Limit Value 2 Function - Aquametro CALEC energy master Instructions De Montage Et D'utilisation

The units of the output variables correspond to the units of the current values in the submenu
Basic setting / Units. These can be set in programme mode.
Example switching hysteresis (Hyst.)

11.3.7 Limit value 2 function

The limit value 2 function allows monitoring of whether a current value lies between two threshold
values. If the current value leaves or enters the range between the limit values, a signal can be is-
sued. The settable values largely correspond to those of the limit value function. Added to this is an
input for limit value 2:
Output 4

11.3.8 Function 0 – 20 mA
With the 0 – 20 mA function, an analogue signal is issued. With this function, the signal receiver can-
not detect a power cut
Output 7
...
Funct. 0 – 20 mA
Outvar: temp. cold
Status 10.000 mA
0/4 mA 0.0°C
20mA 200.0 °C
I-ErrU 21.5 mA

Limit value Th 80.0 °C, switching hysteresis 2 %:
Make point = 80.0
Break point = (1 – 0.02) * 80°C = 78.4 °C
