Electrical Connection

WARNING!
Before maintenance or repair of pumps
switch off their power supply.
Consider the safety instructions (page 5
and 6)!
4273a 00
CAUTION!
Before starting, make sur e that the general
power supply is off. The device must never
be connected or disconnected when the
power is on. The protective conductor must
always be c onnec ted. Take care that this
line section is undamaged and conform s to
standards and the contacts are safe.
NOTE
The protection IP6K9K is guaranteed when
the socket ( X1:, X2: & X3:) is tightened on
the housing cover with flat packing.

NOTE
Consider the contact protection measures
for c onnecting the high- or low-level control
(see chapter "Mode of Operation" / para-
graph „Low- or High-level Control").
Make s ure of the connection and the type of construc tion
of your QLS 401.
- type of connection (VDC / VAC)
- low-level indication
- type of connection plug
- monitoring of metering device via external or internal
cycle switc h
Connect the electrical wires according to the following
electrical connecting diagrams (see chapter „Technical
Data").

Printed Circuit Boards

IMPORTANT
Whenever the pump housing has been
opened (e. g. for replacing of the p.c.b.), the
housing cover (including the foamed seal)
must be replac ed.

Operation with bayonet plug

CAUTION!
If the protective-conductor terminal is not
connected or interrupted, dangerous touch
voltages may occur on the equipment!
4273a 00
Protective measures to be applied for appropriate operation
with bayonet plugs :
"Functional extra-low voltage with safe is olation" /
"Protective Extra-Low Voltage" (PELV)
Standards :
EN60204 Part1:1992 / IEC 204-1:1992, modified
DIN VDE 0100 Part 410 / IEC 364-4-41:1992
ATTE NTION!
Pumps are connected to 110-240 V AC if
required. However, printed circuit board
and motor always operate at 24 VDC.
Consider residual ripple of max.
when connec ting motor and control p.c.b.
4273a0 0
(in relation to the operating voltage acc. to
DIN 41755).
Disassem ble defective control p.c.b.
Note down the jum per positions of the defective control
p.c .b. To do so, follow instructions given in paragraph
„Jumper Configuration".
Pack the defective control p.c.b. properly so that it will
reach the factory without any further dam ages.
In the case of a replacement of the contr ol p.c.b., there will
always be supplied a standard version (V10) of the p.c.b.
Set the jum per configuration on the new control p.c.b.
according to the one noted down from the old control p.c .b.
Connect the new control p.c.b. and install it properly.
