INSTALLATION
SECTION 3-6
IF NECESSARY, REVERSE THE MOTOR ROTATION
WARNING!
With all power to the electrical control panel disconnected and locked out, reverse any two of the three
power line conductors to the machine. If there is more than one motor on the machine, and one is turning
in the wrong direction, and one isn't: reverse any two of the three line conductors at the overload relay of
the motor that you wish to reverse.
Unlock the power and switch it on at the electrical disconnect (if necessary, replace the fuses).
Re-check the rotation direction of the motor(s).
INTERLOCK SWITCH TEST PROCEDURE
With the machine stopped, perform the following steps:
TURN OFF and LOCK OUT THE POWER per OSHA 1910.147 OR ANSI Z244.1-1982
(Lock-out/ Tag-out of Energy Sources).
Use the wiring diagram appended to this manual to locate the interlock switch terminal strip in the
junction box control panel.
The wires for the upper chamber interlock switch are numbers 1 and 16.
The wires for the screen cradle interlock switch are numbers 16 and 5.
Connect an ohmmeter across each interlock switch terminal or across all interlock switch terminals
(wire numbers 1 and 5).
Switch the ohmmeter resistance to the lowest scale. When the interlock actuator screws are in place
and properly activating their switches, the ohmmeter should read zero resistance.
When either or both actuator bolts are withdrawn, the ohmmeter should read infinite resistance.
Loosen ONE actuator screw 3 to 4 turns. If, the meter reads INFINITY, before the screw can be
completely removed, the INTERLOCK IS WORKING. If the meter reads ZERO RESISTANCE, when
the actuator screw is completely REMOVED, the INTERLOCK IS NOT WORKING.
REPLACE THE FIRST ACTUATOR SCREW TESTED BEFORE TESTING THE SECOND
ONE.
If an interlock does not work, the complete mechanism, including the switch, must be removed and
disassembled to determine the cause of the malfunction.
