CLEAN ROOM DEVICES CRD216SS Operation Manual page 12

 The CRD216SS expansion operation is designed to let the operator expand each piece of
tubing twice. After the first expansion, the jaws will close and the operator rotates the
tube 90 degrees and the jaws will automatically expand again using the sensor. This
ensures that the tubing is expanded in a uniform fashion, and not deformed in only one
direction. To assist with this 2-step expansion operation, there are 2 time delay relays on
the unit.
o Expansion Time – This setting adjusts the rate (0.5-5.0 seconds) at which the
tube expansion occurs. The rate at which the tube is expanded is critical to
prevent tearing. Some stiffer tubing might need a longer expansion time, while
softer tubing can be expanded rapidly.
o Interval Time – This setting adjusts the time delay rate (0.5-5.0 seconds) at
which the jaws will cycle. It is adjusted to allow the operator to rotate the tubing
90 degrees at a comfortable pace between expanding.
 Remove the hole plugs with a screwdriver on the rear cover to gain access to the Time
Delay adjustment pots. Figure 3.3.1
 Using a small Phillips drive screwdriver adjust the Time Delay relays. Figure 3.3.2
