Crouzet has announced a new burner management unit, certified to EN 298 for forced draft burners, that uses electronics to provide powerful trip analysis and indication.
The microprocessors built into the new CGG1&2 provide detailed maintenance diagnostics; by pressing the red trip button for 3 seconds, service engineers will obtain a readout of trip type signalled by coded flashes of the trip button light.
Knowing which of the many possible causes resulted in the burner trip will give service teams a great advantage in efficiency and quality of service.
The fault code is then reset by operating the button a second time.
The CGG1&2 also deliver high accuracy timings, a remote reset option and a greatly reduced footprint compared to electro-mechanical devices.
Unlike conventional units, the CGG1 and 2 also implement the safety critical functions using two microprocessors, one monitoring the other.
Using microprocessors allows the unique reduction in size, improvement in accuracy and flexibility of timings.
The CGG1 burner management unit provides the usual purge, pilot gas valve control, ignition control, main gas valve control and flame monitoring required by forced draft burners.
In addition, the CGG2 model provides an air flap controller.
