TEMPERATURE MONITORING UNIT DTI AND EDTI
Visualization of the maximum measured temperature
Pressing the Tmax key on displays, it will appear - in flashing mode - the maximum
measured value of temperature.
To pass from the visualization of the maximum temperature T1-T3 to T2-T4 to use
← and → keys.
After 8 seconds the device come back to display the value of measured temperatures.
To reset the value of the maximum temperatures, go in the visualization maximum
values and press at the same time Tmax and ←.
Visualization of the channels with the higher temperature
Pressing the HOT key for some seconds till switching to the HOT led.
On the T1-T2 display, the hotter temperature among the inputs 1 and 2 will
appear.
On the T3-T4 display, the hotter temperature among the inputs 3 and 4 will
appear.
To come back in the standard visualization mode, press the HOT key for some
second up to switch-off the relative signalling led.
Test of the light signaling
Press at the same time ← and → keys: all the signalling lights will start to flash
for some seconds.
Exclusion of the input probes not used
If one or more inputs are not used, it's necessary to connect a resistance of value
included between 100 and 200 Ω, or 0.25W.
The input 4 can be disables through the "Selection number of active inputs" on
page 5.
In the figure is showed the connection to disable the input Ch1.
The same connection can be used for the other inputs.
