Microprocessor-driven digital Aalborg SDPROC command modules are used in conjunction with any analog or digital mass flow meters or controllers with 0-5VDC input/output signals. One, two, three, and four channel Aalborg SDPROC command module configurations are available. Aalborg SDPROC command modules contain appropriate power supplies, 24x2 alpha-numeric dot matrix display readout, and four panel buttons which provide complete control over all the various functions necessary to measure and/or control flow.

Programming the Aalborg SDPROC Command Module
It is easy to program the SMART Aalborg SDPROC command module using a logically organized, modular menu. The operator quickly accesses a desired function by branching through the multi-level tree structure rather than scrolling through the entire menu. The Aalborg SDPROC command module features a RS-232 serial communication interface that is standard for all models and supported via a 9-pin "D"-connector on the back panel of the unit. The RS-232 software interface commands set allows communications with the unit using either a custom software program or a "dumb terminal", providing complete control over all modes and functions.

The optional built-in Ethernet interface allows accessing any internet-connected Aalborg SDPROC command module from a browser on your work station, PC, or laptop computer. Regardless of where you are, your Aalborg SDPROC command module is as close as the nearest browser! There are two levels of Ethernet-based Remote Controls: HTML web server and TELNET. The HTML web server, which is hosted on the Aalborg SDPROC command module allows the user view CURRENT FLOW RATE, CONTROL VALVE MODE and/or SET POINT, MONITOR TOTALIZER READING FOR SELECTED CHANNEL. The TELNET console provides complete control over all modes and functions and using the same Software interface commands set as the RS-232 communication interface.

Engineering Units
The flow set points, measured gas flow, and associated totalizer data are scaled directly in engineering units via front panel keypad, RS-232, or Ethernet interface. The following units of measure are supported by the Aalborg SDPROC command module: %F.S., SLPM, SLPH, SCCM, SCCH, SCFM, SCFH, SCMM, SCMH, LBPM, LBPH, GRPM, and GRPH.
User-Selectable Reference for Set Point

The INTERNAL, EXTERNAL, PROGRAM refers to the point of origin for the Set Point signal. In Internal reference mode, the user sets the control signal with SDPROC controls (via front panel keypad, RS-232 or Ethernet interface).

In EXTERNAL REFERENCE MODE, the user sets the control signal from a remote location (via the DATA IN/OUT 25-pin "D"-connector on the rear panel).
In PROGRAM MODE the set point signal will be driven by user's custom program stored in the EEPROM. There are three Program modes: BATCH, TIMER and RATIO*.

* RATIO mode not available for one channel module.

Programmable Batch Flow Control
The Aalborg SDPROC command module can be programmed for Batch Flow Control, which allows execution of custom, user-preset programs of up to sixteen steps. During execution of the program, the user can activate or deactivate the LOOP mode. Various flow configurations may be preprogrammed in the Aalborg SDPROC command module: ramping, pulsing, and linearized increasing and/or decreasing of the flow.

Programmable Timer Flow Control
The Aalborg SDPROC command module can also be programmed for Timer Flow Control allows execution of custom, user-preset program of up to 96 steps. Each step can be preprogrammed for a particular date, time, and set point value. Every step has two fields: starting date, time and set point in % F.S.

Ratio Flow Control
The Ratio Flow function of the Aalborg SDPROC command module allows controlling flow of the mixture of up to four different gases (for 4 channel Command Module) with preset values of the ratio in % for each channel. The flow rate of the mixture can be incremented or decremented by changing the set point of the master channel #1.

Flow Alarms
High and Low gas flow ALARM limits can be preprogrammed for each channel of the Aalborg SDPROC command module. ALARM conditions become true when the difference between current readings and installed set points are equal or more than corresponding values of high and low alarm levels. Alarm action can be assigned with preset delay interval (0-3600 seconds) to one of the following:
  • Contact closer (separate for High and Low alarm)
  • Buzzer Audible Signal
  • Valve shut down (Close)
Totalizer
The Aalborg SDPROC command module calculates the total volume of the gas by integrating the actual gas flow rate with respect to time. Both keypad menu and digital interface commands are provided to:
Set the totalizer to ZERO
Start the totalizer at a preset flow
Assign action at a preset total volume
Start/Stop totalizing the flow

Read totalizer
Totalizer conditions become true, when the totalizer, and the "Stop at Total" volumes are equal. Totalizer action can be assigned to one of the following:
  • Contact closer
  • Buzzer audible signal
  • Valve shut down (Close)
Contact Closures
Two sets of dry contact relay outputs for each channel of the Aalborg SDPROC command module are provided to actuate user supplied equipment. The relays can be assigned to switch when a specified event occurs (e.g. when a low or high flow alarm limit is exceeded or when the totalizer reaches a specified value).

Cables
Interface Cable: Flat cable with male 15-pin "D" connector and female 15-pin "D" connector on the ends is standard. Optional round shielded cable is available with male/female 15-pin "D" connector ends (cable length may not exceed 9.5 feet, or 3 meters).

Data Port and Relay Cable: Optional shielded cable with male 25-pin "D" connector to connect to command module data and relay ports (cable length may not exceed 9.5 feet, or 3 meters).
