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 diff erential,
or with modulating control. In the fi rst 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 confi gure
the type of control.

Screen Eeaa27 is used to confi gure 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 specifi ed threshold for the set
time (screen Eeab26). It is disabled for safety reasons when
reaching the limit set point. These values can be confi gured
on screen Eeab32.
