Installing Analog Modules

Introduction

The method and precautions relating to the installation analog modules are detailed below.

Installation

All Premium input/output analog modules are standard format and therefore occupy a single position on the TSX RKY••• racks.

They can be installed in all positions on the rack except for the first two (PS and 00) which are reserved for the power supply module of the rack (TSX PSY•••) and the processor module (TSX 57•••) respectively. They are powered by the rack back bus, and can be positioned equally on the standard rack or on an extendable rack.

Installation Precaution

The Analog modules can be handled when the rack’s power supply is ON (ie: there is no damage or disturbance of the PLC).

When detecting terminal block presence using a shunt placed in the upper part of the terminal block, the shunt must always be screwed as tightly as possible. The terminal block must always be dismantled before dismantling the module. This avoids restoring the potential for inputs on the terminal block (up to 1700 V) during a module insulation fault.

CAUTION

MODULE DAMAGE

Installation and dismantling of modules must be done with terminal block TSX BLY 01 disconnected. Similarly, the external 24 V terminal block of module TSX ASY 800 must be disconnected.

Failure to follow these instructions can result in injury or equipment damage.

Installing the Module on the Rack

Intallation of the analog input/output modules is done on the rack in the following way :

Step	Action
1	Position the two lugs at the rear of the module (the lower part of the module) in the centring holes located on the lower part of the rack.
2	Pivot the module upwards so as to pin it to the back connector of the rack.
3	Fix the module to the rack by tightening the screw located on the upper part of the module.

NOTE: If this screw is not tightened, the module will not stay in the position of the rack.

Installing the Screw Terminal Block

The TSX AEY 414 and TSX ASY 410 modules are completed with a screw terminal block referenced TSX BLY 01. Installing the screw terminal blocks in the corresponding analog modules is done in the following way:

Step	Action
1	Once the module is in place on the rack, install the terminal block by inserting the encoder of the terminal block (lower rear part) into that of the module (lower front part) as shown below.
2	Pivot the terminal block to bring it into position to pin it on the module.
3	Fix the terminal block to the module by tightening the screw located on the upper part of the terminal block on the module.

NOTE: If this screw is not tightened, the terminal block will not stay in the position of the module.

Coding the Screw Terminal Block

The first installation of a screw terminal block on a module, dedicated to this type of connectivity involves coding the terminal block. This coding is done by transferring 2 contacts from the module to the terminal block. These contacts are indexors. They are designed to stop the terminal block being installed on another module This avoids manipulation errors during replacement of a module and guarantees electric compatibility by module type.
