Travel Measurement - Siemens SIDOOR AT40 System Manual

The energy values are retentively stored every hour. After a restart, the energy measurement
starts with the last retentively stored value.
Note
Power failure
After a power failure, the energy values are reset to the last stored value.
Note
If the door is obstructed, or if there is an opening or closing command in the end positions, the
motor is energized but the door does not move. This means that the electrical energy consumed
by the motor increases continuously, but the mechanical energy generated remains unchanged.
Application example:
Upon arrival on one floor and before leaving the floor, the total energy can be queried from the
door control unit. The difference between the two energy values corresponds to the converted
motor energy for one floor. Since all door movements, i.e. even travel with obstruction and
reversing, are taken into account here, the energy requirement can be calculated for each travel.

Travel measurement

Description of function (as of FW version AT40 V01.48)
During door travel, the controller measures various motor and door mechanics data. In addition,
changes in the driving characteristics of the motor and the door can be detected and evaluated
for maintenance purposes using this data.
The following travel data are measured:
• Opening and closing times of the door
• Mechanical door energy
• Motor peak current in the slow start and end distance
• Mean power dissipation of the motor
• Current motor power
Opening and closing times of the door
• Time for the full opening operation
• Time for the full closing operation
• Opening time outside of the slow start distance
• Closing time outside of the end distance
If the measured times increase over time, this can be a sign of mechanical problems,
contamination or wear.
