Checking the Emergency Shut-off
3. Open the switch cabinet doors of the AC cabinet.
4. Ensure that the emergency shut-off 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 shut-off relay must illuminate.
6. If an emergency shut-off switch is now activated, the
signal lights of the "Off" emergency shut-off relay
must switch.
☑ The Sunny Central Control displays error
message "206" and the fault must be
acknowledged manually.
