out slowly and do not let it go. If the cable snaps back into
the sensor, it could cause damage. Make sure the cable is
free of any obstructions. See photo below.
When checking the stopping time of a machine which has
two-hand controls, the actuator is used. This actuator is
designed to release or actuate the run button. Make sure
the support foot and pushbutton plate are installed properly
(see Figure 3.1 below).
The actuator must be
cocked before using it (see
Figure 3.1) for the test.
Place the cocked actuator
over one of the two-hand
controls, while putting the
other hand over the second
two-hand control.
Operate both controls simultaneously. When testing the
machine, the actuator releases at 90°(OSHA) causing the
machine to stop.
Note: This actuator can also be used to push the emergency-
stop button.
SECTION 3—OPERATING INSTRUCTIONS
Stop-Time Measurement Device
BENCH TEST
Before using this STM device on a reciprocating
machine, it can be bench tested. Your hand and arm
can simulate the action of the ram or platen. Follow the
step-by-step procedures in the next section for this test.
Stopping times and safety distance will vary due to the
inaccuracies in your arm movement.
USING THE STOP-TIME DEVICE
Before using this device, be sure that the battery is fully
charged. The green indicator light will flash when it is
fully charged.
An option is to use the STM device while it is plugged into
a 120V duplex outlet. Plug the wall transformer into the
outlet and the other end into the power port on the meter.
Plug the actuator and sensor into the appropriate
receptacles.
The meter can be removed or it can remain in the
carrying case. For convenience, when testing several
machines, you may want to leave the device in the case.
Using the shoulder strap, you can test the machines
without setting the device down. This may be very helpful
in the industrial environment.
Remove the sensor from the carrying case and place it on
the bed or bolster of the machine. Never place the sensor
where the dies can close on it. See photo below.
With the machine at top dead center of crankshaft
rotation or at top of stroke, place the magnet, which is on
the end of the cable, on the ram or platen. Pull the cable
