Part D: Troubleshooting - Peristaltic Pump Heads
When this occurs: Check the following: Possible solution
When “Check Pump Head” error
occurs with your peristaltic head.
1. Does “Check Pump Head” occur
with no tubing in the head?
2. Confirm the tubing sizes you are
using.
1. If it o
c
curs with no tubing in the
head, call Parker.
You may need
a new motor.
2. If no, make sure you are using the
correct size tubing. Thick walled
tubing in a thin wall pump head will
cause this, and may break the head.
When peristaltic pump head turns,
but no fluid flows.
1. Check the tubing size and pump
head type, as you may be using the
wrong size for that head.
2. Tubing Size is ok
1. 1081 is for thin walled
tubing, and 1082 is for thick-walled
tubing. Thin-walled tubing in a thick
walled head won’t produce much
flow. Use the correct size tubing.
2. The pump head may be cracked from
being forced closed with the tubing
crosswise or the wrong size tubing.
Contact Parker for repair or
replacement parts.
When the pump head turns ok with
no tubing installed, won’t turn when
you put tubing in, and you don’t get a
“Check Pump Head” error.
The coupler is loose or
broken.
Contact Parker for
technical
support, or to arrange for
service
and an RGA#.

shows on your screen.
1. Is your scale turned on, and are
the cables tight?
2. Ok, the scale is on, cables are ok,
and it still won’t work?
3. Ok, the scale is chosen correctly,
and it still doesn’t work.
Now what?
1. Press any ke
y

sc al e, a nd tr y i t a ga in .
2. Check Section 4, Setup: Scale of
this manual, then go to Setup

The aliquots are all wrong; it gets data
from the scale, but slows down
