Maintenance and troubleshooting

The CoreSense™ M10 monitoring system does not require regular maintenance and does not contain
any field-serviceable parts. Fuses may need replacement if they have been submitted to an unusual
voltage event.
• In accordance with IEC61010-1 edition 3.0, to prevent contamination of the electronics by outside
elements, the analytical unit cabinet cover shall be opened only under controlled environmental
conditions defined as:
– Temperature: between 5 °C (41 °F) and 40 °C (104 °F)
– Maximum relative humidity: 80% for temperatures up to 31 °C (87 °F), decreasing linearly to 50%
relative humidity at 40 °C (104 °F).
• Do not expose the cabinet innards to unstable weather events (rain, snow, hail, etc.)
• Use only fuse(s) specified as appropriate for this equipment (see "Technical specifications" on
page 83).

Closing the analytical unit door

The CoreSense M10 analytical unit complies with the IP66 and NEMA 4X standards.
Before you close the door, it is important to verify that the screws holding the cable cover on the right-
hand side, and the screws holding the terminal block cover are tightened so as not to cause vibrations
when the unit is operational.
To ensure that the unit remains standards-compliant when you close the unit door, you must tighten
the unit latch screws to 9 N·m (80 lbf.in) by following the sequence indicated on page 61.

Cleaning the system

In accordance with your company's procedure:
• Perform a visual inspection of the sensor head and analytical unit, checking for oil leaks, and water,
snow or sand accumulations. Wipe off any such accumulation with a clean cloth.
• Make sure that all enclosures and the connecting cable are properly secured.

Troubleshooting

Most problems that could happen within the CoreSense M10 monitoring system will be recorded as
events in the Events log. You will be informed of these problems either with alarms or by looking at the
LEDs on the system cabinet or sensor head. The meaning of the various LEDS is explained below.
