1 Product overview
The Rosemount™ 936 WinHost is communication software for the Rosemount 936
detector. The program displays information (such as status, gain, address, signals, and
LEL) and makes it possible to change the detector’s configuration.
1.1 Software overview
The Rosemount 936 WinHost software makes it possible to:
• Communicate with Rosemount 936 gas detectors
• Read status and parameters from the detector
• Record relevant detector data to a log file (S/N.txt)
• Calibrate the detector
1.2 Minimal requirements
Following requirements are the minimum for operating this software:
• Pentium® 3 GHz
• Windows XP,7,8, or 10
• 2 GB of RAM
• 10 GB hard disk free space
• Isolated RS-485 Interface Card to be defined as COM1, COM2, COM3, or COM4; or
RS-232/RS-485 converter to connect to standard COM port
1.3 Standard

When you start logging, set the log file period in seconds. A line is subsequently written to
the log whenever that number of seconds passes (for example, every 60 seconds) and
whenever there is a change in the detector's status.
Each line in the log notes the following information:
• Detector temperature
• Detector gain
• Detector status
• Date and time
• Detector data
The filename of the recording is the serial number of the device, followed by .txt suffix. The
default location where the file is saved: C:\Users\Username\AppData\Local\VirtualStore

Procedure
1. 1 From the main window, click File → Start Logging .
The log record dialog box appears:
2. In the text field, enter the log file period (in seconds).
3. Click OK.
Logging begins. A line is written to the log (S/N.txt) every time the log file period is
over and any time there is a change in the detector’s status.

5 Maintaining detector
The Rosemount 936 system requires only simple periodic maintenance to provide
satisfactory service and achieve maximum performance.
Use standard tools and equipment to maintain the detector and source. Recording the
periodic test results in the Maintenance log is recommended.
To maintain your detector
• Clean the optical surfaces of the detector and source once a month.
• Perform alignment and calibration once every six months or after each time the units
are moved or opened.
To clean the optical surfaces:
Procedure
1. Turn off the detector.
2. In places where dust or dirt have accumulated on the optical surface, clean the
surface with a small soft bristle brush.
3. Wash the surfaces thoroughly with water and a mild non-abrasive detergent.
4. Thoroughly rinse the glass surface with clean water, ensuring no residue is left
behind.
5. Dry the glass with a clean dry soft cloth.
6. Enter the following information into the Maintenance log: date and name of person
and company who performed the maintenance service.
Postrequisites
Turn on the detector.
Postrequisites
Perform zero calibration.
