MTIC –Indicator Controller
Four Actuation Delays:
Used to average out wave action and for other control functions.
Method of Operation:
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.

1 Introduction
WARNING:
Do not use this unit in environments that may contain flammable/explosive or
chemically aggressive gases or powders.
The MTIC is a conductive liquid level indicator and controller which continuously monitor liquid level in
order to control the operation of up to 10 appliances. It will work in the following modes:
Fill (Charge) mode: Filling a tank
Empty (Discharge) 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 4-20mA and 0-10V stepped analogue outputs for use with variable speed drives, chart
recorders etc.
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.

The MTIC has 11 LED’s. The bar graph on the left-
hand 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.

2 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.

FUNCTION
see fig #1
Figure 4 –Output Relay DIP Switches
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.
2.3 Probe Inputs
This section is blue in colour on the rear panel.
PROBE
INPUTS
see fig #3
Figure 5 –Probe Inputs
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.
2.4 Output Relays
This section is white in colour on the rear panel.
OUTPUTS
see fig #1
Figure 6 –Output Relays
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.
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.

Figure 7 –Analog Output
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 W.
CAUTION:
Under no circumstances connect 0 volts to mains earth.

Before attempting to install the MTIC 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.

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.
NOTE:
Over-tightening will deform the clamps.

5 Electrical Connections
General precautions
Electrical Hazard:
A certified electrician must supervise all electrical work. Comply with all local
codes and regulations.
Before starting work on the unit, make sure that the unit is isolated from the power
supply and cannot be energized.
Make sure that all unused conductors are insulated.
There is a risk of electrical shock or explosion if the electrical connections are not
correctly carried out or if there is fault or damage on the product.
Requirements
These general requirements apply for electrical installation:
The mains voltage and frequency must agree with the specifications for the product.
Circuit breakers must be installed between the main voltage line and this unit.
All fuses and circuit breakers must have the proper rating, and comply with local
regulations.
The cables must be in accordance with the local rules and regulations.
Cables
These are the requirements to follow when you install cables:
The cables must be in good condition, not have any sharp bends, and not be pinched.
The sheathing must not be damaged and must not have indentations or be embossed
(with markings, etc.) at the cable entry.
The minimum bending radius must not be below the accepted value.
Earthing (Grounding)
Electrical Hazard:
•You must earth (ground) all electrical equipment. This applies to the pump
equipment, the driver, and any monitoring equipment. Test the earth (ground) lead
to verify that it is connected correctly.
•If the power cable is jerked loose by mistake, the earth (ground) conductor should
be the last conductor to come loose from its terminal. Make sure that the earth
(ground) conductor is longer than the phase conductors. This applies to both ends
of the power cable.
5.1 Probe Inputs
This section is blue in colour on the rear panel.
Connect the cables from the MultiTrode probe to the corresponding input terminals.

5.2 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
Figure 12 –Output Relays
5.3 Analog Output
This section is white in colour on the rear panel.
see fig #1
Figure 13 –Analog Output
As can be seen by the diagram the MTIC can drive into a
maximum 940W if connected as shown.
It should be noted that the analogue output is non-isolated and
in certain circumstances will require a loop isolator.
5.4 Power Connection
This section is red in colour on the rear panel.

Figure 14 –Power Connections
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
