Hello eveyone,
I have a VKRC1 (with ONLY T1 and Ext. Aut. modes on its pendant). It all seems to be ok at T1, but I get the following error when I switch to Ext Aut.
"Opearot Safety / Gate Open"
Here is the XS2 plug wiring.
A1 - A3 - B1 - For ext. emgr. 24V
A2 - B2 - Ext. emgr. relay channel 1
A4 - B3 - Ext. emgr. relay channel 2
B4 - B5 - Safeguard channel 1
B6 - B12 - Safeguard channel 2
B7 - B8 - B9 - T1 Operation mode
(No connections for A5 and A6 / Interbus, there is a board for interbus but we will not be using)
I have attached the connections and the circuit diagram under CIRCUIT.JPG
Additional Info----------------
Wether im at T1 or Ext, on the safety circuit board, none of the relays change status when I disconnect B4 or B6 (safeguard). As far as I understand, It is supposed to release a relay, like when I disconnet an emgr. jumper (it releases R1 and R4 from the image SAFETY_BOARD).
In case it provides any clue, here is the relay reactions at manual and ext. auto modes (relay numbers are marked on the attachment SAFETY_BOARD):
Manual mode (dead-man not active, drivers are off):
R1: ON R2: OFF R3:OFF R4:ON
R5:ON R2:OFF R3 OFF R4:ON
Ext. Auto mode:
R1: ON R2: OFF R3:OFF R4:ON
R5:ON R2:OFF R3 OFF R4:ON
----------------------------------------
The connections seems to be OK, I have the right readings for 24V at the shown pins on the circuit diagram (CIRCUIT.JPG). I cant figure out what the problem might be. Anyone have any clue ?
Do i need to do something other then sending CONF_MESS, DRIVES_ON, DRIVES_OFF (always high) and EXT_START. Or is it more likely some kind of an electrical problem?
Thanks in advance,
