Calibration
If some buttons of the Maintenance menu remain inactive after installation, switch off
the machine, close the door, turn the machine on and let it run automatic initialization.
After it stops making noise check if those buttons are activated.
This issue happens when PLC is new and it does not have the initial position values
written in. When machine initializes the values are being written into PLC. You will have
to do this once and they will stay in the memory.
Tap "Maintenance" → next page → "Advanced" (Password-1688).
Go to page "Teach position" and follow the steps below to calibrate.

━ X-Axis Calibration
1. Put the Tips (200 μ l) at the W4 in the positions 1 and 16 on the T-rack.
2. Run W4 piston test and observe the distance between real position and correct
position.
3. X position:
1 mm = 92 Pulse;
Direction: Inward (X axis moves inward, pistons will be outward) → minus;
Outward → plus.
For example: if you want to make the X axis position (T-rack) 1 mm inward, the original
value is 10000, 10000 – 92 = 9908, enter 9908.
Adjust the Input Pulse → tap "Enter" → tap "Upload Encoder Value" → tap "Execute",
repeat until the position is correct.

━ Y-Axis calibration
1. Put the Pipette Tips (1200 μ l) at the W3 at in the positions 1 and 16 on the T-rack.
2. Do W3 piston test and observe the distance between real position and correct
position.
3. Y position,
1 mm = 672 Pulse,
Direction: Upward → minus
Downward → plus
For example: if you want to make the Y position 0.5 mm downward, the original
value is 30000, 30000 + (672 x 0.5) = 30336, enter 30336.
Adjust the Input Pulse → tap "Enter" → tap "Upload Encoder Value" → tap "Execute,
repeat until the position is correct.
V-axis values are preset; they have to be rewritten to PLC only if a PLC unit was
replaced.
To see V value, press an arrow down in Teach position, you will see the screen for V-axis
motor. "Load default values" (1) and press "Execute", then "Upload V_200 Position" (2)
and press "Execute" and then "Upload Encoder Value" (3) and press "Execute":

Pistons
━ Noise during Pipetting
━ Cleaning Pistons
If you hear noise during pipetting, this means the grease on the pistons wore off.
Lubricate the rods inside the pistons.
If lubricating the piston does not help, replace the piston (you can send us pistons for
maintenance or install new ones).
1. Take out cartridge rack, move V axis to the lowest position manually or by JOG
mode.
2. Unscrew the screws on the metal sheet, and then detach the metal sheet.

3. There is a hole on the metal rod, fix the metal rod with a hex key, then unscrew the
upper screw.
4. Move the V axis to highest position manually or by JOG mode.

16 www.rbcbioscience.com
5. Take the piston out, you can pull out the metal rod and clean the inner side with a
cotton swab, but do not screw the cap and nut, and do not disassemble the piston,
or the tensile strength might be altered and lose accuracy.
6. Follow the reversed steps to install pistons, push the metal sheet inward gently and
fasten the screws, then do all axis initialization after the installation is finished.

If instrument is showing Error14 (V Position Over Pulse) and it is impossible to run jog
test for V-axis or move it manually, this indicates that the X-rings inside the pistons
have worn off.
Do not try to exchange X-rings – opening the piston will change its tensile strength
and pipetting will lose accuracy.
Replace the piston (you can send pistons for maintenance or install new ones).
