Caution
Trained personnel may only perform installation, initial start-up and maintenance.
All applicable European and national regulations regarding installation of electrical e uipment must be adhered to.
- The device may only be connected to supply power complying with the specifications included in the technical data and on the serial plate.
- The device must be disconnected from all sources of power during installation and maintenance work.
- The device may only be operated under the conditions specified in the operating instructions.
The compact overfill probe MAXITOP is used as an overfilling monitoring device for permanently installed containers used for the
storage of non-flammable, water endangering liquids.
The MAXIMAT has four different possible transmissions:
• Low voltage output (max. 50 V ac/dc, max. 0.5 A, max. 10 VA)
• Relay output in use with a CST device
• Direct connection to a PLC
• Direct connection to an alarming unit TC4

-"1+In accordance with low-voltage directive (2006/95/CE), EMC directive (89/336/EWG).
Main power supply: 15 ... 26 V DC (when a fuse 250 mA is installed)
Power consumption: approx. 3 W
Ambient temperature: -20 to +60° C
Operating pressure: atmospheric (0.8 to 1.1 bar)
Stem: PEHD
Process connection: 2" G, PVC, sliding – adjustable immersion depth
Terminal housing: PBT, fibre glass reinforced, IP 65 acc. E 60 529
Terminals: Screw connectors, IP 20; max. wire cross-section 2.5 mm_
Input for an external push in order to run a test sequence
Signalling display: 1 LED (green) inside the terminal housing; lighting = perfect conditions; Off = or alarm status or Error status
!: 2 wires cable symbol
The external test push button is useful for a diagnostic of the system. It is not necessary for the proper detection mode.

The measuring sensor works in accordance with the capacitive
proximity switch principle. In this application the non-conductive
medium –air- changes to a conductive medium –stored chemical-
when an overfilling or a leakage occurs.

The measuring sensors are suitable to liquids for which reactive
impedance is less than +)-$-, or with a coupling capacitance
to earth is greater than 0. Stored liquids may not tend to preci-
pitate insulating or conductive sediments.

The frequency for testing the complete system should be at least
once a year, or more often, and in any case according to the rules
of the Country where is the installation.
Observe the instructions from the “General Building Supervisory Approval” (concerns
the probes that re uire a specific approval).

Test method
Cable / wire
for earthing the liquid
.Fill a bucket (plastic or metal) with original liquid
or water (at least 5 litres).
.Earth the liquid in the bucket with a cable/wire.
or
.Grasp the bucket with your hand from the outside.
or
.Immerse a finger into the liquid.
.At the same time, immerse and remove the measuring
probe several times.
.Examine the switching status of the measuring circuit
(refer to the respective operating instructions to this end).
