Check Out and Power Up Operational Checkout Making Connections to the Terminal Board Connect the wires from the option as follows (wire size 14 to 28 AWG, 2.5 mm 2 to .08 mm 2 ): 1. If the wires have not been stripped, strip approximately 1/4 in (6.35 mm) of the insulation at the end of wires. 2. Locate the correct terminal block on the terminal board (see Figure 21 on page 34). 3. Push back the lever at the top connector until you see the opening for wire insertion. (The connectors are spring activated and may require a lot of pressure to move the lever.) 4. Insert the wire into the opening and release the lever. Operational Checkout The operational checkout of the SVI II AP consists of: Connecting the SVI II AP to a current source Powering up the SVI II AP Checking the pushbutton locks Connecting to the Current Source Connect to a DC mA current source then check and configure with the local display and pushbuttons, if so equipped. The following section describes configuration and calibration with the optional local display and pushbuttons. If the SVI II AP is not equipped with local display use ValVue 2.4 Lite and a PC with a HART modem or a HART Handheld Communicator. Note: When an SVI II AP is turned on it is advisable to apply the air supply before applying the electrical input signal. Powering Up the SVI II AP This process can cause the valve to move. Before proceeding be sure the valve is isolated from the process. Keep hands clear from moving parts. Note: When an SVI II AP is turned on it is advisable to apply the air supply before applying the electrical input signal. Use of a low impedance voltage source will damage the SVI II AP. The SVI II AP input must be a current controlled source. The SVI II AP will not function normally if connected directly to a voltage source. However, direct connection to a current source of up to 30 V will not the damage the SVI II AP. A proper current source explicitly enables adjustment of the current in mA, not Volts. 35
Masoneilan Dresser SVI II AP Instruction Manual To power up the SVI II AP: 1. Loosen the four (4) cover screws and remove the cover of the SVI II AP. 2. Connect the +⁄- terminals from the SVI II AP to the current source. Connect + to + and - to -. See Figure 21 on page 34. 3. Reinstall the cover and display. 4. Adjust current to 12 mA. Upon initial power up of a newly installed SVI II AP, the positioner will start up in NORMAL mode and will be operational in the default factory configuration. The positioner will cycle through the NORMAL cycle menu and LCD will display the following values: PRES: (Pressure - unit of measurement and value) SIGNAL POS (Position) 5. The LCD may also display and exclamation point (!) in the top left corner of the display window. "!" indicates that there is further instrument status available. 6. Proceed to Calibration and Configuration. Note: If the SVI II AP is specified without local pushbuttons and display, local operation is not available. Configure and calibrate with ValVue 2.4 or a Hand Held HART Communicator. 36
