7.3.2 Operating mode changeover to internal load controller
To improve availability, a potential-free contact at inputs X62 pin 1 / X62 pin 2 can be
used to switch from any of the other operating modes to the internal load controller. In
that case, setpoint W1 applies. For the selected external operating mode, the switch
connected to X62 pin 1 / X62 pin 2 is open. To switch over to the internal load
controller, the switch closes.
