See wiring diagram SS-1121/1122, Pt 10.
6.4.8 Connection: External switching contact to ALB with electric heater
See wiring diagram SS-1123/1124, Pt 9.
6.4.9 Connection: Warm water heating
Potential-free switching contact, see wiring diagram SS-1121/1122, Pt 14.
6.4.10 Connection: Indication of operating state
Potential-free switching contact, see wiring diagram SS-1121/1122, Pt 15 and SS-1123/1126, Pt 13.
6.4.11 Connection: Temperature sensor extract air unit
See wiring diagram SS-1125/1126, Pt 2 in the ALB-AS.. extract air unit installation and operating instructions.
6.4.12 Connection: Modbus interface
See wiring diagram SS-1121/1122 Pt 13, wiring diagram 1123/1124, Pt 12.
An open communication protocol will be provided as a document, necessary peripherals must be provided by the customer.
6.5 Commissioning
WARNING!
The rotating impeller can crush/scrape fingers.
Ensure protection against contact before commissioning!
The following inspection work must be carried out or checked before commissioning:
– Check designated use of the ALB.
– Check permissible transport media temperature.
– Compare mains voltage to rating plate data.
– Check ALB for professional electrical installation.
– Check the waterproofing of the connection cable and tight clamping of the strands.
– Check protective conductor connection.
– Check all parts for tightness, particularly screws, nuts, protection guards. Do not loosen screws in the process!
– Check ALB for solid mounting! Terminal box / isolator switch and motorised impeller unit must be freely accessible.
– Ensure that the suction and outlet areas cannot be accessed by unauthorised persons.
– Check tightness of all connections (if necessary).
– Remove assembly residues from the fan or duct.
– Check free movement and direction of rotation of impeller; wear protective glasses when checking.
– Intake-side check valve must be accessible.
– Compare power consumption to rating plate data.
– Check ALB for vibrations and noises during test run. Check ALB for vibrations and noises during test run. In case of
excessive vibrations and/or noises, operation outside of the operating range of the ALB is to be assumed. In this case,
it is imperative that the manufacturer is contacted!
– Do not operate the ALB outside of the specified characteristic curve (see catalogue/internet). The ALB must run at
its prescribed operating point.
– By turning the main inspection switch to position 1, the fan will switch to standby mode.
The unit is switched on by pressing the touch screen.
6.6 Commissioning the ALB with a warm water heater battery
The mixing node (wiring diagram SS-1121/1122, Pt 9) is partly opened by the commissioning of the ventilation unit.
The water pump is activated if the heating flow is used by the pump control (wiring diagram SS-1121/1122, Pt 17). The
intake and outlet flaps also open (accessory; by client) (wiring diagram SS-1121/1122, Pt 16) and the fan will activate.
When the ALB is switched off, the fan will switch off first, the flaps will close and the water pump will switch off last.
The mixer will not be closed, it will stay in position. The ALB will be heated by the warm water heater battery. If the frost
protection is activated, the unit will immediately switch the fan off and the flaps will close. The mixing node will open to
ensure the water flow through the heat exchanger.
