OM-60-TE SERVICE LOGGER

WITH

TEMPERATURE/EVENT ADAPTER

The OM-60-TE is a Service Logger with a temperature/event adapter. The field
inter-changeable temperature sensor and the event adapter are available as part
# OM-60-MOD-TE. The OM-60-MOD-TE option consists of a temp erat u re
sensor, an interface box with a built in voltage detector and a cable which
connects to the Service Logger. The OM-60-TE allows for independent tem­perature measurement and voltage detection. This is commonly described as
event detection.

The temperature sensor is enclosed with a 4 inch long stainless steel jacket
which may be immersed in any solid or liquid and is compatible with type 300
series stainless steel. Refer to the product specifications for the environmental
limits of the temperature sensors. The TP series temperature sensors are inter­changeable and replacement sensors are available. Each temperature sensor
has 6 feet of cable.

Immersion of the entire sensor body and cable, and/ or c utting or
splicing of the OM-60-MOD-TE cables by the user is not
recommended and will void the se ns or warranty.

The voltage detector is connected by tw o co i l ed cli p leads available at the
interface box. The voltage detector will operate on any voltage source in the
range of 24 VAC to 270 VAC or 24 VDC to 180 VDC. Note that exceedin g th e
voltage range of the voltage detector can cause permanent damage to the
adapter.

CAUTION!

Electrical connection to any type of operating equipment is dangerous. The
voltage detector leads s h ould only be connected when it has be e n determined
that the power is off and the equipment is safe to touch!

GETTING STARTED

Connect the interface cable from the interface unit to the Service Logger. Plug
the temperature sensor into the interface unit. Note that the interface box is
labeled to indicate where the temperature sensor connects to. The clip leads are
permanently attached to the interface box. Make sure the equipment power is

OFF before connecting the leads!

If portable use or battery backup is desired, place a fresh 9V alkaline battery
into the Service Logger. Any other type of battery will result in unsatisfactory
performance and may cause damage to the instrument. Plug in the power
adapter if a 110 (220) Volt outlet is accessible.

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 an interface unit is plugged in and auto­matically set up the correct menus and displays
for that interface.

This is the Operating Mode display for the
OM-60-MOD-TE Sensor. The temperature of the
sensor and the presence of voltage at the
detector leads are continuously measured and
displayed. This is the mode the Service Logger
will go to after it is turned on.

If the temperature sensor is not connected or
has become defective, the display will indicate
that the sensor is not responding.

Temperature sensor is not responding.

CHANGING SETTINGS

Every function of the Service Logger can be set through a series of menus.
Settings are stored in memory and remain there even without the main and
backup power source until altered by the user. Each sensor will have settings
unique to its function and the Service Logger will select and display the correct
menus for each sensor that is plugged in.

Note that recording on event change is not a time related recording func­tion. The Service Logger will monitor the Event Detector and only make a data

recording when the status of the event detector changes from ON to OFF or
from OFF to ON. There is also a maximum time limit between events. If the
Service Logger does not detect a change in state for more than 45 hours the
Service Logger will assume no events are occurring and the recording will be
automatically terminated. As in the time related recording fu n ctio n s th e d i sp lay
will continuously show the status of the temperature sensor and event detector
but will only record data on a change in the state o f the even t d etecto r.

When the

RECORDING DATA

One of the most important functions of the Service Logger i s to reco rd
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 information, tran sfer th e in f or mati on to a
computer for advanced analysis or long term storage, or review the information
on the Service Logger’s display.

In the case of the OM-60-MOD-TE sensor, the temperature and presence or
absence of voltage 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 of data. It is the
option of the user to record data to the maxi mu m cap a ci ty o f th e Servi ce Log g er
or to terminate a recording when sufficient i n fo r matio n h a s b een g ath ered .

IMPORTANT !
Each new recording will erase any previously recorded information. It is the
responsibility of the user to either print 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 presence or absence of voltage will be measured
and stored into digital memory. No record of information is made between each
sample even though the display will continuously show the environment the
OM-60-MOD-TE sensors are exposed to.

If the Service Logger is set to record on event change, then only when the state
of the voltage detector goes from ON to OFF or from OFF to ON will a data
recording be stored in memory.

For a recording to accurately reflect a series of events, it is up to the u ser to
select a recording interval that best suits the particular application. In some
situations maximum recording time may be sacrificed so that more frequent
sampling may be accomplished. Long term monitoring will require less frequent
sampling in favor of longer recording times. The record on event change will
usually be used when the data of interest occurs only under a specific
condition.

The next step is to select how the Service Logger will record the information
from the OM-60-MOD-TE sensor. There are 3 possible ways to record
information.
