STEP BY STEP FOR SETTING UP A C76 FOR
UCCNC MARCH, 2021
The main objectives of this step-by-step instructions are:
- Power the Board and e-stop and test that the board activates/deactivates at hardware level only
with e-stop.
- Install the UCCNC license and configure the pinout and functions of UCCNC supported by
the C76 and test that UCCNC is communicating with the C76 OK.
- Enable and configure the Safety Charge Pump to make sure the C76 activates (green LED)
when UCCNC becomes active (out of reset).
1. Make sure the controller is connected to an Ethernet port on the PC and powered with LEDs
ON.

2. Connect an E-Stop button to short the E-Stop terminals, disable VFD Alarm jumper and
disable the Safety Change Pump (JUMPER=OFF). The SCHP is watchdog, which will allow
the board to activate onlywhile thecontrol software is active. This should activate the board
(green LED). IFnot, check other possible fault conditions and make surethey are not active.
3. The UCCNC license must be installed in order to establish theconnection with the hardware.
Replace the demo license that comes with the UCCNC installation with the license that you
purchased.
4. Run the UC Utilityxxx program to establish the connection, set a fixed IP on the PC’s LAN
card and whitelist the device on the network. You may need tomanually configure the LAN’s
IPv4 protocol to use a fixed IP.

7. Test the E-Stop by opening the circuit a confirming the green LED goes off. You can now
enable back on the SCHP by moving (JUMPER=ON) so it will be UCCNC what will enable
the system. You should get the green LED while the e-stop switch is closed and UCCNC is
active.
