4.3.5 Configuring the temperature curve for the cooling air control option for device types
M-AC and H-AC
Select device file "MCU", set the measuring system to "Maintenance" mode and enter
the Level 1 password (
p. 124, Table 3).
Select directory "MCU/Configuration/I/O-Configuration/Output Parameters" and set the
temperature limit "Ta" or "Tb" for the sender/receiver unit. The temperature limit should
be approx. 20 K above the gas dew point (+150 … +180 °C), the hysteresis should be
approx. 2°C.
Fig. 127 Temperature limit configuration
Cooling air control function check
Set the temperature limit close to the ambient temperature of the S/R units and check
whether the cooling air control switches on and off.
NOTICE:
A firmware update is necessary for MCU firmware versions older than 1.0.50.
