4.2 Conditions for activation

If the conditions for enabling the function are all true, the gas cooler will be bypassed depending on the gas
temperature measured downstream of the bypass.
Within the activation interval, the bypass function can be controlled either using a set point and a differential,
or with modulating control. In the first case, the analogue or digital output will operate in ON/OFF mode, in
the second case a 0-10V analogue output will be used for modulation. Screen Eeab31 is used to configure
the type of control.
Configuration with digital output
cod. +030220595 - 1.2 - 13.08.2020
Screen Eeaa27 is used to configure the temperature probe
located downstream of the gas cooler bypass.
Gas cooler bypass is activated if the temperature downstream
of the bypass is lower than the specified threshold for the set
time (screen Eeab26). It is disabled for safety reasons when
reaching the limit set point. These values can be configured
on screen Eeab32.
