For reasons of safety the sensor test can only be performed during the first 15 seconds after switching on. The zero adjustment can be performed after a turn-on period of 15 seconds (illustration 27). The termination of the 15 seconds period is signalized by a short blinking of the LEDs of the connection housing. Illustration 27 Automatic zero adjustment (illustration 28) If the „push button“ T1 is activated for a period of 2 seconds, the output of the torque signal is automatically set to 0 Volt. The adjusting is effected irrespective of the amount of the actual torque. The termination of the adjustment is confirmed by fast blinking of the LED L1. The new zero point has been saved and the device is in the measuring mode again. • The automatic zero adjustment can only be performed if the measuring shaft is switched on for more than 15 seconds. • If necessary, the automatic zero adjustment can be performed by an external control, too. If the potential of the terminal clamp T1 is connected with GND for 2 seconds, an automatic zero adjustment is performed.

Torque Measuring Shaft Operating/Assembly instructions 4 KTR-N Sheet: Edition: 49018 EN 20 of 22 1 Assembly 4.11 Technical description Manual zero adjustment The zero point of the torque output can be adjusted manually. For this purpose both push buttons T1 and T2 are activated simultaneously for 2 seconds. The LED L1 is blinking four times. Pressing the push button T1 increases the voltage, pressing the push button T2 decreases the voltage. The modifications are accelerated if the corresponding push button is pressed permanently. Each amendment is confirmed by short blinking of the LED L2. Having performed the adjusting the new values are stored lastingly by pressing both push buttons again for 2 seconds. The LED L1 is illuminated once and signalizes the return to the measuring mode. • The manual zero adjustment can only be performed if the measuring shaft is switched on for more than 15 seconds and the signal has levelled off. Illustration 29: Manual zero adjustment Sensor test During the first 15 seconds after powering up the torque sensor can be inspected for operativeness. If the push button T2 is pressed for 2 seconds the torque voltage output will be increased by approx. 4 Volt for the period of 2 seconds. • The sensor test can only be performed during the first 15 seconds after switching on.
