UNPACKING
Unpack the instrument carefully. Make sure all components
have been removed from the foam protection. Inspect all
components for damage. Report any concealed damage to
the carrier within 24 hours. Check the contents of the carton/crates against the packing slip and report any discrepancies to Magnetrol. Check the nameplate model number
(Model number/approvals as per inserted separate sheet) to
be sure it agrees with the packing slip and purchase order.
The Eclipse® AuroraTM model number defines:
- The Magnetic Level Indicator.
- The Eclipse® Guided Wave Radar transmitter and switches/transmitters: each of these components have their
own modelnumber that refers to their own approvals /
instruction manuals (as per separate inserted documents).
Check and record the Eclipse® AuroraTM serial number for
future reference when ordering parts.
Pre-installation checklist:
- Verify if the units’ center to center distance equals the
center to center distance of the vessel.
- Locate the external mounted switches/transmitters.
These are seperately packed (for proper mounting/installation; see included instruction manuals).
- Locate the Eclipse® amplifier head (for proper mounting/installation – see Eclipse® instruction manual).

CAUTION: When handling longer units, assure that these are supportered over the entire length to avoid bowing
causing deformation / glass breakage.
MOUNTING – Magnetic Level Indicator
Springs protect the float
during transport/operation.
Shut off valves
are recommended.
Note: The float and the guided wave radar probe are pre-mounted into the magnetic level indicator. The float is protected
against transport damage and operational conditions by means of internal springs.
CAUTION: In case shut off valves are used, care must be taken when opening the valves to prevent a surge of
fluid and gases through the chamber. A surge can cause the float to be propelled to the far end of the chamber,
and float damage could result.

MOUNTING – Magnetic Level Indicator
Reassembly guidelines
Reassembly guidelines for the float / GWR probe in case
these need to be dismantled for eg. cleaning of the cage:
- Verify that the “TOP” marking on the float is pointing
upwards when re-installing.
- Make sure that the float is positioned in between the
cage wall and the baffle plate, when re-installing.
- Verify that the GWR probe is installed the farthest away
from the flapper rail.
- Assure proper sealing of the gaskets.

CAUTION: Do not reposition the indicator rail from

TROUBLESHOOTING
Problem
Solution
Flags do not rotate with level change.
Test flags with a magnet from bottom to top (magnet not included). If
flags test O.K, check for float obstruction (see maintenance).
Switch does not actuate with level
change.
Check micro switch for continuity. Replace if damaged, if O.K, remove
switch from piping column and test switch magnet assembly with realignment magnet, by moving magnet over the housing face. If the
switch magnet assembly fails to respond, replace the switch. If the
switch checks O.K, check float travel.
Reed transmitter does not track level.
Remove transmitter assembly from piping column and test with realignment magnet. Run magnet from bottom to top of reed chain.
Check zero and span calibration. If no change in output, replace.
Flags rotate at different height than actual
level.
Float selected for different specific gravity. Replace float with a float
with correct specific gravity rating. Confirm correctness of float orientation. Top is up.
Float inside the level gauge is moving
slow or not at all.
Make sure the MLI is level vertically.
The process fluid being measured may be too viscous and heat tracing
may be required to make the material more fluid. Heat tracing can be
purchased from the factory.
The specific gravity of the process fluid and the float weight may need
to be reverified.
The liquid being measured may contain magnetic particles collecting on
the magnetic section of the float causing drag. If this happens, magnetic trap assemblies can be purchased from the factory.
Visual inspection of the float may be required to see if the float has collapsed.
Scale is at zero to the center of the bottom proces connection, but the indicator
is above or below zero.
The scale assembly is mounted to the chamber using stainless steel
gear clamps. It can be easily adjusted in the field using a screwdriver.
make sure the scale zero is in line with the center of the process connection.
The float stop spring at each end of the chamber is there to cushion as
well as position the float assembly to the center of the process connection. Make sure top or bottom float stop springs are not bent or broken.
Indicator has uncoupled and fallen to the
bottom of the glass tube.
In some “flashing” applications, the float may rise or fall quickly.
Consult factory for suggestions to help avoid this.
To re-couple the indicator to the float, simply use a small magnet and
run it along the length of the chamber to locate the float. Mark the location of the float on the outside chamber. Use the small magnet to couple with the indicator and pull the indicator up to meet and couple with
the float.
Make sure all stainless steel gear clamps are tight. The scale channel
must be tight against the chamber.
* Assure unit installation is level.
MAINTENANCE
If the process liquid is clean (no solids or deposits), the MLI should require minimum maintenance. If the process liquid is dirty
(solids and deposits), it is recommended the external cage be isolated from the process and flushed periodically. For complete
cleaning, after draining the unit, remove the bottom flange and float, inspect cage and float for build up and clean if required.
Magnetic traps are available to prevent magnetic particulate travel from the vessel to the chamber.

MODEL IDENTIFICATION – CROSS REFERRENCE PARTNUMBERS ECLIPSE AURORA
The Eclipse Aurora partnumber defines the Eclipse transmitter and the GWR probe partnumbers into one model code. The
original model code of the Eclipse electronics should be used for approval and spare part referrence of the electronics. This
number is available on the nameplate of the Eclipse transmitter (see page 2) or you can use the below cross refererence partnumber to rebuild the equivalent Eclipse partnumber from the Eclipse Aurora partnumber.

SERVICE POLICY
Owners of Magnetrol products may request the return of a control; or, any part of a control for complete rebuilding or
replacement. They will be rebuilt or replaced promptly. Magnetrol International will repair or replace the control, at no cost to
the purchaser, (or owner) other than transportation cost if:
a. Returned within the warranty period; and,
b. The factory inspection finds the cause of the malfunction to be defective material or workmanship.
If the trouble is the result of conditions beyond our control; or, is NOT covered by the warranty, there will be charges for labour
and the parts required to rebuild or replace the equipment.
In some cases, it may be expedient to ship replacement parts; or, in extreme cases a complete new control, to replace the
original equipment before it is returned. If this is desired, notify the factory of both the model and serial numbers of the
control to be replaced. In such cases, credit for the materials returned, will be determined on the basis of the applicability of
our warranty.
No claims for misapplication, labour, direct or consequential damage will be allowed.
RETURNED MATERIAL PROCEDURE
So that we may efficiently process any materials that are returned, it is essential that a “Return Material Authorisation” (RMA)
form will be obtained from the factory. It is mandatory that this form will be attached to each material returned. This form is
available through Magnetrol’s local representative or by contacting the factory. Please supply the following information:
1.

Process details
All shipments returned to the factory must be by prepaid transportation. Magnetrol will not accept collect shipments.
All replacements will be shipped FOB factory.
