OPERATING PRINCIPLE
The TYPE A controller is used to control the ventilation of a fixed air flow fume cupboard.
It has three push buttons, allowing you to control ventilation, lighting, and stop the audible alarm.
Pressing the M/A ventilation button on the HMI allows you to control an extractor and/or a motorized shutter via the two VENT 1 and VENT 2 relays.
The probe measures the frontal velocity and the controller informs the user using several LEDs.
The green LED is on when the face speed is sufficient.
The red LED flashes when the face speed is insufficient.
The orange LED "sash overhang" lights up if the maximum window height is exceeded. This fault is triggered by a position switch.
The orange “auxiliary faults” LED lights up if the auxiliary input is activated.
The audible alarm is activated after a delay of 15 to 30 seconds when a fault remains present. After identifying the cause, the user can silence this alarm by pressing the buzzer stop button.
Pressing the light ON/OFF button controls the lighting via a 250V 16A relay.
The controller is powered by a supplied 230V/12V transformer.
The controller is factory preset to 0.5m/s and can be adjusted on site using an anemometer
