DEVICE DESCRIPTION 2
The device is available with a white light source or an infrared light source. There are no visible differences between these versions. Both versions provide the possibility of ultrasonic cleaning. Every device has a pressure regulator for the incoming flow which reduces pressures up to 14 bar / 203 psi down to 1 bar / 15 psi.
Dehumidification system
The device is equipped with a continuous dehumidification system that works with the help of a replaceable desiccant pouch in the electronic device. While the system heat is used to warm the air, a fan inside the device continuously circulates this heated and by the desiccant pouch dehumidified air around the optical well and the electronic device. This features eliminates the need for a dry purge line.
The device monitors the replaceable desiccant pouch condition continuously. The lower line of the display shows the message "DESC" in the event that you have to replace a saturated desiccant pouch that may cause problems.
Liquid crystal display (LCD)
For a better readability in low light or no light conditions the LCD is backlight. The backlight always stays on, but the brightness is adjustable.

2 DEVICE DESCRIPTION
RS 485 interface
In addition to the Modbus communication the device can operate in two other RS 485 modes:
• Online: the device operates as a small SCADA system (Supervisory Control and Data Acquisition) with an optional software package (to get this package contact the manufacturer or your local sales office). This system allows the connection of up to 255 devices for data logging which all have to be an OPTISYS TUR 1050. Furthermore this system offers a direct interface with common database and spreadsheet software.
• Simple: the device can provide basic communications with the help of simple programs. Examples for such programs are Hilgraeve hyperterminal (included in most Microsoft Windows packages) or Visual Basic.
Ultrasonic cleaning
This feature helps to clean the ultrasonic cuvette continuously. The system works by sending an ultrasonic frequency through spring connections in the upper part of the device to a piezo transducer at the bottom of the ultrasonic cuvette. The ultrasonic cleaning can increase the time between cleanings significantly. However it cannot substitute the manual cleaning entirely.

OPTISYS TUR 1050

3.3 Requirements of the device

The device was designed to require very low input pressure. Though the device offers a wide pressure range, as it has an integrated pressure regulator:
• Input pressure range: 0.07...14 bar / 1...200 psi (built in regulator set at 1 bar / 15 psi)
• Maximum allowable flow rate of the cuvette: 0.1...1 l/min / 0.026...0.26 gal/min
• Maximum fluid temperature: +50°C / +122°F

3.4 Installation order

CAUTION!
Installation, assembly, start-up and maintenance may only be performed by appropriately trained personnel. The regional occupational health and safety directives must always be observed.
To install the device in the correct way, follow the order of the following sections and their instructions.

3.4.1 Placing the desiccant pouch and the humidity indicator

CAUTION!
A missing or saturated desiccant pouch affects not only the performance of the whole device, but can also destroy the internal electronics! If the seal at the device base does not fit properly or is defective, the lifetime of the desiccant decreases. Therefore assure the following items:
•
Do not start-up the device with a desiccant pouch missing, replace a saturated pouch!
•
Replace the desiccant pouch when the display shows the message "DESC".
•
Inspect the enclosure seal each time you replace the desiccant.
•
If the seal is not properly seated or damaged, reseat or replace it!
INSTALLATION 3
Execute the following steps to insert or replace the desiccant pouch and the humidity indicator
®
(Humonitor
Figure 3-1: Desiccant pack (desiccant pouch with humidity indicator)
card) or to inspect the seal:
CAUTION!
The desiccant degrades prematurely after removing the protective packaging. Therefore do not open the packaging before usage, install the desiccant pouch quickly and close the device as soon as possible.
• Move the lock ring counterclockwise and pull out the ultrasonic cuvette with flow-through
holder (detailed information on page 21).
• Unscrew the four corner thumbscrews of the electronic device manually according to 1 in the
following drawing (if the screws are too tight, use a screwdriver for slotted grub screws).
• Remove the upper half of the electronic device 2.
• Prior to installing the desiccant pouch for the first time, remove the shipping support (plastic
tube with a red flag reaching outside) within the upper part of the device; after removing you can discard the tube.

3 INSTALLATION
• If you want to replace the desiccant pouch and the humidity indicator, take them out at first 3.
• Take the shrink packed desiccant pouch and the humidity indicator out of the protective
packaging.
• Put the humidity indicator on the bottom of the lower part of the electronic device and lay the
desiccant pouch on it 4 and 5.
• Inspect the seal and reseat or replace it if necessary.
• Reassemble everything in reverse order 6.
• To expedite the recognition of the new desiccant, reset the powered device by disconnecting
the sensor interconnect cable for two seconds and reconnecting it.

3.4.2 Selecting site and mounting

The preferred way of mounting of the device is wall mounting. If this is not possible, you can mount the device on any suitable level surface. Irrespective of this possibilities always note the following guidelines:
• Choose a location that is easily accessible for operation and service and that is as close as possible to the sampling point to ensure a quick response time (maximum distance: 3m/10ft)
• Leave at least 20 cm / 8" of free space above the device for easy service (e.g. removal of the flow head and insertion of calibration cuvettes), see position number 1 in the following drawing.
• Ensure that the front display rests at eye level.
• Refer to chapter "Dimensions" for the device dimensions.
• Use screws M6 / 1/4" to fix the electronic device 2 and M4 / 3/16" to fix the junction box
power assembly 3.
OPTISYS TUR 1050
16
OPTISYS TUR 1050
INFORMATION!
The design of the device recommends that the junction box power assembly cradles in a hutch below the electronic device. Therefore the correct procedure is to fix the junction box power assembly first and then mount the electronic device on top of it.
Mounting procedure
• Take a water-level, a pencil and ruler and use the dimensions in the following drawing to mark
the six mounting hole locations on the mounting surface. Note: Do not use the drawing on the following page directly as mounting template as the printed dimensions there differ from reality!
• Drill six holes into the mounting surface and insert six screw anchors into them.
• Use screws M4 / 3/16" to fix the junction box power assembly at first.
• Put the electronic device on top of the junction box power assembly and use screws M6 / 1/4"
to fix it.
