Temperature Monitor description
The Temperature Monitor provides added surveillance to existing or new construction/machines
(e.g. wind turbines) where critical parts need to be monitored (e.g. bearings or cooling liquid).
Due to the magnets on the backside of the module, the Temperature Monitor can easily be
mounted anywhere on a metal (iron) surface. All connections are done through prefabricated
cables with moulded plugs to ensure a reliable and water tight connection (IP67).
The PT100 sensors are delivered with 3 or 5 meter silicone cable (standard), complete with
moulded M12 connector. Other cable length can be delivered on request.
The Temperature Monitor is as standard delivered as a kit where all basic parts needed for
installation is included. As standard two temperature sensors are included, if needed more
sensors can be purchased separately.
The Temperature Monitor is powered by 24VDC from the control system (e.g. from topbox or panel).
Internally the system is galvanic isolated to prevent electrical surges (e.g. from lightning strike)
from entering the control system.
The signals to the control system (alarm and warning) are provided by galvanic isolated relay
contacts (dry contacts). The signals and the power supply share the same cable to the topbox.
The alarm output is wired to the external stop input of the turbine controller, using extra wires in the
cable from topbox to CPU panel. If other equipment is connected to the external stop input, the relay
contact from the Temperature Monitor can be connected in series. The relay contacts are Normally
Closed.
Function
The Temperature Monitor has four temperature sensor inputs. A Warning level and an Alarm level
can be set for each sensor. Furthermore a specific function can be selected for each sensor.
Temperature HIGH – Trips when the temperature rises ABOVE the trip level.
Temperature LOW - Trips when the temperature falls BELOW the trip level.
Temperature WINDOW – Trips when the temperature moves OUTSIDE the window (Trip high or
low).
Disabled – No sensor attached (Not in use).
The functions can be selected individually for Alarm and Warning for each sensor.
Three examples are given for the working mode of the Alarm and Warning settings; The LOW trip,
the HIGH trip and the Window functions. Study these three examples to gather knowledge of the
functionality of the relay outputs.
First example: ALARM is set to ‘Temp HIGH’ – triggers an alarm if the temperature increases above a
certain level.
WARNING is set to ‘Temp WINDOW’ – triggers a warning if the temperature moves outside the
window limits.
In the following paragraphs, the term ‘not defined state’ is used in the description of the Alarm and
Warning RESET level. To achieve this, it is necessary to adjust the level setting of the function to the
max. (190C) or min. (-40C) value. Then roll the value to the next step (the value between -40 and
190), and the display will show ‘---‘. This is the setting for ‘not defined’.

When the temperature rises above the Alarm or Warning ‘TRIP’ level, the relay contact opens (in
order to make it fail safe). The corresponding LED will also be lit, indicating the relay ‘open position’.
If an Alarm or Warning ‘RESET’ level is defined, the relay contact closes when the temperature falls
below the ‘RESET’ level (auto reset). The corresponding LED switches off.
Left: RESET level defined. Right: No RESET level defined – here the Reset key needs to be pressed.
For each input it is possible to have both an Alarm and a Warning level. In the below graph the
Warning RESET is defined and the Alarm RESET level is not defined – this means that if the Alarm
levels is reached, it is necessary for the service crew to reset the Temperature Monitor manually. If
the warning level is reached the warning relay opens, and it closes again if the temperature falls
below the RESET level (auto reset).
The Alarm and Warning levels can be set in the range from -40..+190 C.
When set above or below, the limit (trip or reset) is not active and the display shows ‘---‘.
In the ‘TEST / CONFIG’ menu it is possible to force the outputs relays ‘OPEN’ or ‘CLOSED’ individually
in order to test the connection to the control system.
The relays will restore to their current positions according to the relevant measurements and
settings when the menu is left.

Then the settings of the levels can be made:
Mode of operation
When the temperature level rises above HIGH TRIP OR if it falls below the LOW TRIP setting, the
Alarm or Warning relay contact opens (in order to make it fail safe). The corresponding LED will also
be lit, indicating the relay ‘open position’.
If an Alarm or Warning ‘RESET’ (HIGH/LOW) level is defined, the relay contact closes when the
temperature moves within the two ‘RESET’ levels (auto reset), and the corresponding LED switches
off. It is possible to have only one reset level, and one disabled. e.g. auto reset on low trip and
manual reset on high trip.
Left: RESET level defined. Right no RESET level defined – The Reset key needs to be pressed.
To have the RESET level not defined, select the value between -40°C and 190°C in the “Warn.
RESET” level field.
For each input it is possible to have both an Alarm and a Warning level. In the below graph the
Warning RESET HIGH/LOW and Alarm RESET low levels are defined. Alarm RESET HIGH is not
defined – this means that if the Alarm HIGH level is reached, the service crew needs to reset the
Temperature Monitor manually. However, if alarm LOW is reached, it will auto reset in the same way
as if the warning level is reached, the warning relay is opened, and it closes again if the temperature
moves within the RESET levels (auto reset).
NOTE: In this example WARNING TRIP LOW and ALARM RESET LOW are set to the same
temperature.
Sensor fault function behavior
For each sensor, it is possible to determine how the output should react in case of a faulty
sensor (shorted or open circuit is defined as sensor fault). When a temperature sensor is
disconnected, or if a sensor wire breaks, the display value will show ‘---‘ as an error indication
for the current temperature sensor. If a faultless sensor is reconnected, either by itself (e.g. a
periodic broken wire) or manually, the display value will flash between '---' and the measured
temperature until the ‘Reset’ button is pressed. This indicates that the sensor has been faulty,
but has recovered. The below list shows the possible settings for the sensor fault function:
NO
ACTION
No reaction in case of sensor fault. Select this if no sensor is
connected.
ALARM/Man.RESET
Alarm relay is opened in case of sensor fault – manual reset
acquired (Press RESET).
WARN./Man.RESET
Warning relay is opened in case of sensor fault – manual reset
acquired (Press RESET).
AL+WR/Man.RESET
Alarm and Warning relay is opened in case of sensor fault – manual
reset acquired (Press RESET).
ALARM/AutoRESET
Alarm relay is opened in case of sensor fault – Resets automatically
when the fault is removed/repaired.
WARN./AutoRESET
Warning relay is opened in case of sensor fault – Resets
automatically when the fault is removed/repaired.
AL+WR/AutoRESET
Alarm and Warning relay is opened in case of sensor fault – Resets
automatically when the fault is removed/repaired.
The two relay contacts are common for all Alarm/Warning levels functions. This means that one
or more alarm/warnings are able to open the relay contact. In case of trip or fault, the ‘normal’
display window will show an “A” or “!” sign to the right for the sensor number. This indicates
that the actual sensor / function is causing an alarm or warning. In case of both alarm AND
warning the display changes between “A” (Alarm) and "!" (Warning).
Two LEDs on the front indicate the status of the alarm and warning relay. If lit = contact open.
Temperature data
The Temperature Monitor updates the actual temperature measurement approx. every second.
The highest measured temperature is stored as ‘MAX’ and the lowest as ‘MIN’. At the same
time an average temperature is calculated and is stored as ‘AVG’. MIN, MAX and AVG can be
readout and, if decided, the values can be reset individually (manually).
Every 5 minutes all three actual temperatures are stored in the internal memory (data logger).
The memory contains 4 x 32767 values which are all temperatures, approx. 2730 hours back in
time (equal to approx.114 days).The data can be extracted using the RS485 interface. The
RS485 interface is intended for future connection to e.g. SCADA systems. For further
information about the port, please contact us.
Menu system
The Menu structure of the Temperature Monitor is made as a tree structure. The four keys on the
front is used to navigate, and in some cases also used to adjust values.
