2.2.4.10 Set Sash Cycle (Only for Motorized BSC)
To reset the sash cycles count to zero or to input the sash cycle count manually. The maximum of value of sash
cycles is 16000. The cycles will raise every sash move to up and down.
Warning message will be showed after the cycle value reach 15000.
1st warning: “Replace Sash Motor” – after sash reached 15000 cycles.
2nd warning: “Stop Using Sash” - after sash reached 15500 cycles.
3rd warning: “Sash Motor Locked” (Sash motor cannot operate anymore) - after sash reached 16000 cycles.

2.3 Stopwatch and Experiment Timer (only for non-motorized sash BSC)

The stopwatch function can be started by pressing the UP button while the sash is in the safe/ready
position. Pressing UP button again while the stopwatch function will stop and resume the timer.
Pressing DOWN button will leave the stopwatch function and reset the timer. The timer in the
stopwatch function is counting up and shown using the HH:MM:SS format.

The experiment timer can be started by pressing the DOWN button while the sash is in the safe/ready
position. Pressing DOWN button while the experiment timer function is working will stop and resume
the timer. Pressing the UP button will leave the experiment timer function and reset the timer. The
timer in the experiment timer function is counting down and shown using the HH:MM:SS format.
Operator can use the SETTINGS | EXPERIMENT TIMER menu (refer to section 2.2.1.4) to set the
experiment timer.
2.4 Alarms and Warnings
BSC uses alarms to indicate that the condition inside the BSC is not safe for the operator, so check the LCD
display to understand the cause of these alarms. The most common alarm is the SASH ALARM that indicates
that the sash is neither at the normal operating height nor at fully closed position (UV mode) – this condition
can easily be corrected by putting the sash at the appropriate operation position.
Another warning that should be acted upon is AIR FAIL! which indicates that there is airflow failure. The
operator should check if there is any obstruction to the airflow, and correct it if possible. However, if the
problem continues, the operator should stop working as the BSC’s protection may have been compromised.
Call service or Esco’s local distributor.
Other alarms that indicate a failure or an error in the BSC system:

AIRFAIL:NO! will be displayed if the blower is turned off while there is an airflow failure.

SASH:ERROR POSITION will be displayed if the microprocessor (controller) detects more than one
micro-switch activated at the same time, which is impossible, as the sash can only be at one position
at one time. This indicates a failure in the sash detection system.

SENSOR UNCALIBRATED will be displayed if the airflow velocity sensor is not yet calibrated.
