Pointek ULS 200
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 / ↑‘or ` 2 / ↓' key. The display responds by displaying the current
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.

Applications
Pointek ULS 200 is designed for use as a process level switch. The local display is used
only as an aid during start up. The instrumentation interface is comprised solely of the
two relay outputs. Switching applications are based on the relay functions adjustment.
The outputs can be set to function in the desired 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.
Application Adjustments

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.

Low Level Alarm Switch
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
suit the application.

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.
