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 specialconstruction of two separately screened twisted pairs, designed to meet electromagnetic compatibility regulations.The cables can be extended up to 100 metres, but sho...

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 pairsOne pair is connected to the TX (transmit) group and the other to the RX (receive) group. The sensors...

IP258 15 TRIGGER INPUTS There is trigger input D1. This can be used to control desludge and other functions see programming section. Thedigital trigger input is connected as shown below: A voltage greater than 2V on Terminal 8 (D1) causes trigger input 1 to be active. This can be achieved byconnecti...

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 ofoperation. The parameters are accessed using the keypad, by...
