Installing and Operating Instructions
1 Introduction
1.1. General Warnings
Please read the following safety precautions and warnings before using this manual:
CAUTION!
• This manual is part of the product and should be kept near the device for easy and quick reference.
• The device should not be used for purposes different from those described in this manual. It cannot be used as a safety device.
• Check the application limits before proceeding.
• Emerson reserves the right to change the composition of its products, even without notice, ensuring the same and unchanged functionality.
SAFETY PRECAUTIONS!
• Check that the supply voltage is correct before connecting the device.
• Do not expose to water or moisture: use the controller only within the operating limits and avoid sudden temperature changes with high
atmospheric humidity to prevent condensation from forming.
• Warning: Disconnect all electrical connections before performing any kind of maintenance.
• Fit the probe where it is not accessible by the end user. The device must not be opened.
• In case of failure or faulty operation, send the device back to the distributor or to Emerson (see address) with a detailed
description of the fault.
• Verify the maximum current that can be applied to each relay (see section 16, Technical Data).
• Ensure that the wires for probes, loads, and the power supply are separated and far enough from each other without crossing or intertwining.
• In case of applications in industrial environments, the use of main filters in parallel with inductive loads could be useful.
