Power supply
Provide an external power fuse.
For 115 or 230 V power voltage: Connect L1 conductor
to terminal »115« or »230«, respectively. Connect N
conductor to terminal »N«.
For 42 V power voltage: Connect L1 conductor to
terminal »42«. Connect N conductor to terminal »0«.
Connect the protective earth (PE) conductor to the
terminal in the unit head.
WARNUNG: Internally generated power voltage
The power terminals »230« and »115« will have a voltage
output of 230/115 V, even if the unit is used with a lower
power voltage (due to power feedback through internal
transformer).
Observe this information when operating the unit with
open unit head for service purposes. Take care. Give a
warning to other persons.
Permissible power voltage tolerance: –15 %/+10 %
Internal fuses
Type 220 is equipped with three internal fuses:
● Power overload fuse: see type 220.
Overheat fuse: see type 220.
●
● Overheat fuse in the power transformer: cuts off the
transformer circuit at 98 °C (208 °F).

1 Fail-safe FULL indication:
K1 is activated when the
paddle is rotating. During
power failure, the »full«
status is indicated (like
paddle is stopped).

switches on with a delay of
4 s.

Closing the cable glands

3.6.1
Lay the connected cables internally in such a way that
they do not interfere with the mechanism.
After the cables have been installed, the cable glands
must be closed-off to be dust-tight and spray-water
resistant.
Unused cable glands must either be blocked-off with
stoppers or replaced with closing caps. If used in
explosion-hazardous
applicable
certified).

Closing the cover

3.6.2
Before closing cover of the unit head, check whether
there are any foreign bodies inside the unit head (such as
rests of cable). Remove them.
Visually check the sealing of the cover. Clean or replace if
necessary.
Put the cover in place and screw it up tight.
OFF
Fail-safe
EMPTY indication: K1 is
activated when the paddle
is stopped. During power
failure, the »empty« status
is indicated (like paddle is
rotating).

No electronic switch-off
delay.
