Checking the Emergency Stop
3. Open the switch cabinet doors of the AC cabinet.
4. Make sure that the emergency stop on the outside
of the device is not activated.
5. Tape all door contact switches to the "On" position.
☑ During normal operation, both signal lights (A)
of the emergency stop relay must be illuminated.
6. If the emergency stop is activated, the signal lights
of the emergency stop relay must switch to "OFF".
☑ The Sunny Central Control displays error
message "206" and the fault must be
acknowledged manually.
7. Unlock the emergency stop and acknowledge the
fault on the Sunny Central Control. The fault is only
displayed on the Sunny Central on which the emergency stop was activated.
8. Release door contact switches (remove the adhesive tape).
