High – Low Level Failsafe selection:
In
« Hi » position, the process relay will de-energize (report alarm) when the transducer is wet.
In «Lo» position, the process relay will de-energize (report alarm) when the transducer is dry.
Fault selection:
The echotel 961 is equipped with a malfunction relay separate from the 5A DPDT process relay. The separate or joined oper-
ation of both relays can be selected :
I = in case of a malfunction, only the malfunction relay will de-energize. The process relay will only de-energize in case of a
process alarm
J = in case of a malfunction, both the malfunction relay and the process relay will de-energize
The Echotel 962 is equipped with a malfunction relay separate from the two 5A SPDT process relays. In case of a malfunction,
both the malfunction relay and the process relays will de-energize. The operation of the two process relays can be selected:
L (level control) = the two relays operate independent and will be de-energized when the corresponding tranducer gap is
immerged/dry (following Hi/Lo setting)
P (pump control) = the two relays operate in a latched mode, allowing to perform an automatic fill or drain pump control func-
tion in between the 2 transducer gaps. onsult below tables for proper indication and function.
Time 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.
961 - Relay/ LED Indication:
When «WET» (wet LED): OFF = transducer gap is dry / ON = transducer gap is immerged
When «LEVEL» (level LED): ON = relay is energized / OFF = relay de-energized

Manual Testing
Level Test: (process relay(s)):
Pressing the “Level Test” pushbutton, will manually test the process relays and connected actuators/indicators. The level test
forces the relay(s) to change from a de-energized to an energized status and vice versa. The LED’s will be ON/OFF corre-
sponding (see tables in the configuration section). The time delay setting is not active during testing.
Malfunction Test (malfunction relay):
Pressing the “Malfunction Test” pushbutton for min 2 s, will manually test the malfunction relay and connected actuators/indi-
cators. The malfunction test simulates a circuit failure and forces all relays to de-energize. The «MALF» LED will turn OFF and
the «FAULT» LED ON. The time delay setting is not active during testing.
Troubleshooting
Problem Action/Indication Solution
No output signal No LED’s are ON heck wiring / input power
heck for malfunction (962). See below
No change in output between
wet gap / dry gap Gap may be plugged by solids / dense foam lean the transducer
Gap is out of reach of liquid heck mounting section and relocate
the unit or check blocking valves.
hattering output Excessive aeration / Turbulence Introduce a time delay
heck 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 A system fault has been detected heck input power
heck wiring between transducer and
electronics or replace transducer.
Press «LEVEL TEST» test pushbutton
to identify the problem:
* --- * : 1 flash heck wiring between transducer and
electronics or replace transducer.
** --- ** : 2 flashes Replace electronics
*** --- *** : 3 flashes The unit senses excessive noise
interference. heck shield connection or
eliminate interference from a walkie-
talkie, radio or other nearby source

REPLACEME T PARTS
Replacing electronics/transducer
Replacement parts
Echotel electronics can be removed in the field under process conditions. Follow below steps to exchange electronics/trans-
ducer:
ote: 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.) lick 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)
