“Vacuum decrease on circuit #”
(# indicates relevant vacuum
circuit)
3 chirps
(none)
Vacuum decreased at greater rate than expected in
circuit(s) indicated. Possible causes include bouncing or
landing load, as well as use on rough or porous loads and
other sources of vacuum leaks. Consult relevant topics in
“ASSEMBLY”, “OPERATION”, “INSPECTIONS AND TESTS”,
and “MAINTENANCE” to eliminate leaks when possible.
When appropriate, you can also adjust sensitivity to
vacuum level reductions (see “INTELLI-GRIP

“Vacuum not increasing
normally”
1 chirp every
2 seconds
on
Although lifter began to attach, vacuum level did not
increase at normal rate. Make sure all vacuum pads seal
securely (see “Sealing the Pads on the Load” on page 19
and “Reading the Vacuum Gauges” on page 20). This Code
can be activated by use at high elevation. If so, contact
WPG for directions.
V03A
V03B
“Pump running excessively”
1 chirp every
2 seconds
(none)
Vacuum pump is running more often than normal. Likely
causes include significant vacuum leak or difficulty
achieving minimum vacuum level due to high elevation.
In case of suspected leak, check for fault(s) in vacuum
system. See relevant topics in “ASSEMBLY,” “OPERATION”
“INSPECTIONS AND TESTS”, and “MAINTENANCE”.
In case of high elevation, contact WPG for directions.
V040
“Lockout (vacuum sensor error)”
continuous
(none)
Once “Power Save” mode is activated, “attach” and
“release” functions are prevented due to a vacuum sensor
malfunction. Make sure sensor connectors are correctly
plugged into circuit board.
V050
“DANGER! INSUFFICIENT
VACUUM!”
continuous
on
Vacuum levels in BOTH circuits are insufficient for lifting.
Keep everyone away from suspended load until it can be
safely lowered to a stable support.
Service is required.
