Pitagora 4.0 – Test and measurements


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 pbe 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 pbe 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)


Before starting put the elevator car to the top or bottom floor.
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 17: OC Safety contact test (ELGO-CP)


Only for installation with ELGO-CP.
Test checks if the safety contact OC inside the ELGO works porperly: 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 temporarly 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: Telephon 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)


Controller send command to DMCPIT (output ALARM Enable) as if the battery level was wrong for an emeThe system simulate a long time without any shutdown.
– At first executiion, 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 executiion, 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)


Controller send command to DMCPIT (output ALARM Enable) as if the battery level was wrong for an emeThe system simulate a long time without any shutdown.
– At first executiion, system simulate a switch-on beyond 9 months (270 days), as an effect only the

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 automaticaly 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 minumum 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).
