T ake care in handling the pipe section. In particular do not damage the cable or the hose protection for the cable where it enters the sen[...]

IP258 12 4. 4 SENSOR CABLES The ultrasonic drive signals on the sensor cables are normally at 1MHz and 3.3MHz. The cables are a special construction of two separately screened twisted pairs, designed to meet electromagnetic compatibility regulations. The cables can be extended up to 100 metres, but should use the same cable type, available from Mob[...]

IP258 13 4. 6 ELECTRICAL CONNECTIONS All field wiring connections are accessible by removing the lower lid, which is secured by two screws. Note that it is the responsibility of the installer to observe all local regulations and approval requirements, and to use cable to suit the environmental requirements of the particular application. Obtain and [...]

IP258 14 SENSOR CONNECTIONS The sensor connections are on the left side of the terminal enclosure. Each sensor has two screened twisted wire pairs, either as one dual pair cable, or two separate pairs One pair is connected to the TX (transmit) group and the other to the RX (receive) group. The sensors are symmetrical so either of the pairs can be c[...]

IP258 15 TRIGGER INPUTS There is trigger input D1. This can be used to control desludge and other functions see programming section. The digital trigger input is connected as shown below: A voltage greater than 2V on T erminal 8 (D1) causes trigger input 1 to be active. This can be achieved by connecting to terminal 10 (5V) via an external switch o[...]

IP258 16 5. 0 PROGRAMMING 5. 1 The operation of the MSM400 is controlled by means of programmable parameters. These are stored in memory and may be set by the user to define variables such as calibration scale factors, set points, and modes of operation. The parameters are accessed using the keypad, by means of a menu system as shown below . (Param[...]

IP258 19 6. 2 RECHECKING ZERO It is recommended that the zero is checked regularly . The frequency of re-calibration is dependent on the process. However , it is suggested that this be done at least every 6 months. CALIBRA TION METHODS AUTO CAL 6. 3 AUTO CAL - ZERO SETTING PROCEDURE AUTOCAL is a simple step by step calibration routine in which the [...]

IP258 20 The display will show the following. SET ZERO 0 In clear liquor 0 please wait After a few seconds the display will show the following. SET ZERO 0 In clear liquor 0 Press ENT to set 23.1dB 26.2dB The two dB values at the bottom of the screen are the zero values for the operating frequencies of the sensor (1MHz and 3.3MHz). Once the ENT key [...]

IP258 21 After a few secnds the display will show the following. SET SPAN 0 In sample 1 0 Press ENT to set 33.6dB 44.2dB The bottom line of the display shows the attenuation caused by the sludge. During a desludge these readings will fluctuate due to random variations in the sludge density . When the readings are reasonably stable press ENT at the [...]

IP258 22 6. 6 MAXIMUM % SOLIDS T o complete the calibration and to enable the system to automatically select the optimum frequency of operation., it is necessary to set the maximum % solids that the system is required to measure. In the AUTOCAL Menu, select ‘Max % Solids’ (P 160) and enter the value required. If the maximum % solids are low the[...]

IP258 23 Under stable operating conditions, the objective is to record the MSM400 attenuation figure, and immediately take a sample of the slurry present between the sensor faces.This is then analysed in the lab, to derive the solids %, and this % value is later linked to the previous ultrasonic attenuation. The objective is to take three separate [...]

IP258 24 7.0 PROGRAMMING THE MSM400 FUNCTIONS DUTY (MODE) DESLUDGE MODE. There are several methods of starting, stopping, overriding and stopping early a de-sludge operation. The desired options can be selected in the SETUP – DUTY (Mode) – DESLUDGE menu. The following table explains the various options. (PV = process value i.e. % suspended soli[...]

IP258 25 Starting desludge This is controlled by the “Start on” function in the DESLUDGE menu. This should be set to “T ime”. Cycles will begin at “Start T ime 1” and repeat at intervals “Interval 1” until “Start T ime 2”. After this, cycles will repeat at intervals “Interval 2”. This allows desludging to be done at differen[...]
