Commissioning
3.3.1
Commissioning the control
As soon as the mains voltage is connected, the control begins the auto‐
mated commissioning process.
Display: [Commissioning]
There is a self-test of the rechargeable battery, mains connection and
motor control components. The motor-powered flap is opened and
closed once.
After a successful self-test, the control switches to normal operation -
the motor-powered flap is opened.
Display: [Normal operation / NRV opened]
Faults detected during the self-test are shown on the screen.
