Although the laser output is low looking directly into the laser beam must be avoided. Due to the visible light beam eye protection is ensured by the natural blink reflex. The housing of the optical sensors optoNCDT1800/1801 may only be opened by the manufacturer. For repair and service purposes the sensors must always be sent to the manufacturer. -

Page 18: Averaging Number N
1) When the number of averaging is changed, an error will continue to be sent until the required number of measurement values for the selected averaging count have been reached (logged). For the optoNCDT1800/1801 and a number of averaging of 128, the maximum time required is 26 ms (128 x 0.2 ms = 25.6 ms) -
Page 19: Averaging Type
When the controller is switched on again the next time, the last selected averaging method will be indicated during booting by the momentary illumination of the LEDs “AVG1” and “AVG2”: Tab. 6.3: LEDs display the averaging type during booting optoNCDT1800, 1801... -

However, it requires extremely long transient recovery times for steps in measurement values. The recursive average shows low-pass behaviour. The output frequency stays constant at 5 kHz / 2.5 kHz for the measuring range of 500 mm. Standard values for N: 1, 4, 32, 128 (window width). optoNCDT1800, 1801... -

MICRO-EPSILON The data word consists of two consecutive bytes which are transmitted in series without a identity bit. Use the IF2004 interface card (available from MICRO-EPSILON) for communication with a PC. Interface card and controller are connected with the PC1800-3/10/RS485 interface cable (available from MICRO-EPSILON). The interface card combines the both bytes from the data word and storages it as a 16 bit value in the FIFO. -
