Need Help!- bridgeport with 151

[bbrreid]

Bridgeport Interact 1 mark2 Heidenhain 151B control
When I try to run a program or start the spindle I get the message "MACHINE GUARD OPEN " . the problem is , there are no machine guards on the machine, is there a machine parameter for this or maybe a faulty contactor/ relay.

Thanks to anyone who can help
getting desperate

It is seldom I can answer a question but here is the info to change the door interlock parameter:

MP4310.0 change from 0 to 1 not fitted gaurd door

Good luck and maybe you can help on the question I have,
Brian

First of all a BIG thankyou to everyone who replied
I found the original parameter list and can now reveal the fix.
I had been playing around with the parameters trying to fix a problem (which I still have ) with the uploading of programs from PC to machine.but not with downloading using Heidenhains program. so parameter 158 had been changed from a "1" to a "0" I changed it back to a "1" and all is well.
I hope this helps if it ever happens to someone else.
BTW MP92 changes language. MP 77 changes RAM to EPROM "1"
Regards
Brian
