DISABLING PORT POSITIONS CAUTION Always ground yourself before and while touching the jumpers to prevent static discharge A set of 8 jumper pins near the top right of the circuit board marked DISABLE PORT are to allow the installer to disable certain positions of the valve Installing a shorting plug between the two pins will disable the specified position Refer to board drawing on page 18 for jumper location The positions are marked 1 to 8 on the circuit board When advancing in manual STEP mode with the optional control station the controller will skip over the disabled position and continue to advance to the next enabled position NOTE When a position is disabled the controller will not accept a command to go to that position The controller will just respond to the command with a disable status Using remote RS 485 communication if a disabled port is selected the MEC controller will not move to that position J CONTROLLER ADDRESS CAUTION Always ground yourself before and while touching the jumpers to prevent static discharge A set of 8 jumper pins near the top left of the circuit board marked ADDRESS PORT are to allow the user to set a unique address for the MEC controller With power supply off setting a jumper across the two pins will set the controller to the specific address in decimal The user can select single or multiple jumpers the address in decimal will be the sum of all jumpers that have been set

11. ATURES When a command is sent from the host device to move the valve to a position the MEC turns on the motor and monitors the position until the valve is within a few degrees of actual position At that time the motor will be turned off to prevent its momentum from overshooting the required position If the valve is still not quite on position the microcontroller will pulse the motor to slowly move to the exact position The microcontroller will also compensate for changes in torque requirements to accurately position the valve regardless of the media or valve conditions Small pushbuttons on the circuit board allow local control for calibration maintenance purposes Jumpers on the circuit board will disable any ports on the Multiport Valve which are not being utilized LED s on the circuit board indicate operating status MULTIPORT ELECTRONIC CONTROLLER continued F OPTIONS 1 The optional digital display will indicate the valve position by port numbers 1 to 8 The corresponding port number will flash on the display when the valve plug is moving near or passing by a port whether by using local controls or remote commands Once the movement has stopped the display will flash the port number that the valve is nearest or a solid port number if the valve is exactly on position The decimal point on the LED display will flash to indicate that all functions of the MEC are operating normally 2 The optional local control station contain
