P2 SAFETY DEVICE METHOD
: This function determines
how the stop-time measuring actuator will stop the
machine.
TWO-HAND, OTHERS
is used when the
STM test is performed with the actuator depressing the
initiating means. The
LIGHT CURTAIN
setting is used
when the STM test is performed with the flag attached to
the actuator. The flag is used to interrupt the sensing field
of the light curtain. If a
LIGHT CURTAIN
is used, the light
curtain
RESPONSE TIME
and
RESOLUTION
(Minimum
Object Sensitivity) should be entered as described below.
P2 APPROACH SPEED
: This function determines the hand
speed constant value used in the stop-time measuring
calculation. The factory setting is 63 IN/S (inches/second),
using the OSHA formula as shown on page 7.
P2 RESPONSE TIME
: When the
P2 SAFETY DEVICE
METHOD
is set to
LIGHT CURTAIN
, the light curtain
response time is programmed in this setting for use in the
stop-time measuring calculation. If the flag on the actuator
is used to interrupt the light curtain and stop the machine,
enter 00.0 because the response time of the light curtain
will automatically be measured.
P2 RESOLUTION
: When the
P2
SAFETY
DEVICE
METHOD
is set to
LIGHT
CURTAIN
, the depth penetration
factor (based on the minimum object sensitivity) is required
when using the ANSI safety distance formula as shown on
page 8. If using the OSHA formula, do the same as ANSI,
even though this added distance is not part of the formula.
(See page 26 for step-by-step
instructions.)
P3
MEASURING
DIRECTION
: This function determines
if the stop-time measuring actuator stops the machine
on the downstroke or on the upstroke. The downstroke
is usually used to determine the safety distance. The
upstroke stopping time may be useful when adjusting the
counterbalance.
MM PARAMETER 2
SAFETY DISTANCE
When in the
P3 SPM
METHOD
(described below)and
using either the
MANUAL
or
TEACH IN
mode,the actuator
can be released either the first or the second time the
cable sensor reaches the start point of the measurement,
stopping the slide motion at approximately 90°or 270°.
P3 MEASUREMENTS MACHINE
000:
This function
determines the number of measurements that will be taken
per machine. The factory setting of 000 allows unlimited
measurements but does not store any data. To set the
number of tests per machine, select a number between
001-010
. A maximum of 10 tests per machine (maximum
of 30 machines) may be taken. Data will only be stored
when a number between
001-010
is selected. After the
selected number of tests are completed, the device starts
measurements for the next machine.
P3 MEAS. MODE
: This function determines the method
used to advance to the next measurement within the
MM
STOP-TIME
MEASURING
menu. In the manual mode, the
user must press
ENTER
to advance to the next step in the
measuring process. In the automatic mode, after taking
an STM reading, the unit will automatically advance to the
next measurement after counting down through the preset
time (see page 26 to adjust time).
P3 SPM METHOD
: This function determines at what point
in the stroke the test will be performed. This is referred to
as the start point of measurement.
In the
TEACH-IN
mode, the start point of measurement is
entered into the STM unit at a specific point in the
MM STOP-
TIME MEASURING
menu. The cable sensor must be at the
desired start point of measurement when
ENTER
is pressed.
In the
MANUAL
mode, the operator enters the stroke length
when prompted in the
MM STOP-TIME MEASURING
menu.
In the
TEST STROKE
mode, the highest SPM (Strokes Per
Minute) of the crankshaft on the down-stroke is measured.
P3 MACHINE NO/MACHINE ID:
This function determines
if a machine ID No. will be required. If this is set to
YES
,
a prompt for the machine ID No. appears on the screen in
the
MM STOP-TIME MEASURING
menu. If this variable
is set to NO(factory setting), each machine is referred to
by a sequential No. and a machine ID No. is not required.
