Light Lamp Timer and Blower Timer
Both timers allow you to decide whether the fluorescent lamp or blower will
operate continuously or for a limited time period that you select. This may be
desired for energy-savings as well as a safeguard for light-sensitive materials.
Interval
When the “interval” option is selected, the Light Lamp Timer or Blower
Timer menu is displayed.
Interval Timer
This window lets you set the amount of time for the fluorescent
lamp to stay lit once activated or the blower to stay running. Use the
“
▲” and “▼” buttons to select the amount of time, then press the
“ENTER” button to set the interval.
Continuous
In the continuous mode, the fluorescent lights or blower will remain
on until the “LIGHT” button is pressed, or the “BLOWER” button is
pressed.
Blower Operation
This blower switch allows you to run the ductless enclosure and the face
velocity will be displayed. Note: Always work in the ductless enclosure with
the blower running.
Enclosure Set Up
These selections allow for the customization of the display and the ductless
enclosure operation.
Units of Measure
This option allows you to select the air velocity units of measure. When
“Metric” is selected, the air velocities are displayed in meters-per-
second. When “US” is selected, the velocities are displayed in feet-per-
minute.
Security Lock
NOTE: The security lock automatically reactivates and locks out
the keypad.
The security lock feature prevents parameters of the Paramount from
being changed by unauthorized users. To engage the security lock,
access the Security Lock submenu. Select the “ON” option, and press
the “ENTER” button. Once engaged, the operator must enter the proper
password to lock or unlock the enclosure.
