Pulsar IMP Quick start guide

Brand: Pulsar

Model: IMP

Type: Quick start guide

Pulsar IMP is a quality system developed with the latest digital ultrasonic technology for measuring levels and volume of liquids, slurries, and solids. It provides non-contacting level and volume measurement with 2 user-defined relays and comes standard as both 2-wire and 3-wire configuration. Intrinsically Safe loop powered version is available with ATEX approval for hazardous areas. With its advanced features, IMP has various applications, including:

Level measurement in tanks, silos, and other vessels
Volume measurement in tanks and other containers
Control of pumps and other equipment based on level or volume

Level measurement in tanks, silos, and other vessels
Volume measurement in tanks and other containers
Control of pumps and other equipment based on level or volume

LIQUIDS and SOLIDS

• Mount the IMP away from any obstructions, falling

water/solids, rough walls, pumps, switches, etc…

• Visualize looking down the echo path of the IMP and

seeing a nice clear shot (2’+ dia.) to the very bottom

during fill and empty cycles.

• Ensure the maximum level does not come within the

minimum blanking distance.

• Confirm the inside of the standpipe is smooth and does

not have any protrusions at the weld.

• Increase the blanking distance 2+ inches beyond the

end of the standpipe where it attaches to the vessel.

• Typically, mount the IMP 1/2 the tank radius.

• Be careful screwing the IMP into a NPT thread and do

not over-tighten.

(Call Pulsar Technical Support for Special Service

Passcode and Instructions 850-609-1777.)

MOUNTING

• Do not over-tighten the threads! Try loosening if level is

reading very high.

LIQUIDS

• Dome top tanks will require First Echo Algorithm.

• If reading false level, use P21 and set true distance.

SOLIDS

• Consult factory if the silo is dusty—we may need to up-

grade to a stronger system.

• If reading false level, use P21 and set true distance.

• If acoustically noisy, change to Largest Echo Algorithm.

IMP PC SOFTWARE

• Warning… in 2-wire mode, inserting the RS232 cable will

result in automatic 20mA output.

Congratulations on your purchase of a

Pulsar IMP - the low cost integral solution!

This quality system has been developed with the

latest digital ultrasonic technology for liquids,

slurries, and solids. No more noise and beam

angle problems. Also, no handheld programmer

or software required.

It provides non-contacting level and volume

measurement with 2 user-defined relays. Comes

standard as both 2-wire and 3-wire configuration.

Intrinsically Safe loop powered version available

with ATEX approval for hazardous areas.

IMP WIRING

2– wire (I.S. version must use barrier) 3– wire (relays can be used)

PROGRAMMING

1. Enter Program Mode (Passcode is 1997)

( press and hold each button until the dash appears)

To Program a Relay (pg. 27 of the manual)

Choose “Relay Type” (P210, 220)

0=Not in Use 1=Alarm 2=Control

(Alarm=de-energize ON and energize OFF, Control= is opposite)

Choose “Relay Function” (P211, 221)

0=Off 1=Level 4=Loss of Echo

Choose “Relay Setpoint 1” (P213, 223)

This is the ON setpoint.

Choose “Relay Setpoint 2” (P214, 224)

This is the OFF setpoint.

(no setpoints are required when “Loss of Echo” function is used)

To go to Run Mode, follow Step 3.

3. Calibration is done, go into Run Mode!!!

2. Choose “APP” (pg. 25 in manual)

Choose “Mode of Operation (P100)”

1=Distance 2=Level 3=Space 4=Volume

Choose “Measurement Units (P104)”

1=meters 2=cm 3=mm 4=feet 5=inches

Choose “Empty Level (P105)”

=distance from the transducer face to empty level (bottom of

vessel/pump station) - automatically sets 4mA

Choose “Span (P106)”

=distance from empty level (bottom of vessel) to 100% level

- automatically sets 20mA

Choose “Near Blanking Distance (P107)”

=distance from transducer face that is not measurable (can be

increased to blank out obstructions)

Choose “Far Blanking Distance (P108)”

=distance (in %) beyond Empty Level that is measurable

“rL”

Press both simultaneously,

“PASS” will display briefly,

then “0000” will appear.

For “1000”

For “1900”

For “1990”

For “1997”

This is the “Enter” button. Use the

“Enter”, “Up”, and “Down” buttons to

program the following parameters:

This is the “Esc” button. Use the “Esc”,

“Up”, and “Down” buttons to scroll

through the various categories:

“APP” (Application) “rL” (Relays) “Vol” (Volume)

“DisP” (Display) “LOOP” (mA Output)

“Cop” (Compensation) “StA” (Stability)

“SyS1” (System) “tESt” (Test) (scrolls back to APP)

“run”

Program Relay 1 (P210 - P214) and

then program Relay 2 (P220 - P224)

To Troubleshoot a false echo (pg. 40 of the manual)

To go to Run Mode, follow Step 3.

“SyS1”

Displays “P921”.

Displays “P021” (Get out of Jail Free Card).

Enter the true distance from the transducer

face to the material level.

This will map out all false echoes and store

the information permanently.
