After unpacking, inspect all components to see that no
damage has occurred during shipment. For top mounted
units, care should be taken not to bend the displacer stem
or enclosing tube during unpacking or installation.
Caution:
If re-shipping to another location, displacer must again
be secured using same strap and wire assembly.

REMOTE UNITS
The wiring of the EZ Modulevel transmitter assembly, to the
LVDT assembly, is pre-wired from factory by 6 conductor
cables. When transmitter housing is remote mounted by
means of a cable, use the following cables:
The 6 discrete conductors are tagged 1 through 6, and
should be secured to their respective terminals on both
terminal blocks.

CALIBRATION – LEVEL
OPERATING MODE
EZ Series transmitters are factory set in the direct acting mode (a rising level increases output signal 4-20 mA). If reverse
acting mode is required remove transmitter housing cover carefully and position direct-reverse switch on printed circuit board
to 'reverse'.
CALIBRATION USING PUSHBUTTONS
TESTING on BENCH CALIBRATOR
NOTE: Default Error signal setting
from factory = 22 mA.
The EZ Modulevel bench calibrator is designed to test the
electronics of the unit. The bench calibrator can also be
used for calibration purpose but the calibration requires fine
tuning versus actual levels in the field.
Slide the electronic head over the open topped enclosing
tube, making sure that the white plastic washer is in
place.
Direct action 4 to 20 mA at rising level:
1. Calibrate 4 mA/0 % level
Rotate «ZERO» control untill the local meter (use a
multimeter for blind transmitters) reads 4 mA or 0 %.
2. Calibrate 20 mA/100 % level:
Rotate «SPAN»control untill the local meter (use a
multimeter for blind transmitters) reads 20 mA or 100 %.
3. In case 100 % level cannot be established:
Establish liquid level at highest possible level.
Rotate the «SPAN» control untill loop signal
corresponds with % of actual level.
eg. 80 % level should match:
(20 mA – 4 mA) x 80 % + 4 mA = 16.8 mA.

1. Calibrate 4 mA/0 % level:
Slide the adjustment rod completely down into the
enclosing tube.
Rotate «ZERO» control untill the local meter (use a
multimeter for blind transmitters) reads 4 mA or 0 %.
2. Calibrate 20 mA/100 % level:
Align the scale of the adjustment rod with the SG of
your medium.
Rotate «SPAN»control untill the local meter (use a
multimeter for blind transmitters) reads 20 mA or 100 %.

IMPORTANT
BENCH CALIBRATION DOES NOT COMPENSATE FOR ELAVATED TEMPERATURES
Specific gravity needs to be set in function of selected unit (see partnumber) to establish 100 % level output:
E8x-J/M/A/D/Qxxx-Exx =
align adjustment rod with real specific gravity
align adjustment rod with real specific gravity
E8x-K/B/N/E/Rxxx-Exx =

align adjustment rod with real specific gravity

IMPORTANT
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
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.
