Require Password –
Normally it is not required to use a password (i.e. 3 key press sequence of the blower
and hidden key). If the option is turned on, it would be required to use the correct
password to turn on the blower. The default password once turned on is blower-
hidden-blower keys in sequence. The password can be changed in the blower
password option menu.
Allow UV light anytime –
Normally the UV light is interlocked with the window being in the closed position.
For service purposes only, if the function is active, the UV light may be turned on at
any window height.
Note: In addition to the Allow UV light anytime system function, there is a double redundant UV light
window interlock relay. To override the UV light window interlock relay, the relay itself must
also be shorted. (See electrical schematic for reference).
Manual Blower Restart –
Normally when the blower is actively running and a power interruption occurs.
The blower will automatically come back on when power is restored. If this function
is turned off, the blower will not automatically come back after a power interruption,
but would require the user to press the blower key to restart the blower.
Nite Care –
Normally the Nite Care function is turned off. If selected and turned on, once the
blower is actively running. Upon closure, the blower will continue to run at a
calibrated lower speed level to keep the workzone interior sterile.
The PresurFlow™
will indicate(s) blinking green LEDs along with green LED above blower key. The
fluorescent light will turn off (blue LED above light key will blink if window closure
turned it off) and become inoperable; however the UV light can be used.
Disable PresurFlow™ -
If this function is active, the digital pressure sensor and alarm function are turned off.
Temporary Nite Care -
When this option parameter is turned on and the other requirements below are met,
the blower key (when held for 5 seconds) will toggle blower between normal and Nite
Care blower speed. The Nite Care blower will time out, based on the Auto Timer
duration for Nite Care without a blower key press and the blower speed will revert
back to normal. Closing the window will automatically terminate.
In addition to turning this option on the following requirements must also be met
•
The Nite Care must be selected
•
Password must be selected
•
Window is at normal height and blower is running
•
Nite Care blower auto timer must be set for a minimum of 15 minutes.
Disable audible alarms / audible key feedback Normally audible alarms from the
PresurFlow
™ monitor and audible key feedback are present to provide an audible
sound to the user. If this function is active, all audible sound will be silenced when the
control system is in normal run mode. Audible sound will still occur in any
service/calibration menu function.
