Stop” terminal block in order for the device to properly
top stop the press.
VII. Clutch Air Pressure Switch/Counter Balance Pressure
Switch
The system requires a separate N.O. switch on both the
Clutch Air Pressure supply “Clut AIR” and the Counter
Balance Air Pressure “CBAL AIR” supply. Without these
inputs the system will stay faulted.
VIII. Main Motor Forward Contact
The system requires a contact from the Main Motor
Forward Starter to be wired into the “MTR FWD” input. This
is needed in order to move the ram in single and continuous
modes. It is not needed in Inch mode, and allows the press
to inch with the main motor off, also known as “dead motor
inch”.
IX. Immediate Stop Input
The “Immed Stop” input must remain high for sourcing
inputs, and low for sinking inputs in order for the press to
run in any mode. Losing the “Immed Stop” input will
immediately stop the press. This input can be used to stop
the press for auxiliary equipment such as die protection. An
auxiliary terminal block labeled “Immed Stopj” is available
for use if more than one immediate stop device is needed.
“Immed Stopj” is not an immediate stop device input. If the
auxiliary immediate stop terminal block
“Immed Stopj” is used, it must be wired in series with the
“Immed Stop” terminal block in order for the device to
properly immediately stop the press.
X. ESR-1 and ESR-2
These inputs should be wired so that two identical
(redundant) circuits are used to stop the clutch. Each
contact in the series should have two sets of contacts.
This is your emergency stop for the press. Auxiliary
equipment that is not safety related should be wired to the
immediate stop input. These circuits are wired to directly
shut off power to the clutch valves when the string is
broken. If the circuits are not identical, PP150 faults will
occur because of power being removed from one of the
solenoids and not the other. If this does occur the valve
will have to be reset. These circuits are also monitored by
the controller and will cause a mismatch fault during a
mismatch condition. In order to reset the fault, both
circuits must be turned off, the PP150 reset button must
be pushed, and then both circuits must be turned back on.
Press the clutch reset button again to make sure no faults
exist.
