Fault diagnosticsBC Fault Possible cause What to do1 Differences between the channels - Only one Channel detect an Error Look at the error code of the otherchannel2 One of the channels does not work - One channel defect Reset3 Feedback circuit open - Normally closed contacts ofexpansion relays are not wired Check wiring- Bridge not wired4 Start button constantly activated - Start button defect- Start switch is used instead ofstart button5 Key switch is activated during starting - Key switch activated- Key switch defect Reset6 BWS Empfänger aktiv bei Start - Wiring error of the light barrier7 Internal fault of the safety output - Wiring error of safety outputs- Disturbances on the access line- Output defect8 Internal fault of light barrier senderoutput- Wiring error of safety light barrier- Disturbances on the access line- Output defect9 Muting lamp disconnected - Muting lamp defect- Muting lamp is missing- No bridge by application as controllerfor light barriers10 Two starts with key switch - After the clearance of the lightbarrier the key switch was activateda second time11 Light barrier disconnected during startor time out on light barrier receiver12 Simultaneousness of muting sensorsexceeded (3s)- Wiring error of safety light barrier- Optical Path is broken- Timeout reached- Wrong position of the mutingsensors- Only one muting sensor wasactivated13 Internal fault of muting lamp control - Wiring error of the muting lamp- Muting lamp defect- terminal 53 is connected to GND- Output defect Check expansion relays Check start button on short circuit Check start button (must be a button) Check key switchCheck wiring; light barrier must activatedwith output 63Check wiring of safety outputs, payattention to wiring advice!Check wiring of output 63, BWSE+,pay attention to wiring advice!Check muting lamp and change ifneccessary Reset Check wiring Check optical pathCheck technical data of the light barrier(start time, power consumption)Reduce current consumption withadditional relayCheck position of muting sensors, thematerial must activate both sensorswithin 3s all muting sensors wired ?Check wiring at terminal 53 and ESS+Check muting lamp14 Muting time with key switch exceeded - Manual muting timeout (10 min)reached Reset15 Internal memory fault - Disturbances on the access line- Internal error Reset; if BC comes again: check systemon disturbancesRS-NAGU.2f - 270912 15/16
