The MultiTrode MTI liquid level monitoring and control system was developed to provide a solution for interfacing to building management systems and town water/sewerage systems. The system can directly control operation of pumps and provide level indication at the site, as well as at up to four remote locations, using 0-0V or -0m current loop. Until the advent of this MultiTrode system, these facilities had not been economically practical for hydraulic services in high-rise buildings.

5 Introduction The MTI is a conductive liquid level indicator and controller which continuously monitor liquid level in order to control the operation of up to 0 appliances. It will work in the following modes: Fill (harge) mode: Filling a tank Empty (ischarge) mode: Emptying a tank In a standard installation, the liquid level is sensed via a MultiTrode multi-sensored probe. Individual sensors can be used in installations, if desired. Ten output relays control pumps, valves and, in addition, there are -0m and 0-0V stepped analogue outputs for use with variable speed drives, chart recorders etc. n MTRI can also be connected to the -0m output of the MTI to remotely indicate level, and control appliances at a distance of up to several kms from the MTI. front-panel LE indicator lamps show level and power supply status. The front panel allows for placement of labels to indicate at which point devices will activate. -way IP switch on the rear panel provides for the setting of four sensitivities and four time delays. In addition, a 0-way IP switch allows for the setting of the relays as Normally Open or Normally losed.. Front Panel MULTITROE INITOR ONTROLLER HI LRM STNY LG LE PUMP OFF LO LRM MTI POWER ON The MTI has LE s. The bar graph on the lefthand side indicates level, whilst the green LE in the upper right-hand corner indicates power availability. There is a slot located next to the bar-graph, that is used for the placement of labels to indicate at what levels pumps and alarms operate. Up to 0 labels can be placed here.

This section describes the function of each terminal and IP switch. Figure - MTI Indicator ontroller ack Panel MTI / MTRI Manual R Page of 6

6 Function IP Switches n important step in the commissioning of the controller is to preset the positions of the rear panel IP switches. This will set up the basic operation of the unit to match the installation. The following tables show the switch functions.. Timer & Sensitivity IP Switches This section of the back panel is black. see fig # SELET FUNTION Figure The MTI should be switched off prior to altering the IP switch settings. SW Function Position escription Timer Instantaneous actuation when level reaches sensor. Timer Time delay on actuation approx. seconds. Timer Time delay on actuation approx. 0 seconds.

7 . Output Relay IP Switches This section is black in colour on the rear panel. SELET FUNTION see fig # Figure Output Relay IP Switches Setting a IP switch to the left or right makes the corresponding output relay act as a normally closed or normally open contact under the following condition: Power is supplied to the unit and no liquid covers the corresponding sensor.. Probe Inputs This section is blue in colour on the rear panel. see fig # Figure Probe Inputs MultiTrode probe would be the normal method of level detection. onnection of ball floats is also accomplished via these terminals, although this is not recommended for reliable level detection. PROE INPUTS. Output Relays This section is white in colour on the rear panel. see fig # OUTPUTS Figure 6 Output Relays 0 programmable contacts allow for the switching of contactors or other equipment. Each relay is rated at 0V mp resistive or mp inductive. The operation of the devices is controlled by level switch points hardwired to the appropriate output relay. This sets the levels at which the devices activate and de-activate. MTI / MTRI Manual R Page of 6

8 . nalog Output This section is white in colour on the rear panel. see fig # Figure nalog Output The analogue outputs supply -0m and 0-0V. It must be noted that these outputs are non-isolated. Various wiring configurations allow for -0m loads up to 0 W. UTION: Under no circumstances connect 0 volts to mains earth..6 Power Supply Terminals & Ratings Label This section is red in colour on the rear panel. 0V 0/60Hz Figure 8 Power Supply Terminals ratings label is located above the supply terminals and power is supplied through these terminals. ctive, Neutral and Earth are connected to their respective terminals as marked.

Output Relays PROE INPUTS ll output relays should be protected by an 8 amp (max.) fuse. There are 0 isolated relay outputs which can be selected N/O or N/ via IP switches to 0. Select outputs which coincide with the desired level on the probe where control is required. s the MTI does not latch each central point, this needs to be achieved using "hold in" contacts on the contactor, as per following example: Hi larm on at Standby on at, off at uty on at, off at 8 uty on at 6, off at 0 Figure Output Relays MTI / MTRI Manual R Page of 6

10 . nalog Output This section is white in colour on the rear panel. see fig # Figure nalog Output s can be seen by the diagram the MTI can drive into a maximum 0W if connected as shown. It should be noted that the analogue output is non-isolated and in certain circumstances will require a loop isolator..
