1. DESCRIPTION
2. APPLICATION
Through serial output, the RS-485 allows communication with SITRAD software, which makes its
configuration simple and fast.
®
The
is a temperature indicator with serial communication. It can work with up to three
sensors. Each sensor input can be configured individually through the advanced function menu, where
the user can enable or disable each sensor and adjust their calibration offset. The functions
and
provide indication for differential and average temperature among the sensors.
Freezers, operating machines, hothouses, stoves, freezing trucks, acclimatized rooms, food/ chemical/
drug industry.

Access Code
An access code is required when you want to change the configuration parameters. Access code is not
required if you just want to view the parameters adjusted.
Sensor 1 ON or OFF
Sensor 2 (ON or OFF)
Sensor 3 (ON or OFF)
Sets the temperature measurement from sensor 1 to ON or OFF. This input can be disabled only when it
is not being used by any other indicator function and at least one other input is ON.
Sets the temperature measurement from sensor 2 to ON or OFF. This input can be disabled only when it
is not being used by any other indicator function and at least one other input is ON.
Sets the temperature measurement from sensor 3 to ON or OFF. This input can be disabled only when it
is not being used by any other indicator function and at least one other input is ON.
Sensor 1 input OFF
Sensor 1 input ON
Sensor 2 input OFF
Sensor 2 input ON

LED display indication setup mode
This function allows you to configure the preference temperature to be displayed. Choose one of the
following:
Displays sensor 1 temperature
Displays sensor 2 temperature
Displays the differential temperature
Displays sensor 3 temperature
Displays the average temperature
Displays all temperatures, sequentially
Differential calculation setup mode
You can configure how the differential temperature calculation is performed.
Differential temperature calculation OFF
Sensor 1 temperature minus sensor 2 temperature
Sensor 1 temperature minus sensor 3 temperature
Sensor 2 temperature minus sensor 3 temperature
Average calculation setup mode
You can configure how the average temperature calculation is performed.
Average temperature calculation OFF
Average temperature between sensor 1 and sensor 2
Average temperature between sensor 1 and sensor 3
Average temperature between sensor 2 and sensor 3
Average temperature among all sensors (1, 2 and 3)
Device address in the RS-485 network
Device address in the network for communicating with SITRAD .
Note: You cannot have two or more devices with the same address in a network.

5. FUNCTIONS WITH EASY ACCESS
5.1 Viewing other temperatures
For scrolling through the many temperatures (sensor 1, sensor 2, sensor 3, differential and average
temperature) press
until your selection is displayed:
Sensor 1 temperature
Sensor 2 temperature
Sensor 3 temperature
Differential temperature
Average temperature
The selected temperature will be displayed for 15 seconds and then returns to the preference
temperature (previously selected in the
function).
Press the
key to view the min./ max. temperatures for each sensor and the min./ max differential
temperature. If you press the
key shortly, the
message is displayed indicating sensor 1
temperature followed by min./ max temperatures. Then sensor 2 temperatures (
) are displayed
followed by sensor 3 (
), differential (
) and average (
) temperatures.
If you hold the
key for a while the values are reset and the
message is displayed.
