Screw Conveyors – Waste incineration system screw conveyor

G4BM480V12ADTL20 Tele Haase product.

G4BM480V12ADTL20 Tele Haase product.

Task:

Shutdown of the screw conveyor in the event of overload.

Solution:

The screw conveyor in a waste incineration plant is monitored for overload. If the screw becomes blocked or if pieces in the conveyor are too heavy, this is detected by means of the effective power consumed by the motor, and the conveyor is switched off.

Use/value:

  • Prevention of excessive wear on the screw conveyor
  • Low maintenance requirements thanks to detection of the load state based on power consumption, without sensors.

Supply Pumps – monitoring of supply pumps

Monitoring of supply pumps

Supply Pumps
Monitoring of supply pumps. E1PF400VSY01 Tele Haase product.

Task:

Ensuring the correct rotation direction for the supply pump in a hydropower plant.

Solution:

By monitoring the connected phases for failure and phase sequence, any error status is detected.

If the the rotating field is connected incorrectly when the pump is put into operation, the supply pump does not start.

The rapid detection of phase failure must be ensured in order to prevent the motor and thus the pump from being damaged.

Use/value:

  • Prevention of overload in the event of incorrect running direction and shutdown
  • Safe detection and shutdown in the event of phase failure

E3IF500mAAC Tele Haase
E3IF500mAAC Tele Haase

Task:
A charging unit for forklifts is to be protected against overheating. The charging current is high at the beginning of the charging process, and the charger is to be cooled with a fan.

Solution:
On the primary side, the current consumption of the charger is monitored. If the set threshold is exceeded, the output relay is tripped and switches the fan on. When the charging current falls (maintenance charge), the fan is switched off.

 Use/value:

  • Simple implementation
  • Protects the charger

Grid stability in the control cabinet

Controlling the future

Grid stability in the control cabinet

The brown-out detector from TELE can identify short-term interruptions in the electricity grid. Such line failures can lead to undefined conditions in control cabinets. Downtimes and high costs are a result.

V2UF230V10

Application

The brown-out detector from TELE reliably detects power fluctuations. It detects brown-outs / short interruptions of at least 10 ms, whereby the reaction time of the short-term interruptions is adjustable between 10 ms and 40 ms via potentiometer. Using the brown-out detector prevents undefined states from occuring in switching and control equipment.

Should there be a short interruption or a brief voltage drop, the device detects this an switches the system off (Reset). When the mains voltage returns, the unit switches back on after a delay (adjustable between 0.5 and 10 seconds).

A clever combination: TST01 meets OVP1

OVP1 the TELE auto/manual override and the new ultra compact single phase Thyristorstack TST01 are an ideal space and cost saving combination of automation components for the safe and easy control of electric heater elements, infrared lamps or small ac motors.

Using this combination of modules, you receive:

  • a fully function auto/manual override
  • a feedback circuit and indication, that the unit is in manual mode
  • an integrated potentiometer with scaling 0..100%, which equals 0..10VDC output
  • an amplified buffered output signal to drive the power stack

All these functions are combined in a 17,5mm (1TE) wide housing for DIN-rail mounting, with rugged terminals, designed and manufactured in Austria.

The new compact thyristor stack Model TST01 is available from 8A to 25A load current (approx. 1,5kW up to 5,5kW) to control electric heater elements, infrared lamps and small 1ph AC-motors. A 0…10VDC signal is to be used as a control input and of course the fully isolated. The firing mode is phase angle for universal use with resistive and inductive loads and to offer fully continuous control of the RMS load voltage. The ultra slim housing is 45mm (2TE) is made of aluminum and can be mounted on a DIN-rail. No auxiliary voltage supply is necessary, as the units receive the supply via the power terminals that save wiring and external fusing. A digital input is available to start and stop the thyristor power devices.

The combination of both modules gives you an efficient and easy to use method, connecting the thyristor power controller to a controller or control system. Commissioning, service and plant testing is easier and saves labor in changing, connecting and disconnecting wires. Switching the OVP1 to manual mode the control system gets a digital signal that the automatic status is no longer valid.
