TWIN SYSTEM- HEED SAFETY INSTRUCTIONS!

Outputs
"Malfunction" and
"warning"
5.4 Checks
- on the setting of the motor protection switches
The motor protection switches must be set to the
values for rated current of the respective pumps
as specified in section 3.
5.5. Configuration of switch unit (from model year 01/10)
The DIP switch is located at the top right of the PCB in the switch unit and has four setting possibilities
1. Switch: Sensor selection
2. Switch: Level heights
3. Switch: Configuration tables (only for service partners)
4. Switch: Anti-blocking system

5. Electrical connections
Switch unit
from model year 01/10
• The "malfunction" and "warning"
messages are issued via a relay
(changeover contact) without
protective circuit. Inductive loads
must be dejammed externally.
The quiescent state (current-
less) of the relays is printed on
the board. It means "malfunc-
tion" and "warning" message is
switched on.
42 V dc/ 0,5 A
- Switch up: Level measurement using float switcher
- Switch down: Level measurement using air pressure switch
- Switch up: Underground pumping stations (with submersible pumps)
- Switch down: Lifting stations (using air pressure switch)
- Switch up: Anti-blocking system off
- Switch down: Anti-blocking system on

up to model year 12/09
• The terminals are marked with switch symbols.
• The "malfunction" and "alarm" messages are is-
sued via a relay (changeover contact) without
protective circuit. Inductive loads must be de-
jammed externally. The quiescent state (current-
less) of the relays is printed on the board. It
means "malfunction" and "alarm" message is
switched on.
• The relay contacts do not have any internal connec-
tion to any kind of supply or operating voltages of
the control unit and are safely separated from these
up to a working voltage of 300 V according to Table
•
D.10 of the standard EN 61010 (excess voltage ca-
tegory 2 and degree of soiling 2).
• The relays have been designed for switching 230 V
/ 2 A. Suitable measures must be taken to restrict
the current externally to this value.
• The relays must not be used to switch different pha-
ses. The phase may deviate from L1 however.
