34.1 Basic
design
The RVD230 is comprised of controller insert, which accommodates the electronics, the
power section, the output relays and – on the front – all operating elements, and the
base, which carries the connection terminals.
The RVD230 contains 9 relays
The operating elements are located behind the cover. On the inner side of the cover,
there is a holder in which the Operating Instructions can be inserted. When the cover is
closed, only the LCD and the LED for manual operation are visible. The setpoint knob
is located beside the cover.
The RVD230 has the standard overall dimensions 96 mm × 144 mm.
It can be mounted in one of three different ways:
•
Wall mounting
•
Rail mounting
•
Flush panel mounting; the front panel may have a maximum thickness of 3 mm
Whichever mounting method is chosen, the base must always be mounted and wired
first. To ensure the orientation will be correct, the upper side of both the base and the
controller housing carry the marking TOP. Both the top and the bottom side of the base
have 5 knockout holes for cable entry; there are 10 knockout holes in the floor.
The controller insert plugs into the base. It has 2 screws each of which is fitted with a
lever. When, after fitting the controller insert, the screws are tightened, their levers
engage in the openings in the base. When the screws are further tightened (alter-
nately), the controller pulls itself into the base. The controller insert is thus secured to
the base; at the same time, the electrical connections between controller insert and
base are established.
