
: ( Outsi de) The output gets switched on, when
the displayed physical value isn’t between the low limit
value (L.LI) and the high limit value (H.LI).
•


( Warm ) The output gets switched on, when the
displayed physical value is lower than the low limit value
(L.LI), When the displayed current value is higher or equal
than L.LI, than the state of output doesn’t change.
The output gets switched off when the displayed current
value is higher than the upper limit value (H.LI). When the
displayed current value is lower or equal than H.LI, than the
state of limit output doesn’t change.
This operating mode is used in other DATCON instruments.
Here you can use it at any control task where the AC
current is the process value and you can control the
process through the limit outputs.


( Cool ) The output gets switched on, when the
displayed physical value is higher than the high limit value
(H.LI). When the displayed current value is lower or equal
than H.LI, than the state of limit output doesn’t change.
The output gets switched off when the displayed current
value is lower than the lower limit value (L.LI). When the
displayed current value is lower or equal than L.LI, than the
state of limit output doesn’t change.
This operating mode is used in other DATCON instruments.
Here you can use it at any control task where the
temperature is the process value and you can control the
process through the limit outputs.


: ( On = switched on) The output is switched on
independently from the measured value.
Exit from the operating
mode menu item 6. After selecting the limit output mode press MENU button
you will see:
