Technical Tests – J 572 812

1

General

Technical tests are performed via the technical test screen. The desired technical test is set by pressing the corresponding button on the OIT display. The test will be automatically deactivated when exiting the screen.

Technical tests are automatically deactivated, if the OIT is not used for 30 seconds.

2.1

Master Step Band Overspeed 15%

Hint! This test can only be performed during normal operation.

This test must be activated during standstill with the unit ready for operation. Start the unit in the desired direction of travel. Following start-up delay (approx. 15 seconds), the speed limit is set to a shutdown with an overspeed error "E_3E". To acknowledge the error press the reset button on the OIT display.

2.2

Master Step Band High Overspeed 25%

Hint! This test can only be performed during normal operation.

This test must be activated during standstill with the unit ready for operation. Start the unit in the desired direction of travel. Following start-up delay (approx. 15 seconds), the speed limit is set to a shutdown with a high overspeed error "E_CF". To acknowledge the error press the reset button on the OIT display.

2.3

Master Step Band Underspeed 50%

Hint! This test can only be performed during normal operation.

This test must be activated during standstill with the unit ready for operation. Start the unit in the desired direction of travel. Following start-up delay (approx. 15 seconds), the speed limit is set to a shutdown with an underspeed error "E_3F". To acknowledge the error press the reset button on the OIT display.

2.4

Slave Step Band Overspeed 15%

Hint! This test can only be performed during normal operation.

This test must be activated during standstill with the unit ready for operation. Start the unit in the desired direction of travel. Following start-up delay (approx. 15 seconds), the speed limit is set to a shutdown with an overspeed error "E_30". To acknowledge the error press the reset button on the OIT display.

2.5

Slave Step Band High Overspeed 25%

Hint! This test can only be performed during normal operation.

This test must be activated during standstill with the unit ready for operation. Start the unit in the desired direction of travel. Following start-up delay (approx. 15 seconds), the speed limit is set to a shutdown with a high overspeed error "E_CE". To acknowledge the error press the reset button on the OIT display.

2.6

Slave Step Band Underspeed 50%

Hint! This test can only be performed during normal operation.

This test must be activated during standstill with the unit ready for operation. Start the unit in the desired direction of travel. Following start-up delay (approx. 15 seconds), the speed limit is set to a shutdown with an underspeed error "E_31". To acknowledge the error press the reset button on the OIT display.

2.7

Motor Overspeed 15%

Hint! This test can only be performed during normal operation.

This test is only available when the unit is equipped with a speed monitor.

This test must be activated during standstill with the unit ready for operation. Start the unit in the desired direction of travel. Following start-up delay (approx. 15 seconds), the speed limits are set to a shutdown with a motor overspeed error "E_18". To acknowledge the error, press the RESET button on the OIT display.

2.8

Motor High Overspeed 25%

Hint! This test can only be performed during normal operation.

This test is only available when the unit is equipped with a speed monitor.

This test must be activated during standstill with the unit ready for operation. Start the unit in the desired direction of travel. Following start-up delay (approx. 15 seconds), the speed limits are set to a shutdown with a motor overspeed error "E_CC". To acknowledge the error, press the RESET button on the OIT display.

2.9

Motor Underspeed 50%

Hint! This test can only be performed during normal operation.

This test is only available when the unit is equipped with a speed monitor.

This test must be activated during standstill with the unit ready for operation. Start the unit in the desired direction of travel. Following start-up delay (approx. 15 seconds), the speed limits are set to a shutdown with a motor underspeed error "E_1C". To acknowledge the error, press the RESET button on the OIT

2.10

Instant Lubrication

Hint!

This test can be activated both during inspection and normal operation, whereas the lubrication cycle itself can only be activated during normal operation.

The current lubrication off-period is set to 0, thus starting a new lubrication cycle. The lubrication fault is reset.

The start of the lubrication cycle can be delayed by up to 10 seconds.

If the technical test is activated, the solenoid valves for all grease points are activated successively. The grease point can be changed by pressing the "Next grease point" button, thus switching over to the next grease point. After the last grease point, lubrication is stopped and the overtravel time is set to 2 seconds.

For more detailed information, see Controller Instructions J 595 027, Operator Interface Terminal (OIT)

2.11

First Lubrication

Hint!

This test can only be activated during normal operation of the escalator.

This test is used for the initial lubrication. The technical test starts 3 successive complete lubrication cycles during normal operation. This initial lubrication is a prerequisite for an optimum lubrication of the chains. Once the 3 successive lubrication cycles are successfully completed, the test is exited automatically. If the unit is stopped or if a lubrication fault occurs, the counter is automatically stopped.

For more detailed information, see Controller Instructions J 595 027, Operator Interface Terminal (OIT)

2.12

Lubrication System Check

Hint!

This test can be activated both during operation of the escalator as well as during standstill.

This technical test is used to fill the lubrication system, to check the lubrication system for leakages, to check the operation of every single grease point and to fill the distributor.
