1 INSTALLATION & OPERATION MANUAL FOR MultiTrode Indicator Controller (MTIC) & MultiTrode Remote Indicator Controller (MTRIC) MTIC - Indicator Controller MTRIC - Remote Indicator Controller Version 598

2 MTIC INDICATOR CONTROLLER and MTRIC REMOTE INDICATOR CONTROLLER MTIC - Indicator Controller MTRIC - Remote Indicator Controller MTIC - Indicator Controller Four Actuation Delays: Method of Operation: Used to average out wave action and for other control functions. The MultiTrode MTIC 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 0-10V DC or 4-20mA current loop. Until the advent of this MultiTrode system, these facilities had not been economically practical for hydraulic services in high-rise buildings. MTRIC - Remote Indicator Controller Continuous Level Indication: Using a high-intensity, 10-segment LED bar-graph. 10 Relay Outputs: Enabling control of multiple pumps, alarms and other devices. Level Selection: Simple level selection and adjustment without entering pit or tank. Variable Speed Drives: Can be controlled via 4-20mA or 0-10V DC output. Remote Indication and Control: 4-20mA or 0-10V DC outputs will operate MultiTrode Remote Indicator Controller up to a distance of several miles. Four Sensitivities: Enable the system to operate effectively in a wide range of conductive liquids * This product is covered by an exchange unit program (see back page for details). 2

3 INTRODUCTION The MTIC is a conductive liquid level indicator and controller which continuously monitors liquid level in order to control the operation of up to 10 appliances. It will work in the following modes:- Charge mode: Discharge mode: Filling a tank 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 4-20mA and 0-10V stepped analogue outputs for use with variable speed drives, chart recorders etc. An MTRIC can also be connected to the 4-20mA output of the MTIC to remotely indicate level, and control appliances at a distance of up to several kilometres from the MTIC.11 front-panel LED indicator lamps give a readout of level and power supply status. The front panel allows for placement of labels to indicate at which point devices will activate. A 4-way DIP switch on the rear panel provides for the setting of four sensitivities and four time delays. In addition, a 10- way DIP switch allows for the setting of the relays as Normally Open or Normally Closed. Front Panel The MTIC has 11 LEDs. The bar-graph on the lefthand side indicates level, whilst the green LED 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 10 labels can be placed here. Rear Panel The MTIC rear panel (see drawing ) contains the terminals, as well as function DIP switches, used to preset the unit's basic operations. This section describes the function of each terminal and DIP switch. 3

4 FUNCTION DIP SWITCHES An important step in the commissioning of the controller is to preset the positions of the rear panel DIP switches. This will set up the basic operation of the unit to match the installation. The following tables show the switch functions. Timer and sensitivity DIP switches This section is black in colour. The MTIC should be switched off prior to altering the DIP switch settings. SW Function Position Description A B A B A B A B C D C D C D C D Timer Timer Timer Timer Extra low sensitivity 1KΩ Normal low sensitivity 4KΩ Normal sensitivity 20KΩ High sensitivity 80KΩ Instantaneous actuation when level reaches sensor. Time delay on actuation approx. 5 seconds. Time delay on actuation approx. 10 seconds. Time delay on actuation approx. 15 seconds. For concentrates such as acids, minerals, alkalis leaving residue. Acids, alkalis, diluted brine, sea water. Sullage, sewage effluent, town water. Effluent and processes with oil contaminants, purified water. Note: Conductance may vary from liquid type as described above. Adjust sensitivity as required. 4

5 Output Relay DIP switches (Dwg #1) This section is black in colour.] Setting a DIP 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, labelled Probe Inputs (Dwg #2). A MultiTrode probe would be the normal method of level detection. Connection of ball floats is also accomplished via these terminals, although this is not recommended for reliable level detection. Output Relays This section is white in colour, and labelled Outputs (Dwg #3) 10 programmable contacts allow for the switching of contactors or other equipment. Each relay is rated at 240VAC 5 Amp resistive or 2 Amp inductive. CONTROL SWITCHING LEVELS 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. Analogue Output Power Supply Terminals And Ratings Label This section is white in colour (Dwg #4) The analogue outputs supply 4-20mA and 0-10V. It must be noted that these outputs are non-isolated. Various wiring configurations allow for 4-20mA loads up to 940 Ω. *Under no circumstances connect 0 volts to mains earth. This section is red in colour. A ratings label is located above the supply terminals and power is supplied through these terminals. Active, Neutral and Earth are connected to their respective terminals as marked 5

6 INSTALLATION AND POWER-UP Before attempting to install the MTIC/MTRIC read this section thoroughly. Check the power rating label above the power input terminals (see drawing below). Make sure that the power supply configuration is compatible with the installation being carried out. MOUNTING Mount the MTIC into a 91.0mmx 91.0mm hole (see drawing). The clamp brackets will allow installation into panels up to 8mm (absolute max.) thickness. Slide the controller in from the front of the panel. Insert the two clamp brackets into the double slots in the top and bottom of the case (see drawing). Tighten the screws sufficiently to hold unit. (Over-tightening will deform the clamps.) 6

7 ELECTRICAL CONNECTIONS Probe Inputs Connect the cables from the MultiTrode probe to the corresponding input terminals. Output Relays All output relays should be protected by an 8 amp (max.) fuse. There are 10 isolated relay outputs which can be selected N/O or N/C via DIP switches 1 to 10. Select outputs which coincide with the desired level on the probe where control is required. As the MTIC does not latch each central point, this needs to be achieved using "hold in" contacts on the contactor, as per following example:- Hi Alarm on at 1 Standby on at 2, off at 7 Duty 2 on at 4, off at 8 Duty 1 on at 6, off at 10 Analogue Output As can be seen by the diagram the MTIC can drive into a max. 940 Ω if connected as shown. It should be noted that the analogue output is nonisolated and in certain circumstances will require a loop isolator. Power Connection Prior to connecting the power to the controller, the following checks should be performed:- 1.Check the controller voltage rating to ensure compatibility. 2.Check that the function DIP switches have been set for the correct defaults. Connect as follows:- A = Active N = Neutral E = Earth 7
