M&C EC-30C - mA-output configuration guide

68 EC-30C | 1.00.02 +49 2102 935 888 www.mc-techgroup.com
12.2 How to configure the mA-output
The mA-output value always corresponds to the temperature of the active deep-cooling
unit. That means, that it always represents the current ouptut dew point. T
min
is the lower
temperature limit set in the parameter menu. T
min
is either assigned to 0 mA or 4 mA. T
max
is the upper temperature limit and is assigned to 20 mA.
By changing the temperature limits, the user can adapt the mA signal to the required tem-
perature range ∆T. This way the resolution of the signal can be influenced.
Depending on the temperature limits set by the user, either ∆T
min
or ∆T
max
needs to be de-
terment first.
12.2.1 How to calculate temperature based on measured mA-value
The temperature of the deep-cooling unit can be determent by using the measured
mA-output values. To calculate the temperature, please use the following formulas:
