 Installation, initial start-up and maintenance may only be performed by trained personnel!
 The device may only be connected to power which complies 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 these operating instructions!

Functions Description:

The MAXIMAT TC4 is a signalling device for up to 4 MAXIMAT C… series overfill inhibitors / leakage sensors with
optical and acoustic indication in accordance with approval guidelines for overfill inhibitors (ZG-ÜS). If an alarm
signal is generated by one of the overfill inhibitors or leakage sensors, this can be indicated optically and/or
acoustically by the MAXIMAT TC4.

Technical Data:

Supply power: 230V AC, 50 to 60Hz, alternatively 24V DC ± 20%
Power consumption: Approx. 6VA / approx. 6W
Ambient temperature: -20 to +60°C
Protection per EN 60 529: IP65
Inputs: 4 each overfill/leakage sensor

1 external reset contact
Outputs: 4 floating changeover contacts, assigned to the individual sensors

1 floating changeover contact for group alarms
1 floating changeover contact for the external buzzer

* Note: The function test does not replace the operating test specified in ZG-ÜS, section 6.2, which must be conducted on a regular basis at

least once a year.

Contact rating, output relays: 250V AC / 115V DC
500VA / 3A

Terminals: Max. wire cross-section of 2.5 sq. mm

Note: The alarm output relays (channels 1 to 4) and the group alarm relay are pulled in (closed-circuit current) as long as no alarm is

pending. These relays are released in the event of an overfill /leakage alarm or mains power failure.
In all of the following wiring diagrams, the relays are shown in the de-energised state in accordance with the standards (mains power =
OFF)!
The relay for the external buzzer is pulled in when an alarm occurs, and is released after resetting.

Installation and Initial Start-Up:

 Mount the signalling device to the wall.

 Properly connect the signalling device to supply power (230V AC or 24V DC in accordance with the rating plate).

 Connect the sensors in accordance with the wiring diagram.

 Switch supply power on.

 The signalling device conducts a self-test (all LEDs and the piezo signal generator are tested).

 Interconnected sensors are tested: LEDs light up yellow for sensors with test connection.

 Test passed = continuously lit green LED

 Defective sensors = blinking yellow LED

 LEDs for unused channels do not light up at all.

 The following data are entered to a status list by the electronics for later use when the device is switched on for

the first time:

 Sensor connected to input: yes/no -> a single acoustic signal is generated during testing
 Respective sensor equipped with test connection: yes/no -> two acoustic signals are generated during testing

(default setting: no interconnected sensors)

 Each time the system test is conducted it can thus be determined whether or not the respective sensors function

correctly.

 If a new sensor is connected, it’s added to the status list the next time the device is switched on.

 If a sensor is disconnected, it’s removed from the status list and the respective LED is deactivated: press and

hold the reset button for at least 5 seconds. If a sensor is disconnected and not removed from the status list, it’s
indicated as defective (blinking yellow LED).

 Attention:

All sensors must be tested for correct functioning in accordance with regulations set forth in section 8
of the general technical approval during initial start-up and at least once a year thereafter!

Troubleshooting:

None of the LEDs light up and all relays are released, although supply power has been switched on:

 Miniature fuse is blown (on the lower PCB).

 Short-circuit in one or more sensor cables (between 0 and 24V);

electronic short-circuit protection has shut the device down,
rapid ticking can be heard from within the housing (only with 230V AC devices!).

Electrical Connection (floating NC contact):

Floating NC contacts * such as float actuated switches or the BSM501 bistable switch can also be connected to the
MAXIMAT TC4 signalling device.
They’re connected in accordance with the diagram shown below, and a1kΩ resistor must also be connected in
accordance with the table.

* NC contact: normal operation = contact closed, alarm = contact open

Test:
However, these contacts cannot be tested by means of the system test.
