Introduction

The Series DCT500A Timer Controller is a timing system for pulse-jet type dust col-

lectors or pneumatic conveying systems in either continuous or on-demand cleaning

applications. It is provided with either 4, 6, or 10 channels. The DCT500 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 jumped.

For safety, the control circuitry including the control inputs and the last channel

jumper, is isolated from the power line.

Installation

Warning: Always install and service this device with the power off

and a lockout installed if required. Line voltages are exposed on the

board. As a result, this device is not intended to be installed in any open

location. It must be installed within an enclosure that meets appropriate

safety and local code requirements. Follow applicable safety proce-

dures when installing or servicing this product.

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 pose a seri-

ous safety risk and will void manufacturer’s warranty.

Warning: As a permanently installed piece of equipment, a power dis-

connect switch, circuit, or other approved disconnect device must be

installed in close proximity to the installed board and within easy reach

of the operator. This disconnect device must include a label indicating

its function as a mains disconnect.

Power Requirements

The controller is designed for operation on 120 VAC 50/60 Hz power. The input volt-

age must be between 102 VAC and 132 VAC either 50 or 60 Hz. The solenoid loads

must be rated for 120 VAC operation.

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.

Installed screws and other mounting hardware must maintain a spacing of 0.250 in

(6.35 mm) from the circuit board.

Connections

The line 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. Wire must be

copper only with at least 60°C or 60/75°C rated insulation. These terminals 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 pose safety hazards and may cause system failure or

damage. Connect the line power to L1 and L2. Connect the solenoids between the

selected output and the solenoid common. Solenoid common and L2 are internally

connected. 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 or expose line volt-

ages to possible contact.

Switches connected to the control inputs at the top of the board must be isolated nor-

mally open contacts connected only to the relevant terminal and to the common ter-

minals.

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

ure 2-1 for switch connection illustration.
