Introduction

The Series DCT500ADC Timer Controller is a timing system for pulse-jet type dust

collectors or pneumatic conveying systems in either continuous or on-demand clean-

ing applications. It is provided with either 4, 6, or 10 channels. The DCT500ADC was

designed for ease of installation in your dust collector system. For installations requir-

ing fewer channels than available on the board, a shorting plug is provided to allow

selection of the last used channel. Time-on and time-off settings are selected using

two potentiometers. High-limit and low-limit control inputs are provided for use with

on-demand systems. When used in a continuous mode the high-limit input is

jumpered.

Installation

Warning: Always replace the fuse with the proper type and rating.

The fuse is Type 3 AG fast acting 3 Amp @ 250V. DO NOT use slow-

blow type fuses. Failure to comply with this requirement will void man-

ufacturer’s warranty.

This equipment is intended to be powered using a recognized Class 2

power supply. If powered from a DC bus a suitable transient protection

device meeting Installation Category II requirements must be used.

Protection provided by the equipment may be impaired if the equipment

is used with accessories not provided or recommended by the manu-

facturer, or is used in a manner not specified by the manufacturer.

Power Requirements

The DCT500ADC Series controller is designed for operation with a DC power supply.

The supply voltage must be between 10 VDC and 35 VDC. Exceeding 35 VDC may

damage the unit. The solenoid outputs are driven from the power supply so the sole-

noids must be rated for operation at the power supply voltage. The solenoids are

connected as shown in the wiring diagram and must not be connected to any other

external circuit. The solenoid common is the positive (+) lead and is internally con-

nected to the fused positive (+) supply. The individual outputs are switched to the

negative (-) supply input through an open drain field effect transistor (FET). The out-

puts are protected for inductive flyback transients of the solenoids.

Location

The system must be located in an enclosure that meets relevant safety standards and

electrical codes. There are no other special orientation requirements. Mount it using

the four mounting holes in the baseplate. The baseplate back is flush, so no special

spacers are needed to accommodate obstructions except for those imposed by the

location itself.

Connections

The power and solenoid connections are located at the lower edge of the board. The

terminal block is a “Euro” style connector system that clamps the wire within the con-

nector body. The connector will accept wire sizes from 14 to 22 gages. These termi-

nals should be torqued to 5 in. lb. The connectors are specified for single connection

but multiple wires may be connected to a single lug provided local codes allow this

and good workmanship practices are followed. When using stranded wire, make sure

that there are no “stray” strands. These may cause system failure or damage.

Connect the (+) (-) power to (+) and (-). Connect the solenoids between the selected

output and the solenoid common. Solenoid common and (+) are internally connect-

ed through fuse. Refer to Figure 2-1.

The wire should be stripped to no more than 0.25 in. A strip gauge is provided at the

lower right corner of the board. Longer than this may cause shorts. Switches con-

nected to the control inputs at the top of the board must be isolated normally open

contacts connected only to the relevant terminal and to the common terminals.

The following subparagraphs describe the external switch connections. Refer to fig-

ure 2-1 for switch connection illustration.
