7.3.6 [d 51], [d 52] - Mains synchronising pulse
A check is made to see whether the mains synchronising pulse for switching the cooking zones on and
off arrives at the corresponding module. To this end the relevant mains relay is switched on, then a check
is made for 2 seconds to see whether the signal triggers an interrupt. Then the mains relay is switched
off again. If no mains synchronising signal has been registered, a “0“ appears in the display “Diagnosis
result“, a “1“ appears if the signal has triggered an interrupt.
The module designation corresponds to the internal view (see Annex B).
7.4 Ending the diagnosis mode
♦ The diagnosis mode can be ended at any time by activating the main switch button OFF.
♦ The control is automatically switched off five minutes after the last button was activated.
