1.4.3 Connecting the Alarm Relay
With the pressure module installed, a relay contact is provided for
controlling an external alarm. This relay is a single form-A contact.
It is activated when either the high alarm threshold is exceeded, or
the pressure drops below the low alarm threshold. The connection
is made at the two-pin connector TB5. See Figure 2 Wiring

1.5 Three Position Selection Switch Wiring
An optional mode selection switch is available with the weather-
proof enclosure. With this switch the user may select either contin-
uous cleaning, on-demand cleaning, or off. This switch is supplied
factory wired as shown in Figure 4. The switch has a front and rear
section. The front section, consisting of two independant contacts,
controls the power to the board. These contacts must be wired in
parallel as shown in the diagram. The rear section controls the
manual override, which when closed will force the system into a
continuousmuct be reconneccted, follow the wiring diagram.
Caution: Do not interconnect the low voltage manual over-
ride leads with the power leads. This will destroy the con-
trol board as well as pose a serious shock hazard
2.0 Programming the DCT1000
Master Controller
We've made it easy to navigate the DCT1000. Menu items can be
accessed simply by pressing the "SELECT" button. The menu item
that you are currently accessing is indicated by the illumination of
an LED. To change menu items, all you have to do is push "UP" to
increase a value or push "DOWN" to decrease a value. There are
no keystrokes that you need to memorize, special combinations, or
passwords that are required.
The master controller is equipped with an on board display and
programming information center. The controller will power-up with
the process indicator illuminated. If a pressure module is installed,
the display will indicate the measured pressure in inches of water
(w.c.); otherwise it will normally be blank.

2.1 • Last Output
The Last Output setup selects the last channel to be activated.
When first selected, the display will flash the last output available in
the system. With single board installations, this will be the number
of channels installed, typically 6, 10 or 22. This value becomes
more important when multiple modules are installed. The last out-
put value flashed will be the sum of all channels available in the sys-
tem.
After the last available channel indication has completed, the cur-
rently programmed last channel value is displayed. This value may
be changed using the "UP" and "DOWN" buttons. The minimum
value is one while the maximum value is the maximum number of
installed channels, including all expansion modules.
The default value is the maximum number of channels. Pressing
"SELECT" will change the setup mode to Time Off Setup.
2.2 • Time Off (Sec.)
Time off defines the period of time between solenoid activations
when no channels are enabled. This may be set between one sec-
ond and 255 seconds. The factory default is 10 seconds. The dis-
play will show the current time off setting when the time off setup
mode is entered. The value may be changed using the Up and
Down buttons. Pressing both "UP" and "DOWN" simultaneously
and holding for approximately four seconds will restore the default
value of 10.
2.3 • Time On (msec)
Time On Setup sets the solenoid on time. The display will indicate
the currently programmed time on setting. This is measured in mil-
liseconds. Using the "UP" and "DOWN" buttons, the value may be
changed. The value may be set between 10 msec and 600 msec
in 10 msec increments. Pressing the "UP" and "DOWN" buttons
simultaneously for approximately four seconds will restore the fac-
tory default value of 100 msec. Pressing the "SELECT' button will
advance the setup mode to the High Limit setup if the pressure
module is installed. With no pressure module, it will step to Cycle
Delay Setup.
