Connection 2.9 Modifying the Relay FAILURE (Option) 2.10 Installing the TURBOTRONIK On delivery the relay FAILURE is a resting contact (normally closed). It can be changed to an operating contact (normally open). Install the TURBOTRONIK. Warning Before you open the TURBOTRONIK please first ensure that the TURBOVAC has been braked to a complete standstill, and that the mains power cord is disconnected.

Operation 3 Operation 3.1 Start-up Insert the power plug. Switch on the POWER switch. Having switched on the power switch the TURBOVAC’s stabilizer is activated and the rotor lifts up. Afterwards all LEDs light up for approx. 2 s for a functional check. The green LED „POWER“ remains on. On the TURBOTRONIK NT 340 MA and 341 MA with temperature control the temperature control is switched on. It is not necessary to check or to recalibrate the rotor position control system.
Operation 3.4 Operation During normal operation the TURBOVAC runs with target speed. The LED NORMAL lights and the LED chain shows - starting at the bottom and moving upwards the current consumed. In case of increased load (e.g. increased pressure due to a leak) the speed is compensated via an additional current consumption. Thus, the number of the lighting LEDs is a measure of the pressure rise. A further pressure rise beyond the point of the max.
Operation 3.8 Shutdown of the TURBOTRONIK Press the STOP key, and wait until the pump comes to a standstill. The LEDs in the keys START, STOP and NORMAL are extinguished. Switch the POWER switch to the “0” position. The temperature control at the TURBOTRONIK NT 340 MA and NT 341 MA with temperature control is switched off. If the red LED DON’T DISCONNECT has gone off the connection lines to the TURBOVAC can be disconnected in case of necessity.
Troubleshooting 4 Troubleshooting When a malfunction occurs, the TURBOVAC is braked and the failure is indicated; see following table. The red LED FAILURE lights permanently and one green LED within the chain flashes. When the pump is at a complete standstill, and after you have eliminated the cause of the failure, you can reset the malfunction signal with the STOP command (key or remote control).
