♦ Use Drier
The User Drier feature is used to change the method of dehumidification. The Chamber defaults to
Dehumidify Coil. Select the Use Drier method when to achieve very low humidity.
The Use Drier state controlling the dehumidification method is controlled by the profile while the
chamber is running a program. To monitor the On/Off state of the Drier, go to the Events\Event Output
folder and observe the LED indicator next to the Use Drier label. The light is red when the drier is
active, gray when it is inactive. To change the default dehumidification method for steady state
operation go to the LEV1 folder under Setup\L-Values\LEV1 and select the desired default method:
Drier or Dehumidify Coil.
♦ LEV 2
LEV2 (Logic Event 2) controls the vacuum device. When enabled it activates the vacuum device even
if OT17 is set to Purge.
You may select the LEV 2 method while the chamber is running in manual mode or programmatically
from within the Add Step Wizard using the Setpoint step. To monitor the On/Off state of LEV 2, go to
the Events\Event Output folder and observe the LED light next to the LEV 2 label. The light is red
when the LEV 2 is activate, gray when inactivate. Note that the default LEV 2 setting is always off.
♦ OT11 TPM
The OT11 TPM feature is used to change the output 11 control mode. The chamber defaults to On/Off
control mode. When you select OT11 TPM, the controller temporarily switches to the time
proportioning mode.
Output OT11 TPM (Time Proportioning Mode) can be monitored from within the Events screen. You
may change the setting programmatically from within the Setpoint step. To monitor the state of the
OT11 TPM setting, go to the Events\Event Output folder and observe the LED indicator next to the
OT11 TPM label. The light is red when the time proportioning mode is active, gray when it is inactive.
To globally change the default OT11 TPM setting for Steady Stat mode, go to the OT11 folder under
Setup\Special Functions\OT11 and select the desired default method: On/Off Control Mode or Time
Proportioning Control Mode.
