After Sales and Technical
Keeping our installations operating exactly as they should is very important to us, even if you are not the original purchaser we will do everything possible to ensure the minimum inconvenience in the unlikely event of a repair being needed. Almost every part we have ever supplied is still available from stock.
We offer three methods of assistance.
1. Our engineer can call, normally same day or next day, our charge is a flat £112.50 for a 2 hour engineer visit. This is usually enough in 95% of call outs. Should further work be required, ther is a charge of £56.25/hr. Mileage is charged at £0.63/mile.
2. Customers who prefer to use their own electrician are well catered for. We stock all the parts and will give all the advice needed to enable a repair to be made.
3. For many, it is frustrating having to call others out at all to carry out a simple task when they are perfectly capable of doing the job themselves but lack the required information. Some of our competitors rely on the profit from ongoing service work and are understandably reluctanct to divulge information. Here at Scroll we offer full telephone support, will fax data sheets, wiring diagrams etc. will guide you through all the stages our engineer would go through on site and of course provide megabytes of information right here, all at no cost.
All systems fitted within the last 5 years by Scroll are essentially maintenance free, however checking and lubricating every once in a while does no harm.
Although we do not condone total neglect, we would not recommend constantly disturbing the equipment if it works properly. One exception is the manual release, which should be exersiced every few months to make sure it has not seized or been damaged. In the event of a power cut, if the key release has not been used for many years, it may not release easily.
Before servicing, turn the power off and release with the emergency release key.
All Scroll Gates's customers are left with a technical file fully describing the system, if this has been lost or mislaid, try our data sheet section. The information in the Engineers Servicing Notes section comes from actual 'hands on' experience and is not taken from any manufactures data.
With a properly designed and installed system whether by Scroll or anyone else, faults, thankfully are rare. The large manufactures, CAME (claim to be the largest in Europe), FAAC, & BFT have been manufacturing for so long that persistent problems have been ironed out. Dozens of lesser known companies are now exporting to this country as the market here grows and although prices can be very competitive, Scroll Gates's policy is to only use products with a proven track record.
Information in this section assumes the system is no longer under warranty and that it has in the past worked perfectly, also that you have a simple test meter and electrical tools, and are fully competent in using them, if not, we suggest calling out an Engineer. Always switch the power off when working with mains voltages. The information is given in good faith but we accept no responsibility for damage or injury as a result of any errors.
Note: Some control boards have a diagnostics output where the board will sense any errors in wiring, motors or a fault on the board itself and shut down. We do not supply boards with this facilty. If you have one and are looking at this section to trace a fault, we suggest calling in a service company that stocks all the spares for your make rather than attempting a repair yourself. The problem is that wherever the fault is, on the board itself or with a motor or the wiring between, the board will completely shut down, you will never be able to use a test meter to see which outputs are correct and which are not as they will all be 0, the only practical way to trouble shoot is to selectively replace parts until the system works again.
Fault Finding FAQ
1. Nothing Works!
2. RCD breaker trips whenever the gates are moved
3. Only one side works or one gate only moves one way
4. A loop detector occasionally fails to open the gates
5. A radio transmitter fails to work or works erratically
6. Digital keypad fails to work
7. The gates open but do not close
8. Odd things happen!
Items in red text refer specifically to CAME equipment, for others, refer to the manufactures data.
Always Isolate the power before performing investigations.
Check fuses and earth trip, and that 240v is present
Using the manual release system open the gates about halfway and relock. Try the gates again, this determines whether or not you have lost both opening and closing phases. To make sure, link the actual terminals on the circuit board to give a definite opening command and a definite closing command, link 1 to 3 to open, link 1 to 4 to close, if nothing, check for 24v between terminals 0 & 1, if no 24v there is probably a problem with the transformer or a fuse blown, if there is 24v, remove the wires running to the command input terminal 3,4,7, try again, if it works selectively replace the input wires until it fails, thus identifying which command has failed, if nothing happens, the board is probably faulty.
RCD breaker trips whenever the gates are moved
Most likely cause is water. Check all obvious places, junction boxes etc. remove the cables from the board to one operator, X,Y, try again, if it still trips replace and try the other operator U, V, once you have determined which one is causing the problem check that one more thoroughly, if there are joins in the cable, selectively disconnect them to determine exactly where the fault lies.
Only one side works or one gate only moves one way
Either a problem with a relay or a failed operator. If only one side works, swop the operator wires from one side X & Y with those on the other side U & V, this will determine whether the operator or the board is at fault.
A loop detector occasionally fails to open the gates
Check cabling and joins, try altering the frequency or adjusting the sensitivity up or down. Occasionally if the board is near other boards some interference can stop them working, if need be, house the board in a separate enclosure. If the problem persists, change the board.
A radio transmitter fails to work or works erratically
Most likely problem is the battery, otherwise check the code and channel select are the same as the receiver, on CAME TOP series, if the transmitter is dropped repeatedly, the ferrite aerial can become detached, if it rattles, its detached, return to Scroll for repair (normally £10.00).
Digital keypad fails to work
In most systems, entering an incorrect code more than 3 or 4 times will shut down the unit. Check the inside of the keypad which can become full of insects especially woodlice, there can be so many that the tiny circuit components working with a just a few milliamps are effectively shorted out. Clean out and carefully spray with WD40 to reduce any condensation problem. Occasionally an individual switch will fail, try entering another code. If a switch fails, it will probably not do so completely but will give a slight electrical resistance, use a multi-meter on the actual solder tags of the most used switches, the resistance should be nil. We can solder new switches on but normally replace the unit.
The gates open but do not close
Could be a problem with the circuit board but its unlikely, its normally either an input staying on or a safety circuit staying off. To check the latter, bypass all the safety equipment by linking the normally closed terminals, 1,2,C1,C2,C3, try again, if OK check any hardware wired to these terminals, photo-cells for example. If linking makes no difference, switch the power off then on again, open the gates, wait until they definitely should be closing, listen to the relays and remove selectively all the command wires, radio, push button etc. On CAME ZA2, remove all wires from terminal 3 then 7, if a relay clicks, and the gates close, one opening device is giving a constant signal, for example a push button might be stuck in or the entry phone relay might be failed on, determine which device is giving a constant open signal and rectify the problem. If the gates still fail to close, change the board.
Odd things happen
Control boards are essentially digital devices, they rely on their inputs being either totally open circuit normally 24v or shorted completely to ground, normally 0v, unusual and unpredictable things can happen when an input is somewhere between the two. If you have a really odd fault, its best to use a multi-meter to establish whether or not the hardware is giving good results.
