MagCore® Plus II
13 V_Encoder no change
• No signal response from the Encoder.
1. Check PLC X00 terminal – make sure the cable (CBL-0031) is not loose.
2. Check if encoder is functioning properly.
3. Clean encoder disc.
4. Check encoder cap. Open it and see if the red LED inside is on. If the light is off Encoder needs to be
replaced.
5. Check encoder signal (CBL-M006) and power (CBL-M005) cables.
14 V_Position Over Pulse
• The position coordinate greatly differs from the Encoder coordinate.
• Pistons need to be cleaned, X-rings are aging.
1. Clean encoder disc.
2. Check PLC X00 terminal – make sure the cable (CBL-0031) is not loose .
3. Check motor cables( M005, M006) – if connections are loose or cables are damaged motor will
lose power and trigger an error.
4. Manually check if V-axis can move well. Switch the machine off and push/pull liquid handling
module. If it cannot be moved, pistons have to be cleaned and X-rings replaced.
5. Check if PCB/PLC is functioning properly.
15 V_Home Sensor Fail
• No response from V-Home sensor
1. Check PLC X00 terminal – make sure the cable (CBL-0031) is not loose.
2. Check motor connection to power, PCB and PLC.
3. Check encoder cable.
4. Check V home sensor cable (S003).
5. Check if the sensor works properly.
6. Check if motherboard is functioning properly.
16 X_SoftLimt+
• Encoder pulse count exceeds the value set by the software; the distance from the motor moving
forward does not match the distance from encoder.
1. Restart the instrument.
2. Clean encoder disc.
