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. The DVSP is most commonly used for
remote operation of electrical devices such as solenoid valves, Valco two position
or multiposition electric actuators, and the Valco Digital Valve Interface (DVI), which
converts contact closures into pneumatic pulses for switching Valco two position air
actuators.
The DVSP has two operational modes: in the AUTO mode, the DVSP will return to
the first interval and begin another sequence after the last interval is completed,
and in the SINGLE CYCLE mode it stops after one sequence. During a cycle or
sequence, simple controls allow the user to stop the cycle, reset it to Interval 1,
switch to the AUTO mode, or advance to the next interval. The DVSP can also be
wired for remote operation by contact closure from a data system or other control
device.
Each interval has one DPDT (double pole, double throw) relay, which provides two
sets of contacts with no connection from one side to the other. This means that a
single interval can be used to perform two separate functions requiring differing
voltage requirements. For example, one side of relay A (Interval 1) can be used to
switch an electric actuator (contact closure) while the other side is connected to
110 VAC and switches a 110 VAC solenoid valve at the same time as the electric
actuator. In addition, Relay E (functional only in the AUTO mode) supplies a two
second contact. When solenoid valves are wired in series with this relay the result
is "pulsed operation" of the air actuator, which avoids the potential valve and actuator problems associated with continuously-applied air pressure.
Both 12 VDC and 110 VAC power supplies are included within the DVSP, but the
relays may be supplied from any external power source. For example, 24 VDC
solenoid valves can be switched by the DVSP relays if the 24 volts is supplied to
the relays from an external 24 VDC power supply.

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. For convenience, the power line (fused and switched) is
connected to two of the terminals on the DVSP mother board, labelled HOT and
NEUT. HOT is the high side of the line and NEUT is the low side.

Figure 1: View of DVSP with cover removed
For operation of devices requiring line voltage (1 amp max), one side of the device
is connected directly to the NEUT terminal and the HOT is switched by the output
relays. For devices which operate on 12 VDC (300 mA max), voltage can be
supplied to any of the relays with a simple jumper connection between the terminal
marked 12 and the Common terminal of the target relay. (Figure 2) Any external
power source can be connected to a Common in the same manner, with a hole
provided in the rear panel to allow a passage for all the external wiring.
The DVSP output relays are double pole, double throw (DPDT), meaning that they
have two separate sets of contacts with no connection from one set to the other.
One contact of each set is the common (C), which is connected to the normally
closed (NC) contact when the DVSP is not in the interval corresponding to that
relay. As the DVSP enters each interval, the corresponding relay switches and
connects the common (C) terminal to the normally open (NO) terminal, sending
the current to the external device.

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.

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. Connect the other wire of each solenoid to the NOs which
correspond to the Cs of Step 1, according to the desired
switching sequence.

Pulsed Operation of Solenoids
The first three procedures demonstrate the simplest uses of the DVSP. This
example will illustrate the use of the pulsed relay in conjunction with two devices
on the same DPDT relay. The steps described below are illustrated in Figure 4.
1. Connect the two wires of the 12 VDC
solenoid as described in Section 2.12.
12 VDC SOLENOID
110 VAC SOLENOID
2. Connect one wire of the 110 VAC solenoid to NEUT as described in Section
2.11, but connect the other wire to the
second NO terminal of the same relay
to which the 12 VDC solenoid is connected.
3. Supply 12 VDC by connecting the +12
terminal to one of the NO terminals on
the pulsed relay (Figure 1) and
connecting that NO’s related Common
to the Common of the NO which has
the 12 VDC solenoid connected to it.
4. Likewise, supply 110 VAC by connecting
the HOT terminal to the remaining NO
terminal on the pulsed relay and
connecting that NO’s related Common
to the Common of the NO which has
the 110 VAC solenoid connected to it.

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. The relevant pair for this application is the one near the center of the ribbon
cable.
2. Connect the grey (STEP) wire to the NO
terminal of the appropriate relay.
Figure 5:
Valco multiposition electric actuator
3. Connect the white (GRND) wire to C or the
same relay.
2.22
BLACK WIRE
Two position
The steps below are illustrated in Figure 6.
1. Locate the black, red, and green wires in the
remote switching cable extending from the
cover of the actuator.
2. Connect the black (INJECT) wire to the NO
terminal of the appropriate relay for the desired interval.
GREEN WIRE
RED WIRE
Figure 6:
Valco two position electric actuator
3. Connect the red (LOAD) wire to the NO
terminal of the relay corresponding to the
interval where sample is to be loaded.
4. Connect the green (GRND) wire to the
Common of one of the relays and use a
jumper to connect it to the Common of the
other relay.
5
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. Connect the blue (INJECT) wire to the NO terminal
of the appropriate relay for the desired interval.
4. Connect the black (LOAD) wire to the NO terminal
of the relay corresponding to the interval where
sample is to be loaded.
BLUE WIRE
5. Connect the red (GRND) wire to the Common of
one of the NOs used in Steps 3 and 4, and use a
jumper to connect it to the Common of the other
NO.
In routine operation the DVSP will control the
switching of the valves, so manual control through
the DVI will not be an issue. However, it is possible
to allow the option of manually overriding the positioning of valves switched by the DVI. To do this, the
DVSP signal must be removed from the DVI remote
cable by routing the DVI common (RED) through the
pulsed relay, E. The signal from the DVSP is applied for only two seconds and then removed, permitting subsequent manual valve positioning with
the switch on the front of the DVI.

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.
With this switch to the left the unit is minutes, so the two digits of the duration switches reflect a value from 00 to 99 minutes. In the middle position
the unit is tenths of a minute, with a range of 0.0 to 9.9 minutes. (In this
setting the elapsed time display shows a decimal point.) When the switch is
to the right the thumbwheel duration switches are setting seconds, in a
range from 00 to 99.
4. ADVance button: This will advance the DVSP into the next non-zero interval. Everything functions as if the timer had reached its setting and advanced to the next interval on its own.
5. AUTO button: Pushing this button toggles the DVSP in and out of the AUTO
mode. In the AUTO mode (AUTO LED on), when a cycle is completed the
DVSP goes back to the first interval and starts another. In the SINGLE
CYCLE mode (AUTO LED off), the timer stops at the end of the last interval.
6. ReSeT button: Pressing this button sets the DVSP to the state it’s in when
first turned on: the timer is stopped and the DVSP is in the SINGLE CYCLE
mode. No interval is being addressed and no relays are energized.
7. RUN button: Pressing this button lights the RUN LED, starts the timer, and
moves the DVSP to the first interval not set to "00".
8. STOP button: This stops the timer and resets it to zero, but the DVSP
remains in the interval that was in progress and the output to the relays
stays the same. The RUN LED goes off.
9. Current interval lights: Between each time unit switch and interval number
is an LED which comes on when that interval is current.
10. Elapsed time readout: This digital display to the left of the VICI logo shows
the elapsed time in the interval which is running, indicated by which current
interval light is on. The display is in the value range selected by the three
position time unit switch for that interval. Whenever the timer is counting
minutes, the decimal light flashes at one second intervals.
3.1 Operating the DVSP by Remote Contact Closure
The DVSP can be wired so that the functions done by RUN, STOP, and AUTO
buttons can be done by remote contact closure. This involves soldering wires from
the control device to the appropriate pins on the logic board. (Figure 1) For the
RUN function, establish momentary contact between pins 18 and 35 (+12). For
the STOP function, momentarily connect pins 17 and 35. Connecting pin 22 to pin
34 (ground) will toggle the DVSP in and out of the AUTO mode.

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. (All references to directions are as seen from the actuator end of the valve.)
In the ready (rest) state, both valves are in the counterclockwise position. (Figure
8) After the process is begun by charging the sample to V1, V1 will be switched
clockwise to inject the sample. (Figure 9) After two seconds for sample injection,
V1 is returned to the counterclockwise position to load the next sample. In this
example, fifteen minutes will elapse before V2 is switched clockwise and the
contents of the column are backflushed to the detector. (Figure 10) After nineteen
minutes for desorbtion of the column contents into the detector, V2 is switched
counterclockwise for the next sample analysis. Four and a half minutes will be
allowed for equilibration before the next cycle begins.

(Interval 3)
Broken down into its component intervals, the process appears like this:
Interval 1 (2 seconds)
Relay A is energized, switching V1 to its clockwise position and injecting the
sample onto the column.
Interval 2 (15 minutes)
Relay B is energized, switching V1 back to the counterclockwise position,
ready for the next sample.
Interval 3 (19 minutes)
Relay C is energized for two seconds (through relay E), switching V2 and
backflushing the column to the detector.
Interval 4 (4.5 minutes)
Relay D is energized for two seconds (through relay E), switching V2 to the
column forward position, ready for the next run. If the DVSP is in the AUTO
mode, the next cycle will begin after 4.5 minutes.

Programming the DVSP is very simple now that the process has been broken into
steps:
1. Set the switch beside the "1" to the right, for "seconds", and set the
thumbwheel switch to 02.
2. Set the switch beside the "2" to the left, for "minutes", and set the
thumbwheel switch to 15.
3. Set the switch beside the "3" to the left, for "minutes", and set the
thumbwheel switch to 19.
4. Set the switch beside the "4" in the middle, for "tenths of minutes", and set
the thumbwheel switch to 45 (4.5 minutes).
The wiring connections for the demonstration sequence are illustrated in Figure
12. Since V1 uses the DVI (with a built-in two-second relay) it is simply wired to
DVSP relays A and B which correspond to Intervals 1 and 2. (A jumper connects
the Commons.)
Since V2 is switched by a pair of solenoid valves, it is important that the current
which activates them is supplied only as long as it takes to switch the valve, even
though the DVSP relay is energized for the entire length of the interval. To provide
this pulsed current and avoid the problems associated with continuously-applied air
pressure, the DVSP features a fifth relay (E) which is activated for two seconds at
the beginning of each interval. When the "hot" leg of each solenoid is run through
relay E, the power is applied to the solenoid only during the initial two seconds of
its interval.
