1.1: Safetimeter Switches and Connectors
ON/OFF
This is the unit’s power button. The button can be depressed to turn it ON or OFF.
There is a timer sequence built into the controller that will time out after a fixed
duration of time if the meter is not being used. The power cord may be plugged into
120 VAC outlets for recharging the battery, in the ON or OFF position. The controller is
designed to operate from its internal battery.
TIME UP/TIME DOWN
This switch determines the direction of the test. In the TIME DOWN position, the
controller will send a signal to the Auto-Hand to release the plunger in the down
direction. In the TIME DOWN position, you are performing a standard test according
to OSHA requirements. The switch should be in the TIME UP position when checking
press top stop.
STOP TIME
(mSEC)/ SAFETY
DISTANCE (IN)
This switch is used to select the display mode, either time or distance. Time is
measured in milliseconds and distance is measured in inches. The switch can be
thrown before or after the reading to convert form STOP TIME to SAFETY DISTANCE
or SAFETY DISTANCE to STOP TIME.
FULL REV/PART REV This switch is used to determine the press clutch operation mode, either full or part
revolution. The majority of tests are run in the part revolution mode.
CONTROL START
POINT (IN)
Known as CSP, this dial is used to set the point in the stroke at which the command to
start timing and fires the Auto-Hand is given. When the CSP dial is turned clockwise,
the dial will increment and decrement when turned counterclockwise. The CSP dial
reads in tenths of an inch. Example: 123 equals 12.3”.
MANUAL START
This jack is used with the optional manual start switch.
AUTO-HAND
This connector is used to connect the Auto-Hand to the Safetimeter.
