Polar 92 EM

Anybody know what Error 94 means

 

Hi sir:

Error 94:

Knife Running time upper dead pt/lower dead-and lower dead-pt./ upper dead-pt. exceed

Check:hydraulic circuit P2 valve y330+card HK

Blessing

 

Thank you. Now I know what Error refers to I will fix it

 

ok, sir

 

We have a Polar EM 92 with the Microcut JR with H3 Drive. We keep getting the code 184(B8) on our system (Zero set missing after Calibration). We have recalibrated the machine numerous times but keep getting this code. Any tips on how to resolve issue?

 

Hi sir;

Please review ,sensor b8 ;Shaft encoder zero set missing after position sense tripped on start up, possible lack of voltage in sensor +12Vdc, or the voltage out of tolerance 0.7% up or down., or loose cables, corrded, connector faulty, or dirty, or faulty, or sensor shaft encoder Defective

2) Look for the sensor b6 too position sense error, look with the similar conditions, or sensor defective

 

Hi. This means when position sensor tripped microcut is not seeing zero pulse from encoder.check LED 22 ON H3 drive see if it lights when rear position reached. If not disconnect encoder chain and move encoder until led lights. If Led does not light encoder defective

 

Remember;

Review status of power supply for;+1=+5Vdc 2) +12Vdc, if one of them are missing or out of tolerance, sensors will NOT work well.
However including if the Leds are ON, does NOT mean the Voltage is O.K, example, the LED can be ON, but if you measure +5Vdc, and get 5.3Vdc, is faulty, must be replace the power supply.
