Leybold Turbotronik NT 12 CE Turbo Pump Controller For TMP 50 Turbo Pump, 180-260 V AC, 50/60 Hz, 85904

Overview:

The TurboTronik NT 10, NT 12 and NT 13 frequency converters are used to drive TURBOVAC 50 and 50 D.

The electronic frequency converters convert the single-phase supply voltage into a three-phase AC voltage to control the TURBOVAC induction motor.

The frequency converters operate according to a specific cycle: The motor is driven for approximately 1 second and the monitoring measurements are executed in the following 0.1 seconds.

The following operating statuses are displayed using LEDs:

• supply voltage present
• run-up
• standard and
• fault Optionally

Various signals are available via 2 relay outputs.

After the start, the pump continuously accelerates with the maximum current. This is identified by the yellow LED "ACCEL" (acceleration) which is lit. The green "NORMAL" LED is lit and the "ACCEL" LED goes dark when approximately 90% of the rated speed is reached.

The speed is continuously monitored and controlled. When the speed cannot be maintained, even at the maximum current, as a result of external influences, e.g. excessive gas feed, the speed decreases and the pump continues to operate.

When a rotational frequency of approximately 500 Hz is fallen below, the "ACCEL" LED lights-up on the frequency converter. The TURBOTRONIK now attempts to accelerate the pump up to its reference frequency.

The frequency converter outputs are no-load- and short-circuit proof.

The electronic TURBOTRONIK frequency converters can be connected to external open-loop control- and monitoring devices with electrical isolation.

The cable connections between TURBOTRONIK - TURBOVAC can be a maximum of 100 m.
