Mount the Guardian II in a location that provides access by the operator
and facilitates wiring by the electrician to the bodymaker control.
From Bodymaker
Control PLC
From Sensor on Domer
(Via Junction Box)
Sensor Junction Box
The safety of any system incorporating the Guardian II
product is the responsibility of the assembler of the system.
Make sure bodymaker is stopped before installing sensor on the bottom former.
Mount the sensor junction box
to allow the sensor to be routed
between the domer and the
Guardian II.

Install the sensor bracket, with Sensor and wire attached, to the bottom
former with two ¼ --28 screws, 0.250” long. Do not torque them yet
because they must be loose to set the sensor gap in the next step below.
Set the distance between the sensor and the Outer Housing flange. Use a 0.025” (0.635
mm) thick feeler gauge to set the gap as accurately as possible. The size of the gap is very
important because the gap directly effects the strength of the signal from the sensor.
The Guardian interprets the strength of the signal to determine value of the over travel.
Once the gap is set, torque both screws to 20 lb.-ft or 27 N·m. Re-check the gap to be
certain that the sensor did not move while the screws were being tightened. The 0.025”
(0.635 mm) gap should be maintained.

Set the upper limit of the speed zone. The low limit for the next zone will
automatically fill in based on the high limit of the previous zone.
UPPER LIMIT: Most can makers set the upper limit parameter so that a double
can will trigger the Guardian II to issue an upper limit error alarm.
LOWER LIMIT: This should be set so as to detect a diminishing over travel.
DELAY: This is used to set a delay before the low limit error signal is issued to
allow time for the bodymaker to get to operating speed.
Add these parameters for each of the speed ranges you specify. You can have as few
as 1 zone and up to 10 zones.
HOW THE GUARDIAN II WORKS
The Guardian II senses each over travel cycle and compares the reading to the
upper and lower limits. If the individual reading falls outside of one of the limits,
it will display an ‘Upper Limit’ or ‘Lower Limit’ error and send a signal to shut down
the bodymaker (if configured to do so). The display shows an average of the last
16 individual over-travel readings.
The Guardian II will automatically use the settings appropriate for the current
operations speed.
Press on screen to select
the parameter you want
to set.

4. Maintenance
5. Part Identification
No periodic maintenance of the equipment is required. Investigation of any issues with
the performance of the equipment needs to be performed in a safe manner. Only trained
maintenance personnel should gain access to the inside of the case.
The circuit breaker is rated for 2 amps.
The equipment is safe to use if the circuit breaker will close. If the circuit breaker will not
close, check the wiring to ensure it matches the wiring diagram.
Sensor and Bracket Assembly: P/N 200-77-32
Make sure bodymaker is stopped before installing sensor on the bottom former.

It is important to ensure the screws holding the sensor bracket to the Cylinder Housing
are able to hold the sensor bracket in place for proper functioning and to avoid potential
damage to the sensor or bracket. Specialized washers have been implemented
beginning in 2021 and can be used retroactively to reduce the potential for the screws to
loosen.
Cylinder Housing Sensor Mounting Hole Maintenance
Check mounting hole helicoil [P/N PP-3591-4-250] condition and replace if necessary.
Verify that the thread inserts are in good condition and there is nothing in the hole that
will keep the screw from fully seating on the mount. REPLACE BROKEN THREAD
INSERTS.
Maintenance Supplement –Sensor Bracket Retention

Lockwasher Installation –P/N HDW-WSH-01015
Check mounting hole helicoil condition and replace if necessary.
When installing the Guardian sensor mount, use these included washers, installed as shown
above to reduce the chances of the mount loosening during operation. Washers can be reused
until there is visual deterioration of the serrations or wedges.
Adjust, install and torque mounting screws to 20 lb.-ft or 27 N·m.
