Models T2310 and T2320 are micro­processor-based bag house filter controllers
which combine a ten or twenty output
sequencer with a solid state differential
pressure sensor. This offers a small, low­cost replacement to the separate solid state
sequencer and pressure gauge combination
most often used in on-demand pulse jet
cleaning systems. These controllers will
sense the pressure difference across the
filters of a bag house and initiate a cleaning

File #E65038

-

-

cycle when the filters start to impede the air
flow. When the pressure drops to normal the
controller will stop cycling.

Standard Operating Logic: The timers can
operate in the following modes:

●

Auto output: only configured outputs will
be pulsed. Output faults will be detected
and indicated.

●

Manual output: outputs will recycle after
last output used.

●

Output step: a single cleaning pulse can

-

be initiated by pressing the output step
key regardless of pressure input.

●

Continuous cycle: controller will cycle
indefinitely when the bypass/cycle down
input is shorted.

-

●

Cycle down: the outputs will be pulsed
through a user seleced number of com
plete cycles when the bypass/cycle down
input is shorted. This cycle will occur
regardless of pressure input.

Expanded output mode: controller will

●

cycle to output #10 or #20, then will ini
tiate an extended output mode via the
alarm input and output terminals to
NCC’s DNC-T2000 series dust collec
tor controllers. This will facilitate sys
tems which require greater than 10 or 20
outputs.

Standard Timer Operation Status
Indication: The Timer can show the follow-

ing information on its 8-character alpha­numeric display during normal operation:

●

DP from 0” to 15” water column

●

High or Low DP Alarms

●

Solenoid Fault Conditions

●

Current Output being Pulsed

●

-

Auxiliary Alarm Input Closures

Upon occurance of any alarm event, the
alarm status is reported on the display
along with the output number that was
pulsed during the time of the event.

●

Alarm Outputs: The isolated Alarm
Output contacts will close for alarm
conditions such as output faults,
high pressure alarm, warm-up failure,
etc. During an alarm condition, a
corresponding message is displayed.

●

Alarm Input: A closure across the Alarm
Input terminals will be indicated on
the display as well as initiate the Alarm
Output.

In addition to the standard opera­tion of the T2310 and T2320,
an enhanced operation option

-

is available with the use of the
DNC-T2300-I/O Remote Input/
Output module in conjunction
with the DNC-T2300-DSP Remote
Annunciator Panel. The T2310

-

and T2320 Timers along with the
DNC-T2300-I/O constitutes the

-

-

Enhanced Timer system which
allows the user to monitor and
record the data parameters associ
ated with a dust collector system.
This system can range in size from
1 to 255 dust collectors, all report
ing to a central location, the DNC­T2300-DSP.

Enhanced Timer Operation
Status Indication: The Timer can

show the following information on
its 8 character alpha-numeric dis
play during normal operation:

DP from 0” to 15” water column

Remote Terminal: An ANSI type ter

●

minal is required for remote monitor
ing and programming of the controller.
Connection to the controller is made via
the RS232 port (9 pin D-Sub connec
tor). All the functions and display status
accessible from the controller are avail
able through the ANSI terminal.

Remote I/O Interface: The 2310/2320

●

controllers are capable of communication
with the DNC-T2300-I/O board via the
RS232 port. This allows the user to moni
tor up to three 4-20 mA analog inputs,
three contact closure type inputs, and
one Type J thermocouple. The I/O mod
ule is programmed via the 2310/2320
keypad and can be user defined to set
alarm points from remote sensors of
parameters such as emission, air flow,
pressure, broken bags, fan motor current,
etc. Refer to the data sheet for the DNC­T2300-I/O for additional information.

Programming Logic: The controller as sup

­figuration. Upon application of power the
display will indicate SETUP. The operator
must then configure the various operating
parameters using the six key keyboard of
the controller before normal cleaning opera
tion can begin. The programmable param

­eters for Standard Operation as displayed
are:

●

Auto Configuration: will automatically
sense the solenoids connected to the
outputs and will only pulse those outputs
during cleaning cycles.
Manual Configuration: the controller will
pulse each output until the last output
programmed and then recycle to output

Caution:

1. Do not mount controls in high vibration areas with
out shock mounts.

2. Do not mount controls in areas of high dust or cor

-

rosive atmospheres without a protective enclosure.
3 Do not use a converter or inverter for the power

source.

4. Do not mount control in high transient voltage

-

areas without an isolation transformer.

5. Do not leave control box open.

6. Do not allow a local repair shop to repair the con
trols, as we employ some very sophisticated compo
nents that could be further damaged. For service, call
us directly: 800-323-2593.
