SECTION 3—INSTALLATION OF COMPONENTS
Foot Switch
(
continued)
Install either the electrically interlocked method of safeguarding or the mechanical guard or device.
1.
When an electrically interlocked method of safeguarding the point of operation is chosen, connect the interlock to the safeguard interlock
terminals (P8-17 and P8-18) in the control box and as shown on the control wiring schematic (wire numbers 86 and 87). If a light curtain is
used as the point-of-operation safeguard, it does not need to be interlocked in to P8-17 and P8-18. Refer to the control wiring schematic
for proper terminal connection.
2.
When a mechanical guard or device (nonelectrically interlocked) is chosen, the safeguard interlock terminals (P8-17 and P8-18) are not
used. In order for the machine to operate with the use of a mechanical guard or device, the
safeguard interlock
terminals must be
connected.
Note: When the mechanical guard or device is removed for other modes of operation, the safeguard interlock terminals must be disconnected.
Never use a foot switch to operate this machine unless a point-of-operation guard or device is provided and
properly maintained.
The mechanical guard or device must be properly installed, used and maintained. It must always prevent all
personnel from bodily injury.
If the mechanical guard or device is not used, is removed or is defeated, an electrically interlocked method of
safeguarding must be used and connected to the safeguard interlock terminals P8-17 and P8-18.
When installing the optional foot switch, be sure the wiring schematics are referenced for proper connections. Be sure to maintain the foot switch in
first-class condition. It must always be wired properly and the protection on the top, sides, and front must always remain in place.
Supervisory Control Station
(If furnished)
When two or more palm button or foot switch operating stations are required on one machine, one supervisory control station
is required at each operator station. This remote control station consists of one STATION ON indicator light and an OFF/ON
keyed selector switch in an enclosure. The ON position allows the operator to use that station and the OFF position deactivates
only that station. If all the supervisory control stations are in the ON position, the palm buttons or foot switches must be
depressed within the timing period set in the anti-tie-down program (pages 56 - 57) in order to initiate a machine stroke.
Multiple Operator Junction Box
(If furnished)
When multiple operator stations are required, this junction box is furnished separately for wiring up to four (4) operator stations. This junction box
interfaces palm button assemblies/control bars and foot switches, and will not allow the press to run if palm buttons or a foot switch is actuated
without its supervisory control station on. LED indicator lights on the cover of the enclosure show the status of each operating station—green for
ON, red for FAULT, and amber for OFF. Refer to the electrical schematic furnished with your order for proper wiring of each station.
Bar/Run Station
(If furnished)
This remote bar/run station can be used in conjunction with manual turnover bar operation when setting dies in the
press. The flywheel must have holes in the periphery for insertion of the spring-loaded turnover bar (or the flywheel can
be manually turned when the flywheel cover is removed). The remote station includes a three-position selector switch for
BAR, OFF, RUN, and one push button used for energizing the dual solenoid air valve to engage the clutch and release the
brake. The flywheel must be at rest (static) when engaging the clutch. After the clutch is engaged, the die set-up person
can manually turn the flywheel with the spring-loaded turnover bar. This then causes the ram to move.
