TEMPERATURE MONITORING UNIT DTI AND EDTI
Visualization of the maximum measured temperature
On the relative channel, if the threshold value set is exceeded of +1°C, after 5 se-
conds the ALARM relay is energized and the ALARM led is. The alarm rearm (relay
de-energized and the involved LED off) occurs when the temperature goes down
of 2°C respect at the threshold value set.
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.
