1.0 Installing the DCT1000
Warning: Always install and service this device with
the power off and a lockout installed if required. Line
voltages will be exposed at the power/output con-
nector 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 appropri-
ate safety and local code requirements. For optimal perform-
ance, the enclosure should also protect the controller from
dirt, water and direct sunlight. There are no special orienta-
tion requirements, and the controller mounts easily using the
mounting holes on the factory installed base plate.
Caution: Do not run control wires, communication
cables, or other class 2 wiring in the same conduit
as power 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
operation 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 with-
in 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 cre-
ating 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 system
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 specifica-
tions, Figure 2). Connect the solenoids between the selected
output and the solenoid common. Solenoid common and L2
are internally connected. Switches connected to the control
inputs at the top of the board must be isolated contacts con-
nected only to the relevant terminal and to the common ter-
minals. The following subparagraphs describe the external
switch connections. Refer to figure 1 for switch connection
illustration.
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 system can be established with a single pres-
sure 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
® . In this on-demand mode, time on,
time off, and cycle delay may be programmed to define the
cleaning cycle. A three pin terminal block (TB3) provides
connection for external high and low limit switches (see
Figure 1 on the next page). These switches must be isolated
contacts. The common line must not be connected to equip-
ment ground or protective ground, since these may introduce
electrical noise and cause improper operation or possible
damage to the control board. The operation of these inputs
are summarized as follows (see next page):
