Test Device Gel 210TX
Field of Application
This device serves to check encoders with square-wave signal-outputs with the following signal shapes:
T, TNoperating voltage - UB = 5 V DC + 5 %
current consumption - max. 35 mA
V, VN, X, XN
operating voltage - UB = 10 ... 30 V DC
current consumption - 40 ... 80 mA
Functioning:
Each signal output of the encoder is checked for its ability to deliver a valid high or low signal. This is acknowledged by either the red or the green LED. One output is loaded with approx. 2.8 k against 0 V and against UB. The low level must not be higher than 20 % of the operating voltage. High level must be at least 80 % of the operating voltage. If the signal levels are not correct or there is no output signal at all (e.g. a failure of contact), the corresponding LED is off. For the signal shape V there is no display for the inverse signals (lower row of LEDs).
Caution:
The encoder to be tested needs to be fed via the testing device GEL 210.
