AC mains connection to the power supply The VistaShield Stir/Purge does not connect directly to an AC mains supply. Instead, the mains is connected to the desktop AC-adapter, which outputs 12 V DC, which in turn powers the Stir/Purge.
Chapter 1: Safety Considerations - Grounding in the VistaShield and Stir/Purge The VistaShield Stir/Purge is normally provided with an AC line cord suitable for your location. This AC line cord connects the AC mains to the AC power adapter. If your VistaShield has been provided without an AC line cord, or a cord that is not compatible with your local AC mains socket, obtain a line cord certified for use in your country.

Chapter 3: Unpacking and Installation – Complete Unit This chapter of the Gamry Instruments Inc. VistaShield Stir/Purge Operator’s Manual covers normal installation of the Stir/Purge when purchased with a VistaShield. When this is the case, the Stir/Purge has already been mounted under the VistaShield.
After you remove your VistaShield with Stir/Purge from its shipping carton, check it for any signs of shipping damage. If any damage is noted, please notify Gamry Instruments, Inc. and the shipping carrier immediately. Save the shipping container for possible inspection by the carrier.
Power cord and power connection The VistaShield Stir/Purge does not plug directly in the AC mains supply. Instead, the mains is connected to an external power supply, which supplies a regulated 12-volt DC output. This regulated DC is then connected to the POWER IN jack on the rear of the Stir/Purge.
LED indicators is not important at this time. Caution: If the POWER LED goes on, then turns off and stays off, the Stir/Purge is not working properly! Contact Gamry Instruments or your local Gamry Instruments representative as soon as possible if this power-up test fails.
Chapter 3: Unpacking and Installation – Complete Unit--Gas fitting installation Gas fitting installation Three purge gas ports exit the Stir/Purge from the rear of the unit. One is used as the gas inlet and two are used as gas outlets. All three ports are designed to accept 1/8” NPT male fittings. The hose barbs normally used in these ports protrude significantly from the case, which can make them susceptible to damage during shipping and unpacking.
Unpacking When you receive your Stir/Purge option, please verify that you have received the following items: Stir/Purge unit Stir/Purge Operators manual Gamry Software installation CD-ROM AC Line cord 12 V output desktop power supply Quick-disconnect 1/8” NPT Quick-disconnect with shut-off Qty 2 of 1/8”...
Chapter 4: Adding a Stir/Purge to a VistaShield and Stand-Alone Operation--Installation of the Stir/Purge as a stand-alone system 3. Fix the VistaShield to the Stir/Purge, using four flat-head screws supplied in Stir/Purge Configuration Kit packet, as shown: 4. The installation of the Stir/Purge option onto the VistaShield is now complete. Continue the system installation using the information in Chapter 3.
Disassembly of the Stir/Purge from the VistaShield Circumstances may require removal of a Stir/Purge option from a VistaShield. If the Stir/Purge is in need of service, it should be returned to Gamry separately. Follow these step-by-step instructions to disassemble the system.

The LED above the toggle switch is lit whenever the gas flow is directed to PURGE, whether manually via the toggle or through software when the switch is set to REMOTE. The default behavior with the Gamry Framework software is that blanket gas flows before, during, and after an experiment. The purge gas flows only when performing the stir/purge operation.
POWER IN jack POWER IN jack The VistaShield Stir/Purge derives power from +12 volts DC input through the POWER IN jack. The input current is less than 500 mA. Caution: Use of an incorrect power source can damage the Stir/Purge’s power supply, and/or reduce function.
The Digital I/O is a compact 15-pin D female connector that is fully isolated from the Stir/Purge Chassis. A cable for connecting the Digital I/O to a Gamry Potentiostat is included. If you purchase a 3 party cable, ensure that the cable has all 15 pins connected.
USB connectors are both isolated so that the Stir/Purge is not in ground contact when either is connected. Proper use of the VistaShield Stir/Purge and Faraday Cage has the ground post inside the Faraday cage connected to the ground reference of the potentiostat. If this ground reference is also an earth ground then the system will be earth-grounded.
The USB port on the Rear panel of the Stir/Purge is only used for updates to the Stir/Purge firmware. This should be required infrequently, if required at all. Gamry Instruments recommends that you update your Stir/Purge firmware only when a Gamry representative tells you that an update is needed.
