UNPACKING
U
npack 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 to
be sure it agrees with the packing slip and purchase order.
Check and record the serial number for future reference
when ordering parts.
MOUNTING
SPECIAL CONDITIONS FOR ATEX USE
These units are in compliance with:
1.The EMC directive 2014/30/EU. The units have been tested to
EN 61326: 1997 + A1 + A2.
2.Directive 2014/34/EU for equipment or protective system intended for use
in potentially explosive atmospheres. EC-type examination certificate number

1.The enclosure contains aluminum and is considered to present a potential risk of ignition by impact or friction. Care must
be taken during installation and use to prevent impact or friction.
2. To maintain the T6 and/or T4 temperature code care shall be taken to ensure the “Enclosure Temperature” does not
exceed 70 °C.
3. The risk of electrostatic discharge shall be minimized at installation, clean non-conductive surfaces with moist cloth only.
4. Contact the original manufacturer for information in the dimensions of flameproof joints.
5.For installation with ambient temperature of 70 °C, refer to the manufacturer’s instructions for guidance on proper selection
of conductors.
6. The ultrasonic probe is only for use with the Echotel ultrasonic switch.

ET UP AND FUNCTIONS
Set up
High – Low Level Failsafe selection:
¿
In «Hi» position, the current will shift to 12/16 mA (report alarm) when the transducer is wet.
In «Lo» position, the current will shift to 12/16 mA (report alarm) when the transducer is dry.
In both positions, the current will stay at 8 mA to report a safe condition.
Fault selection:
Select for which signal the unit should report a malfunction ≥ 22 mA or ≤ 3,6 mA
T
ime delay setting:
Turning the potentiometer clockwise will increase the time delay from 0,5 s to 10 s. Time delay is typically used where turbu-
lence, boiling or splashing can cause false level alarms.

Use the following settings to replace Echotel 915 series with the new Echotel 961 series:
For High Level Failsafe, use «Lo» setting = low current draw (from 16 mA (safe) to 8 mA (alarm))
For Low Level Failsafe, use «Hi» setting = high current draw (from 8 mA (safe) to 16 mA (alarm))

MAINTENANCE
Manual Testing
Loop Test: (8 mA / 12mA / 16mA):
Pressing the “Loop Test” pushbutton, will manually test the loop and connected actuators/indicators. The loop test forces the
output and corresponding LED’s to shift from 8 mA to 12 mA (only 962) to 16 mA back to 8 mA. The time delay setting is not
active during testing.
Fault Test (3.6 mA /22 mA):
Pressing the “Fault Test” pushbutton for min 2 s, will manually test the fault output and connected actuators/indicators. The fault
test simulates a circuit failure and forces the output to either ≤ 3.6 mA or ≥ 22 mA. The time delay setting is not active during
t
esting.
Troubleshooting
Problem Action/Indication Solution
No loop signal No LED’s are ON
Check wiring / input power
Check for malfunction (962). See below
No change in output between
wet gap / dry gap
Gap may be plugged by
solids / dense foam
Clean the transducer
Gap is out of reach of liquid Check mounting section and relocate
the unit or check blocking valves.
Chattering output Excessive aeration / Turbulence Introduce a time delay
Check input power
Relocate the switch
If installed horizontally, make sure the
961 transducer gap is oriented in a ver-
tical position as shown in the mounting
section. This allows proper drainage
from the gap, and prevents air bubbles
from accumulating in the gap.
Fault LED is ON (961)
All LED’s OFF (962)
A system fault has been detected Check input power
Press «Loop Test» pushbutton
to identify the problem:
* --- * : 1 flash (red LED)
Check wiring between transducer and
electronics or replace transducer.
** --- ** : 2 flashes (red LED) Replace electronics
*** --- *** : 3 flashes (red LED) The unit senses excessive noise
interference. Check shield connection or
eliminate interference from a walkie-
talkie, radio or other nearby source

chotel electronics can be removed in the field under process conditions. Follow below steps to exchange electronics/trans-
ducer:
Note: Adjust set up of the replacing electronics following the settings of the old electronics (see configuration section)
1. Disconnect power before removing the housing cover
2. Remove power/output wires (a)
3. (Skip step 3 if hygienic housing.) Click out the protection cap of the electronics (b)
4. Remove the 2 bracket screws and slide out electronics (c)
5
. Remove the transducer wires (see Wiring section) (d)
6. Re-assemble following the same procedure in opposite way. Make sure that the tip on the bracket of the electronic block is
seated properly in the corresponding recess in the housing base - (e)

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
t
he 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
Any unit that was used in a process must be properly cleaned in accordance with the proper health and safety standards
applicable by the owner, before it is returned to the factory.
A material Safety Data Sheet (MSDS) must be attached at the outside of the transport crate or box.
All shipments returned to the factory must be by prepaid transportation. Magnetrol will not accept collect shipments.
