1.0 Installing the DCT1000
Warning: Always install and service this device with the
power off and a lockout installed if required. Line volt-
ages will be exposed at the power/output connector
and at the fuse. For this reason, we have installed a
plastic guard to protect the user from accidentally contacting line
voltages.
Please note that the power guard serves as a safety feature and
should not be removed under any circumstances.
For ease of installation and maintenance, the connectors and fuse
have been left unprotected. The open frame design of the DCT1000
will require an enclosure that meets appropriate safety and local
code requirements. For optimal performance, the enclosure should
also protect the controller from dirt, water and direct sunlight. There
are no special orientation requirements, and the controller mounts
easily using the mounting holes on the factory installed base plate.

leads. The system may malfunction if class 2 wiring is run
together with power conductors.
1.1 Power Requirements
The controller has a "universal" power supply that will allow opera-
tion on 120 VAC to 240 VAC power lines. The input voltage must be
between 85 VAC and 270VAC either 50 or 60 Hz. No circuit
changes are required when switching between these voltages. The
solenoid loads, however, must be sized to accommodate the line
voltage selected.
1.2 DCT1000 Terminal Connections
The line and solenoid connections are located at the lower edge of
the board below the plastic guard. The terminal block is a "Euro"
style connector system that clamps the wire within the connector
body. The connector will accept wire sizes from 14 to 22 AWG. The
wire should be stripped to no more than 0.25 inches to avoid shorts
or expose line voltages creating a potential safety hazard. To assist
you in determining the proper wire gauge required, a strip gauge is
provided at the lower right corner of the board. The connector sys-
tem used on the DCT1000 is specified for single connection but you
can piggyback to a single lug provided that local codes allow for this
and good workmanship practices are followed. To power up the
master controller and the channel expander, connect line power to
L1 and L2 (see Dimensional Specifications, Figure 1). Connect the
solenoids between the selected output and the solenoid common.
Solenoid common and L2 are internally connected. Switches con-
nected to the control inputs at the top of the board must be isolat-
ed contacts connected only to the relevant terminal and to the com-
mon terminals. The following subparagraphs describe the external
switch connections. Refer to figure 2 for switch connection illustra-
tion.
1.2.1 External Pressure Connection
The controller may be used with an external pressure limit switch or
sensor to provide demand-cleaning operation. The high limit and
low limit inputs may be used for this purpose. A simple on-off sys-
tem can be established with a single pressure switch connected to
the high limit input. Better control can be achieved with a high and
low limit switch/gage such as the Dwyer Photohelic
demand mode, time on, time off, and cycle delay may be pro-
grammed to define the cleaning cycle. A three pin terminal block
(TB3) provides connection for external high and low limit switches
(see Figure 2 on the next page). These switches must be isolated
contacts. The common line must not be connected to equipment
ground or protective ground, since these may introduce electrical
noise and cause improper operation or possible damage to the con-
trol board. The operation of these inputs are summarized as follows
