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 car-
ton/crates against the packing slip and report any discrep-
ancies to Magnetrol. Check the nameplate model number
(Model number/approvals as per inserted separate sheet) to
besure it agrees with the packing slip and purchase order.
The Vizual®model number defines:
- The Magnetic Level Indicator.
- The Vizual®transmitter and/or switches: each of these
components have their own modelnumber that refers to
their own approvals (as per separate inserted docu-
ments).
Check and record the Vizual®serial number for future refer-
ence 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.
- Locate the float – separately packed.

CAUTION: When handling units with longer measuring range, assure that these are supported over the entire
length to avoid bowing causing deformation / glass breakage.
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,
resulting in float damage.

conditions. It might occur that the float indication is
incorrect at the time of start up under ambient con-
ditions.

Switches/transmitter and scale can easily screwed on the
indicator rail. Simply,slide the fastening screws down on the
rail to the desired location and fasten with the locking
screws.
Both sides can be
used to either mount

WIRING – Transmitter
The Vizual®reed chain transmitter is pre-calibrated from factory
following the level indication of the MLI. The 4 mA setting is
marked on the chain and should correspond to the marking on the
MLI. Please consult factory if the measuring span needs to be
reset to other values than the default factory settings.

WIRING – Switches
The switch will actuate slightly above the center of the unit
and de-actuate slightly below the center of the unit.
Make sure that the switches are always properly retightened
onthe indicator rail.
CAUTION: Power must be switched OFF before

Make sure that the switches are always mounted as close
aspossible to the indicator rail.

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 that the external cage be isolated from the process and flushed periodically. For com-
plete cleaning, after draining the unit, remove the bottom flange and float, inspect cage and float for build up and clean if
required.

TROUBLESHOOTING
Problem Solution
PHYSICAL SPECIFICATIONS
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 if float is present or for float obstruction (see
maintenance).
Switch does not actuate with level change. Check switch for continuity. Replace if damaged, if O.K, remove switch
from piping column and test switch magnet assembly with re-alignment
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 re-
alignment 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 orienta-
tion. Top is up.
Float inside the level gauge is moving slowly
or not at all.
Make sure the MLI is levelled vertically.
The process fluid being measured may be too viscous and heat tracing
may be required to make the material more fluid.
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.
Visual inspection of the float may be required to see if the float has col-
lapsed.
Scale is at zero to the center of the bottom
process 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 con-
nection.

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. Purchaser Name
2. Description of Material
3. Serial Number and Ref Number
4. Desired Action
5. Reason for Return
6. 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.
