The most common, exemplary faults in controllers from the GfA family:

1.2, 1.3 – a problem with the safety chain circuit preventing the gate from moving

3.7 – internal data inconsistency / problems with information transmission

3.8 – the controller heats up to too high a temperature

5.6 – the controller does not detect gate movement despite current flowing to the drive

6.7, 6.9 – damage to the frequency converter at the drive

controller display is dark – a problem with the internal power supply of the controller

Other common problems with products from the GfA family resulting from issues beyond the controller electronics itself:

3.1, 3.2, 8.1 – improper gate position reading | verification of the DES encoder’s functionality in the drive recommended

FAQ – Frequently Asked Questions

How to disassemble the gate controller? The whole unit or just the electronics?

What is the effectiveness of repairs?

Controllers that can be repaired are restored to 100% functionality. The electronics are regenerated in such a way as to restore the technical functionality and lifespan of a new device.

Devices after regeneration are cyclically tested, all functions are checked to ensure that the gate will work flawlessly for a long time after the repair.

A very important factor affecting the possibility of repair is whether someone without sufficient knowledge and experience attempted to repair it independently. In such cases, the chance of repair is significantly reduced due to inadvertently causing additional damage that cannot be rectified.

How many of the controllers sent to BRAMY-SERWIS are repaired? We estimate that 29 out of 30 devices undergo repair. One out of 30 units unfortunately falls into the category of devices that have been previously tampered with or are from the cheapest gate manufacturers (cheap, Chinese electronics).

Do you provide a warranty for repaired devices?

Yes, we offer a 12-month warranty on the repair. This is exactly the same duration as most manufacturers provide for new devices. How is this possible? Because we have been specializing in these repairs for many years and make every effort to comprehensively renew the electronics, restoring their factory lifespan.

We recommend having the controller installed and commissioned by a gate service provider that we cooperate with. However, it is not a mandatory condition to maintain the warranty. It is possible to dismantle and later reinstall the controller by maintenance personnel at your facility. You can count on our remote support during the connection and commissioning of the gate.

During the repair, we verify the cause of the controller’s damage and provide specific recommendations to prevent further damage. This guarantees the correct functioning of the device. If the recommendations are not followed, it will be evident in the device, so it’s important to heed our advice to maintain the warranty.

How much does controller repair cost?

Please send your inquiry to: support@bramy-serwis.pl

The minimum information we need for an estimate includes: a photo or model of the damaged controller, and a description of the malfunction – how it manifests during the gate operation. Error codes displayed during operation are also helpful.

You will receive an offer from us no later than the next business day after sending the message.

Gate service providers are registered in our system as cooperating services, and based on this, we provide a dedicated price list for services and offer partnership discounts to maintain the retail prices of services as suggested by us.

If repair of the device is not possible, we only charge for the return shipping of the damaged device.

I have accepted the repair cost, what’s next?

Safely pack the entire, complete controller (including the rear housing and front cover).

Include the received offer or a brief letter – a repair order with your company details, contact person’s information (name, surname, email address, and phone number), and a short description of what is happening with the device.

Send the package to:

BRAMY – SERWIS
Popowo 57
64-510 Wronki
Poland

You can use any courier company of your choice – you send the device independently, at your own expense, with your favorite courier company. Remember to pack the shipment securely. Damages during shipping regularly occur, and this is usually due to inadequate packaging in 90% of cases.

As soon as we receive the controller, you will be notified. We will keep you informed about the progress of diagnostics/repair through our proprietary service system. After the repair and testing are completed, you will receive a pro forma invoice from us for payment. Upon receipt of payment or upon receiving a bank confirmation of payment, we will dispatch the courier shipment.

Will I know the cause of damage to the controller that I will send?

Yes, in most cases we determine what the causes of damage to the electronics of the controller may be.

The most common causes of damage:

1. Normal operation – most electronic components have a manufacturer-specified service life. Components are subject to the aging process and their performance deteriorates over time. So, even in the case of gates that perform only a few cycles per year, but have a permanently connected power supply to the controller, after a few years they can fail.
2. Overvoltage in the power supply – it happens that a very strong overvoltage will cause damage to the controller, but it is often the “last nail in the coffin” due to operational wear and tear, as described in the first point. The overvoltage, therefore, accelerates the process of natural damage to the controller and its effects are not necessarily visible. A strong overvoltage leaves the typical damage of this type of failure. In this case, at the request of the Principal, we issue a certificate of diagnostics allowing you to apply to the Insurer for reimbursement of repair costs (if you have insurance for the facility against surges).
3. Wear / wear out of the gate drive – each drive has a manufacturer’s specified service life. Depending on the operating conditions, after 400-500 thousand cycles in the gate drive is already accumulated so many filings of worn bearings that at some point there is a buildup of filings resulting in a sudden stop of the gearbox, resulting in damage to the electronics of the controller. In this case, the most important power circuit responsible for controlling the operation of the drive is damaged. In this situation, in order to preserve the warranty for the repair of the controller, it is necessary to regenerate the drive.
4. Short circuit on control circuits / misconnection of external devices – unprofessional actions inside the controller can cause permanent damage to the electronics and disqualify the controller from repair. Short-circuit on the control circuits or given too high a voltage most often causes damage to the microprocessor and microcontroller, which, along with their software, are not available on the market and are therefore not replaceable. In such situations, we offer the sale of another, already remanufactured controller, which we program for a specific gate and assist remotely in commissioning.
5. Aggressive operating conditions of the device – several percent of damage to controllers is caused by too high humidity or air temperature during operation. The effects of moisture influence are visible in the form of snow and degradation of PCBs and SMD components. After verification of the state of the control by technicians and finding such an abnormality, you will always receive a notice from us to check the tightness of the housing and take measures to prevent a recurrence of the failure. In turn, too high operating temperature significantly accelerates the natural wear described in the first point.

How long does the repair take? When will I receive the controller back?

The estimated repair time – from the moment we receive the package until we send the invoice for the repair – is a few business days. This depends on the number of devices reaching our company. However, we make every effort to expand our technical infrastructure and our team as the number of service orders increases.

Upon receiving confirmation of the transfer or upon receipt of payment, we arrange for a courier to collect the repaired device.
