1. Make sure the shop air provided to the servo valve is clean and dry and that the input air pressure is
regulated such that the output pressure is no more than 75 psi. For more reliable operation, install an in-
line air filter to keep out dirt, oil and moisture. Attach air tubing to the input port of the valve, making
sure there are no air leaks. Attach output tubing to brake or clutch making sure tubing does not contact
any moving parts on the machine.
2. Select desired output, 0 to 10V or 4 to 20mA by positioning the jumper on JP1of the driver card. The
jumper should cover pins 1 and 2 for 0 to 10V output, or pins 2 and 3 for 4 to 20mA output.

3. If +24Vac is required for servo, position jumpers on pins 1 and 2 on JP2 and JP3. Default is +15Vdc.
