The backgage is designed for sheets up to 1/4”
(6.4mm) thickness that weigh less than 150 lbs.
(68kg).
MANUAL FRONT GAGES
Fixed front gaging and material supports are avail-
able for the FM. Gage brackets and gage stops are
manually set to position material for forming. Front
gage brackets without gage stops can also be used
to support material. See Figure 8-3.

OIL HEATERS
Oil heaters are recommended for cold start ups and
cold running conditions. They are immersion-type
and are thermostatically controlled. They will only
maintain the oil temperature in the tank to permit
machine start-up, they are not
for heating up the
oil. The thermostat is set to start the heater if the
temperature falls below approximately 60°F.
PRESENCE SENSING SAFE-
GUARDING INTERFACE
This is a hardware/software package to interface
the FM controls with a customer supplied pres-
ence sensing device. When installed, this safety
device will prevent ram operation when a person
or an object is detected in the protected area. The
Guard On/Off Light is shown in Figure 8-4. It will
indicate that the Presence Sensing Device is
muted by switching from the ON light to the OFF
light. Contact CINCINNATI INCORPORATED if
totally disabling the Interface is required.

AUTO CROWN
The Auto Crown
option is a special bed with a
variable proportional crown which automatically
compensates for both bed and ram deflection for an
applied centered load of any magnitude and length
up to the nominal machine length. It causes the
bed and ram to remain parallel in the loaded con-
dition. With this device, the bend angle remains
constant along the length of the bend.
A machine equipped with Auto Crown does not
have a microcrowned bed. The bed top and ram
nose are machined straight.
The bed is sandwiched between two auxiliary cross
members. All three are pinned together at two
places near the end of the bed as shown in Figure
8-5. One or two hydraulic cylinders are mounted in
