Clamps, Coupling outputs
, and
Fixturing Timers
are all similar terms used to describe pneumatic
outputs that can be used for various functions. These outputs can be used to actuate tooling, manipulate
a part, or activate a pneumatic seal around a part.
All outputs are supplied as four-way valves
with one normally open and one normally closed port. The outputs can be used as a three-
way valve by plugging the normally open port. The normally open port will be plugged from
the factory.
The valve timers work in an On-delay, Off-delay manner. The output is set at the beginning of the timer.
At the end of the cycle the outputs will deenergize in the opposite order.
Pre-Test Op1 is
output 1
. To enable the output, a minimum of 0.1 sec. must be entered. This timer is
the amount of time the output will be set prior to the test start.
Pre-Test Op2 is
output 2
. To enable the output, a minimum of 0.1 sec. must be entered. This timer is
the amount of time the output will be set prior to the test start. If op1 is set, op2 will follow and run its
timer before the start of the test.
Leaving the post-test timers at zero will de-energize all valves at the end of the test. Placing time in the
‘
post test
’
will de-energize the valve in the opposite of the order they were initiated.
