ANNEX II: Test and measures
The following tests and measures may facilitate controls and tests to be performed before putting the
installation in service (EN81-X D) and during the periodic maintenance interventions (EN81-X E). Some
measures can be performed only through the encoder counting system.
Tests can be performed only if the installation is in normal operation mode; select parameter “test” to perform
the test and press ENTER to start it. The test procedure can be stopped by switching the installation to
inspection mode.
Test 1: Measure of the stopping space and time in UP direction, DMG UCM module in acceleration
out of the door zone
Before starting the test, move the empty car to the floor where you want to take the measure.
During the test, the car will move upwards until the end of that floor door zone; now the forced
intervention of the UCM module is activated and the car will thus stop. After the car has stopped,
the distance covered from the floor level is shown (to be compared to point 5.6.7.5 of EN81-20) and
the stopping time since the UCM activation. Important: the stopping distance must be calculated
before, considering the sum of intervention times (controller + stopping unit). After the test, the UCM
module must be reset (menu <Faults> reset UCM).
Test 2: Measure of the stopping space and time in DOWN direction, DMG UCM module
Before starting the test, move the empty car to the floor where you want to take the measure.
During the test, the car will move downwards until the end of that floor door zone; now the forced
intervention of the UCM module is activated and the car will thus stop. After the car has stopped,
the distance covered from the floor level is shown (to be compared to point 5.6.7.5 of EN81-20) and
the stopping time since the UCM activation. Important: the stopping distance must be calculated
before, considering the sum of intervention times (controller + stopping unit). After the test, the UCM
module must be reset (menu <Faults> reset UCM).
Test 3: Measure of the stopping space and time in UP direction at rated speed
Before starting the test, move the empty car to the ground floor.
During the test, the car will move upwards up to the second last floor (AGH for two stops
installations); now the car stops. After the car has been stopped, the distance covered from the
second last floor and the stopping level and the stopping time are shown.
Test 4: Measure of the stopping space and time in DOWN direction at rated speed
Before starting the test, move the full loaded car to the top floor.
During the test, the car will move downwards up to the first floor (AGB for two stops installations);
now the car stops. After the car has been stopped, the distance covered from the first floor and the
stopping level and the stopping time are shown.
Test 5: Re-leveling test with too high car (EN 81 point 14.2.1.2)
Before starting the test, move the car to the floor where you want to take the measure.
During the test, the car will move upwards until the re-leveling function is activated; now the car is
re-leveled. After the car has stopped, the distance at which the re-leveling starts and the intervention
time are shown. We recommend to perform the test at each floor to check the correct installation of
the re-leveling sensors.
Test 6: Re-leveling test with too low car (EN 81 point 14.2.1.2)
Before starting the test, move the car to the floor where you want to take the measure.
During the test the car will move downwards until the re-leveling function is activated; now the car
is re-leveled. After the car has stopped, the distance at which the re-leveling starts and the
intervention time are shown. We recommend to perform the test at each floor to check the correct
installation of the re-leveling sensors.
Test 7: Final limit switch test (EN 81 point 10.5)
Before starting the test, move the car to the ground or top floor.
During the test the car will move towards the shaft end until the safety chain opens (or until the FCO
input is detected). After the car has stopped, the distance between the intervention floor and the
limit switch intervention and the status of FCO input (NO contact for registering the limit switch
intervention) are shown. The car can be moved beyond the limit switch through the inspection
