Variable air flow controller 2 speeds version with remote control panel
REF 819756
REF 819754 (display option)
Tutorial Type C2V Remote Quick Setting (ENG)
The TYPE C 2-speed remote HMI controller is a safety device that regulates the airflow according to a low and high speed depending on the sash position.
The controller engages the second speed by means of a switch placed on the sash path. It informs the user with visual and audible alarms if a malfunction occurs. The remote HMI enables adjustments on site and controls the fume hood ventilation.

OPERATING PRINCIPLE
The TYPE C 2-speed remote HMI flow controller controls the airflow of a fume hood.
Three push buttons are used to control the ventilation, the lighting and to stop the alarm.
Pressing the ON/OFF ventilation button on the HMI controls a fan and/or a motorised damper via the two relays VENT 1 and VENT 2.
It allows to regulate the ventilation according to 2 operating points determined by the position of the sash.
• In the low position, the controller sends a first fixed voltage.
• In high position, the controller sends a second fixed voltage.
The switch allows to alternate from one speed to another. The controller ensures both the safety of the operator and an important energy saving.
The green LED is lit when the face velocity is sufficient.
The red LED flashes when the face velocity is insufficient.
The orange «sash overrun» LED lights up if the sash is raised above the maximum safe working opening. This fault is triggered by a position switch.
The orange LED «auxiliary faults» lights up if the auxiliary input is activated.
If a failure remains within a period of time of 15-30s, the audible alarm will activate. Having identified the problem, the laboratory personnel can stop the alarm by pushing the stop buzzer button.
Pressing the light ON/OFF button controls the lighting via a 250V 16A relay.
The controller is supplied with a 230V/12V power adaptor.
The controller is factory preset to 0.5m/s and can be reset on site using an anemometer.
