1.0 Installing the DCT1000DC
The open frame design of the DCT1000DC 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.
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 DCT1000DC requires 10 to 30 VDC supply power. The solenoids
must be matched to supply voltage.
DO NOT
exceed 35V, because
transient suppression circuitry will begin to draw high current.
1.2 DCT1000DC 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. To assist you in
determining the proper strip length, a strip gauge is provided at the lower
right corner of the board. The connector system used on the DCT1000DC
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 (+) and (-) (see Dimensional Specifications, Figure
1). Connect the solenoids between the selected output and the solenoid
common. Solenoid common and (+) are internally connected. Switches
connected to the control inputs at the top of the board must be isolated
contacts connected only to the relevant terminal and to the common
terminals. The following subparagraphs describe the external switch
connections. Refer to figure 2 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 pressure switch connected to the high limit input.
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 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 control board. The operation of these
inputs are summarized as follows (see next page):
Ø Transition from open to closed
≠Transition closed to open
X Either open or closed
Note:
If a DCP100A or DCP200A pressure module is installed in the
master controller, the switching functions are ignored.
