The automatic door operator (30) has a motor (34) capable of causing movement of the door member (10), a controller (31) for controlling operation of the motor (34), and the automatic door operator (30) being operable in a testing mode (60) and an operational mode, wherein the controller (31) is configured, in the testing mode (60), to automatically determine at least one test parameter; and causing an action in response to the determined test parameter. ## Claims ### Claim 1 An entrance system comprising: a swing door member having a door leaf, and an automatic door operator having: a motor capable of causing movement of the door member, a controller for controlling operation of the motor, the automatic door operator being operable in a testing mode and an operational mode, wherein the controller is configured, in the testing mode, to: automatically determine at least one test parameter; and cause an action in response to the determined test parameter; and a lock assembly connected to a power supply and having a lock type, wherein the lock assembly is configured to put the entrance system in a locked position, and wherein the controller is further configured to: put the power supply in a power off condition; put the entrance system in the locked position; control said motor to initiate a movement of said door leaf between a shut closed position of said door leaf and a swung open position of said door leaf, and evaluate if the motor causes movement of the door leaf while the lock assembly is in the locked position, wherein the at least one test parameter comprises a result of the evaluation, and wherein the result is a determination whether the lock type is a fail-safe lock type or a fail-secure lock type. ### Claim 2 (depends on 1) The entrance system as defined in claim 1, wherein the entrance system further has a sensor unit, the sensor unit comprising a door angle sensor, and wherein the controller is further configured, in the testing mode, to: cause movement of said door leaf between a shut closed position of said door leaf and a swung open position of said door leaf; obtain measurement readings of said door angle sensor during said movement; and determine the at least one test parameter at a plurality of different door leaf angles (α). ### Claim 3 (depends on 2) The entrance system as defined in claim 2, wherein the at least one test parameter is determined at least based on the determined door leaf angles (α). ### Claim 4 (depends on 2) The entrance system as defined in as defined in claim 2, wherein the door angle sensor comprises at least one of: an accelerometer; and a gyroscope. ### Claim 5 (depends on 1) The entrance system as defined in claim 1, wherein the at least one test parameter is determined based on at least one system parameter. ### Claim 6 (depends on 5) The entrance system as defined in claim 5, wherein the at least one system parameter is pre-stored in the controller and/or manually added to the controller during the testing mode. ### Claim 7 (depends on 5) The entrance system as defined in claim 5, wherein the at least one system parameter relates to a width of the door leaf and/or a mass of the door leaf. ### Claim 8 (depends on 1) The entrance system as defined in claim 1, wherein the least one test parameter is a torque generated by the motor. ### Claim 9 (depends on 1) The entrance system as defined in claim 1, wherein the controller is further configured, in the testing mode, to: analyze the at least one determined test parameter against at least one pre-determined threshold. ### Claim 10 (depends on 9) The entrance system as defined in claim 9, wherein the at least one pre-determined threshold relates to a maximum or a minimum allowed closing torque or a maximum or minimum allowed opening torque of the entrance system. ### Claim 11 (depends on 1) The entrance system as defined in claim 1, further comprising a linkage connected to the automatic door operator and the door leaf for transferring torque generated by the motor to the door leaf. ### Claim 12 A method of operating an entrance system which comprises a swing door member having a door leaf, and which furthermore comprises an automatic door operator having a motor capable of causing movement of the door member, a controller for controlling operation of the motor, and a lock assembly connected to a power supply and having a lock type, wherein the lock assembly is configured to put the entrance system in a locked or unlocked position, the method involving: operating the automatic door operator in a testing mode which involves: automatically determining at least one test parameter; and causing an action in response to the determined test parameter, wherein the step of automatically determining comprises: actuating the lock assembly to put the entrance system in the locked position; controlling said motor to initiate a movement of said door leaf between a shut closed position of said door leaf and a swung open position of said door leaf, evaluate if the motor causes movement of the door leaf while the lock assembly is in a locked position, wherein the at least one test parameter comprises a result of the evaluation, and wherein the result is a determination whether the lock type is a fail-safe lock type or a fail-secure lock type. ### Claim 13 (depends on 12) The method according to claim 12, wherein the swing door member further has a sensor unit mounted to the door leaf, the sensor unit comprising a door angle sensor, and wherein the testing mode further involves, in a step before automatically establishing at least one test parameter: controlling said motor to cause movement of said door leaf between a shut closed position of said door leaf and a swung open position of said door leaf; obtaining measurement readings of said door angle sensor during said movement; and determining the at least one test parameter at a plurality of different door leaf angles (α). ### Claim 14 (depends on 13) The method according to claim 13, wherein the step of automatically determining at least one test parameter is at least based on the determined door leaf angles (α).
