Apparatus for vertically closing an opening and method for identifying a service need and/or a safety issue for the same

A monitoring system comprising:

• one or more apparatuses for opening and closing an opening, each apparatus comprising:
• a shielding element configured to be in a first state in which said opening is covered by said shielding element and thereby closed, and a second state in which said opening is uncovered by said shielding element;
• a motor configured to drive said shielding element between said first and second state, said motor being provided with a thermal circuit breaker;
• a plurality of sensor arrangements;
• and
• a condition monitoring device configured to receive sensor data from at least one of said plurality of sensor arrangements;
• an on-site data node configured to receive the sensor data from the condition monitoring device of each of said one or more apparatuses, and to transmit reference data to the condition monitoring device of each apparatus of said one or more apparatuses;
• and
• an external database configured to receive the sensor data from the condition monitoring device of each of said one or more apparatuses or from the on-site data node, and to transmit the reference data to the condition monitoring device of each of said one or more apparatuses or to the on-site data node,
• wherein at least one of the plurality of sensor arrangements of each of said one or more apparatuses is a temperature sensor configured to determine a temperature in the motor and, thereby, detecting the state of said thermal circuit breaker, wherein the temperature sensor is positioned inside the motor,
• wherein the condition monitoring device of each of said one or more apparatuses is configured to receive sensor data from the plurality of sensor arrangements, wherein the sensor data received from the temperature sensor represents the temperature in the motor, and wherein the condition monitoring device is configured to directly or indirectly compare said sensor data with the reference data, being received from the on-site data node and/or the external database, such that a service need and/or a safety issue can be identified, and
• wherein the condition monitoring device of each apparatus of said one or more apparatuses is further configured to transmit the received sensor data to at least one of the on-site data node or the external database, wherein at least one of the on-site data node or the external database is configured to store the received sensor data.
