Programming and Running a Sequence
3. Type SS2 and type the values below for example state 2, followed by .
: ss2
Active (Y)? (no change)
Ramp rate, degC/min (0):100
Setpoint (0):100
Hold time, seconds (0):10
3. Type SS3 and type the values below for example state 3, followed by .
: ss3
Active (N)? Y
Ramp rate, degC/min (0):200
Setpoint (0):200
Hold time, seconds (0):30
4. Type SS4 and type the values below for example state 4, followed by .
: ss4
Active (N)? Y
Ramp rate, degC/min (0):200
Setpoint (0):300
Hold time, seconds (0):25
Always verify that changes were made by repeating the command
to view the current state, or SS to show all states.
5. Type SS. If the data were entered correctly, the screen will reflect the following
information (except for the italicized explanatory text).
State Active Rate Temp Time
1 Yes 0 25 5 Start at 25°C, hold for 5 seconds (no ramp in state 1)
2 Yes 100 100 10 Ramp @ 100°C/min to 100°C, hold 10 seconds
3 Yes 200 200 30 Ramp @ 200°C/min to 200°C, hold 30 seconds
4 Yes 200 300 25 Ramp @ 200°C/min to 300°C, hold 25 seconds
5 No 0 0 0 If no other state is active, the fan will automati-
cally come on to cool the column down to the
State 1 temperature. The FTC will hold “Ready”
for the next run. (Refer to the section entitled “Fan
Modes” on page 9.)
6 No 0 0 0
7 No 0 0 0
8 No 0 0 0
NOTE: State parameters are saved when the FTC is powered down. Pushing the RESET
button on the front of the FTC may erase the state parameters.
Setting Equilibration Time
Equilibration Time delays the “Ready” flag for state 1, allowing time for the column
temperature to equalize once the temperature has been reached. A “Go” command will
not execute until this time has elapsed. The equilibration time is preset to 5 seconds. To
change it:
1. Type ET=n, where n is the desired equilibration time, in seconds.
2. Type ET to verify that the change has been executed.
