EMERGENCY!! need dip switch settings for tool changer

-=PAB=- · Post by **-=PAB=-** » Sun 17 Sep , 2006 10:51 am

i have stupidly accidentaly knocked the dip switches

for the tool changer- it is for a TRIAC ATC 1990 PNC3 control. the switches are ranked 1-8 if anyone could tell me the correct settings that would be great... cheers...

Hi PAB...

Are these the DIP switches on the PCB in the small electrical enclosure mounted on the back of the machine?

Mr Magoo · Post by **Mr Magoo** » Sun 17 Sep , 2006 11:33 am

I haven't managed to find any info on the toolchanger board used in the Triac, but it was a special variant of the North East Electronics SMCU controller that talked to the main Triac controller through it's own special serial link.

Here is an extract from the manual I found on their website regarding the DIP switches on the SMCU (may or may not relate to the variant that controls the toolchanger

)
NOTE the LED it mentions is located on the PCB in the rear electrical cabinet, not the front panel - I think the "few shot flashes then off for a while" error indicators are valid, not sure about the other stuff about the LED though

http://www.nee-controls.com/legacy_downloads.html

Page - 37
Indicated System Errors
The unit includes a front panel indicator which has a number of uses.
At initial power up if the controller microprocessor is running and the EPROM checksum is correct the indicator
repeatedly flashes On for ¼ second, Off for ¼ second until the first RS232 command is received (if RS232 operation
selected by SW 7) or until the optional keypad is used (SW 7 Off). If at power up the EPROM checksum is
incorrect the indicator flashes On and Off 5 times a second.
If the controller is operating in RS232 mode (SW - 7 On) the indicator changes from On to Off or vice-versa for
each RS232 character received. In normal operation controlled by a host computer the indicator will glow dimly as
RS232 characters are received then will remain Off or On for the period between receipt of characters. Any error
conditions detected by the controller are transmitted to the host in a coded form (see section b).
If the controller is not operating in RS232 mode the initial flashing stops when the keyboard is operated. The
indicator then changes from On to Off or vice-versa each time the keyboard is operated.
Whilst the controller is executing a Dwell the indicator increases then decreases intensity once per second.
Whilst the controller is executing a Wait Until Input command the indicator flashes rapidly.

The indicator is also used to indicate a number of error conditions as follows:-

Error Indicator Operation

Overtravel Error 1 short flash on then off for 2.5 seconds repeated.

Stepper Drive Fault 2 short flashes on then off for 2.5 seconds repeated.

Datum 3 short flashes on then off for 2.5 seconds repeated.

Ext Stop pressed 4 short flashes on then off for 2.5 seconds repeated.

ROM RAM Data Error 5 short flashes on then off for 2.5 seconds repeated.

Command Error 6 short flashes on then off for 2.5 seconds repeated.

When the MC3E, (SMCU/SMCU+ version 007 onwards) is switched on the RS232 interface operates at 300 baud,
7 data bits and odd parity. Systems connected to a host computer should be initialised at this time with data from
the host. If the host computer does not operate at 300 baud, 7 data bits and odd parity the controller will indicate a
command error.

If the controller indicates a data error at power up the internally stored system parameters will have been corrupted;

the system must then be connected to the host computer and correctly initialised before use.

Setting of Internal Assign Switches and Links

The unit has internal switches which enable the unit to be set to operate in a number of different modes at initial
power on after the external ram has been cleared or after an external ram checksum error has been detected.
8 switches only are fitted, their function is as follows:-
SW 8 – Hardware Test Mode Select

If SW8 set On at Power Up SW4 to 1 are used as follows:-
SW4 SW3 SW2 SW1
Off Off Off Off - Not Used
Off Off Off On - Not Used
Off Off On Off - Read/Transmit status of Datums/Inputs
Off Off On On - Read/Transmit status of Overtravels/Link 1, 2
Off On Off Off - Read/Transmit status of Assign Switches
Off On Off On - Read/Transmit status of Ext. Keypad
Off On On Off - Read/Transmit status of Ext. Stop Drive Flts
Off On On On - Sequence Aux 1 to 4 and Spdl relays/LED
On Off Off Off - Execute Auto Test
On Off Off On - Do a 3 axis move
On Off On Off - Ramp D to A output
On Off On On - Checksum ROM and transmit checksum
On On Off Off - Test External RAM (if fitted)
On On Off On - Read/Transmit status of inputs 5 to 12
On On On Off - Sequence Aux 5 to 12
On On On On - Sequence Aux 13 to 20

If SW8 is Off:-
SW7 selects RS232 data transmission from controller if On
SW6 selects either ROM (if On) or RAM program execution from keypad
SW5 selects continuous program execution (if On) or wait for Start between program executions if Off.
On systems with battery backed RAM SW4 to 1 are not used.
On systems without battery backed RAM SW4 to 1 are used as follows:
SW4 selects parity checking of input RS232 data if ON
SW3 selects either Odd (if On) or Even parity for received and transmitted RS232 data
SW2 & SW1 select RS232 baud rate as follows:-
SW2 SW1 Baud Rate
Off Off 300
Off On 1200
On Off 4800
On On 9600

Use of PCB links:
Link 1 fitted for 11Mhz Xtal, remove for 14.756Mhz systems
Link 2 fitted on SMCU, remove on SMCU+

thanks for finding all that - much appreciated- will try and make sense of all that.. unfortunately the dip switch settings as they are at the moment have effected the tool changer so it no longer works..TOOL CHANGER ERROR!!!!

If anyone has the same machine (TRIAC 1990 ATC) i would like to try their settings for the dip switches and hopefully they would work???

cheers everyone...

-=PAB=- · Post by **-=PAB=-** » Tue 19 Sep , 2006 0:07 am

the dip switches in the rear electrical box under the external monitor only seem to effect the tool changer- its these i need to reset.. the info you gave me does not sort the problem out- i could do with the factory default settings or someone who has the same machine to let me know their configaration..

thanks for any help......

Is the red LED on the toolcange control board flashing at all?

If so, what is it's ratio of on to off times (see my previous post re: status LED)

The toolcanger board contains some batter-backed RAM in order to 'remember' which tool is in the spindle when the machine is switched off. I think this memory may be corrupt.

-=PAB=- · Post by **-=PAB=-** » Tue 19 Sep , 2006 13:29 pm

red light flashes continously with no breaks or pauses. everything worked ok till i knocked the switches- could this have corrupted the memory?? any way to reset?? the machine does not remember the tool in the spindle- it asks after datuming..

Mr Magoo · Post by **Mr Magoo** » Tue 19 Sep , 2006 21:33 pm

flashing LED sounds like the pcb is healthy (i was confusing triac atc with starmill re battery backed ram)

i have had another look around for info but have none. i hope someone out there can reply who has a similar unit.

just a thought... are the cables between machine and atc control box all seated ok?

-=PAB=- · Post by **-=PAB=-** » Tue 19 Sep , 2006 23:37 pm

yeah all cables are ok - i've just gotta get that switch config right and all will be ok.. thanks for all help..

RIP steve... will be greatly missed!!

Hello!

Have you already tried the order "M27 reset Carousel"?
This assigns the current tool to tool 1.
You have for certain this, wanted to enquire only.

Greetings

Enny

cant get to the point of inserting m code and im sure this wont reset the dip switches.. thanks anyway..

this might be over the top, but if its causing you major headaches - then you are guarenteed to get it right within 4.2 hours, assuming a startup time of 50 seconds, and 10 seconds to change the dips.

good ol' binary

00000001
00000010
00000011
00000100
00000101
00000110
00000111
00001000
...
well you get the idea

0=off or up or whatever
1=down or on or whatever

and once you've found them, write it down, and mabey post it here so that it is forever more stored in the depths of google.

good luck mate

I also do not believe the dip switch be put again into its starting point by it.
My machine dates from 1991 and have an ATC fitted. I can't find the switches described by you, have a photo?
Another idea would be deactivating the ATC in the .opt file, completely start machine once, after some time activate the atc again. This also will not put the dip switch into their starting points, accumulators provide with new tension, possibly however.

-=PAB=- · Post by **-=PAB=-** » Sun 24 Sep , 2006 19:13 pm

the dip switches are located in the rear electrical box fitted to the inside of the door. the switch housing is blue and they are ranked 1-8 - 1 being at the top.. note pics below..

cheers...

Martin · Post by **Martin** » Sun 24 Sep , 2006 20:24 pm

I think that some of these replys relate to other Control types that Denford fitted.

The M27 only works on the later machines.

The machine Pab has is fitted with a NEE PNC3 control system.

I am sure that when we powered one up that we only had to set the Dip switches in order to set it up.

The toolchanger then Datums automatically after all the axis have moved datumed.

I have tried to find the original info but have not been able to locate it.

I think it is worth trying the switches as sugested above. I am sure that it will not be a long process.

Good luck.

As Martin already said.
My machine seems to have another control. The DOS computer of the control is mounted at the back of the electrical box door.
I am sorry I could not help you.
Much luck with the solution of the problem .

If you had started doing it by the numbers, when you posted up the picture, youd have it sorted by now

-=PAB=- · Post by **-=PAB=-** » Mon 25 Sep , 2006 18:09 pm

unfortunately i have to work long ours and dont get much time to work on the machine very much- if anyone nows a quick way of producing all the possibilities and would post them here i would be most greatfull.

cheers..

Hi

Have you tried contacting NEE ? www.nee-controls.com

They have a manual for the PNC4 controller on their website, but many years ago I got a PNC3 manual from their website in the form of a PDF. I've probably still got it somewhere at home - god knows where. Might be worth trying them first - I will have a look and see what I can find at home.

Cheers

Dave
