SPECIFICATIONS (Typical @ 25C and rated supply voltage unless otherwise specified) STANDARD INPUTS * 4-20ma 0-50ma 0-5Vdc 0-10Vdc * Thermocouple inputs: J, K, T, E, R, S, and B * Cold junction compensation error: +/- 1C (10C to 40C) * Open input indication: HELP displayed * Temperature displayable in Degrees C or F * Non-standard inputs available --- consult factory. - Page 5 NOTE DPS3304 & DPS3314 are four channel units. Therefore, any reference to channel numbers with respect to these models is for channels 1 through 4 only. DPS3307 and DPS3317 are seven channel units, and therefore, any reference to channel numbers for these models is for channels 1 through 7. DPS3304 &...

Page 7: Table 1. How To Display Parameters
DISPLAYING PARAMETERS DPS3300 Series keeps track of various parameters and these may be displayed by pushing appropriate keys on the front panel. The parameters that are tracked are: a) Channel's high peak b) Channel's low peak c) Elapsed time c) Channel with the highest reading Table 1 explains how to display the above mentioned parameters. -
Page 8: Table 2. Display Modes
DISPLAY MODES DPS3300 Series has multiple display modes and can be programmed to either scan, display the channel with the highest reading, display the channel with the lowest reading, deviation between channel's process variable and a pre-programmed setpoint, difference between any two selected channels or just run as a timer. In the timer mode the unit keeps track of process run time with crystal controlled accuracy. -
Page 9: Scan Mode
Scan Mode When setup for scan mode, individual channels are displayed for a programmed period of time. At the end of that time period the, display automatically switches to the next channel. For ease of reading, the display first shows the channel number (Format: 'CHANEL 1') and then the process variable along with the programmed three digit engineering units e.g. -
Page 10: Deviation Mode
In deviation display mode, DPS3300 Series will show the differential between a pre-programmed setpoint and process variable being monitored on each channel by the scanner. Individual setpoint for each channel is programmed during CH Setup and can be any value over the range of selected scale or thermocouple being used. -
Page 11: Sys' Parameter List
To get into SETUP mode, push the SETUP key twice. The first push displays elapsed time and the second push brings the unit into the SETUP mode. SETUP mode is indicated by 'SETUP' in the display window (the SETUP LED indicator will also be illuminated) followed by 'ENtR PC' (for ENteR PassCode). -
Page 12: Channel Configuration
NOTE: To exit from any point during SETUP procedure or to save the newly made changes, simply press and hold the RESET key until the display shows 'SAVING'. When the display shows 'SAVING', it is indicating that the unchanged and the newly made changes are being saved in the EEPROM for permanent storage. -
Page 13: Setup For High Scale
Setup For High Scale After setting a channel's decimal point position, the next parameter to be set is Hi Scale. This parameter determines what number will be displayed when the transducer puts out its maximum signal. For example, suppose a pressure transducer produces a 0Vdc to 10Vdc signal which corresponds to 0psi to 150psi. -
Page 14: Setup For Setpoint
For High Scale) to set the desired TARE number. Once the desired TARE value is displayed, push SETUP key to enter that value and go to setup Setpoint. Setup For Setpoint After setting a channel's TARE, the next parameter to be set is channel's SETPOINT. -
Page 15: Setup For Engineering Units
When this parameter is set for "Normally Open", the relay is open when it is deactivated (readings are below LIMIT), and closes when the channel reading exceeds its LIMIT value. When this parameter is set for "Normally Closed", the relay is closed when it is deactivated (readings are below LIMIT), and open when channel reading exceeds LIMIT value. -
Page 16: Table 3. Display Options
Setup Examples Example #1: Use of the OFFSET Parameter Setup for a 4-20ma transducer signal corresponding to 0-500 gallons of fluid (reading in 10th of a gallon resolution): DECIMAL POINT HIGH SCALE LOW SCALE OFFSET TARE Example #2: Use of the LOW SCALE Parameter Setup for a 4-20ma transducer signal corresponding to 500-2000 degrees Fahrenheit temperature i.e. -
Page 17: Setup For Display Time
The channel numbers in Display Option #6 start with 'CH1 dIF' and go up to 'CH7 dIF' (CH4 dIF for 4 channel units). Following this the display jumps back to Option #1 (elapsed time), and the cycle is repeated. Setup For Display Time The next parameter to be set is DISPLAY TIME. -
Page 18: Setup For Channel Calibration
Setup For Channel Calibration After setting the Cold Junction Reference temperature, the next step is a display of channels for calibration purposes. This allows easy calibration of each channel without the instrument scanning to the next channel. The display will show the channel input reading in the form 'x-nnnnn' where x=channel # and nnnnn is the channel reading. -

3. Adjust the gain pot of the instrument until the display reads '1100'. 4. Short channel #1's input with a wire or shorting bar. 5. Push DIFF key. The display will read '0002' --- or some other value. 6. Adjust offset pot of instrument until the display reads '0000'. 7. -

Once the desired channel has been selected, push 'HI/LO' key. Pushing it once will show the high peak attained by the selected channel. Pushing it a second time will indicate the low process value (NOTE: The second push, to display valley, must be initiated before the display reverts to normal display mode). - Page 21 DPS3317 7 Channel Unit ‘SYS’ Flashing DISPLAY OPTION (Select one) ELAPSED TIME SCAN HIGH CHANNEL LOW CHANNEL DISPLAY DEVN.

Page 23: Figure 1. Open Collector Hookup Example
RATE DPS3300 series tracks the rate of process change/minute for each channel. This rate is displayed by first pushing the CH. SEL key to select the channel whose rate is desired. Once the channel has been selected, push DATA key. The display will briefly read 'cx-rate' (x=channel #), and then the monitored rate for that channel. -

NOTE: LOOK UNDER SPECIFICATIONS FOR THE RATING ON RELAYS AND OPEN COLLECTOR OUTPUTS. UNDER NO CONDITION SHOULD THE RELAYS AND OPEN COLLECTOR OUTPUTS BE OPERATED BEYOND THEIR RATED CAPACITY. DOING SO CAN DAMAGE THE UNIT PERMANENTLY. The status of the relays for all the channels is indicated on the front panel by a row of LEDs. Whenever the relay is energized, its respective LED is turned on. -
Page 25: Table 4. Dps3300 Series Output Connector Pin Assignments
POWER Power connection should be made to the three terminal connector as shown in figure 3. Also, make note that it is very important that the power line inputs and the power ground are not switched. Doing so will permanently damage the instrument. -
Page 26: Direct Interface To Universal Relay Module
DIRECT INTERFACE TO UNIVERSAL RELAY MODULE A special feature in the DPS3300 series units allows direct interfacing with Universal Relay Module (Model RELAY- URM400/800) – via a serial interface. The serial interface is available at a separate connector (as shown) in the terminal compartment. -
