Description of the module The Z-4-Fold Level Shifter PR0095 gives out the signal of an incremental encoder potential-free to 4 outputs. At this the input signal to the evaluation electronic and to the 4 outputs is separated. Due to an input level in the range of 4 to 24V DC it is possible to use 5V and 24V encoders. All 4 outputs are also potential-free among each other and provided by separately supplied voltage in the range of 4V to 6V. A voltage converter internally produces a 5V supply voltage for 5V incremental encoder (max. 0,9A). If the internal 5 volt supply or the feed-in of the module for supply of the incremental encoder is used there is no electrical insulation to the evaluation electronic. A micro controller assumes the separation, interlocking of jitter, recognition of direction as well as the generation of the output signals within the module. Additionally a plausibility check of the input signals is carried out. 1.1. Purpose of use The module transforms the encoder signals, which are inducted by a commercial encoder. These signals can reach a level from 5 up to 24V DC. A potential free transformation to an output level of app. 5V (depending on the supply voltage of the output and on the load) with a RS 422 trait takes place. Additionally, pulse frequency of the output levels can be given in partition ratios of 1/2/4/8/16/32/64/128 and 256, whereas the counting direction can be negated. This requires only turning a DIP-switch. Partition ratios refer only to the encoder’s counting signals (K1 und K2), the zero encoder signal is given undivided. The module’s input frequency is max. 100 kHz. The module is connected via lockable header strips and is destined for top hat rail mounting (35mm). The frequency division is inactive, the counting direction reversal is switched of and the partition ratio is set to “1” on delivery. FANUC Robotics Europe S.A.

Displays The module is equipped with 4 LED´s for display and control functions. Following the respective functions: LED4 – red (top) – unit ready-to-operate LED1 – red (second from the top) – encoder signal Port 1 LED2 – red (third from the top) – encoder signal Port 2 LED3 – red (fourth from the top) – encoder signal port 0 FANUC Robotics Europe S.A.

Settings The partition ratio of the encoder signals and the counting direction can be set by means of the DIP-switches, which are accessible from outside of the housing. The partition is only active if the DIP-switch 4 is set to OFF, in that case the partition is defined by the combination of DIP-switch 1 to 3. DIP switch 5 negates the counting direction independent from the setting of the other switches. Advice: The states of the Dip-switches are only read in at switch-on of the power supply, thus changes do not have any effect until the module is restarted.

Trouble shooting As an optical indicator the module features 4 LED’s which allow for error detections on malfunctions. Note: During operation the brightness of LED 1-3 depends on the incoming frequency of encoder signals (flickering). Especially LED 3 might possibly not glow properly if the incoming frequency is quite low. Kind of error Signal on the module Trouble shooting Signal receiver does not receive any signals LED 4 does not glow Supply voltage is not available or reverse-poled, check wiring and power supply Signal receiver receives signals but reports encoder error LED 3 glows very bright Encoder zero-impuls is reversepoled, change wiring to correct polarity Signal receiver does not receive any signals LED 1 or 2 glow very bright, independently from the encoder incoming frequency Port 1 or 2 is not assigned with encoder counting signals but e.g. with supply voltage; make up correct wiring Signal receiver does not receive any signal LED 1- 4 glow Power supply for the respective output is not available; check wiring of the output on the module as well as the power supply Table 6: Possible errors/causes and trouble shooting Please check all mentioned sources of error first before returning the tool!
