3 IP2046/IM Nov 2006 1.0 Introduction The MSP400 ultrasonic level transmitter is designed to be mounted above a liquid and will measure the distance to the liquid surface. When programmed with details of the vessel, sump or open channel, the MSP400 will compute level, contents or flow and give a 4-20mA signal proportional to the chosen variable.
4 IP2046/IM Nov 2006 2.2 Pressure Equipment Directive The MSP400RH transmitter does not fall within the PED definition as enclosing a pressurised fluid, so is therefore outside the scope of the Directive. Accordingly , the Declaration of Conformity does not list the Pressure Equipment Directive.

6 IP2046/IM Nov 2006 3.0 Installation Important safety notice : The MSP400 is designed for safe area use only , and must not be installed in a hazardous area, even if the power is supplied through a barrier device. General a. Installation must be carried out by suitably trained personnel in accordance with the applicable code of practice.
7 IP2046/IM Nov 2006 • If the transmitter is mounted in an enclosed tank, avoid mounting the transmitter in the centre of the tank roof as this could act as a parabolic reflector and create unwanted echoes. Avoid applications where heavy condensation could form on the transducer face.
8 IP2046/IM Nov 2006 It is important to note that the bottom reference of the transmitter should be related to the centre of the invert of the primary device, NOT the distance to the channel bottom directly below the transmitter . 3.1.3 In-tank effects • Stirrers or agitators can cause a vortex.
9 IP2046/IM Nov 2006 • The liquid surface at the point of measurement must have a stable, smooth surface and uniform approach velocity . It must not be affected by baffles, foam, hydraulic jumps or any other object likely to cause flow disruption.
10 IP2046/IM Nov 2006 3.2 Mounting the transmitter above the liquid surface. A 2” thread is provided to mount the transmitter . The user should check the thread form, which will be either 2” BSPT (MSP400RH-B28) or 2” NPT (MSP400RH-N28). The thread form is clearly marked on the hexagon of the transducer body .
11 IP2046/IM Nov 2006 3.3 Wiring The transmitter is supplied with cable gland suitable for cable sizes 4-8mm diameter . T erminal 1 : +24V dc 2 : 0v dc 3 : RL1 (SPST) 4 : RL1 (SPST) 5 : RL2 (SPST) 6 :.
12 IP2046/IM Nov 2006 3.3.3 Relays The MSP400RH transmitter has 2 integral relays which may be used for control purposes. These relays are light duty and should be used as signal relays only , with control functions being performed by external control relays.
13 IP2046/IM Nov 2006 4.0 Commissioning, programming and operation The MSP400 operates from a menu of parameters, each held in a specific memory location within the instrument. The memory locations may be pictured as a matrix, and the user navigates to each parameter to programme the instrument using ↓ and → steps.
14 IP2046/IM Nov 2006 4.2 Power up On power up, the MSP400 will take a few seconds to initialise. The display will run through a set-up routine, first illuminating all display characters then showing the software revision number .
15 IP2046/IM Nov 2006 4.4 Setting up for the chosen application - the Main Menu. Refer now to the main menu structure chart in Appendix A. It is important to note that MSP400 programming is most easily accomplished by first selecting the duty the transmitter is to perform.
16 IP2046/IM Nov 2006 4.4.2 Selecting the units of measurement Screen display: unitS Factory default setting: MSP400RH-B28 m MSP400RH-N28 ft i) Note that the factory default units of measurement are dictated by the model type, which may be Imperial (ft) or Metric (m).
17 IP2046/IM Nov 2006 4.4.3 Setting the correct bottom reference Screen display: b.rEF Factory default value: MSP400RH-B28 11 MSP400RH-N28 36 The MSP400 leaves the factory with the bottom reference pre-programmed to the maximum range of the instrument, either 11m or 36ft.
18 IP2046/IM Nov 2006 4.4.4 Selecting the correct Profile algorithm. Screen display: ProF Factory default value: Linear This selection is offered only if the user has chosen a duty of Flow or Contents, or is shown when manually navigating the main menu - ignore if duty chosen is Level or Distance.
19 IP2046/IM Nov 2006 Note: The complete range of options is displayed, regardless of the duty selected earlier . e) Once the desired profile is shown (flashing) on the display , press the blue button → to select this option. It will now stop flashing.
20 IP2046/IM Nov 2006 If the profile chosen is any other contents profile, press the red button ↵ to save the profile to memory and automatically scroll on to the next main menu option “Cont @ max”, Refer to Section 4.4.9. 4.4.5 Power factor for the chosen flow law .
21 IP2046/IM Nov 2006 T o edit the scale factor a) Press the blue button → to enter the “SCALE” menu and to display the current scale factor in use.
22 IP2046/IM Nov 2006 4.4.8 Maximum flow entry Screen display Flo @ max Factory default value 1.000 This selection is offered only if the user has chosen a duty of Flow which requires entry of the max.
23 IP2046/IM Nov 2006 4.4.10 Setting the 4mA point Screen Display: 4 Factory default value: 0.000 Enter the value of the PV which you require to be signalled by 4mA The 4mA point may be set above or below the 20mA point to suit the monitoring or control equipment.
24 IP2046/IM Nov 2006 4.4.12 Setting the damping applied to the output Screen display d Factory default value 3 The damping value entered is actually a time constant in seconds which is applied as smoothing to the displayed PV and current output. A new value may be entered up to a maximum value of 9999 seconds.
25 IP2046/IM Nov 2006 T o change the output current action on alarm condition: a) Press the blue button → to enter the alarm action menu and to display the current selection.
26 IP2046/IM Nov 2006 4.4.15 Setting the 4 and 20mA levels using actual liquid levels in the tank Screen display (SEt 4 & SEt 20) Factory default value Hold If you have already programmed the 4 and 20mA levels as above, you do not need to enter this menu.
27 IP2046/IM Nov 2006 4. 5 Diagnostic data. See also Appendix A2. The MSP400 can display useful diagnostic data which can aid setting up and fault finding. T o aid interpretation of the data presented, the data will alternate with suitable text to remind the user what data is being displayed.
28 IP2046/IM Nov 2006 4. 6 Loop T est : See also Appendix A3 “tESt” The MSP400 has the facility to cycle through it’s programmed operating range without any change in the liquid level, causing the current output and relays to cycle through their normal operation.
29 IP2046/IM Nov 2006 4. 7 Engineering Set-up menu : See also Appendix A4 “Eng” The proficient user is able to fine tune operation of the MSP400 if site or application conditions are unusual.
30 IP2046/IM Nov 2006 4.7.2 Setting the Lost Echo T ime Screen display “LE” Factory default value 900 The lost echo time is the time in seconds which the MSP400 will wait before taking the lost echo action as described in 4.4.13. A new value may be entered in the range 0 to 9999.
31 IP2046/IM Nov 2006 T o edit the dead band: a) Press the blue button → to enter the dead band menu and to display the current value in use. If this is correct, press the red button ↵ return to the main menu.
32 IP2046/IM Nov 2006 4.7.5 Setting the Pulse repetition frequency Screen display “Pr f” Factory default value: 1.0 The rate of pulses transmitted by the MSP400 is set at a factory default value of once per second. The MSP400 may be set to transmit faster or more slowly at selected repetition rates between 0.
33 IP2046/IM Nov 2006 4.7.7 Setting the Spike rejection Screen displ ay “SPi” Factory default value: 0 (disabled) In applications with high levels of acoustic or electrical noise, a spike could incorrectly trigger the echo detection system.
34 IP2046/IM Nov 2006 If the new temperature is incorrect, the edit sequence can be re-started by pressing the blue button → again. If the temperature is correct, press the red button ↵ to save the new value to memory and automatically scroll on to the next main menu option: The next option will be “t.
