Configuration

This option controls the basic configuration of the fume cupboard; it can only be accessed with a

password. Its main use is during setup and commissioning of the cupboard and or maintenance or

trouble shooting. The features available behind this option are not described here. Please refer to

the setup and configuration manual.

Backlight

This option controls the intensity of the display backlighting. In many cases this is a personal choice

and can be changed at any time.

Setting the backlight

1. Press "FUNCTION" button to enter Setup.

2. Press "BLIGHT (BOOST)" button to enter clock and timers setup.

3. Use the "UP (FAN)" or "DN (BOOST)" Buttons to set the desired intensity.

Should a mains failure alarm occur, then the back light intensity will default to the lowest level to

conserve battery power. This cannot be overridden during the alarm.

Alarms

The Dynasafe® Control System MK5 Fume cupboard controller monitors several inputs to

ensure operation remains within nominal specifications.

Emergency Isolator

Located on the front panel, this switch will cause the fume cupboard to shut down and isolate all

electrical and gas services.

To restore operation twist and release the emergency isolator switch.

Mains Failure

Indicates electrical power failure. Batteries will allow operation of the controller for minimum 20

minutes from power failure.

Low Battery

This will occur if there is a fault with the backup batteries or the controller has been running on

battery power and the battery voltage has dropped below the preset threshold. It signals the

possible shutdown of the control panel if mains power is not restored soon. Panel will resume

normal operation once power has been restored.

Low Air Flow

When the airflow within the exhaust duct drops below the preset threshold, an alarm will occur.

Electrical and gas services are isolated until the airflow problem has been corrected.

High Sash Alarm

If the Sash is lifted above a predetermined height for more than a period of time (Adjustable), an

alarm will be sounded until either muted or the sash is lowered. This is used as a power saving

device and can be turned off or on during commissioning.
