OM-60-TP SERVICE LOGGER

WITH

The OM-60-TP is a Service Logger with a temperature sensor and a pressure sensor. The sensors are field interchangeable and are available as part # OM60-MOD-TP. The OM-60-MOD-TP option consists of a temperature sensor, pressure sensor, an interface box and a cable which connects to the Service Logger. The OM-60-TP allows for independent temperature and pressure measurements.

The temperature sensor is enclosed with a 4 inch stainless steel jacket which may be immersed in any solid o r li q u i d a n d i s co mp a ti b le w i th 300 seri es stainless steel. Refer to the product specifications for the environmental limits of the temperature sensor. The TP Series temperature sensors are interchangeable and replacement sensors are available. The supplied temperature sensor has a 6 foot long cable. The pressure sensor is permanently connected to the interface box with a 6 foot ca b le. Th e ma xi mu m mea su red pressure is 500 PSI (35 Bar). The pressure sensor is compatible with any gas or liquid that is compatible with 17-4 stainless steel and is well suited for HVAC applications.

GETTING STARTED

TEMPERATURE/PRESSURE SENSOR

Cutting or splicing of the OM-60-MOD-TP cable by the user is not recommended and will void th e s ensor warranty.

Plug the interface cable into the Service Logger and the interface box. Plug the temperature sensor into the interface box. Note that the interface box is labeled to indicate the temperature sensor connection. If portable use or battery backup is desired, place a fresh 9V alkaline battery into the unit. Any other type of battery will result in unsatisfactory performance and may cause damage to the instrument. Plug in the power a d a p ter if a 110 (220) Vo lt o u tlet i s accessi b le.

Press the "ON" button on the front panel. The display will show the instrument name. If no display is visible, or if the display is all black, adjust the display control until the lettering is visible.

If no adapter is connected, or if the adapter has become defective the display will show this message. The Service Logger will recognize when a sensor is plugged in and automatically set up the correct menus and displays for that sensor. If the temperature sensor is not connected or has become defective, the display will indicate that the sensor is not responding.

RECORDING DATA

One of the most important functions of the Service Logger is to record information over a period of time. This function is like a chart recorder except that the information is stored in memory rather than being printed on paper. The user can choose to print the informati o n, transfer the information to a computer fo r advanced analysis or long term storage, or review the information on the Service Logger’s display.

In the case of the OM-60-MOD-TP option, the temperature and pressure will be recorded. Different sensors will, of course, record different information depending on the function of that sensor. The Service Logger has a memory capacity to record up to 4000 samples o f d a ta . It i s th e o p ti o n o f th e u ser to reco rd data to the maximum capacity of the Service Logg er o r to termi n ate a reco rd i n g when sufficient information has been gathered.

IMPORTANT ! Each new recording will erase any previously recorded information. It is th e responsibility of the user to either print out or store a previous recording prior to starting a new recording.

The first step in making a recording is to select the proper recording time and sample rate. If a sampling rate of 15 seconds is being used, then every 15 seconds the temperature and pressure will be measured and stored into digital memory. No record of information is made between each sample even tho ugh the d i splay will continuously show the environment the OM-60-MOD-TP sensors are exposed to.

For a recording to accurately reflect a series of events, it is u p to the u ser to select a recording interval that best suits the particular application. In some situations maximum record i n g time may be sacrificed so tha t more frequent sam-

pling be accomplished. Long term monitoring will require less frequent sampling in favor of longer recording times. The next step is to select how the Service Logger will record the information from the OM-60-MOD-TP sensor. There are 3 possible ways to record information.

Press and hold

RECORD

button until the record display appears. The four re-

cording modes can be scrolled and changed by using buttons:

1. Record information to memory only. This option stores information into the Service Logger’s memory. No printer or computer connection is required for this function.

2. Record information to a printer. This option does not store information into memory, but does print each sample as it is recorded to a printer. This is referred to as REAL TIME PRINTING. A printer must be connected for this function! If no printer is connected, or if the printer is off-line, or if the printer is out of paper an error message will be displayed to alert the user to a problem. Switching to this option will terminate recording if the Service Logger was set to record previously.

3. Record information to memory and to a printer. This is a combination of options 1 and 2. Information is stored in memory and at the same time each sample is recorded to a printer. As in option 2., a printer must be connected and functioning or an error message will be displayed.

As the recording continues this number will decrease. The Service Logger will continue to record until the recording is terminated manually or when all of the available memory has been used. When 0% Memory Left is displayed, this will indicate that almost all of the available memory has been used and the Service Logger will shortly terminate the recordi n g au to mati cally.

PRINTING RECORDED DATA

After a recording has been made the user will probably want some way to view and analyze the recorded information. This is most easily accomplished by printing out the data samples. The printed data can be analyzed or stored fo r future reference. Several print options are available.

Filtering Printed Record

If the user were to print out a recording which used all of the memory capacity of the Service Logger, this woul d b e a very lo n g reco rd o f 4000 d a ta sa mp les. To print this out line by line on a standard computer printer would use over 60 sheets of paper! Obviously this would be a cumbersome and time consuming process. In most cases the information required from the record is only when the temperature or pressure changes. If the temperature or pressure remains constant, it is not necessary to print line after line of the same information.

The Service Logger allows the user to select from 1° to 10° of temperature change or 1 to 10 PSI (0.0 to 1.0 BAR) of pressure change to print on. What this means is that data samples that are less than the selected temperature o r p ressure change are ignored during the printing process and only when the temperature or pressure has changed by the selected amount is a sample printed out. That temperature or pressure becomes the new value to compare to and the temperature or pressure will have to change again by the selected amount before another sample is printed.

One important point to remember is that even if a data sample is not printed the Service Logger still has to recall it from memory and compare it to the filter selection. Therefore, a printout may take up to 10 minutes for a scan of all 4000 data samples. This may sound complicated, but is easy to understand by using an example recording.

Example:

A recording has been made of water temperature and pressure over a 30 hour period. This means that a data sample is recorded every 30 seconds. For the printout the user has selected a change of 2°. Shown below would be a typical printout of the data using the above selections. In a real printout there will be no spaces between the lines of printing, but in our example these were added to allow room for comments to be inserted.

TRANSFERRING DATA TO A COMPUTER

After a recording has been made, the user may download the data to any PC compatible computer. The advantage of doing this is that it allows the use of more sophisticated analysis tools as well as a long term storage. Unlike the Print and View functions no filtering options are available in this mode. The entire recording is sent to the computer. The supplied software will convert the data recording to an ASCII file which can then be imported into a variety of data analysis software, word pro cessin g , a n d d a ta b a se p r o g ra ms. It i s su g g ested th a t i f the user plans to download recorded da ta o n a reg ular b a si s to co p y the tran sfer program to the users hard disk.

To start the transfer program insert the supplied di skette i n d rive A. Typ e “A:SUPCO” and follow the instructions on the computer screen. A README file is also included on the floppy diskette which has detailed instructions on the use of the transfer program and reflects the latest informatio n th at i s no t i ncluded in this manual.

IMPORTANT! To use this function the 25 pin cable (DB25 Male-M ale) must be c onnected to the Service Logger and the PC compatible computer printer port. If you are unsure of which connector is the printer port, c onsult the ow ners manual which was supplied with the computer.

The computer transfer cable can be purchased from OMEGA as part # OMCC6.
