Procedures for system safety testings and for space-time measuring elevator car movement are described here.
The main switch of the controller must be switched off by every maintenance and at least 365 days after the last switch off and on.
This procedure is mandatory and must be followed in order to start the Autotest of the ELGO LIMAX CP33 and FUJI LM2 components.
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 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 reset UCM).
Test 3: Measure of the stopping space and time in UP direction at rated speed
Before starting the test, move the empty elevator car to the ground floor.
During the test, the elevator car will move upwards up to the second last floor (AGH for two stops installations); now the elevator car stops. After the elevator 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 elevator car to the top floor.
During the test, the elevator car will move downwards up to the first floor (AGB for two stops installations); now the elevator car stops. After the elevator 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 elevator car (EN 81 point 14.2.1.2)
Before starting the test, move the elevator car to the floor where you want to take the measure.
During the test, the elevator car will move upwards until the re-leveling function is activated; now the elevator car is re-leveled. After the elevator 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 elevator car (EN 81 point 14.2.1.2)
Before starting the test, move the elevator car to the floor where you want to take the measure.
During the test the elevator car will move downwards until the re-leveling function is activated; now the elevator car is re-leveled. After the elevator 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 elevator car to the ground or top floor.
During the test the elevator car will move towards the shaft end until the safety chain opens (or until the FCO input is detected). After the elevator 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 elevator car can be moved beyond the limit switch through the inspection control panel in the machine room (in inspection mode the movement beyond the top and bottom floor is disabled) to put the elevator car or the counterweight on the shock absorbers and perform the rope slipping test. Move the elevator car out of the limit switch area and put the installation in normal operation mode (if the second NO contact of the FCO input is connected, you must reset FCO in the menu “Faults”).
Test 8: Motor run time test (EN 81 point 12.10)
Before starting the test, move the elevator car to the ground or top floor.
During the test the elevator car will move towards the opposite extreme floor at null speed. After 5 seconds, the up/down run time error will be detected (check in the menu “Faults”). Clear all errors to put the installation in normal operation mode again.
Test 9: System balancing test
Before starting the test, place the cab on the ground floor with the weight suited to balance the system itself (typically 50% of the maximum load). During the test the cabin will start in the direction of the highest floor and the absorbed current at the middle of the shaft will be displayed. The cabin will then move to the lowest floor, once again displaying the absorbed current at the middle of the shaft. The values will also be preserved after the end of the test for evaluation purposes.
Test 10: ELGO UCM in UP direction (ELGO-CP)
Before starting put the empty elevator car to the floor where you want to make the test (excluded top floor).
During the test the lift starts in UP direction up to the end of door zone; at this point ELGO will give a fault (Fault ELGO Cod. 24) and stop the elevator car (OC contact open) and on the display is showed space and time of system intervention (to be compared with Eelevator N81 point 9.11.5).
IMPORTANT: spaces must be calculated before as a sum of intervention times (controller, Stopping device)
After test it is necessary a fault reset (Menu Fault, Reset) to put the ELGO LIMAX33-CP in normal operating mode.
Test 11: ELGO UCM in DOWN direction (ELGO-CP)
Before starting put the empty elevator car to the floor where you want to make the test (excluded bottom floor).
During the test the lift starts in DOWN direction up to the end of door zone; at this point ELGO will give a fault (Fault ELGO Cod. 24) and stop the elevator car (OC contact open) and on the display is showed space and time of system intervention (to be compared with EN81 point 9.11.5).
IMPORTANT: spaces must be calculated before as a sum of intervention times (controller, Stopping device)
After test it is necessary a fault reset (Menu Fault, Reset) to put the ELGO LIMAX33-CP in normal operating mode.
Test 12: OSG and Safety Gear test (ELGO-CP + eSGC)

During the test the lift starts in high speed and the OSG+eSGC will open at nominal speed (Fault ELGO Cod. 9) stopping the elevator car.
After test it is necessary a fault reset (Menu Fault, Reset) to put the ELGO LIMAX33-CP in normal operating mode.
Test 13: ETSL system intervention in UP direction (ELGO-CP)
Optional function. In normal condition protection open OC contact if the cabine’s speed is too high during the UP direction trip (risk for counterweight on the buffers).
During the test ELGO consider the middle of the Shaft as if it were the Upper Reference point.
Before starting the test, place the empty cabin on the ground floor (lowest floor) without load to simulate the worst conditions. During the test the cabin will start towards the highest floor. Before the mid-point of the lift shaft the ELGO will open the OC safety contact (Fault ELGO Cod. 16) and the elevator car will stop for brake intervention before reaching the half compartment position (assumed as the simulated buffer position).
The intervention time (from the opening of the OC contact) and distance from the mid-point of the lift shaft (safety margin with the buffers) are displayed.
Test 14: ETSL system intervention in DOWN direction (ELGO-CP)
Optional function. In normal condition protection open OC contact if the cabine’s speed is too high during the UP direction trip (risk for cabine on the buffers).
During the test ELGO consider the middle of the Shaft as if it were the Lower Reference point.
Before starting the test, place the cabin on the top floor with a fully loaded lift cabin to simulate the worst conditions. During the test the cabin will start towards the bottom floor. Before the mid-point of the lift shaft the ELGO will open the OC safety contact (Fault ELGO Cod. 16) and the elevator car will stop for brake intervention before reaching the half compartment position (assumed as the simulated buffer position).
The intervention time (from the opening of the OC contact) and distance from the mid-point of the lift shaft (safety margin with the buffers) are displayed.
Test 15: Reduced Head Safety test (EN 81-21 – ELGO-CP+eSGC)
Test for Reduced Head and Protection system based on ELGO+eSGC.
Protection intervention is after a shaft access, in the point given by distance TRIPS (Monitor Encoder) from the Upper Reference position (counterweight on the buffer).
During the test ELGO intervention is given also with lift in normal mode, without any shaft access simulation. Before starts the test put the lift under the intervention point.
During the test elevator car will start in UP direction (to the top floor). When elevator car reaches the intervention point, ELGO will open OC contact and switch off the eSGC output stopping the elevator car (Fault ELGO Cod. 4).
After test it is necessary a fault reset (Menu Fault, Reset) to put the ELGO LIMAX33-CP in normal operating mode.
Test 16: Reduced Pit Safety test (EN 81-21 – ELGO-CP+eSGC)
Test for Reduced Pit and Protection system based on ELGO+eSGC.
Protection intervention is after a shaft access, in the point given by distance TRIPD (Monitor Encoder) from the Lower Reference position (Cabine on the buffer).
During the test ELGO intervention is given also with lift in normal mode, without any shaft access simulation.
Before starts the test put the lift over the intervention point.
During the test elevator car will start in DOWN direction (to the bottom floor). When elevator car reaches the intervention point, ELGO will open OC contact and switch off the eSGC output stopping the elevator car (Fault ELGO Cod. 5).
After test it is necessary a fault reset (Menu Fault, Reset) to put the ELGO LIMAX33-CP in normal operating mode.
Test 17: OC Safety contact test (ELGO-CP)
Only for installation with ELGO-CP.
Test checks if the safety contact OC inside the ELGO works properly: contact opens for 0,5 sec. (you can check the safety chain open from SE3 point).
Test is automatically executed one time a day.
It is no further operation needed after the test (lift is in normal Service).
Test 18: Door Disable
Test for temporary disabling door operators.
Test is useful if technician needs to make some test with lift in normal mode but without the risk some user can enter in the elevator car.
It is possible to program a time of 1/5/10/30/60 minutes.
Time is valid also if Lift will be put in inspection / Normal again.
At the end of timer, lift comes back in normal mode.
Test 19: Black out Simulation
Only for installation with full emergency option. Lift behaviour is the same you have when power supply goes off, so it make an automatic emergency moving the car to the floor and opens the door.
Test 20: Telephone call for low batteries level simulation
Controller send command to DMCPIT (output ALARM Enable) as if the battery level was wrong for an emergency call. This signal has to be connected to the telephone’s input for emergency call.
Test 21: Simulation of system shutdown need (ELGO or VVVF system only)
The system simulate a long time without any shutdown.
– At first execution, system simulate a switch-on beyond 9 months (270 days), as an effect only the information defect “1 = Reset Cod 9”. In the Errors menu DAY COUNTER = 270 is displayed. Lift continues to operate regularly.
– At second execution, system simulate a switch-on over 12 months (365 days), as an effect the blocking fault “1 = Reset Cod 12”. The lift stops at the floor without being able to take further calls. In the Errors menu DAY COUNTER = 365 is displayed. To return in normal operation, the main power switch must be turned off and then on again.
Test 22: Integrated Weighing Calibration Procedure (VVVF system only)
The Test must be repeat twice, the first for the full load (100%), the second time (110%) for the overload measurement.
Before starting the test, place the cabin on the ground floor or on the top floor.
Select in order:
– Test 22 – 100%: Put into the car the FULL LOAD. When you confirm the test lift automatically will make a start from each floor in both direction. During the test doors will not be enabled to keep constant load into the cabin. Test finish when the cabin come back to the starting floor and door opens. On the Playpad is showed “End reg.”.
– Test 22 – 110%: Add into the car 10% of the load with a minimum of 75 Kg. When you confirm the cabin close the door (without moving from the floor) and the overload will be activated (and so the door will be open. On the Playpad is showed “End reg.”.
After the Calibration procedure check the status of parameter “Integrated Load Weighing” in the menu .
Attention:
Calibration Procedure Must be repeated in case of any changing into the cabin (panels, flooring, COP changing etc.) or on the counterweight (lift balancing).
Test 23: Measure of the stopping space and time in UP direction at rated speed with Safety Gear (only OSG A3)
Before starting the test, move the empty car to the ground floor.
During the test, the car will move upwards and after reaching the nominal speed, as soon the car reach the first floor (AGH for two stops installations) the controller removes the OSG’s A3 pin causing the stop of the lift. After the car has been stopped, the distance covered from the second last floor and the stopping level and the stopping time are shown. To control only the safety gear as a locking system, when starting the lift keep the brakes energized by manually operating the contactors.
Test 24: Measure of the stopping space and time in DOWN direction at rated speed with Safety Gear (only OSG A3)
Before starting the test, move the full loaded car to the top floor.
During the test, the car will move downwards and after reaching the nominal speed, as soon the car reach the first floor (AGB for two stops installations) the controller removes the OSG’s A3 pin causing the stop of the lift. After the car has been stopped, the distance covered from the second last floor and the stopping level and the stopping time are shown. To control only the safety gear as a locking system, when starting the lift keep the brakes energized by manually operating the contactors.
Test 25: Measure of the stopping space and time of Safety Gear (ELGO-CP + eSGC + OSG-A3)
Test can be executed in both directions. Test will stop the cabine at next floor (inside the door zone) in order to help the car’s load/unload operations to release the safety gear.
In case of two stop lift (or in case of cabine near the end of the shaft) cabine will be stopped on the AGB/AGH activation.
 | Upward Test (bidirectional Safety Gear): Before starting put the empty car to the floor where you want to make the test (must be present at least two floors over the cabine otherwise cabine will stop on AGH). After selecting test it is necessary to set the test speed (10 % ↔ 100 % of nominal speed) based on the characteristics of the system to avoid damage to the cabin structure. Turn the PME’s knob on INSPECTION. Keep the OSG’s key on “SET” position for the entire duration of the test. Press the button ↑ for the entire duration of the test. Lift moves in up direction up to the next door zone, where power of A3 pin will be removed causing the mechanical Safety Gear stop. After the car has stopped, the distance covered from the floor level is shown with the stopping time. After the test release the button ↑, release the OSG’s key and move the lift in down direction to release the safety Gear (it may be necessary to add some load into the cabin to facilitate the release). |
| Downward Test: Before starting put the car to the floor where you want to make the test (must be present at least two floors under the cabine otherwise cabine will stop on AGB). Put full load inside the cabine (or more than full load if test requires). After selecting test it is necessary to set the test speed (10 % ↔ 100 % of nominal speed) based on the characteristics of the system to avoid damage to the cabin structure. Turn the PME’s knob on INSPECTION. Keep the OSG’s key on “SET” position for the entire duration of the test. Press the button ↓ for the entire duration of the test. Lift moves in down direction up to the next door zone, where power of A3 pin will be removed causing the mechanical Safety Gear stop. After the car has stopped, the distance covered from the floor level is shown with the stopping time. After the test release the button ↓, release the OSG’s key and move the lift in up direction to release the safety Gear (it may be necessary to remove some of the load from the cabin to facilitate the release). |
Test 26: UCM Measure of the stopping space and time (ELGO-CP + eSGC + OSG-A3)
Test can be executed in both directions. Test will stop the cabine as soon the cabine will exit from the door zone.
| Upward Test: Before starting put the empty car to the floor where you want to make the test (don’t execute test at top floor). After selecting test it is enabled the door’s safety bypass for the entire duration of the test. Turn the PME’s knob on INSPECTION. Keep the OSG’s key on “SET” position for the entire duration of the test. Press the button ↑ for the entire duration of the test. Lift moves in up direction up to the end of door zone, where LIMAX33-CP’s UCM circuit remove power of A3 pin causing the mechanical Safety Gear 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. After the test release the button ↑, release the OSG’s key and move the lift in down direction to release the safety Gear (it may be necessary to add some load into the cabin to facilitate the release). After test it is necessary a fault reset (Menu Fault, Reset) to put the ELGO LIMAX33-CP in normal operating mode. |
