1. GENERAL DESCRIPTION The Digital Valve Sequence Programmer (DVSP) is an add-on or stand-alone timer/programmer available with either 2 or 4 intervals, settable in ranges of 0-99 seconds, 0-9.9 minutes, or 0-99 minutes.
2. IMPLEMENTATION Before removing the top cover of the DVSP, make certain that the power cord is unplugged. Remove the two screws on the upper rear panel which secure the top cover. Look at Figure 1 to locate the two barrier terminal strips located near the center of the large printed circuit board. The terminals are grouped beside letters denoting relays A, B, C, and D, and are marked C for Common, NO for Normally Open, and NC for Normally Closed.
The table below indicates which group of terminals applies to each interval for the various DVSP models. In the drawings which illustrate the different wiring options, the terminal groupings are chosen purely for convenience: there is no intent in these drawings to convey any information about specific intervals. DVSP-2 Interval 1 Relay A DVSP-4 Interval 2 Interval 1 Relay C Relay A Interval 2 Relay B Interval 3 Relay C Interval 4 Relay D 2.1 Solenoid Valves 2.
2.13 Valco MSVA The MSVA is used with a two position air actuator, which requires one interval to switch to the inject position and another to switch to the load position. The steps described below are illustrated in Figure 3. 1. Supply the proper voltage (110 VAC in this example) by connecting the HOT terminal to C of the one of the groups of terminals to be used, and jumping it to C of the other. 2. Connect one wire of each solenoid to the NEUT terminal. 3.
2.2 Valco Electric Actuators Multiposition actuators require only one event to step the valve/actuator to its next position. However, the two position actuator requires two intervals: one to switch the two position valve to its inject position and another to switch it to its load position. 2.21 Multiposition The steps below are illustrated in Figure 5. GREY WIRE WHITE WIRE 1. Locate the two pairs of adjacent grey and white wires in the interface cable supplied with the actuator.
2.3 Valco Digital Valve Interface (DVI) Two intervals are required with the DVI: one to signal it to move the valve to the inject position, and one to signal it to return to the load position. The steps described below are illustrated in Figure 7. DIGITAL VALVE INTERFACE 1. Connect the air actuator to the DVI as described in the DVI literature. 2. Locate the blue, black, and red wires in the interface cable supplied with the DVI. 3.
3. SWITCH AND DISPLAY FUNCTIONS 1. Power ON/OFF: Turns the DVSP on and off. 2. Interval duration switches: Each interval has two thumbwheel switches for setting the the interval duration, in increments determined by the setting of the time unit switches. 3. Time unit switches: Under each pair of interval duration switches is a three-position switch which defines the units in which the duration is set.
4. DEMONSTRATION SEQUENCE This example demonstrates use of the DVSP-4 to control the positioning of two Valco switching valves. Valve 1 (V1) is used for sample injection and Valve 2 (V2) is configured for column backflushing. Both valves are air actuated, but V1 is controlled by a Valco Digital Valve Interface (DVI) while V2 is controlled by a pair of 3-way solenoid valves (MSVA). Each valve requires two intervals of the DVSP; one for clockwise rotation and one for counterclockwise.
