MonoScan Setup & Configuration


MonoScan supplied with preprogrammed default settings, making it ready for immediate

use.

Main setting-up steps 0 – 5 Pr 00 – Flow measurement

(MonoScan O)This program enables you to

selectpreset weir/flumes.Note: this function will be

available only for Open Channel unit.

Setup

MonoScan 2 wires


Pr 01 – Reset reset the unit (keeps the last parameters), same as on/off

Pr 02 – Tank height enter the correct height (from sensor to bottom)

Setup


Pr 03 – Defining interfering

signals (Scan Distance process)

“Static interference” is a well

known phenomenon in ultrasound

technology.

Use Scan Distance function to

“map” your tank from these

obstacles and to memorize the

interfering signals.

MonoScan 2 wires

Setup


MonoScan can locate and store up to 7 obstructions.

After storing 7 interference signals the memory act as FIFO (first in first out), the 7th signal will erase the first signal and so on.

Note: Each obstruction will extend

the calculation time. Defining interfering signals

is done while the tank is empty.

Setup


Clear stored interferences When entering Pr.03, you

can either select Search to locate acoustic interferences, or Clear to delete stored interferences.

Setup


Pr 04 - 4 mA Pr 05 - 20 mA

The 4mA can be defined for Level, Distance or Flow measurements. This definition will be applicable for 20mA values, in Pr.05.

MonoScan 2 wires

Setup


When setting 4mA and 20mA for Level measurements, Pr.04 and Pr.05 will be configured for level values.

When setting 4mA and 20mA for Distance or Flow the values will be in Distance or Flow).

Extra Features

Pr 06 Low / High dynamic Define whether high or low reading speed :

SE 0 - 80cm/minute (low dynamic)SE 1 - 1.5m/minute (high

dynamic)SE 2 – rapid changes (fast

dynamic 2m/min)Note: Pro 06 is available in models L/O, while S uses low dynamic as default.

Setup


Pr 08To select whether to display distance (from surface) or the level (of the surface) d000 represents

distance reading L000 represents level

reading

Pr.09 – Gas Compensation. This program enables you to

compensate for sound velocity in different types of gasses, provided the sound velocity is fixed.

You can enter the appropriate factor for each type of gas listed on the ‘Gas Table’ in the User Manual.

For example the sound velocity in air is 331.6 m/sec and for Ethanol (C2H3OH) 235.4 m/sec, therefore a factor of 235.4 /331.6= 0.71 .

Note: Since there are several gases in the tank, air density must be calculated

Setup

Gas Compensation – Volume calculation This program enables the user to calculate volume in a linear

tank (cylindrical etc). PR09 factor is multiplied with the measurement value giving a volume up to 1500 (maximum displayed value).

For example tank height = 1.5m Volume factor = 3 Maximum volume = max T.H. X Volume factor = 1.5 X 3 = 4500

Maximum Gas factor = 10 Volume is calculated linear.

by manufacturer.


22mA Error Signal Indications

“F.F.F.F” - Whenever the level reaches up to 10cm inside dead zone or overflow occurred, “F.F.F.F” will appear on the MonoScan’s display.

“E.E.E.E” - Whenever the echo is not received by the transducer because of empty tank or when the measured distance is greater than permitted, “E.E.E.E” will appear on the MonoScan’s display.

MonoScan 2 wires Setup


Enable/Disable 22mA error signal indications, such as: Near Zone (F.F.F.F) and Lost Echo or empty (E.E.E.E).

Default value is disable. In order to enable it, Enter

0016 in Pr.02.

Device’s version.

Enter 0017 in Pr 02. After entering this code, the

screen Addr (Version) will be displayed.

Enter 0013 in Pr 02. After entering this code, the

screen Addr (sub Version) will be displayed.

Setup


Shift Blocking Distance (SBD)

This function enables you to enlarge the Dead Zone and is applicable for installations requiring extension pipes or nuzzles positioned above the application level.

SBD is limited to 1.5m/4.9ft. In order to access this

function, enter 0001 in Pr 02.

Setup


Pr 00 – Flow measurement (MonoScan O)Includes 17 types of Flume/Weirs, each of them is offered at several Sizes.The measured units can be displayed as either GPM or M3 Per hour.The methodology used when setting up open channel:X – Particular flume/weir typeE/U – European/American standardYY- Specific flume/weir dimensions

disconnected Contact manufacturer for further instructions

E555 – Power supply problem Make sure your power supply corresponds to Solid specification. If problem persists, replace the power supply

Troubleshooting


A combination of three 8 and one 1 may occurred either due to shortage or when two pads pushed simultaneously.

8188 Back 8818 Next 8881 Enter 1888 Escape

Check for any visual damage on Pads.

MonoScan 2 wires

Troubleshooting


8888 will appear for a few seconds after restart. If it last more than a few seconds it may be due to the following reasons: Power supply’s voltage is

too low “Load Resistor”

resistance is too high or not necessary at all

Random Impulse which cause automatically self restart
