Arcode UCM (Unintended Car Movement) Test Instructions

ARCODE UCM (Unintended Car Movement) Test Instructions 1. Considerations before UCM Test 1.a. Relevant staff should take necessary precautions for the safety of the passengers as well as himself of all actions at risk.

Prevent the elevator run by someone else, Be sure that there is nobody in the elevator shaft (hoist way), Be sure that all elevator doors are closed . 1.b. There should exist DBR (Door Bridging) card on ARCODE. If there is a bridge between 140-140P inputs on ARCODE, this bridge should be removed. 1.c. UCM test function exists if the firmware version of ARCODE is 20.04.2014 and later. This function should be used for UCM test. The firmware updating should be done for older versions of the devices. (See ARCODE Easy Installation Manual). 1.d. In order to simulate the worst load condition in UCM test: - the empty car is moved in up direction at the top of the shaft (from the one below floor to the top) - the full loaded car is moved in down direction at the bottom of the shaft (from the one above floor to the  bottom) 1.e. "UCM test function" mode is activated as follows:  Note: While doing the parameter settings, “Quick access feature” of AREM can be used. For For this: - F3 button is  menu. button is pressed while in “Device Parameters”  menu. - The related parameter code is entered. For example:  P0069.  P0069. - The related parameter is activated by pressing enter button. button.

- Tools button is button is pressed on AREM. - "Device Parameters" screen Parameters" screen is entered. - The following settings is performed in order: " DBR board functions  Door safety circuit  bridging board (P0069): Installed" " Door pre-opening settings  Door pre opening function (P0071): (P0071): On" "Door pre-opening settings Door pre-opening  start distance (P0072): 20 cm."

Warning: After completing UCM test, " Acceptance  test tools (P0810)" parameter (P0810)" parameter should be set to "Off". "Off".

Figure-3: Activating UCM test function There exists 2 options in the "UCM the  "UCM test function" screen. The proper test method is chosen for the UCM protection equipment.

Figure-4: Choosing the UCM test method

- "UCM test in inspection speed": Test speed": Test is  performed in inspection speed. This can be used for UCM protection equipment that do not need full-torque test. - "UCM test in full-torque": Test full-torque": Test is performed with max. power the system allowed. This option should be used if UCM test will be done under the worst conditions (by taking into account the maximum acceleration effect of the driver system error). ARCODE moves the car with max. acceleration by applying in the indicated direction max. power to the motor the system allowed.

After choosing the UCM test method, the instructions shown in the screen are followed. When “START  “START ” is seen in the screen, 60 seconds countdown is started by pressing enter button. button. The countdown info is shown on ARCODE screen (“Ut ( “Ut 59” , “Ut 58”  ...)  ...) and audible warning is given. During this period, the car should be moved with recall up or recall down button. At the end of this period, ARCODE will automatically exit from "UCM test function" mode. function" mode.

1.f. UCM test should be done with doors closed for safety purposes!!!! But open doors should be simulated during testing. After pressing "START" button "START" button (ARCODE will bridge the doors). The open doors can be simulated by interrupting 130 signal (landing doors security circuit signal) on KBK-11. 1.g. During the test, the car should be moved with up or down button on the recall hand terminal. 1.h. At the end of UCM test, ARCODE gives “ UCM detection error” error” error and blocks the lift permanently. This error can’t be cleared even if the power is switched off and on. The system will not turn to the normal run mode without clearing the permanent error with a special action. To clear the permanent errors, the following actions should be performed:

- Tools button is pressed on AREM. - "System Tools" screen Tools" screen is entered. - "Clear permanent error" is error" is chosen and pressed enter button. button. - First, recall key is turned to “INSPECTION” and then “NORMAL” mode or power is switched off and on.

2. UCM (Unintended Car Movement) Test Procedure 2.a. UCM Test in Up Direction with Empty Car

The following steps should be performed in order. -

-

Move the car to the one below of the top floor. (See. 1.d). Empty the car (See. 1.d). Enable "UCM test function" mode function" mode (See. 1.e). After starting the countdown, remove the connection from terminal 130 on the KBK-11 board (See. 1.f). The car is moved by keeping pressed up direction button on the recall hand terminal (See. 1.g). After leaving the door zone, door bridging circuit hardware will open, because the 130 signal is interrupted. In this case, the power of the activating/stopping means will be also cut off, because the main contactors which are fed by safety circuit will drop. Emergency UCM stop occurs. ARCODE gives “ERROR CODE  error and the lift is kept out of service permanently. (PERMANENT):86 (PERMANENT):86 UCM DETECTION”  error The stopping distance is measured. Test is successful if the stopping distance is within acceptable values. The power is switched off and on. It is observed that the permanent UCM error still continues. The permanent error is cleared. (See. 1.h). It is observed that the lift turned to the normal run mode. Test is finished (See. 1.i).

2.b. UCM Test in Down Direction with Fully Loaded Car

The following steps should be performed in order. -

-

Move the car to the one above of the bottom floor (See. 1.d). Load the car with rated load (See. 1.d). Enable "UCM Enable "UCM test function"  mode (See. 1.e). function" mode After starting the countdown, remove the connection from terminal 130 on the KBK-11 board (See. 1.f). The car is moved by keeping pressed down direction button on the recall hand terminal (See. 1.g) After leaving the door zone, door bridging circuit hardware will open, because the 130 signal is interrupted. In this case, the power of the activating/stopping means will be also cut off, because the main contactors which are fed by safety circuit will drop. Emergency UCM stop occurs. ARCODE gives “ERROR CODE  error and the lift is kept out of service permanently.. (PERMANENT):86 (PERMANENT):86 UCM DETECTION”  error The stopping distance is measured. Test is success ful if the stopping distance is within acceptable values. The power is switched off and on. It is observed that the permanent UCM error still continues. The permanent error is cleared. (See. 1.h). It is observed that the lift turned to the normal run mode Test is finished (See. 1.i).
