Page 12: Dsa3217 - Digital Out Module
DSA3217 - Digital Out Module The DSA3217 - Digital Output Module is a special version of the DSA3217. It incorporates a special section to provide five digital outputs. The condition of the outputs are controlled by a Digital Output Command in the DSA3200 software. -
Page 13: Digital I/O Connections
Digital I/O Connections The DSA3217 - Digital Output Module has a maximum of five(5) Digital Outputs. The Digital Outputs are powered directly by the DC input voltage input. It is recommended that the user supply be capable of providing sufficient current drive for the DSA3217 and the Digital Outputs. Each Digital Output requires approximately 500 mA @ 24 Vdc. -
Page 14: Dsa3217 - Individual Reference Module
DSA3217 - Individual Reference Module The DSA3217 - Individual Reference Module is another special version of the DSA3217. It incorporates a reference tube for each input. The reference inputs are not “valved”, that is, these inputs are not switched during transitions of the control valves. The control valve logic is identical to a standard DSA3217. -
Page 15: Power Requirements Dsa3017/3217/3018/3218
POWER REQUIREMENTS DSA3017/3217/3018/3218 The DSA3017/3217 requires 28±8Vdc at approximately 8 W. This will remain constant while the module is operating normally. The DSA3018/3218 requires 28±8Vdc at approximately 8 W. The power requirements for these modules increase to 28±8Vdc at approximately 35 W if the optional heater is installed. The power requirements will drop when the module reaches the normal operating temperature. -
Page 16: External Trigger Requirements
EXTERNAL TRIGGER REQUIREMENTS The Digital Sensor Array scan functions may be synchronized with other data acquisition devices by using the external trigger. DSA 3017/3018 Modules The 3000 Series Modules may be triggered by a hardware trigger. The external trigger input is optically isolated to prevent grounding problems. -
Page 17: Rs 232 Communications
RS 232 COMMUNICATIONS Every DSA3200 Series Module has an RS 232 output. It is available at the Serial Communications/Trigger Connector. It is designed to be used to configure the module, upload coefficients and operating system upgrades, and provide emergency communications. The wiring of the RS 232 output is shown in figure 10. NOTE: The cable wiring must connect the Tx output from the host computer to the Rx input of the DSA module. -
Page 18: Ethernet Connections
A straight through cable must be used if the module is connected to a hub. Crossover connections are used if the module is connected directly to the host computer. It is recommended that shielded Category 5 cable be used for 10Base-T cables. Figure 10 - DSA 3000 Series 10Base-T cables... -
Page 19: Control Valves
CONTROL VALVES The Digital Sensor Array does not require control pressures for normal operation. It does require control pressures if a multipoint or quick zero calibration is to be performed. Truth tables are different for each module type. Standard Modules Pneumatic Inputs Pneumatic inputs consist of: 16 - Px Inputs, Control Pressure Inputs, and Calibration/Reference Inputs. -
Page 20: Quick Zero Calibrations
Figure 12. The operation of the Quick Zero Calibration is described in the Special Procedures section on pages 34 and 35 of this manual. Scanivalve Corp recommends that a Quick Zero Calibration (CALZ) is performed daily, any time the temperature of the module varies more than 3°C or before any test is performed. -
Page 21: Absolute Modules
Pneumatic inputs consist of: 16 - Px Inputs, Control Pressure Inputs, and Calibration Inputs. All DSA 3017/3217 Px inputs are .063 inch bulged tubulations. These tubulations are designed to accept any .063 inch tubing manufactured by Scanivalve Corp. DSA 3018/3218 Px inputs are 1/8 inch Swagelok fittings. -
Page 22: Quick Baro Calibration
Quick Baro Calibration The Quick Zero Calibration cannot be performed on an absolute DSA module. Using CALZ command will move the zero to barometric (14.7 psia typical). In order to zero an absolute DSA module, a CALB command (performs a baro zero) to make the minor corrections that may be necessary to maintain the Digital Sensor Array accuracy. -
Page 23: Isolate-Purge Valves
Isolate-Purge Mode Procedure Set the internal valve to the Calibrate mode . Set the Calibrator(s) to the Zero Mode. If Scanivalve Corp Calibrator modules are being used, Steps 1 and 2 can be implemented by setting the Calibrator module(s) to the Cal Zero mode using the CALZ command. -
Page 24: Pneumatic Interface Panels
PNEUMATIC INTERFACE PANELS DSA 3017 The DSA 3017/3217 modules use a pneumatic interface panel to connect the pressure inputs to the module. This panel acts as a splash plate to protect the module from liquids. The plates are fitted with 1/16 inch tubulations for the Px and control inputs. Figure 16 shows the panels used on the DSA 3017 modules. -

Page 28: Splash Plate Removal And Re-Installation
Splash Plate Removal and Re-Installation DSA 3017/3217 modules are furnished with a splash plate to protect the module from moisture. The splash plate has a formed gasket on the bottom side which seals the edges of the top of the module. -
Page 29: Maintenance
The calibration valves are included so a customer can perform a calibration or a data validity check. The valves do not require any special maintenance by a user. They should not be disassembled by a user that has not completed training at the Scanivalve Factory. -

Page 38: Dsa 3017/3217 Pneumatic Jumpering For "Quick Zero
DSA 3017/3217 Pneumatic Jumpering for “QUICK ZERO” The DSA 3017/3217 series modules permit the use of the “quick zero” function even if the module is being used in a stand alone mode. This is made possible by connecting CTL1, CTL2, and RTN. This pneumatic jumper permits a quick zero without applying external control pressure logic. -

Page 40: Dsa 3018/3218 Operations For Freon Applications
DSA 3018/3218 Operations for Freon Applications When using DSA 3018/3218 modules in Freon Applications special considerations must be taken. In order to prevent premature deformation of the seals within the DSA 3018/3218's valve, it is important to leave the module in the following ‘dormant’ state. •... -
Page 41: Network Configuration
NETWORK CONFIGURATION The DSA may be configured in three basic network arrangements: - Isolated - Integrated - Sub-network with gateway Isolated Network The isolated DSA network provides the fastest possible data throughput because other network traffic has been eliminated. DSA commands are issued from the network client/host and data is directed to the network client/host in UDP format. -
Page 42: Client/Host Options
PC-OPC Server Scanivalve Corp. has written a OPC Server driver to interface a PC running in an OPC environment to a DSA module. This program is designed to operate in Windows 2000 or Windows XP. PC-Windows HyperTerminal HyperTerminal is a Windows program. -
Page 43: Dsa Network Addressing
DSA NETWORK ADDRESSING Each DSA module has the capability to accept commands in Unicast (only one DSA accepts command) Each DSA module has a unique, factory set, 48 bit physical Ethernet address. When running TCP/IP protocol the DSA modules support ARP (address resolution protocol) to enable the client/host to determine the relationship between the IP address and the Ethernet address.
