Electrical Installation - Siemens RLM162 Instructions D'installation

In the supply air duct downstream from the supply air

fan if fan is installed after the last air handling unit,
otherwise
In the supply air duct downstream from the last air

handling unit in a distance of 0.5 m
 As a minimum supply air temperature limiter:
In the supply air duct as close as possible to the air dis-
charge into the room
 As a dewpoint controller:
Immediately downstream from the droplet separator of
the air washer
Mounting
Procedure:
1. First mount the flange. For drilling holes, refer to "Di-
mensions".
2. Bend flexible sensing element manually (never use a
tool) so that – when mounted – it stretches diagonally
across the air duct .
Note! The flexible sensing element may not touch the
duct wall: The minimum clearance is 50 mm and the
smallest permissible bending radius 10 mm
3. Fit mounting flange.
4. Slide controller on mounting flange and snap it on.

Electrical installation

 Ensure that the local regulations for electrical installa-
tions are complied with
 The connecting terminals are located under the flexible
plastic cover
 Make wiring according to the plant documentation. If not
available, use the connection diagrams contained in
these Installation Instructions
 Observe the permissible cable lengths
 Switch on power only when commissioning the controller
 External preliminary protection with max. C 10 A circuit
breaker is required in all cases

Indication of operating state
The red LED indicates the controller's operating state:
 LED lit: Mains voltage present
 LED flashes: In test mode
The LED is also visible when the cover is fitted.
Commissioning
When used as a controller
1. Remove housing cover.
2. Lift flexible plastic cover so that you can access the
setting elements.
3. Make the settings:

Control mode and (with PI mode) integral action

time (DIP switches 3 and 4)
