Check Operation of Safety Interlock System
CAUTION
Do not disconnect interlock switches. They are
for the operator's protection. Check operation
of the switches daily to make sure the interlock
system is operating correctly. If a switch is not
operating properly, adjust or replace it before
operating the machine.
Interlock switch operation is described in the ProCore
648 Operator's Manual. The ProCore is equipped with
an Aerator Control Module which monitors interlock
switch operation. Information on this Control Module is
described in the Operator's Manual and in the Compo-
nent Testing section of this Chapter. Testing of individual
interlock switches is included in the Component Testing
section of this Chapter.
Electrical System
The Safety Interlock System of the ProCore 648 ensur -
es the following operations:
1. The engine should crank only when the traction lever
is in the neutral position.
2. When aerating, if the traction lever is released from
the forward position (moved to the neutral or reverse
position), the coring head should automatically raise
and the coring crankshaft should stop rotating.
3. If the coring head is stranded in the lowered position,
the coring head will not raise unless the lift reset switch
is depressed.
