the Shuttle® Ultrasonic Level Transmitter.
1: Read this manual carefully.
2: Be aware of the environment at the in-
stallation site. Wear necessary protective
equipment and follow all current safety
regulations.
3: Shuttle® can provide a start signal for
dangerous machinery. Always ensure
that connected machinery and other
equipment are effectively being put out of service (i.e. removal of main
fuses, lock main- and/or security
switches in off position) before commencing setting, fault finding, service
and maintenance work etc.
4: There is a risk of lethal electrical shock
from terminal 1 to 5 and L-N. Be careful
not to touch these while Shuttle® is in
service.
Repair
1: Repair of Ex approved equipment (ul-
trasonic transmitter) must only be made
by MJK or by a service representative
approved by MJK.

Shuttle® measures the level by sending an
ultrasonic signal against the surface and
measuring the delay time of the received
echo.
Although Shuttle® is equipped with a very
advanced system for eliminating measuring
errors, the ultrasonic sensor must - as much
as possible - be mounted so that the ultrasonic signal is not disturbed by liquid being
pumped in or by mixers, ladders or other
installations in the tank.
The liquid surface should also be calm and
without waves and possibly without foam
that may muffle the ultrasonic echo too
much.
Since the ultrasonic beam is extremely
narrow (3 ° - 7 ° depending on the type of
sensor), Shuttle® can be used for measurements in very narrow tanks or wells. This requires that the ultrasonic sensor is mounted
so it points absolutely vertical against the
surface - or the ultrasonic echo will simply
miss the sensor.
Explosion hazardous areas
The ultrasonic sensor is Ex approved in accordance with EN 50021:1999 and can be
mounted in Zone 2 without the need of a zener barrier. Please check local requirements
before installing in hazarduous locations.
The level transmitter (= the electronic
box with display) must not be mounted in
explosive hazardous areas.
Mechanical mounting
Level transmitter
Shuttle® is in NEMA 4X enclosure and can
be mounted outdoors directly on a wall,
a railing or a banister with mounting plate
200240 and universal bracket 200205.
Two things are extremely important when
mounting the ultrasonic sensor: (See also
appendix C!)
1: It should be mounted securely.
2: It should be mounted absolutely vertical.
Use a spirit level in TWO directions.
To ensure a reliable and precise level measurement it
is of vital importance that the ultrasonic sensor points
down absolutely vertical against the liquid surface.
The ultrasonic sensor should be mounted
so the ultrasonic signal has no obstructions
between sensor and surface, i.e. no pipes,
cables, grates etc.
The ultrasonic sensor is equipped with a
nut for bracket mounting. Note the recess
on the nut - it must be fitted safely in the
bracket for firm fixing to the bracket:
For the highest accuracy, the ultrasonic sensor should be mounted as close as possible
to the highest possible level that can occur
+ 14 in. See below:
Min. 14 in (200570,
200640,200660)
Highest pos-
sible level
Min. 32 in (200630)
Max. measuring range:
200570: 45 ft
200640: 35 ft
200630: 75 ft
200660: 30 ft
We deliver two types of sensor brackets that can be
used in almost any installation. The bracket shown is a
The ultrasonic sensor is delivered as
standard with 39 ft of cable. The ultrasonic
sensor can be delivered with up to 300 ft of
cable on order, or the standard 39 ft cable
can be extended to max. 300 ft.
The cable is a special low capacity cable,
so extensions should always
be made with the same type of cable.
On of the most common faults on a Shuttle®
installation is bad or faulty cable connections or using cables that dose not meet the
required specifications.
It is recommended to use connection

When the cable has been cut, the shield
should be mounted in terminal 5 instead
of the black wire !
When the ultrasonic sensor is mounted and
connected correctly, the Shuttle® can be
connected to the power supply.
The keyboard is used only for the initial programming of the Shuttle®, and is therefore hidden
behind the front lid. The keys are marked with symbols indicating their function. The same

When Shuttle® is connected to power for the first time, the
following texts (Choose Sensor Press Enter) will appear
across the display:
Press "Enter" once to select the required sensor type.
Sensor type selection
When "No Sensor" (no S) is displayed, press the 'Up' or
'Down' arrow key to leaf through the different sensor types:
2005xx and 2006xx.
When the required sensor type appears on the display (here:
200570), press "Enter" once.
The sensor type is now registered by the level transmitter,
and "Press Enter" passes across the display to indicate that
you may continue with setting/measuring a level of 0 meter
(nil, empty tank).
Press "Enter" once to proceed with the initial settings.
Notes:
When a sensor type has been selected, the factory settings will have no influence on this selection.
If you choose "No Sensor" (no S), the Shuttle will
invoke the choose sensor menu at start-up. From this
point the correct sensor type can be selected.
At the same moment Shuttle® registers an echo, the zero point is automatically set to the
level that is present in the tank or well.
Furthermore, the mA output is set to 4 mA at the current zero point and 20 mA at a level corresponding to a distance of 14 in from the ultrasonic sensor.

Shuttle® will now indicate the current level in the tank or well
(0 ft immediately after initial startup) and is now in service as
a regular level meter, i.e. without the use of the relays and
the analog output for control / alarm.
The automatic setting of the zero point and the mA output made by Shuttle® during initial
startup may be adequate.
If changes of the zero point read-out and mA output setting should be necessary, and when
Shuttle® is to be used as a pump controller or for level monitoring, an additional 5 settings
should be made. These settings are described in detail on the following pages.
Proceed with set-up in the order listed below:
1: Setting units of measurement See page 17.

With this function Shuttle® learns if there are any disturbances in the well or tank that could appear as a true echo.
Disturbances can result from inlet pipes, the pump installation, a slanted bottom, etc.

practically eliminate the chance of locking on a false echo.
Shuttle® will look for a maximum of 15 echos.

Almost all system errors are due to the echo from the ultrasonic sensor being either too weak
or missing. This is normally caused by incorrect installation of the ultrasonic sensor, a faulty
ultrasonic sensor or by faults on the cable between the ultrasonic sensor and the Shuttle®
level meter. Other factors also have an influence on the ultrasonic level measurement. But
always check first that the ultrasonic sensor is installed correctly and is working properly. See
also the fault finding table on the facing page.
Indications on system errors
First, Shuttle® will indicate that the echo is too weak or missing. After 5 minutes Shuttle® displays 'S.Err', and if one of the relays is set to be activated on a system error, the relay will be
activated after the delay time. At the same time the signal from the mA output will be either
locked on the last known value or provide a preset signal value (3.5 - 20.5 mA). Other valid
error types are temperature errors, internal stack errors and EE-PROM errors (see below).
If the problem disappears, Shuttle® will change back to normal read-out. At the same moment, the relay output set as alarm output will switch back to its normal position and the mA
output will provide a normal signal.
Normal read-out
Shuttle® receives an echo
that has sufficient strength
for a safe and reliable level
measurement.
Too weak or missing echo
The received echo is too
weak for Shuttle® to perform a safe and reliable level
measurement.
System (sensor) error
If echo is still weak after 5
minutes, Shuttle® enters
system error mode and
sends an alarm. Also, relays
configured for pump control
will be deactivated.
Temperature error
Contack an MJK service
representative, if a temperature error appers.
Internal stack error
Contack an MJK service
representative, if an internal
stack error appers.
Contack an MJK service
representative, if an EEPROM error appers.
Power failure
If one of the relay outputs is
set to NC (normally closed),
an external alarm is immediately sent out at power
failure.

The ultrasonic sensor is characterized by a
very narrow spread of the ultrasonic signal
(3 ° - 7 ° depending on the type of sensor),
which makes it possible to use the ultrasonic sensor under very tight conditions, i.e. in
narrow wells or tanks. 80 % of the ultrasonic
signal is concentrated within this area, which
will give a sufficient echo in the far most
cases.
It is required though, that the ultrasonic
signal is not being muffled or disturbed by
gratings, pipes, cables etc., and that the
ultrasonic sensor is not mounted so the
ultrasonic signal is sent too close to a tank
wall or well wall.
The spread of the ultrasonic signal
The illutration to the left shows the spread
of the ultrasonic sensor in conjunction with
the measuring distance, the ultrasonic signal
spread will be 23 in at a measuring distance
of 30 ft.
Acordingly, as the measuring distance increases, the distance from the center line to
a smooth wall should also be increased.

measurement distance. The signal spread
should be increased by 50 - 100 % if the
surface is not smooth!
The values in table 1 assume the ultrasonic
signal is sent along a smooth surface like
a wall or plane without any projections,
joints, butts etc.
If the surface is not smooth or has projections (i.e. joints on prefab elements), the
ultrasonic signal will be impedeaded too
much, and for that reason
the values for minimum distance to wall in
table 1 should be increased with
50 to 100 % !

Measurement in a closed container or tank.
Through pipe for foam protection
When measuring on liquids prone to build
up foam on the surface, it is often necessary
to measure through a pipe, since the build
up of foam rarely will occur inside the pipe.
Under certain circumstances it may be necessary to make adjustments and to make
readings in the following special menus.
It is recommended that only experienced
users and MJK service technicians make
alterations in these menus.
The following menus are not protected with
an access code:
Bar graph read-out
Active measuring range
Response time
Measurement method
mA output value during system error
Calibraton of level readout
Offset level readout
Indication of echo signal quality
Indication of signal amplification

20 mA), the bar graph will increase when the level
decreases and vice versa.
ased to i.e. 4.50 - 9 ft (see next page), the range
of the bar graph will be changed accordingly (all
segments lit at 9 ft and all segments off at 4.5 ft.)
Shuttle®'s measuring range is normally set automatically to
a distance corresponding to the ultrasonic sensor's distance
to zero level + 1.5 ft.
It may become necessary to decrease the active measuring
range so it corresponds to the highest and lowest possible
levels in the well /tank - especially if the ultrasonic sensor is
mounted above a steel grating or an opening in a well cover.
In this example, the Shuttle®'s active measuring range are
decreased from 14 in - 45 ft to 4.50 - 9 ft measured from
the sensor - that is 9.00 ft from the bottom to 4 in below the
grating or cover.

When the level changes, the display read-out will change
accordingly with a pre-programmed delay.
The response time is set to 100 mm/sec. (= 4 in/sec.) from
the factory, which means that an actual level change will not
be shown in the display at a faster rate than 4 in per second.
When measuring on turbulent surfaces, it may become
necessary to increase the response time in order to obtain a
more stable level measurement and also relay function.
Select the desired response time with the arrow keys.

response time for the mA output and the time for
exceeding the set/reset levels.
Shuttle®'s high accuracy is partly obtained by controlling the
strength of the ultrasonic pulse based on the strength of the
received echo. (AP 1)
When performing level measurements on foaming surfaces,
granulate, sludge etc., the received echo is generally so
weak that it would be better to let Shuttle® send out the
ultrasonic pulses with full strength constantly. (AP 2)
Also, when performing level measurements on surfaces with
very rapid level changes, it can be necessary to moderate
the influence of the learning function (see also page 28) to
prevent Shuttle® from locking on false echos. (AP 3)
Select measuring method with arrow keys.
If 'AP 1' is selected, the ultrasonic pulse will be controlled in
accordance with the strength of the received echo.
'AP 1' should normally be selected for fluid applications.
If 'AP 2' is selected, Shuttle® will transmit with full strength
constantly.
'AP 2' should normally be selected for sludge / granulate
applications.
If 'AP 3' is selected, Shuttle® will be better to catch rapid
level changes.
'AP 3' should normally be selected for measuring in sludge
containers, grating matter or other aqueous matter.
This function determines how the mA output should act in
case of a system error.
System errors are most often caused by a weak or missing
ultrasonic echo, but may also occur by failure of the ultrasonic sensor or failure in Shuttle®'s internal circuits.
Select the desired condition with the arrow keys.
The mA output will be locked on the last known value when
a system error occurs.
The mA output will give a fixed signal when a system error
occurs.
Select the desired value (0.35 to 20.5 mA) of the fixed signal
with the arrow keys.
If the distance of the ultrasonic sensor above the surface is
known, it will be possible make a calibration of Shuttle®'s
level read-out.
The calibration will only have influence on the level read-out
- not on relay setpoints for pump control, alarms etc.
Note:Because of the built-in temperature compensation,
Select the desired correction with the arrow keys.
If the learning function has been activated, Shuttle® will
deactivate the learning function and erase the suspicious
levels that were found last time the learning function was
activated.
The learning function must therefore both be started and
reactivated again.
If the relay outputs are configured for pump control, the
relays will be deactivated, but their limit settings will not be
erased. Also, delay settings and other settings will not be
erased.
it is important that the ultrasonic sensor has the

This menu is used to indicate the strength of the received
ultrasonic echo.
If there are frequent system errors (see page 32), this
function can be used to check if the ultrasonic echo is being
weakened too much under the current working conditions
- i.e. foam, waves etc.
There are no specific limits indicating that the echo is too
weak, since it depends highly on the current working conditions. Please contact MJK for advice.
The strength of the received ultrasonic echo is displayed
immediately.
(The strenght is shown in percent.)
This menu is used to display the amplification level of the
received ultrasonic echo. The function can give an indication
og the strength of the received echo.
If the amplification level is low (below. 20 dB), the echo
strength is good and vice versa.
A high amplification level (max. 50 dB) indicate that the
ultrasonic echo is weak (foam or waves).
High amplification may in certain situations create other
problems with electrical noise from other equipment at the
installation site.
The amplification level is displayed immediately.
(The level is displayed in dB)
This menu is used to display the longest time period during
which Shuttle® has been missing an acceptable echo, and
also how many days has passed since this occurred.
The longest time period that Shuttle® has been missing an
acceptable echo is displayed immediately.
(In seconds.)
Next, the number of days since the occurrence is displayed.
The longest period with echo failure will be erased after 14
days.
All settings - except calibration of the level measurement
- made after initial startup will be reset to factory settings
with this function.
The zero point setting will also be adjusted to the immediate
level in the well / tank. Furthermore, the mA output is set to
4 mA at the current zero point and 20 mA at a level corresponding to a distance of 14 in from the ultrasonic sensor.
