Hardware problems

About this topic

This topic lists possible hardware problems, the causes of the problems, 
and ways to resolve the problems. If you are still experiencing problems 
with the BenchCel Workstation after trying the solutions, contact 
Velocity11 Technical Support.

Hardware problems

Problem

Cause

Solution

The BenchCel device 
does not turn on.

Your lab does not meet the 
electrical requirements.

Make sure your lab meets the 
electrical requirements. See “Verifying 
laboratory requirements” on page 29.

The BenchCel device is not 
connected to the power source.

Connect the BenchCel device to the 
power source. See “Connecting the 
power source” on page 39.

The fuse is blown.

Contact Velocity11 Technical Support.

A hissing sound can be 
heard.

A leak is present in the air 
connection or inside the device.

Check the air connections at the back 
of the device and at the source 
(house, cylinder, or pump). 

If the connections look fine, the leak 
is might be inside the device. Contact 
Velocity11 Technical Support.

Oil is present in the 
stacker head.

The compressed air is not from an 
oil-free compressor and oil has 
leaked into the BenchCel device.

Contact Velocity11 Technical Support.

The microplate drops 
from the robot 
grippers.

The labware definition for the 
microplate type might contain 
incorrect information.

Check the following in the labware 
definition: stacker gripper offset, 
robot gripper offset, stacking 
thickness, plate thickness, sensor 
intensity, and the plate-presence 
threshold.

To check or correct these values, 
open BenchCel Diagnostics and click 
the Labware tab.

Note:

 In the Plate offsets (mm) area, 

type 8 in the Robot gripper offset and 
the Stacker gripper offset boxes. 8 mm 
is the recommended offset for most 
labware.

If the problem persists, contact 
Velocity11 Technical Support.

The microplate drops 
or is held loosely by 
the stacker grippers.

The stacker gripper pressure is too 
low so that the grippers are holding 
the microplate too loosely.

Increase the stacker gripper pressure. 
See “Adjusting the stacker gripper 
pressure” on page 131.
