3 Maintenance

The Enhanced Analog Module and its associated I/O assemblies require minimal maintenance. Some
routine maintenance is recommended in the form of a visual inspection and a possible cleaning.

DANGER

Electrical shock hazard

Explosion hazard

Will cause death, serious injury or property damage

•

Remove power from all wires and terminals and verify that there
are no hazardous voltages before working on equipment.

•

In potentially hazardous atmosphere, remove power from
equipment before connecting or disconnecting power, signal, or
other circuit, or extracting/inserting module.

•

Observe all pertinent regulations regarding installation in
hazardous area.

•

Ensure all devices are rated for hazardous (classified) locations.

3.1

Tool and Equipment Requirements

The following tools and equipment are necessary for servicing:

•

Common electronic servicing hand tools

•

Digital Multimeter (DMM): Accuracy, ammeter s/-0.05% of reading

3.2 Visual

Inspection

The EAM and its associated assemblies should be subjected to a periodic visual inspection. The
frequency of inspection will depend on the severity of the operating environment.

The primary aim of the inspection is to reveal any excessive accumulation of dust, dirt, or other foreign
material adhering to the surfaces of transition board and protective covers of an EAM. Accumulation of
dirt and dust prevents efficient heat dissipation and may cause module or system failure. An EAM
installed in a cabinet complying with the NEMA 12/IP55 specification need not be inspected for
cleanliness. Refer to section 3.3 for cleaning instructions.

The status of the EAM is indicated by an LED located on its bezel. Refer to section 3.4 for LED
indications.
