1. Vex is the external power supply voltage Vis the voltage across the R resistor An external resistor and a voltmeter are required to calculate the internal resistor Rx value Note The user should know the R value to do this operation A 4 7KOhm 1 2W is recommended SAMPLE if you are using a 12V power supply Vex and using a 4 7KOhm as external resistor R then the voltage across R should be 6V using the equation 1 the Rx value is 4 7KOhm User s Manual Page 13 Connecting PNP sensors PNP Open collector Sensor Normally open PNP Open collector Sensor Normally closed 12 or 24V DC External Power Supply R External resistor R External resistor required required aer 5V U15 OU SV L1 13 a SVU 11 25V L 10 Board Ground Fig 7 wiring diagram to connect PNP proximity sensors Connecting PNP proximity sensor with the C10S R Value 12V R Value 24V Aprox 10KO Aprox 25KO User s Manual Page 14 Other connections Other connections can be implemented by setting the inputs to pull up resistor This example shows how to do an Auto Tool Zero by setting the inputs with pull up resistor gre IGI i Board Ground Fig 8 wiring diagram to do an Auto Tool Zero Other wiring diagrams samples are shown in the next links http cnc4pc com Tech Docs E STOP N EN Wiring pdf http cnc4pc com Tech Docs E STOP N SCHP pdf http cnc4pc com2.

Tech_ Docs C10R8 WD2 pdf User s Manual Page 15 9 FREQUENTY ASKED QUESTIONS Q The power LED on the board can light even if the board is not connected to power Is this normal A Yes the board can steal enough power from the parallel port to light the LED not for reliable operation An external regulated 5vdc that can supply at least 500mA should be used If you are worried about false signals triggering out you should use the EN terminal to disable the outputs Q have power the board and connect it to the drivers but the signals do not get to the drivers A Three conditions must be met to enable the outputs and allow signals to get through The board needs to be connected to a PC using a parallel cable that uses pins 1 25 as there is a watchdog on pins 18 and 19 that disables the outputs if the board is not connected to a PC There are some parallel cables out there that use only pins 1 17 use a multimeter to verify continuity between these pins You should have 5vdc on the EN terminal This is for external hardware disable on the board You can use a jumper between the 5vdc in the power terminal and the EN terminal n the case of boards with built in Safety Charge Pump the SCHP must be configured and active or you can disable the SCHP in the board by moving the jumper to the disable position User s Manual Page 16 10 DIMENSIONS 9 All dimensions are in Millimeters DISCLAIMER Use caution CNC m

5. Is important to understand the selection jumper functions and to know the input and output features of the devices to be connected to this board to reach a good couple Step 2 Ensure that all external power sources are set to OFF Step 3 Connect the power supply to the Power Inputs Connectors Step 4 Connect the parallel cable coming from the PC to the Female DB25 Connector Note If this board is not connected to the PC the outputs will be deactivated Step 5 Connect to the board the components of the system Step 6 Turn on the external supplies and check that the power led indicator lights Step 7 Apply 5V to the enable pin to activate the outputs A WARNING This card must have the power supplied while it is connected to the PC If power is removed to the card while it is connected to the PC noise can be introduced to the output lines This can create a dangerous situation as relays or other devices that might be connected to this card could get activated User s Manual Page 5 PIN ENABLE The card must be provided with a 5VDC signal to enable operation This feature has been added to externally control the status of the outputs An external switch or a Safety Charge Pump can be added to provide the enabling signal When the enable signal is not present output signals sent high impedance state If this function is not required an jumper can be placed between 5vdc and the EN terminal It has an internal 4 7kOhm pull down resistor
