polar 76 em error code 86

Hi Qure,

Hope this can help you out there.

--86-- meaning:

A static discrepancy does exist between the output of both cutting circuit channels (hardware channel and positioning computer ) LED V2 and V3 KK are lit up permanently.

--86-- Remedy:

Check voltage + 42 V on plug CU 9.2 (safety bolt)

Check basic conditions of LED’s V14 - V18 HK.
If one of these LED’s is lit up:
Exchange card HK

Check basic condition of LED’s Vl - V3, VI9 and V23 IAR.
If the basic condition is not in agreement as :
LED V1 OFF Cut buttons activated with in 0.5 sec.
LED V2 OFF Lightbarrier monitor test completed
LED V3 ON Safety bolt not activated
LED V19 OFF + 24 Volt on transformer CU.T2 - clamping -
LED V23 OFF + 24 Volt on transformer CU.Tl - cut -
Exchange card IAR

Check connection AR - IAR (flat wireharness)
Exchange card AR
Exchange card KK

Hi sir the error code 87 :

Please test continuity with a DMM( Digital multimeter) the cut button s28a+s28b according with the wiring diagrams, for the contacts N.O and N.C, see if there clean , loose cable, or microswitch inside faulty, or broken wires, repair or replace.

2) test the flat cable between -AR vs IAR( hardness).

3) Exchange Card AR or IAR or both.

Let me know.

Sorry sir:

I did a mistake did believe that your error was 87 and is 86;
do this;

1) check voltage +42Vdc in plug CU9.2 (safety bolt)

2)Check basic conditions of LED’s V14
- V18 HK. If one
of these LED’s is lit up: Exchange the card HK

3) Check basic condition of LED’s Vl -
V3, VI9 and V23 IAR.

V3= On if safety bolt NOT activated
V1= OFF cut buttons activated in 0..5 seg
V19=OFF +24Vdc in transformer CU.T2 clamping.
V23 =OFF +24vDC in transformer CU.T1 cut


Let me know.

Our 76 em suddenly stopped displaying numbers (red analog ), we had 2 different techs and one says I have to replace 3 PCB Board, the other I need a complete new Board for the Display.

I'm at a loss, what is right.?
 
Hi sir:
