Campbell Scientific PVS5120 Portable Samplers Quick Deploy Owner's Manual
Campbell Scientific PVS5120 is a portable water sampler designed for a variety of environmental monitoring applications. With its ability to collect discrete or composite samples, the PVS5120 is ideal for water quality monitoring, stormwater runoff sampling, and industrial wastewater monitoring. The sampler's rugged construction and simple operation make it suitable for use in remote locations or harsh environments.

IMPORTANT NOTE: This Quick Deploy Guide is a general reference guide to give the installer an overview of the steps required to make this system operational. The Owner’s Manual is the definitive source for detailed installation instructions and information.
!
Caution!
• When sampling hydrocarbons, grease, oil, etc., regular cleaning of the metering chamber, volume control tube, liquid detect/conductivity rod, and intake flow tubing is essential for continuous successful sampling.
• Placing the end of the intake tubing directly on sand and gravel beds can result in unrepresentatively high sediment loads being collected. If a strainer is not used, gravel and sand may lodge in and plug the intake tube, metering chamber, and sampler distribution body (discrete sampler only).
• Connecting the battery cables improperly will cause the PVS5120 fuses to blow in order to protect the unit. Replace them with the same rated fuses as the originals. ( 28314- 5A, 28315-10A )
• Before deploying, check all connections, intake tubing, vacuum tubing, and the meter chamber cover for proper tightness and seating to prevent air leakage.
• Exercise proper lifting techniques when lifting this product.
• Damages caused by freezing conditions will not be covered by the warranty.
• When the PVS5120 is being stored for periods of time, disconnect the battery to reduce discharge over time.

Physical Deployment
Refer to Figure 1A.
1. Loosen the brass nut to set the volume control tube to the approximate volume required for collection by aligning the base of the rod with the graduated marking on the metering chamber. It is best to collect this volume at least once to make sure it matches expectations. If necessary, adjust the tube up or down to obtain the desired collection volume.
2. Set the height of the conductivity rod. The bottom of the conductivity rod must be higher in the metering chamber than the volume control tube (at least 1/2”), but below the bottom of the float valve barrier.
3. Connect the positive lead to the top of the conductivity rod (yellow cap).
4. Connect the battery.
• If using an internal battery, place it in the mount and connect the red and black leads to the matching terminals.
• If using an external battery, make sure the external power cable (Fig. 1D) is stripped and the correct leads are in place to connect to the battery.
Connect the external power cable to the front of the sampler (Fig. 2).
• Connect the yellow caps around the fuse.

5. Turn on the sampler and set the 3-way switch on the control panel to the power source being used (Fig. 2). If powered correctly, the green indicator light (Fig. 2) will come on for several seconds, and then start blinking green once per second.
6. Connect the intake hose and tighten the hose clamp.
7. Put the sinker end of the intake hose into the water body to be sampled, ensuring at least 3 inch depth.
8. Run the Autodeploy routine by pushing and holding the manual control button until the sampler begins running (hold the button shown in Figs. 2
Figure 3
Introduction: This guide provides the steps to setup and run in two common deployments: A) time based control (no datalogger needed) and B)SDI-12 control with a datalogger.
and 3 for approximately 5 seconds). The Autodeploy routine will set the purge and vacuum times based on the length of the hose and the change in height between the sampler and the water source. Wait for the sampler to stop before proceeeding to Step 9.
9. Remove the control section of the PVS5120 and empty the sample just collected.
10. Push the Manual Control button ONCE (Figs. 2 and 3). This will “service the sampler” and reset the sample count to 0. Figure 4
11. a. Connect the USB cable (Fig. 1B) to the front of the sampler controller (VSC100) and the other end to the laptop USB port (Fig. 4). Wait for Windows to install the driver before
opening the software. b. Open DevConfig. Select the VSC100 Series under the Sampler option as shown in Figure
5A. Select the Communication Port option and find the correct COM port (Fig. 5B). Click
CONNECT (Fig. 5C) c. Click on the Clock tab at the top. Next click on Set Clock. this will sync the sampler clock with the computer clock.
12. It is now time to configure the rest of the sampler settings. The sampler leaves the factory assuming it will be controlled via SDI-12, have 24 bottles in the base, and collect 1 sample per bottle. All of these general settings can be easily changed. Proceed to Section 3 (Time-Based Control with NO Datalogger
Interaction) or Section 4 (SDI-12 Control with a CR1000 Datalogger), depending on how you want the sampler to operate.

Scenario A:
Time-Based Control With NO Datalogger
It is possible to run the sampler via time based control and still receive status feedback to a datalogger via Modbus or PakBus. Please see the manual for more information regarding this setup.

5. The example CRBasic program available at www.campbellsci.com/pvs5120c demonstrates how to control a sampler via SDI-12 with a CR1000. Many other programs are available at the Campbell Scientific website. There are multiple best management practices for programming the PVS5120. Please refer to the manual for this information.
6. Connect to the datalogger. The following steps assume a knowledge of how to set up a CR1000 and connect via a direct connection or remote connection.
Please see the datalogger manual for more detailed instructions on connecting to a datalogger.
A. From the LoggerNet Connect screen click on Collect Now to collect any data on the datalogger.
B. From the Connect screen, click on the Send button. Browse to find the CRBa-
sic program that controls the PVS5120 via SDI-12. Click Open | Send.
C. Generic SDI-12 information: An M! command needs to be issued to trigger a sample. The address referenced in the command MUST match the SDI-12 address set in DevConfig. The PVS5120 does not support extended SDI-12 commands. Also, an array of 4 variables will need to be created to hold the data returned after the M! command. The values returned are:
1. Sample bottle #
2. Sample number
3. Response code: numeric code between 0-8 (see Table 1).
4. Sampler battery voltage
