CZi Sensor (with Serial Interface)
(5).3 In case of checking the output amplitude
・Please refer to the section 3 “electrial specification” in checking the output amplitude.
・Lissajous’ waveform of A /B phase signal is close to a true circle
・In checking the output amplitude without connecting SVM, please connect 5V and 0V check-pin to the power source.
NOTE
・The sensor, the preamplifier, and the detection ring are adjusted by the set. So use them by the set and do not touch the
variable resistance in a preamplifier.
・Sensor side connector part has the marking of "CN1”(black) and “CN2”(Blue)”. When connecting them to the preamplifier,
please check these marks on the connector.
(6) Connecting the preamplifier ground to the machine
The preamplifier should be connected to the grounded machine. Attach the preamplifier box to the machine with the
earth cable using the connector plate screw as shown in the example a) below, or remove the painting of the preamplifier
box in the area that the screw touches directly and fix the screw when attaching the preamplifier box to the machine as
shown in b) below.
