation you recieved with

your LDT to properly mount the transducer.

LDT Power Supply

The 7551 requires a ±15 Vdc power supply for

LDT operation. MTS offers a ±15 Vdc @

0.8A supply for use with their transducers.

MTS Part Number is 380017.

UNDER NO CIRCUMSTANCES is the

-15 Vdc supply, commonly marked '-15 V', to

be connected to Power Supply or Earth Grounds.

Doing so can damage the power supply, the LDT,

and the 7551 module.
