b.2 Electrical Connections
b.2.1 Connecting Flow Transducers
Attach the 15 pin “D” connector cable(s) between the interface panel on the rear of the
SDPROC and the Flow Meter/Controller transducer(s). (Number of channels will vary
from one to four in accordance with configuration and options purchased.)
Figure b-1, Interface Panel for SDPROC.
No connection with the DATA IN/OUT, RELAYS or RS 232 connector is required for
operating the system. However, it may be desirable to perform remote monitoring or
control of the flow transducers. In this case, see the pin out chart for the “DATA
IN/OUT” connector in step b.2.4.
Important Notes:
Assure that the “Flow Transducer” cables are used in accordance with configuration
and options purchased.
In general, “D” Connector numbering patterns are standardized. There are, however,
some connectors with nonconforming patterns and the numbering sequence on your
mating connector may or may not coincide with the numbering sequence shown in our
pin configuration table above. It is imperative that the appropriate wires are matched in
accordance with the correct sequence regardless of the particular numbers displayed
on your mating connector, see the pin out chart for the “Flow Transducers” connector.
Power must be shut OFF when connecting or disconnecting any cables in the system.
Cable lengths for Flow Transducers and DATA IN/OUT may not exceed 9.5 feet (3 meters).

Use of the SDPROC in a manner other than that specified in this manual or in writing
from Aalborg7, may impair the protection provided by the equipment.
Figure b-2, Pin out chart for CHANNEL l/2/3/4 “Flow Transducers” connector.
b.2.2 Power Input
Make sure the POWER switch on the back of the SDPROC is OFF. On one end of the AC
line cord is a universal connector that will fit securely into the AC inlet receptacle at the
rear of the SDPROC. Make this connection. Per your specifications at the time of your
order, on the opposite end of the AC line cord is a plug compatible with the AC power
receptacle you intend to use for AC power supply. Make this connection to the AC
power supply receptacle. The SDPROC is capable of receiving 85VAC to 240VAC and
50/60Hz power without any need for jumpering or compensation.
 Use only the AC power line cord supplied with the instrument. Do not attempt to
force or manipulate the plugs of the AC line cord in any way. If it does not fit
easily and securely, contact your distributor or Aalborg7.

has to be adjusted. Pressing (+) or (-) will increment or decrement the particular digit
respectively. The numbers will change from 0 to 9 and next to the decimal point (.).
Pressing the (+) button one more time will change the highlighted position of the cursor
back to 0. The same is true in reverse direction when pressing the (-) button. Only one
decimal point is allowed. If changing the position of the decimal point is required, change
decimal point to any desired digit, then move the cursor to the required position, and
adjust it to the decimal point with (+) or (-) button. When complete with Totalizer Stop
Volume settings, press the ESC button under NEXT on the display, to go to the Totalizer
Action screen. The following Setup Totalizer Action Display will appear.

To change Totalizer Action in NONE, BUZZER or VALVE, press the button (ESC, UP,
DOWN respectively) directly below the text shown on the display. If Buzzer action is
chosen, the audible signal will be activated when Totalizer conditions become true.
In order to deactivate the audible signal during operation press any button on
the key pad (NOTE: The Totalizer has to be reset to zero or 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 a result of the Totalizer action, in order to go back
to normal operation the Valve mode has to be changed to AUTO (See section
e.2.3). NOTE: The Totalizer reading has to be reset to zero or Totalizer has to be
disabled prior any attempts to change the Valve mode.
To return to the Main Display, press the ENTER button under EXIT on the display.
e.2.9 Program Settings Display
From the Setup Channel Display (see section e.2.6) press the Enter button under PROG
on the display in order to make Program settings. The following display will appear.
There are two program options: BATCH and TIMER flow control.
e.2.9.1 Batch Program Settings Display
The Batch Flow Control allows execution of custom, user preset programs of up to six-
teen steps. During execution of the program the user can activate or deactivate the
LOOP mode. Various flow configurations may be preprogrammed: ramping, pulsing,
linearized increasing and/or decreasing of the flow. Before executing, the program
should be entered in the program table in the format: SETPOINT [% F.S.] - TIME [sec.].
TIME means: time it takes for the value of the output signal from mass flow controller
to linearly approach the SETPOINT value (ramping). Press the DOWN button under
BATCH on the display, to set up the BATCH table. The following display will appear.
Time Settings for first step of the BATCH table
Pressing (+) or (-) will increment or decrement the step time settings per 1, 10 or 100
seconds (depending on the value of the multiplier M) respectively. The maximum valid
value is 99999 seconds. Pressing the (+) button one more time will rollover time set-
tings to zero.
