TECHNICAL INFORMATION
NUMBER 003/2006
Technical change: SENSOR OF REVOLUTIONS OF THE FEEDER 1 A P 2 - TYPE: EA 198
Properties achieved:
The sensor is a replacement for the sensors of revolutions used so far - induction probes. It is designed to check rotation
of the shaft of the feeder P 1 or P 2. Each sensor is equipped with an independent connector. Universality during
installation and service is thus ensured.
The following has been added to the electric equipment of the boiler:
- 2 x connector CANNON 9 FEMALE placed on the subpanel on the rear side of the boiler - see the figure number
Ti001/1.
- Interconnection of the connector with the control unit - see the figure number Ti001/3.
- Sensor of revolutions
EA 198.
Mechanical arrangement:
The disc with permanent magnets is fastened by means of the screw M8 on the shaft of the gear box with the
aluminium part of the disc towards the head of the screw. Any clearance between the face of the shaft and the flange
of the gear box has to be limited with a corresponding washer in order to prevent from any deformation of the disc
when the screw is tightened. Two distance columns OK 10x20 shall be screwed on the face of the gear box on which
the cover of the sensor with electronics will be fastened by means if 2 screws M 6x10 with washers 6.2.
The sensor is equipped with a non-detachable cable with the connector CANNON 9 MALE.
One sensor is used for every feeder.
Figure number Ti003/1
Description of operation:
If the shaft is rotating, the sensor generates 6 pulses per one revolution and thus indicates to the control unit of the
boiler correct operation of the screws of feeders and thus prevents from undesirable fuel filled in the connecting plastic
hose of the feeder 2.
SW modification:
NO
Note:
Correct connection of the sensor is indicated in idle state with constant light of the red LED on
the casing of the sensor, rotation of the shaft is then indicated by oscillating light of the LED.
Note:
REVOLUTION SENSOR OF THE FEEDER
1, 2 - TYPE EA 198 is a part of deliveries of the boilers from
the serial number 291/2006 on and supersedes the induction sensors used so far and thus improves reliability
of the product.
