Installation
Safety Precautions
Automation can be extremely hazardous.
There may be rapid, sudden motion anywhere
within the normal work area. It is mandatory
that power down and lock out procedures be
followed exactly. Guards and interlocks
must be fully operational and in place for all
normal operations.
• The greatest safety hazard in operating
and servicing automation is the
pinch/trap/crush potential. Never place
yourself in a position where you could be
trapped by the automation.
• All equipment is fully guarded and
interlocked for safe operation. Control
panels, disconnects and emergency stops
are located and identified for each of the
individual work stations. Check that all
interlocks, overloads (breakers), over-travels
(limits), and disconnects are fully operational.
• Read and understand all manuals, warning
plates, and labels on the automation
before operating or maintaining the
automation. Replace any worn labels.
• Check all warning lights on the console
before operating the automation. Contact
the maintenance supervisor if necessary.
• If possible, always lower lifts to the lowest
possible position, engage manual locking
pins, and exhaust all air out of the
counterbalance system.
• Disconnect and lock out all main electrical
power and turn off and bleed the air
supply lines before beginning repairs.
• Only trained, qualified, and authorized
personnel should operate, maintain, and
repair the automation.
• Always wear protective glasses and shoes
when working around the automation. Do
not wear jewelry or loose-fitting or torn
clothing when working on the automation.
• Never replace electrical components while the
automation’s main disconnect switch is on.
• Be sure that all replacement parts are
interchangeable with the original parts, and
are of equal quality to those provided with
the original equipment.
• Repairs requiring welding should only be
performed using the appropriate reference
information, and by personnel adequately
trained in welding procedures.
• Make sure all shields, clamps, and guards
are installed correctly.
• Do not operate the automation if any
part of the automation has sustained an
impact or collision.
• Support any sub-assemblies (such as
carriage plates, motors, cylinders, etc.)
that you are removing from the
automated equipment.
• To avoid injury, use a hoist when lifting
components weighing 50 lbs. (23 kg) or more.
• Modifications and additions which affect
capacity and operation of the automation
should not be performed by the customer
or user without the manufacturer’s prior
written approval. Modifying the automation
may cause personal injury and may void
the warranty.
• Make sure all personnel are clear of the
automation area before operating
the automation.

Operating and Set-Up Specifications
• Fluid: Compressed Air
Note: Air supply must be dry enough to
prevent ice formation at temperatures
below 2 C (35 F)
• Air Pressure:
Minimum 2.75 bars (40psi)
Maximum 8 bars (120psi)
Note: Recommended Air Pressure:
4-6 bars(60-80psi)
• Air Filtration:
40 Micron Filter
• Operating Temperature:
0° C (32° F) to 70° C (158° F)
• Actuation Time:
- Time to open: 0.6 seconds at 90°
pivot rotation angle*
- Time to close: 0.6 seconds at 90°
pivot rotation angle*
* Reference cycle time chart for other rotation
angles in the ECG Data Sheet (DS) manual.
Flow controls are optional. Clamps have fixed
orifices. Clamps do not require flow controls
unless slower actuation times are desired.
Caution: Operating the unit faster than the
recommended limits will cause premature
wear and may cause failure.

Installation
Installation/Set-Up Guidelines
1. Connect filter, valves, regulators, flow
controls, air hoses and fittings to cylinder
ports as shown. After connecting air hoses
and cord sets, verify that hoses and cords
do not interfere with the proper operation
of the Power Clamp. Secure cords if
necessary.
Note: Do not use under sized components
that supply air to the unit. Under sized
components will not provide adequate
air flow required to actuate the power
clamps within specified cycle times.
Installation Test Procedures
Norgren Power Clamps use a before center
toggle locking mechanism for constant high
output force and positional accuracy of the
clamp arm. Improperly installed, adjusted, or
maintained clamps can fail to open. Use the
following test procedure to verify that
application problems do not exist whenever
installing or adjusting clamps:
1. Adjust line pressure with regulator to
4-6 Bars (60-80 psi).
2. Cycle clamps open and close 3-5 times
and stop when arm is in the closed
locked position. (Reference drawing A)
3. Actuate air control valves to cycle clamps to
arm open position. (Reference drawing A)
4. Inspect all clamps in the cell to verify that all
arms have opened.
5. Remove and replace any clamps that fail
this test or investigate for other problems.
If the clamp hasn’t opened, then determine
if weld slag build-up or external interference
has caused clamps to fail test. (Reference
the Trouble Shooting Guide in this manual).
This test simulates conditions experienced
during operation and will highlight potential
problems long before they would happen.
The test can also be used as an aid for
determining suitability of marginal applications.
Norgren recommends that this simple test
be performed whenever changes or
adjustments are made.
Note: Consult Norgren’s Application Charts in
the ECG Data Sheet (DS)•Manual for
application parameters, or contact Norgren
Customer Service Department for additional
questions or in need of further assistance.

Lockout Precautions
The key to safely operating any automated
equipment is to use common sense and to
adhere to the safety procedures of your plant.
Before maintaining or repairing any
Norgren Automotive equipment, perform the
following lockout precautions.
WARNING!
The following procedures are intended to
supplement the safety rules of your plant,
NOT to replace them. Always follow the
safety rules of your plant when working
on Norgren equipment.
• Power down and lock out electrical
systems. Check voltage and current gauges
to ensure that all power is removed.
• De-pressurize pneumatic systems. Check
pressure gauges to ensure that all residual
pressure is removed.
• De-pressurize hydraulic systems
(if included). Check pressure gauges to
ensure that all residual pressure is removed.
• Follow your plant lockout procedures when
working on the automation and hang a
“Lock Out” tag on the control enclosures
main disconnect switch and pneumatic
lockout valve.
• Mechanically lock out the automated
equipment. Insert lock out pins or bars to
prevent lifts and shuttles from moving.
