ASH REMOVAL
The cable used to connect the ash removal system motor shall have
the cross-section specified in table 1. Ash-removal motor winding
shall be connected according to the diagram located inside the
connection box.
Fig.18. Identification of connecting terminals.
Power supply of the ash removal motor shall be connected to terminals shown
on figure 18. The protective wire shall be connected to a terminal of the PE
terminal strip (9) (fig. 7). After the motor is connected, it is necessary to check
form worm shaft rotation direction. The worm shaft shall rotate in the direction
causing ash to be pushed off into the container. If this is not the case, then it is
necessary to change motor wiring connections.
The ash removal system is standard feature in AZSB 100 GC,
AZSB 120 G
Ż
, AZSB 240 GC and G
Ż
units.
MIXING VALVE ACTUATOR
The mixing valve actuator shall be connected to the terminal
strip (8) (fig. 7) terminals identified with the symbol shown on
figure 19. The protective wire shall be connected to a terminal
of the PE terminal strip (9) (fig. 7). The recommended cross-
section of the actuator’s connecting cable is stated in table 1.
Fig.19. Identification of connecting terminals.
The actuator supports only mixing valve servos equipped with limit switches.
Use of other mixing valve servos is not allowed. One may use actuators with the
full rotation time between 30 and 255s.
Detailed information regarding connection and configuration of the controller to
support the mixing valve actuator can be found in the controller operating
instructions, enclosed with the boiler.
BOILER TEMPERATURE SENSOR
The boiler temperature sensor shall be connected to the supply pipe as shown on
fig. 15a and connected to terminals no. 16 and 17 of the controller, which are
identified with the symbol shown on figure (fig. 20). In order to extend the
sensor cable, one may use a cable with cross-section stated in table 1, which
does not exceed 10 m in length, as this may adversely affect temperature
readouts accuracy. Installation of sensor cable along power supply lines shall be
avoided. It is necessary to maintain at least 10 cm spacing.
