Description
The setpoint is used to enable/disable the Overheat protection, which is used for
limitation of the gen-set power when there is not enough heat outlet from the gen-
set to avoid shutdown due to oveheating.
If the Overheat protection is enabled and the temperature at the logical analog
input LdCtrl:TByPwr:
 increases over the setpoint TempByPwr Treq, the Temperature-By-Power
load control loop is temporarily activated to reduce the power and
consequently the temperature.
 returns back under the setpoint TempByPwr Treq, the Temperature-By-
Power regulation loop is deactivated and previous load control mode (e.g.
Baseload) takes place.
NOTE:
See more information about the Temperature-By-Power load control mode in the
description of the setpoint TempByPwr Treq.
