The UP button under the “+” and DOWN button under the “-” will increase and decrease the set point respectively.
e.3.7 Setup Channel Display Pressing the Down button under Main Display screen (see section e.3.2) will display SETUP CHANNEL screen shown below. Setup Channel Display for Multi channel SDPROC Press the button on the SDPROC panel under the appropriate channel number displayed. This will select that channel for device settings configuration. (For this manual, channel 3 has been selected.) The following display will appear. Setup Channel screen allows to configure: = GENERAL DEVICE SETTINGS: Int./Ext.
e.3.7.2 Setup Gas Density Display The proper settings of the gas density (in grams per liter) are required for mass based engineering units (LBPH, LBPM, GrPH, GrPM). Press the ENTER button under (--->) on the display, to move the flashing cursor to the desired position. Pressing (+) or (-) will increment or decrement a particular digit respectively. The numbers will change from 0 to 9 and next to the decimal point (.).
change the decimal point to any desired digit, next move the cursor to the required position, and adjust it to the decimal point with the (+) or (-) button. When complete with Full Scale Flow Rate settings, press the ESC button under NEXT on the display, to go to the Relays Assignment screen. The following Setup Relays Assignment Display will appear. e.3.7.5 Setup Relays Assignment Display Two sets of dry contact relay are available for each channel.
NEXT on the display to go to the Alarm Low settings. The following Setup Alarm Low Display will appear. e.3.8.2 Setup Alarm Low Display Pressing (+) or (-) will increment or decrement Low Alarm settings per 0.1% F.S. respectively. If no settings are required for High Alarm press the ENTER button under EXIT on the display, to go back to the Main Display. Press the ESC button under NEXT on the display to go to the Alarm High settings. The following Setup Alarm Low Display will appear. e.3.8.
In order to deactivate the audible signal during operation, press any button on the key pad (NOTE: Alarm Conditions have to be removed or Alarm for the corresponding channel has to be disabled). If Valve action is chosen the power to the mass flow controller valve will be shut off, allowing the valve to mechanically close. If the Valve was shut off as the result of the Alarm action, in order to go back to normal operation the Valve mode has to be changed to AUTO (See section e.3.5).
under NEXT on the display to go to the Totalizer Stop settings. The following Setup Totalizer Stop Volume Display will appear. e.3.9.3 Setup Totalizer Stop Volume Display The proper setting of the Totalizer Stop Volume (in volume/mass based engineering units) is required if the Totalizer is set to Enabled. The engineering unit for Totalizer Stop Volume has to be related to the current active engineering unit.
There are three program options for multi channel SDPROC: BATCH, TIMER and RATIO flow control. e.3.10.1 Batch Program Settings Display Batch Flow Control allows execution of a custom, user preset program of up to sixteen steps. During execution of the program the user can activate or deactivate the LOOP mode. Various flow configurations may be pre-programmed: ramping, pulsing, linearized increasing and/or decreasing of the flow.
BATCH mode control screen with batch disabled The two digit number after “SE:” indicates the number of the enabled steps for executions. Press the UP button under STEPS on the display, to change the number of steps from the batch program to be executed. With 16 steps enabled on the screen, pressing the Up button one more time will rollover the number of steps back to 1. Press the ENTER button under LOOP on the display, to toggle the loop control ON and OFF.
the ENTER button to move the flashing cursor to the date position (month, date and year) respectively. Make sure date and time entered is not in the past (otherwise this step of the program will not be executed). When complete with TIME and DATE settings for first step of the Timer program, press the ESC button under NEXT on the display, to go to the SETPOINT screen. The following display will appear.
By default, Ratio Mode is disabled for each channel. In order to be able to enable Ratio Mode, the value of the ratio in % for a particular channel has to be more than 0%. It is recommended to begin Ratio settings from the master channel #1 (master channel has to be set to the highest value from the mixture). For example, if four gas mixtures are desired with ratios: Gas#1=30%, Gas#2= 25%, Gas#3=25% and Gas#4=20% the Gas#1 has to be set on channel#1 (master channel).
Make sure that the total value of the mixture is equal to 100% in the end of the ratio settings for all required channels. When complete with ratio value settings for all required channels, go to the ratio mode settings screen for each required channel and change the ratio mode from DISABLED to ENABLED. Make sure that the reference for set point is set to PROGRAM RATIO mode for all required channels in order for the Ratio program to be executed (see section e.3.7.1).
e.3.12 Real-time Clock Settings Real Time Clock Settings Display for SDPROC Normally date and time for the Real-time Clock are set by the factory, unless the battery was replaced, or the CPU core was removed from the main board of the SDPROC. In order to change date and time settings press the ENTER button under SET on the display. This will activate the flashing cursor on the hours position. Pressing (+) or (-) will increment or decrement the time settings (hours).
Pressing the UP button again will bring up the Alarm Mode Status for all channels. Alarm Mode Status Display for Multi channel SDPROC Pressing the UP button again will bring up the Totalizer Mode Status for all channels. Totalizer Mode Status Display for Multi channel SDPROC Press UP one more time to return to the Main Display. NOTE: Pressing the Down button from any of the status screens will switch status display to one step back. (f) MAINTENANCE The SDPROC does not require any regular maintenance.
Calibration Mode Display Proceed with instructions outlined in sections g.1 and g.2. g.1 Digital to Analog (D/A) Slope Calibration Select the D/A calibration mode from the Calibration Menu. The following display will appear. The digital to analog (D/A) slope has to be calibrated for each channel , NOTE: individually! Using an accurate digital multimeter, measure the A/D output DC voltage between pins 9 (positive) and 10 (ground) of the Channel 1 15 pin “D” connector.
The display should show the D/A value between 3900 and 4095. Save the D/A slope parameter by pressing the CAL (ENTER button).Proceed with D/A calibration for as many channels as required. When digital to analog (D/A) slope is calibrated for last available channel, the following display will appear. g.2 Analog to Digital (A/D) Calibration Select the A/D calibration mode from the Calibration Menu. The following display will appear. Connect exactly 5.
Press any key when done with 5.000 Vdc connections. The following display will appear. The display should show the A/D offset values between 3850 and 4095. If any value is outside of those limits, the PC board is defective. Save the A/D offset parameters by pressing the CAL (ENTER button). The following display will appear. Calibration of the SDPROC is complete. Press any key to return to the Calibration Mode Display, then press the EXIT button to return to the Main Display.
The protocol described below allows for communications with the unit using either a custom software program or a “dumb terminal.” All values are sent as printable ASCII characters. The command parameters are delimited by a space character and the command string is always terminated with a carriage return character, (line feeds are automatically stripped out by the SDPROC). The structure of the command string: Cmd Arg1 Arg2 Arg3 Arg4 [CR] Where: Cmd The two or three characters command from the table below.

(i) Network Communication Interface (optional) i.1 10Base-T RJ-45 Pinout The optional 10Base-T Ethernet network (RJ-45) system is used in the SDPROC for network connectivity. The 10 Mbps twisted-pair Ethernet system operates over two pairs of wires. One pair is used for receiving data and the other pair is used for transmitting data. Total four pins of the eight-pin connector is used.
i.2.2 DNS DNS, Domain Name System enables individual computers and devices to be recognized over the network base on specific name instead of an IP address. For example, instead of having to use http://192.168.1.19 (which is device IP address), we can use only http://sdproc or any eight characters name stored as the Host Name in the SDPROC. By default each device shipped with Host Name: sdproc.
