Some Valuable Experiences in Maintenance Methods of OTIS OVF30 Frequency Inverter Board (ABA26800XU1 and ABA26800XU2)

The model of OTIS OVF30 Frequency Inverter is an early equipped in the 300VF control system of OTIS elevator. Due to the service life is longer (at least 10 years), there has a high damage rate of ABA26800XU1(or XU2) in the frequency inverter. ElevatorVip has accumulated rich maintenance experiences in the past few years, now we are showing the experiences of maintenance and how to troubleshoot issue to everyone as below:

OTIS OVF30 Frequency Inverter, OTIS Elevator 300VF Control System, OTIS Inverter Service Time, OTIS OVF30 Board Maintenance Method, ABA26800XU1, ABA26800XU2, OVF30 Frequency Inverter Maintenance Experience, OTIS Inverter UDX Light Flash Alternatively, OTIS OVF30 Board Fault Code X04A, OTIS OVF30 UDX Relay, OTIS OVF30 Ohmic Resistance, OTIS OVF30 BRK Light, Cheap OTIS OVF30 Frequency Inverter in USA, Elevator OVF30 Frequency Inverter Motherboard

 

Failure 1: Power on works well, fault code: ‘X04A’ displays on the frequency inverter board, the UDX light flash alternatively, UDX relay switch turn on and off alternatively, and BRK light doesn’t work.
Fault Point: This fault is generally caused by an issue in drive signal return circuit of IGBT. Generally, it is caused by that R118-R124=499 ohmic resistance is increased, please just replace the broken resistance, which works well.

Failure 2: Power on works well, fault code: ‘X04A’ displays on the frequency inverter board, the UDX light flash alternatively, UDX relay switch turn on and off alternatively, and BRK light is on once, then off.
Fault Point: This fault is generally caused by the limit value of current sampling resistor is increased in the current checking circuit. Usually, the resistance value of R146, R149, or R152 is increased, please replace it, which works well.

Failure 3: Power on doesn’t work properly, fault code: ‘!04A’ displays on the frequency inverter board.
Fault Point: The OTIS Elevator Test Tool (TT) is needed to troubleshoot the fault, if there displays ‘M4-2-1’ on the TT, which the fault is ‘UDX not pickd nc’ means UDX replay NC doesn’t work normally or action incorrect, in final it was found that the resistors in R78, R75, R77, and R83 had deteriorated, after replacing the deteriorated resistors, it started normally. If the fault code is ‘UDX not pickd no’ means the R78 is broken.

Tips: The OTIS Test Tool (Part number: GAA21750AK3) is important tool during maintenance of ABA26800XU1 and ABA26800XU2, which is useful tool according to fault code to check the fault point at your jobsite.

How to Use the Elevator Guide Rail Alignment Gauge at Your Installation Jobsite?

Definition of Elevator Guide Rail Alignment Gauge:

Elevator Rail Alignment Gauge, which is called Elevator Guide Rail Alignment Tool, or Ruler. It is a new kind of high precision elevator guide rail installation tool, and suited for guide rail installation technology with scaffold and no scaffold.

Guide rails are used to guide the vertical movement of an elevator in an elevator shaft. There are two guide rails on the opposite walls of the elevator shaft and the elevator is linked to the guide rails through guide shoes or guide rollers facing the guide rails. Guide rails are constructed from multiple guide rail sections that are connected to each other from their vertical ends to form a continuous guiding structure for the elevator. The connection between two adjacent guide rail sections is secured through a connecting element, for example a fishplate, that is attached to both guide rail sections through bolts or similar. The guide rails are attached to the walls of the elevator shaft through brackets. The accurate alignment of the adjacent guide rail sections is necessary to prevent disturbances in the elevator path when it moves over a junction of two guide rail sections and to ascertain that the guide shoes or guide rollers touch the guide rails. The guide rail alignment gauge and the method for correcting guide rail alignment errors are in particular, but not only, intended for elevators, especially for passenger or cargo elevators of buildings. So, the elevator guide rail alignment gauge is a safety tool to ensure the elevator car is running in safe. Here is the Elevator Guide Rail Alignment Gauge from ElevatorVip. If you need, please contact us.

What should you do if the OTIS Elevator Inverter REGEN OVFR03B-401 KAA21310ABD2 is suspended production?

As is known to all of us, OTIS Elevator Inverter REGEN OVFR03B-401 KAA21310ABD2 is produced in 2013, so far this year the model has been discontinued, but many of our customers have used this model of inverter on their elevators. Electronic components have a life span, and over that time, some of them will break down. Recently, ElevatorVIP has received helps from customers in India, their frequency converter is broken. And what should I do?

Do worry, we said. Let us to check in our warehouse, maybe they are in stock. Unfortunately, due to the high demand from customers, this model of frequency converter has been sold out, but we have a placement model to place it, that is OVFR03B-402 KAA21310ABF1 model, which pictures are shown as below:

What will happen if the escalator handrail guide block is worn out?

As you know, there are two handrail belts in one escalator, and two handrails are running with the nylon guide rail slider (slider block) under itself, runs every day. And each mechanical escalator spare part will be worn out in final. If the escalator handrail guide rail is worn out, which causes the running speed of two sides are different, even one or two sides are running slower than the escalator motor. Thereby it can cause passengers to lean back, there may be a risk of falls.
So, if you discover your escalator has the situation likes above we said, just replace the nylon handrail guide rail slider, it is so cheap, just takes a bit time of you. Here is the cheap escalator nylon handrail guide block: https://www.elevatorvip.com/product/escalator-mechanical-parts-guide-block-eev477an1/
