Service personnel must read and understand the OPERATING INSTRUCTIONS ‒especially the
“INSPECTIONS AND TESTS” and “MAINTENANCE” sections ‒before servicing the vacuum lifter.
Many of the following discussions assume knowledge of the OPERATING INSTRUCTIONS.
Note: Wiring and/or hose-routing diagrams are provided in the final section of this SERVICE
MANUAL for reference when servicing or troubleshooting the lifter.
SERVICE SCHEDULE
Service must be performed whenever a deficiency is indicated by routine inspections or tests.
Follow the “INSPECTIONS AND TESTS” section of the OPERATING INSTRUCTIONS. Any service
warranted must be performed before resuming normal operation of the lifter.

Rev 2.0/4-20 DC3 DVS, Powered Motion: #3610813
TOCHANGE THE VACUUM DETECTION THRESHOLD
As a precaution, the lifter will activate the “attach” mode if vacuum is detected under unusual
conditions (see Codes N00, N01 and N02 in “INTELLI-GRIP®DIAGNOSTIC CODES” on page 6 and
page 7). To adjust the sensitivity of this feature, follow these steps:
1) Access the Operator Menu and select “Lifter Settings”, as previously directed.
2) In the Lifter Settings menu, select “Vacuum Detection”.
3) In the Vacuum Detection Threshold menu, select the desired sensitivity threshold.
This setting can only be changed using this menu. It will not reset automatically when
the lifter is powered down.
TOCHANGE THE LEAK RATE THRESHOLD
The lifter will alert the operator if vacuum decreases more quickly than expected (see
Diagnostic Codes V011, V012, V013, V014 and V015 in “INTELLI-GRIP®DIAGNOSTIC CODES” on
page 9). With rough or porous loads, this can result in frequent or constant alarms. To adjust
the sensitivity of this feature, follow these steps:
1) Access the Operator Menu and select “Lifter Settings”, as previously directed.
2) In the Lifter Settings menu, select “Leak Rate Threshold”.
INTELLI-GRIP®OPERATOR MENUS

TOCALIBRATE THE LOAD SCALE
Occasionally, the load scale may require recalibration to prevent inaccurate readings. Any of
the following may indicate this need:
• The Total Weight deviates significantly from 0 when the lifter is set down and fully
supported, and there is slack in the lift cable;
• The lifter weight measured by the load scale does not correspond with the Lifter Weight
shown in the “SPECIFICATIONS” section of the OPERATING INSTRUCTIONS;
• The load weight measured by the load scale does not correspond with its known weight.
1) Access the Load Scale
menu as previously
directed and select
“Calibrate”.
2) Make sure the lifter is set
down and the hoisting
equipment is not
supporting any weight. In
the Calibrate menu, select
“Zero Weight”.
3) If a load with a known
weight is available, select
“Attach To Load” from the
Calibrate menu and
attach the lifter to the
load as directed in the
OPERATING INSTRUCTIONS.
If a load of known weight is not available, skip to step 4.1
4) Lift the lifter (and load, if attached) and make sure they are freely suspended. Then
select “Set Known Weight” from the Calibrate menu.
1..... The lifter weight can be used by itself, but the calibration will be more accurate if the total weight is closer to the lifter weight plus its maximum
capacity.

5) Enter the known weight by moving the cursor with the “attach” button ( ) or the
“release” button ( ), and change the value of each digit by using the “function” button

completed with
inaccurate information.

directed in the OPERATING INSTRUCTIONS. Make sure to suspend the lifter freely, along
with any removable equipment, before selecting “Set Lifter Weight”.

TOCONTROL POWERED MOTIONS
The radio controls are normally used to control powered motions, allowing operators to
position themselves safely with regard to load movement and potential falling hazards.
However, lifter motions can be controlled through the Operator Menu, when necessary for
troubleshooting and emergency situations.
1) Access the Operator
Menu and select “Motion
Controls”, as previously
directed.
2) Select the kind of motion
you want to control, such
as the “Counter-
Balancer”. Note that the
“[Yes]” designation for
the optional Counter-
Balancer indicates that it
is installed and active.
3) In the Counter-Balancer
menu, select the motion
that you want to perform
(ie, "Retract
Counterweight", “Extend Counterweight”). To engage the motion, press and hold the
“function” button ( ).
Note: All motion menus work similarly.
