CP600 Pivot Operators Manual
OPERATION, SAFETY & MAINTENANCE
Section 1-20
© Pierce Corporation
July 2010
Your Pierce pivot requires 480 volt 60
cycle, 3-phase electric power to operate
suffi cient charge. There is also 110-volt
control power throughout the system. Oth-
er potential hazards include any injected
fertilizers and pesticides, and water under
pressure.
Note: Voltage is dependant upon location.
Voltage should not be more than +/- 5%
than the recommended voltage in your
area.
Sequence of Lockout or Tagout Procedure
1. Notify all affected persons that you are about to lockout the pivot, and tell them
why the pivot is being placed “out of service”. Before locking out the pivot, you
must familiarize yourself with the type and magnitude of the pivot’s energy source
and determine any related hazards.
2. If the machine or system is operating shut it down by rotating the forward /
reverse selector switch to the off position.
3. On the main control panel, turn the main disconnect lever to the off position so
the pivot cannot be energized while it is being serviced. Drain all water from the
system and disengage any automatic valves. If your pivot is rigged with an auto
matic valve, it must be locked out so that the pivot does not unexpectedly fi ll with
water while you are servicing.
4. Lockout the main disconnect (energy-isolating device) on the main control panel.
If working down line on the pivot, the tower disconnect switches on the individual
tower boxes must also be shut off.
5. After ensuring that no personnel are exposed, and as a check on having
disconnected the energy source, operate the start button to make certain the
pivot will not operate.
Lockout/Tagout Procedures
CAUTION: Return operating controls to “neutral” or “off” position after
maintenance is completed.
