Reccomendation for Roller shutter Controller

[Cyberprog]

Hi All,
I'm a Network/Software consultant, but I also do Access Control, and consult on basically anything else electrical! Run into a fun one at a clients, they have a 3-phase roller shutter which seems to be controlled (having had a peek into the box) by a pair of contactors with an overload between them. As near as I can tell, the motor is doing it's own limit stuff (there appears to be a limit switch in the wiring, but it's hanging to one side with the switch taped closed!) but they're not able to secure the unit from being operated that easily as it's just contactors. They'd also like to be able to tag the net2 and control the door from outside (which doesn't have a rear door, and it's a bit of a trek round the back!). I've seen various roller shutter controllers on eBlag, but none are three phase, and my usual friendly sparks has never installed anything like that, so can't reccomend one.
Has anyone had the pleasure? Client's a cheapskate (aren't they all?) so is after a cheap solution to the problem. I know these things exist, just haven't a scooby doo as to where to look, and most roller shutter companies want a service contract and half an arm and the full leg to install one as none of them are based locally (and all the local ones CBA to quote me!).
Any help would be appreciated!
Cheers
Alex.

if you change the starter over to a new starter most of them come with extra inputs to attach clean switching wires such as key switches. there are 2 companies i would recommend and that is link controls or ellard. the both have websites and are very helpful in the technical department. all you really need to know is wether the limits at the motor are 3 or 4 wires.

Maybe a silly suggestion, ....but have you not contacted the manufacturer?? Surely they will have various types of controllers for automatic operation suitable for your roller shutter....

IIRC I have tried to, can't find the details of the motor but it's quite an old warehouse & equally old motor!

it wont matter how old the motor is. If you are in doubt then change the motor as well.
but at the moment you just want a starter that will open the shutter with your fob system. If you want it secure then the only true way is an anti vandal paxton reader which you sink in the wall, and let your net 2 data base control the fobs with expire dates or deletion. get your client to get a deposit when issuing the fobs then he will get a few of them back. A lot of older companies are not around anymore.

Yep, that is indeed an option, but I'd prefer to put in a purpose built unit to take care of things, as that gives me the ability to go full auto on the door if we install some limit/safety bits.

Client is a cheapstake, so changing the motor is out of the window (if it's not broke, don't fix it!). I can persuade a new control box into them for the functionality they'll gain. To be honest, I'd not considered just changing the contactors for new ones, but this is certainly something we can look into, though a controller would be nice

You will only get a unit to operate the shutter. how you operate it is down to each individual needs, but generally the most common way is a key switch. you can flush mount them too. The companies i suggested will help you. if the shutter is to self close then a photo beam across the shutter and a safety edge is required. the timer is all built in.

both these will help you a lot.

Aha, the link controls mini basic/mini standard look like a good starting point, brilliant, thanks! Think I need to go get up a ladder and work out what the motor is rated at to work out which unit I need

 

[shiner]

mini standard is the one with all the functions you will need for the future.

 

[shiner]

if you go down the changing contactor route you will find it very hard to do anything with the shutter, apart from open or close. i really wouldn't recommend it. you will need relays to control the shutter as us will be switching voltages.

 

[Cyberprog]

Well that's all it does at present, but I know what you mean. I've emailed a few distributors regarding the mini standard, so lets see what sort of moolah they come back with for one!

 

[shiner]

go direct to link it should only be about £90. you can chat to technical first they will defiantly point you in the right direction. they take card payment i think and vary prompt on delivery.

Cool, that sort of money sounds great. Cheers
