Step 16. Verify that the hardware has been installed correctly.

For AutoMate systems, you must configure the AutoMate

processor using the AutoMate Programming Executive

(APX) before testing. See section 4.0 for more

information. After configuring the module, use the APX

Point Monitor function to test the module. You can test the

Analog Rail module input channels by verifying that the

input signal in the channel (4Ć20mA) is proportional to an

ammeter reading at the terminal points.
For DCS 5000, AutoMax, or Distributed Power DĆC Drive

systems, use the DCS 5000 or AutoMax Programming

Executive software I/O Monitor function, respectively. To

test the input channels, verify that the input signal in the

channel (4Ć20mA) is proportional to a ammeter reading at

the terminal points.

Module Replacement

Use the following procedure to replace the module.
Step 1.

Stop any application programs that are running.

Step 2.

Turn off power to the external hardware connected to the

input channels on the faceplate of the module.

Step 3.

Turn off power to the Analog Rail module (120 VAC or

24 VDC).

Step 4.

Turn off power to the Reliance device connected to the

Analog Rail module.

Step 5.

Disconnect the I/O Rail cable from the Analog Rail

module.

Step 6.

Without disconnecting the wiring, remove the 12Ćpoint

terminal from the faceplate and set aside.

Step 7.

Without disconnecting the wiring, remove the 4Ćpoint

terminal from the faceplate and set aside. Disconnect the

ground wire from the bottom of the rightĆhand flange.

Step 8.

Loosen the screws that hold the Analog Rail module to

the panel and remove the module.

Step 9.

If the power supply you are using is 24 VDC, you need to

replace the factoryĆinstalled .25A fuse in the new module

with the .75A fuse that came in the shipping box with the

module. Use a screwdriver to release the fuse holder

located on the Analog Rail module faceplate. Pull the fuse

holder out of the module.
Remove the .25A fuse from the fuse holder and replace it

with the .75A fuse. ReĆinsert the fuse holder into the

module. Turn the screwdriver clockwise while pressing

down on the fuse holder at the same time. The fuse

holder must be flush against the faceplate.

Step 10. Remove the two plug connectors from the faceplate of

the new module by pulling them firmly away from the

faceplate.

Step 11. Place the new module over the pattern drilled and attach

it securely to the panel with #10 or M5 studs or bolts.
