Setting Pump Stall Threshold Values – Static Method
Use the following values for reference when using the Static method to adjust the pump stall
threshold values:
Low Speed High Speed
Vacuum ≤ -2.5in Hg ≤ -9.6 in Hg
Flow rate >200 cc/min >400 cc/min
Idle (I) 100 to 200 counts 150 to 250 counts
Block (Block-Idle) > 100 counts (Block-idle) > 100 counts
Stall Setting (Idle + Block)/2 (Idle + Block)/2
Stall High Threshold Setting – Static Method
In Diagnostic Mode, press the [MODE] key repeatedly until the “Pump” screen is displayed.
“High” should be highlighted. Otherwise, press [Y/+] to select the “High” value.
l The Idle value (shown as a value for “I”) should be 150 to 250. Record the value.
l Block the inlet, and record the value after it goes up.
l The blocked value minus the Idle (Unblocked) value should be greater than 100 counts:
(Blocked value – Unblocked value) > 100.
l If it is greater than 100, then the pump is working correctly and tubing leading from the
inlet is not leaking.
