Important: When mounting RUN and INCH buttons, ensure that:
all RUN buttons and both INCH buttons are either guarded or
flush-head pushbutton switches, such as Allen-Bradley Bulletin 800P
Palm Operated Pushbuttons. You can operate guarded buttons only by
reaching through their guard rings.
the distance between each left RUN or INCH button and its
corresponding right RUN or INCH button is great enough to allow
operation of both buttons only by both hands.
all RUN and INCH buttons are located at greater than minimum safe
distance from the point of operation of your press as specified in OSHA
Regulations, Title 29-Labor, Chapter XVII, Section 1910.217, and
ANSIB11.1, section 5.3 Formulas for calculating the minimum safe
distance are included.
Use the optional diagnostic binary display shown in Figure 6.13 to
troubleshoot your press. Chapter 7 lists the diagnostic messages.
We recommend Allen-Bradley Small Pilot Lights, Transformer Type (cat.
no. 800T-PS16R) with 1771-OA Output Modules. You may order color
caps separately (red is standard):
Red = cat. no. 800TĆN122R
Green = Cat. no. 800TĆN122G
Amber = cat. no. 800TĆN122A
Blue = cat. no. 800TĆN122B
White = cat. no. 800TĆN122W
Clear = cat. no. 800TĆN122C
You may also want to order Small Pilot Light Guards (cat. no.
800T-N226), to protect the caps against accidental breakage.
STOP-ON-TOP FAULT - tells an operator that the brake is faulty. If the
shaft overshoots the near top position in inch, single, or continuous mode,
both voting processors prohibit clutch actuation, and turn on this indicator.
(See Table 5.a and Figure 6.14)
RUN WINDOW - turns on when starting the press in these modes:
single-stroke: When both RUN buttons have been pressed at one
station, other active stations have 5 seconds to press their RUN buttons
as shown by this indicator.
