Electrical connection of A•monitor shown with A•smoke40
The electronic pressure monitor is delivered factory preset and contains the following features:
Optical display of the pressure drop over the filter stages
The present pressure drop over each filter stage is monitored.
Hour counter device
An hour counter device is also included in our standard equipment. It shows the total operation time of the filter unit measured in hours.
A green LED lamp is lit as long as the filter cassette works within the preset pressure range. When the yellow lamp lights up, the filter stage needs to be replaced or washed. Call your service contact for advice. When the red LED lamp lights up, the pressure drop over the filter stage is too high, and the filter unit might give a reduced air flow.
On the transformer circuit, there is an alarm output that can be used for external alarms (maximum 1A). If any of the filter stages reaches alarm level (red LED), the alarm output closes.
