Pointek ULS 200
Note: Pointek ULS 200 is to be used only in the manner outlined in this instruction
manual.
Pointek ULS 200 is an ultrasonic based process level switch providing high or low switch
action on liquids or solids. The process part (sensor) is Tefzel®or Kynar Flex®, allowing it
to be used in a wide variety of industries.
Pointek ULS 200 contains an ultrasonic transducer and temperature sensing element. The
transducer emits a series of ultrasonic pulses. Each pulse is reflected as an echo from
the material and sensed by the transducer. Pointek ULS 200 processes the echo using
Milltronic's proven Sonic Intelligence®techniques. Filtering is applied to help
discriminate between the true echo from the material and the false echoes from
acoustical and electrical noises and agitator blades in motion. The time for the pulse to
travel to the material and back is temperature compensated and then converted into
distance for display and relay actuation.
The Pointek ULS 200 is an excellent primary detection device, but should not be used as
a backup device. For backup devices use a contacting technology such as the Pointek
CLS 200. The optional sanitary version affords quick removal and ease of cleaning as
demanded by the food, beverage, and pharmaceutical industries.

Operation
Start Up
With the Pointek ULS 200 correctly installed (or aimed at a wall 0.25 to 5 m away), apply
power and observe the Pointek ULS 200 start up sequence. The unit will cycle through the
following screens:
1. Lighting of all possible LED values
2. Product revision number
3. Product model number
4. Run mode
The display and operation sequence arrives within a few seconds at the run mode, which
is the measurement of the distance from the transducer face to the material level in the
units indicated. Full instructions on setting up the unit are found at Applications on page
13 and Adjustments on page 19.
Quick Start
Use this setup method if you have a basic high/low application and you are setting up the
unit in a place where you can easily adjust the measured distance.
The Pointek ULS 200 relays are preset as: relay 1 = alarm 1, high alarm at 0.25 m
relay 2 = alarm 2, low alarm at 5.00 m
To change the setpoints by reference method, set the material or target to the distance as
displayed. Press the ` 1 /
setpoint function and value. By pressing the alarm key a second time, the Pointek ULS
200 changes the setpoint to the value currently being measured.
After viewing or changing the setpoint, the Pointek ULS 200 reverts to the run mode.

High Level Alarm Switch
This application uses Pointek ULS 200 to provide an alarm output, high and/or high-high
alarm, when the process material rises to a high level. The device range applies to its
switching capability, and not the process range of the material.
It is therefore common to apply the switch on vessels where the material is normally
below the unit's range. Under such a condition the Pointek ULS 200 loses echo, and if
prolonged, defaults to fail-safe operation. As this would be a normal occurrence, it is not
advisable to select the fail-safe high option.
If the high level switch is being applied to a vessel within the 3 / 5 m range, a loss of echo
and ensuing fail-safe condition would not be a common occurrence. The fail-safe default
would then be at the user's discretion.

High / Low Level Alarm Switch
This application uses Pointek ULS 200 to provide high and low level alarms. The device
range applies to its switching capability, and not the process range of the material. As
such the low and/or low-low level setpoints must be within the device's range (3 / 5
metres).
If the material can fall below the unit's range, the Pointek ULS 200 loses the echo, and if
prolonged, defaults to fail-safe operation. The fail-safe default should be set to suit the
application.

This application uses the Pointek ULS 200 to provide one or two low level alarms. The
device range applies to its switching capability, and not the process range of the material.
As such the low and / or low-low level setpoints must be within the device's range (3 / 5
metres).
If the material can fall below the unit's range, the Pointek ULS 200 loses the echo,
and if prolonged, defaults to fail-safe operation. The fail-safe default should be set to

Dual Pump Control
This application uses Pointek ULS 200 to provide a control output when the process
material rises to a high level. The device range applies to its switching capabilities, and
not to the process range of the material. As such, the level setpoints must be within the
device’s range (3 / 5metres).
Typically, wet wells are used to temporarily hold storm and/or waste water. When the
water surface reaches a high level setpoint, the wet well is pumped down. The process
material will be pumped down by the deadband value to another setpoint where the
control will turn off.

Pump Control with Level Alarm
This application uses the Pointek ULS 200 to provide pump control and one level alarm.
The device range applies to its switching capability, and not the process range of the
material. As such the low level setpoints must be within the device's range (3 / 5 metres).
If the material reaches a control setpoint, the well is pumped down or up respectively. If
the material reaches an alarm setpoint, the alarm will sound until the material moves
beyond the deadband value.

Setpoints
The setpoints can be set where reference levels, either from the material in the vessel or
from a target, cannot be provided. This method can also be used to trim the output levels
obtained by the Reference Method (Quick Start).
The setpoints are referenced from the face of the sensor. They should not be set at or
above the blanking value, or at or below the range limit.

Relay Delay
Adjust the time delay, in seconds, from when the material reaches the relay level and the
relay is actuated. If the material level withdraws from the setpoint level, the delay is reset
to 0.
The set time delay applies to both relays and all functions except `Loss OF Echo'.
Factory setting: 0 seconds.

Relay Deadband (Reset)
Deadband (sometimes referred to as hysteresis) prevents relay chatter due to material
level fluctuations at the set point. These fluctuations are often waves or turbulence on a
fluid's surface caused by agitators in the tank.
Once a relay is tripped the detection level must move beyond the deadband value before
it is reset. The direction in which the deadband is measured depends on the application
of the relay. If the relay is for a high state then the deadband is measured below the set
point. If the relay is for a low state then the deadband is measured above the set point.
Refer to the diagram below.
Deadband 1 is used for Relay 1 and Deadband 2 is used for Relay 2.

Blanking
Blanking is used to ignore the zone in front of the transducer where false echoes are at a
level that interfere with the processing of the true echo. It is measured outward from the
sensor face. The minimum recommended blanking value is 0.25 m (0.82 ft) but can be
increased in order to extend the blanking.

Range Limit
The range limit is the distance at which measurements are ignored. Generally this refers
to the bottom of the container being measured. If a measurement is detected beyond the
range limit it results in a Loss Of Echo (LOE) reading. The result of this reading is
determined by the Fail-Safe Mode, see page 25 for more information.

Speed of Response
The speed of response adjustment allows the user to collectively set a number of
operating parameters.
measurement is the limit to which the Pointek ULS 200 is able to keep up with
response: rates of change.
If the Pointek ULS 200 measurement cannot keep up with the
rate of level change, set the adjustment from `1' to `2'.
If the Pointek ULS 200 still cannot keep up with the rate of
level change, set the adjustment option to `3'. Avoid
choosing an option that is too fast for your application.

discrimination: and the material (target) surface.
filter: discriminates between false echoes from acoustical
and electrical noise and the material (target) surface.
fail-safe timer: establishes the `Waiting' period from the time a loss
of echo or operating fault condition starts until the
fail-safe default is effected.

Fail-Safe Mode
In the event that a loss of echo condition exceeds the fail-safe timer (speed of response
variable), `?' appears in the display; and if a relay is assigned to `LOE' (alarm function
option), it is engaged. This function must be used with the Output Function on page 22.

Fail-Safe Timer
The fail-safe timer allows the user to vary the waiting period from the time of a loss of
echo or operating fault condition begins, until the fail-safe default is effected. The waiting
period is adjustable from 1 to 15 minutes, in 1 minute increments.
Note: The fail-safe timer will default to settings determined by the speed of response
(see page 26). If a different value is desired, the fail-safe timer should be adjusted after
the speed of response is set.
Units
The units of the measurement reading can be selected as follows:
1 = metres, m
2 = feet, ft
The selected units are also applicable to the `Blanking' and `Relay' adjustments.

Troubleshooting
The echo is not reliable and Pointek ULS 200 is waiting for a
valid echo before updating the measurement.
Probable causes are: Remedy
material or object in contact with
sensor face
Pointek ULS 200 is not perpendicular to
the material surface
change in level too fast adjust speed of response
material out of range
foam on liquid surface
too much dust or interference from
material filling
high level of vibration in the
mounting structure
material inside blanking zone or
below range limit
lower material level or raise Pointek
ULS 200
check Pointek ULS 200 mounting
if angle of repose is too steep, angle
Pointek ULS 200 mounting
acceptable on some high level switch
applications
mount Pointek ULS 200 via stilling well
or pipe
relocate Pointek ULS 200
relocate Pointek ULS 200 or limit
vibration
adjust blanking or range limit
Fail-safe default after prolonged Loss Of Echo.
Investigate the probable causes listed above.
