OVERVIEW

The Model T2310 and T2320 Series are microprocessor based
Pulse-Jet Bag House Dust Collector Controllers. Their purpose is
to monitor the differential pressure across the dust collectors’ bag
assembly. If the differential pressure exceeds the high-pressure set
point, the controller will initiate a cleaning cycle.

During a cleaning cycle, the controller pulses the solenoids con­nected to its outputs sequentially. The solenoids in turn, will pulse
high-pressure air to the filter compartments in the dust collector.
The high-pressure air blast is used to clean the filters. The pulsing
of the solenoids will continue until the differential pressure drops
below the low-pressure setpoint. At this time the solenoids will stop
firing.

The controller keeps track of the last output fired. When the
pressure rises above the high-pressure set point again, it will start
the cleaning cycle with the next output to fire.

When the controller is in the auto learning mode, it has the ability
to learn which outputs have solenoids connected to them. If the
controller does not sense a solenoid connected to an output, it will
skip over that output.

During normal operation, the solenoids are constantly being
monitored. If a solenoid circuit is open or an output is stuck
"on", the controller shall signal that an alarm condition occurred.
Furthermore, as a troubleshooting aid, the display shall indicate
which output is faulty.

2.0 ELECTRICAL HOOKUP

NOTE: To aid in installation, refer to the corresponding wiring diagram.

Connect this unit to the correct power source, which is listed
on the nameplate. Do not connect this unit to a "converter" or
"inverter" type power source. This unit should be installed on
its own 15-amp circuit. Do not connect this unit to a power
source that is subjected to large switched loads, such as, electric
motors, compressors, electric tools, etc.

WARNING: MAKE SURE THAT THE CIRCUIT THAT YOU ARE
WORKING WITH, IS "TURNED OFF", BEFORE YOU MAKE
THESE CONNECTIONS. SERIOUS INJURY MAY RESULT IF YOU
DO NOT TAKE THE PROPER SAFETY PRECAUTIONS.

On 120 volt models connect the "hot" or "high side" of the
incoming power source to "L1" on the terminal strip. Connect
the "return" to "L2" on the terminal strip.

On 220-volt models, connect one side of the 220-volt line to L1
and connect the other side of the 220-volt line to L2.

Connect the solenoid air valves to the terminal strip. These are
labeled with the word "OUTPUTS" and they are numbered 1
through 10 for the T2310 unit and 1 through 20 for the T2320
unit. You can connect more than one solenoid on each output,
as long as you do not exceed the 200VA (Watt) rating on each
output.

The return wires "commons" from the solenoids will return to
the "SOL COM" connection on the terminal strip.

3.0 ALARM INPUT CONNECTION

CAUTION: DO NOT APPLY ANY TYPE OF LIVE POWER TO
THIS ALARM INPUT. SEVERE DAMAGE TO THE UNIT WILL
OCCUR.

It is recommended that you do not run this wiring in conduit
or cabling raceways, which have high voltage or high current
conductors. It is also recommended that you use a twisted wire
pair for this connection.

3.2 T2320 Models:

There are 4 general-purpose alarm inputs on the DNC­T2320-A10 and -A220 controllers. The DNC-T2320-B10 and

-B220 controllers which have the Real Time Clock installed, do
not have alarm inputs #2 and #3 available.

Alarm inputs 1, 2, and 3 will accept any type of sensor, which
has a "normally open, dry contact" switch output. The switch
or contact closure must be suitable for, 24VDC at .010 amps.
A switch or contact closure will indicate an alarm condition to
the controller.

CAUTION: DO NOT APPLY ANY TYPE OF LIVE POWER TO
ALARM INPUTS #1,2, OR 3. SEVERE DAMAGE TO THE UNIT
WILL OCCUR.

"ALARM AUX INPUT #4" is a dual-purpose input. It can
be used as a general alarm input or as the input for the
"EXPANDED MODE" feature, which is described in Expanded
Mode Section. As an alarm input, it requires a switched line
voltage input, 120VAC 50/60 Hz source for the -A10 and -B10
models and 220VAC 50/60 Hz source for the -A220 and -B220
models.

3.1 T2310 Models:

There are three general "ALARM INPUT" connections on the
DNC-T2310-A10 / A220 models and one general "ALARM
INPUT" on the DNC-T2310-B10 / B220. You can connect any
type of sensor to these inputs, which has a "normally open, dry
contact" switch output. The switch or contact on your equip­ment must be suitable for, 24VDC at .010 amps. A switch or
contact closure will indicate an alarm condition to the control­ler

T2310 / T2320 Operation Manual Page 8

CAUTION: DO NOT APPLY ANY OTHER VOLTAGE EXCEPT
AS SPECIFIED ABOVE, TO THIS INPUT. DAMAGE TO THE
CONTROLLER WILL OCCUR.

It is recommended that you do not run this wiring in conduit or
cabling raceways, which have high voltage or high current conductors.
It is also recommended that you use a twisted wire pair for this
connection.

4.0 ALARM OUTPUT CONNECTION

The "ALARM OUTPUT" connection is used to indicate to a
remote location that an alarm has occurred. All alarms that are
generated by the controller, including ALARM INPUTS #1, 2,
and 3, will activate this output.

This output is a set of "normally open" relay contacts. It is
capable of switching 3 amps at 120/240 VAC. When the con­troller has an alarm condition, the contacts will close.

The AUX INPUT #4 only controls the AUX OUTPUT #4 on the
T2320 models only. No other alarms will activate this output.
The relay contacts have the same rating as the output for
alarms #1, 2, and 3. A red LED located next to the alarm output
will light when the relay contacts are closed.

It is recommended that you do not run this wiring in conductor
cabling raceways, which have high voltage or high current
conductors. It is also recommended that you use a twisted pair
wire combination for this connection.

5.0 BYPASS/CYCLE DOWN INPUT CONNECTION

5.1 CYCLE DOWN MODE:

The Cycle Down mode allows the user to connect an auxiliary
set of contacts from the ventilation fan in the dust collector to
the Bypass/Cycle Down Input of the “Intelligent” controller in
order to clean the filters “off-line” when the fan shuts down.

If the Cycle Down mode is enabled, normal operation of the
controller occurs when the Bypass/Cycle Down Input is short­ed; opening the Bypass/Cycle Down Input will begin a "POWER
CYCLE DELAY" time and will inhibit any cleaning cycles due
to the differential pressure. The display will alternate the words
"POWER", "CYCLE", "DELAY" and "∆P =XX.X".

At the end of this delay, the unit will cycle through all the
selected outputs as determined by the number of cycles select­ed with the "NO_ CYL XX" programming menu item, beginning
at output number 1. If the unit is being used in expanded
mode, the cleaning cycle of the Cycle Down mode will start
on the external board. When the Bypass/Cycle Down Input is
closed, the unit shall resume normal operation.

5.2 BYPASS MODE:

If the Bypass/Cycle Down Input is shorted with the Cycle Down
mode disabled, a cleaning cycle shall be initiated regardless of
the value of the sensed pressure and will continue until the
circuit is opened. Once the input is opened the cleaning cycle
will either stop or continue based on the value of the sensed
pressure as previously defined.

CAUTION: DO NOT APPLY ANY TYPE OF LIVE POWER TO
THIS BYPASS/CYCLE DOWN INPUT. SEVERE DAMAGE TO THE
UNIT WILL OCCUR.

NOTE: The "ALARM INPUTS", "ALARM OUTPUT", and "BYPASS/CYCLE

DOWN INPUT" do not need to be connected for the operation of the
controller. These connections are optional.

6.0 PRESSURE CONNECTIONS

The controller is equipped with a metal manifold, which is used
to make the differential pressure connections. The manifold is
tapped for 1/8-27 NPT, female pipe fitting.

It is recommended that the tubing be run through a bulkhead
fitting on the NEMA enclosure. This will provide a seal to pre­vent moisture, dust and particulates from entering the enclo­sure.

Connect the "HIGH SIDE" or “dirty air” pressure connection
to the inlet of the dust collector. Do not make sharp bends
or kink the tubing when installing. Follow the manufacturers'
installation instructions for the placement of the input pressure
tubing.

CAUTION: THE MAXIMUM PRESSURE THAT CAN BE APPLIED
TO THE PRESSURE INPUTS IS 10 PSI. ANY GREATER
APPLIED PRESSURE, EVEN MOMENTARILY, WILL DAMAGE
THE PRESSURE SENSOR.

Connect the "LOW SIDE" or “clean air” pressure connection
to the outlet of the dust collector. Do not make sharp bends
or kink the tubing when installing. Follow the manufacturers'
installation instructions for the placement of the output pres­sure tubing.

7.0 4 TO 20 MILLIAMP CURRENT LOOP

The "4-20mA" output is used for a remote indication of differ­ential pressure. Zero inches of differential pressure will produce
4 milliamps at this output; fifteen inches of differential pressure
will produce 20 milliamps.

There is a plus (+) and minus (-) connection for this output.
Make sure that you observe the polarities when you make the
connections to your equipment.

It is recommended that you do not run this wiring in conductor
cabling raceways, which have high voltage or high current
conductors. It is also recommended that you a twisted pair wire
combination for this connection.

8.0 BEFORE APPLYING POWER TO THE UNIT

■ Recheck all of your electrical connections.

■ Recheck all of your mechanical and pressure

connections.

■ Turn on the circuit breaker.

■ Observe the display on the controller, the word "SETUP" should be on

the display. If not, ignore the message on the display.

9.0 TROUBLESHOOTING

If the display does not show a message after the application of
power, check the following:

■ Check the wiring from the circuit breaker to L1 and L2 on the

controller.

■ Check the fuse on the controller. A blown fuse on the controller

may indicate a problem with the solenoid outputs. Recheck the
connections to the solenoids.

■ A short in the solenoid wiring or a short in a solenoid itself may

not cause the fuse to blow during setup of the controller. If there
is a problem with an output, the fuse may blow during the auto
configuration of the outputs or during the first cleaning cycle.

■ Verify that the correct circuit breaker was turned on.

CAUTION: THE FUSE THAT IS INSTALLED ON THE
CONTROLLER IS A FAST-BLOW FUSE. DO NOT USE A SLOW­BLOW OR A LARGER SIZE FUSE. FAILURE TO COMPLY WILL
VOID ANY WARRANTY.

10.0 "SETUP" MODE

After the application of power to a new controller, the word
"SETUP" should be on the display. The controller is shipped
in this mode so that all the programmable parameters are
reviewed before the system is placed in operation.

If you see the message "∆P =xx.x", which is the current dif­ferential pressure, this may indicate that the unit has been
previously configured. If you do not have the "SETUP" mode
message and you want to reset the controller to this mode refer
to the section for Reloading Factory Defaults for instructions.
