SECTION 3—INSTALLATION OF COMPONENTS
Function Tests of Two-Hand Control
(continued)
2.
With the main motor drive on, the flywheel rotating, the actuating means selector switch set to
HAND
, and the mode selector switch set
to
SINGLE
, perform the following tests.
a. Depress both palm buttons concurrently within the programmed anti-tie-down setting (100 - 7000 ms) and the press will begin a
stroke.
b. Hold the palm buttons down for the entire stroke. Release one palm button and try to start another stroke by reactuating the palm
button that was just released. The press should not begin another stroke. Repeat this step with the other palm button. The press should
not begin another stroke. This verifies the control has antirepeat.
c. Depress both palm buttons and release only one palm button on the downstroke. The press ram should stop. Reactuate the palm button
that was released. The press should not finish the stroke. Both palm buttons must be released and reactuated in order for the press to
finish the stroke. Repeat this test while releasing the other palm button. The press should not finish the stroke. Both palm buttons must
be released and reactuated in order for the press to finish the stroke. This verifies the control has nonresumption of interrupted stroke.
If any of these function tests fail, corrective action must be taken before running production.
Foot Switch

If you elect to use a foot switch, all personnel must be warned that it is
impossible for a foot switch to provide any form of point-of-operation
safeguarding. It is the responsibility of the employer (user) to always
provide an appropriate guard and/or device to prevent bodily injury
whenever a foot switch is used to initiate a machine cycle. (See OSHA 29
CFR 1910.217 (c) for safeguarding.)
The following steps should be taken when using a foot switch:
A method of safeguarding (light curtain, guard, gate, pullback, or restraint) the
point of operation must be provided before installing or using a foot switch.
The machine will not operate or must not be operated until you either:
1.
Electrically interlock or
2.
Mechanically safeguard the machine’s point of operation with a guard or device.
