DNC-T2320 Shown
 

Standard Operating Logic The controllers 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
• Single Cycle Output
  Single cycle cleaning can be initiated by keypress regardless of pressure input
• Continuous Cycle
  Controller will cycle indefinitely when the Pressure Bypass/Cycle Down Input is shorted
• Cycle Down
  The outputs will be pulsed through a user seleced number of complete 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 initiate an extended output mode via the Alarm Input and Output terminals to NCC's DNC-T2000 Series Dust Collector Controllers. This will facilitate systems which require greater than 10 or 20 outputs.
• 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 & 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 & 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 associated with a dust collector system. This system can range in size from 1 to 255 dust collectors, all reporting to a central location, the DNC-T2300-DSP.

Enhanced Timer Operation Status Indication: The Timer can show the following information on its 8 character alpha-numeric 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 · DNC-T2300-I/O Analog Input Status · DNC-T2300-I/O 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.
RS-232 Port:

• Remote Terminal
  An ANSI type terminal is required for remote monitoring and programming of the controller. Connection to the controller is made via the RS-232 port (9 pin D-Sub connector). All the functions and display status accessible from the controller is available 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 RS-232 port. This allows the user to monitor up to three 4-20mA analog inputs, three contact closure type inputs, and one J type thermocouple. The I/O module 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 DNC-T2300-I/O for additional information.

Programming Logic: The controller as supplied from the factory will require user configuration. 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 operation can begin. The programmable parameters for Standard Operation as displayed are:

• OUTPUT
  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 #1
• LAST - the number of the last output used.
• LO P - Low Pressure Setpoint, the pressure at which the controller will stop its cleaning cycle.
• HI P - High Pressure Setpoint, the pressure at which the controller will start its cleaning cycle.
• ON - Output Solenoid On Time.
• OFF - Off Delay Time Between Output Solenoid Activation.
• ALARM - High Differential Pressure Alarm Set-Point, the pressure at which the controller will close its alarm contacts

For Enhanced Timer programming information, see IDC Programming Tree on PDF Catalog page.

Additional Features:The 2310/2320 controllers also provide:

• 4 - 20 Milliampre Output Loop
  This output will provide a continuous reading from 4 -20 mA corresponding to the sensed differential pressure range of 0" to 15" water column.This is a standard feature.
• 24 Hour Time / Day / Month Clock The clock feature will allow a daily automatic turn on and turn off command to be implemented by the controller. It can be programmed to start and stop the cleaning cycles for up to seven events per week. This is an optional feature found on the "B" series models
