alters the function of the valve monitor inputs in the following manner:
Valve Monitor type 000: Air Valve With Internal Monitor
Input #44 Input from valve monitor 1 (0 volts = valve fault)
Input #45 Input from valve monitor 2 (0 volts = valve fault)
This is a "static" valve monitor. If either valve monitor input goes low the press control will immediately
stop and further stroke initiation is prevented until the inputs are in the RUN condition (+24 volts). This
is intended to be used with a clutch/brake valve that internally monitors for a fault condition, provides an
output that indicates a malfunction, and remains locked out until an external reset solenoid is energized
by an operator pressing a valve reset button. None of the factory programmed timers are used with this
monitor.
Valve Monitor type 001: Air Valve with Proximity Sensors Only
Input #44 Input from proximity sensor 1
Input #45 Input from proximity sensor 2
This is a "timed" valve monitor. When the press control's clutch/brake output is de-energized, both
proximity sensors must report that the valve is in the Off position (inputs at 0 volts). When the press
control's output is energized, both proximity sensors must report that the valve is in the On position (both
inputs at +24 volts). Since the valve has some physical reaction time, two factory programmed parameters
are provided. The parameter ‘V/M Turn On Time” sets the maximum amount of time (in mSec) that both
inputs #44 and #45 must switch high when the clutch is engaged. If both inputs do not switch high within
this amount of time the clutch/brake valve is turned Off and “V/M Pull In Fault” is reported as the reason
for the stop. The parameter “V/M Turn Off Time” sets the maximum amount of time (in mSec) that both
inputs #44 and #45 must switch low when the clutch is dis-engaged. If both inputs do not switch low
within this amount of time the present running status will indicate a “V/M Drop Out Fault”. A fault from
this type valve monitor generates an immediate stop and requires that the operator press the RESET
ERROR softkey in the press control menu before any further strokes can be initiated. The parameter
“V/M Track Time” is not used and should be set to 100.
Valve Monitor type 002: Valve with Internal Monitor and
Clutch Line Pressure Switch
Input #44 Input from valve monitor (0 volts = valve fault)
Input #45 Input from Clutch Line Pressure Switch
This is a "static and timed" valve monitor. If the static input #44 goes low the press control will
immediately stop and further stroke initiation is prevented until the valve monitor input is in the RUN
condition (+24 volts). This static input is intended to be used in conjunction with a clutch/brake valve that
internally latches the fault condition until a valve reset solenoid is energized. In addition, when the press
control's clutch/brake output is de-energized, the clutch line pressure switch must report that there is no
pressure on the output of the clutch valve (input at 0 volts). When the press control's output is energized,
the clutch line pressure switch must turn On (input at +24 volts) within a programmed time to indicate that
