Applications
The setpoints selected (included) for a program cycle are identified by the ADD symbol: a plus
"+"
sign
inside a diamond frame. Each cycle starts by first going to the top (first) setpoint. Afier the soak time
expires at that setpoint, the system continues "At Temperature" for the set test time, then the cycle
continues to the next (second) setpoint. After the soak time and test time expires at that setpoint, the cycle
continues to the next setpoint, and so on until all set test temperatures have been performed. Afier the
soak time and test time expires at that last setpoint, provided more than one cycle has been programmed,
the TP04100A will then go to the top (first) setpoint to begin the next cycle until the set number of cycles
have been completed or the STOP button is pressed (see Figure 3-8, below).
Note:
If
system
appears to "hang"
and
not advance to next cycle step
when "At Temperature" (during
"test time"), from Program Operation Screen, then "Stop" cycling, enter "Setup," select "Define" to
display Define Parameters Screen, and check the "Maximum test time (sec)" setting. This sets how long,
in seconds, the system will remain "At Temperature" after the soak time has elapsed, before advancing to
the next cycle step. Use "Select" to select ccMaximum test time (sec)," and use the Rotary Encoder to
adjust the setting. To proceed to next temperature during cycling without delay, set to 0 (zero) seconds.
Press "Done" to save the entire test setup, then select "Program" and press "Cycle" to resume cycling.
During cycling, a "Cycle" counter field displays the number of cycles completed, labeled "Transition"
then "Soak" (seconds), then "At Temperature" (seconds) to indicate time elapsed per cycle sequence
status (see Figure 3-8, below).
While the system is temperature cycling, the "Cycle" label changes from "Cycle" to "Stop" (see Figure 3-
8,
below). By selecting "Stop" the operator can stop both air flow and temperature cycling.
SETUP:
This selection accesses the Program Test Setup Screen (see Figure 3-12, on page 3-33) where the
operator can change setpoint values and changelselect Test Setup programs.
