1. Applications

The CU 401 control unit is designed for the monitor-

ing and control of a number of Grundfos pumps.

Optimum pump operation is thereby ensured.

The CU 401 unit is the "brain" of a main control sys-

tem.

The CU 401 unit can be used alone or together with

various modules which can be connected as

required.

The number of pumps that can be monitored and

controlled depends on the modules in the system.

Prior to installation, read these installation

and operating instructions. Installation and

operation must comply with local regula-

tions and accepted codes of good prac-

tice.

All wires to units outside the control panel

must be of the type H05VV-F according to

CENELEC HD21 (to avoid injury from

touching wires).

3. Mounting

For EMC reasons, the mounting plate must be made

of an electrically conducting material, e.g. iron.

The two mounting forks, one on each side of the

locking screw, must be fixed, e.g. with self-tapping

screws.

Place CU 401 in a closed control panel so that

access is only possible by means of tools or a key.

Hand out keys only to professional or specially

trained staff.

TM02 7129 2703

The CU 401 control unit must be mounted on a 35 mm stand-

ard DIN rail (EN 50022). Recommended height 7.5 mm.

The size of the unit appears in section 16. Dimensions.

All dimensions are stated in mm.

Note:

• Place the CU 401 unit so that there is sufficient space to

mount a modem, CompactFlash card and communication

bus.

• Place the CU 401 unit to the left of the expansion modules.

• Terminator, see section 9. Terminator.

• Fit the internal battery (supplied in separate packaging)

before the CU 401 unit is mounted on the DIN rail.

TM02 6667 1303

• Mount the CU 401 unit by first hooking the top of the unit to

the DIN rail and then the bottom.

TM02 7135 2703

• Fit the terminals and turn the locking screw to position

"locked".

Use a 6 mm screwdriver for slotted screws.

TM02 7133 2703

• If the modules are mounted vertically, it is recommended to

fit the end stops supplied to the DIN rail, i.e. below the low-

est module.

TM02 6670 1303

• Check the hardware when all modules have been mounted

and the power supply has been switched on. The indicator

light (P) must be green.

Note: If the CompactFlash card has been inserted, the module

mode will change according to the loaded program.

5.1 Inputs

Pulse counter input

Analog inputs

All analog inputs are short-circuit protected.

Digital inputs

The digital inputs are activated by short-circuiting the

input concerned to 0 V, e.g. with a contact or a relay.

The pulse counter input, digital inputs and analog

inputs have the same minus potential. The inputs are

not isolated from each other.

Supply 24 V ±7%

Note: The supply module PU 101 must only be used

for the CU 401. If the PU 101 is used for other pur-

poses, e.g. sensor supply, the galvanic separation

will be ignored.

7.1 UPS battery back-up

The CU 401 unit can be connected to an emergency

supply, i.e. UPS battery back-up (UPS – Uninterrupt-

ible Power Supply), via the PU 102 module. The

emergency supply time depends on the battery size.

The battery is automatically charged as long as the

CU 401 unit is supplied with 24 V.

An indicator light on the CU 401 front shows "battery

OK". The charging state is indicated on the PU 102.

For further information, see installation and operat-

ing instructions for the PU 102.

7.2 GENIbus (RS-485)

The GENIbus is a Grundfos standard using an

RS-485 interface. The GENIbus is used for several

Grundfos products.

Detailed documentation about the GENIbus can be

requested from Grundfos.

7.3 IR communication

The CU 401 unit is prepared for the Grundfos remote

control R100.

For further information, see installation and operat-

ing instructions for the CompactFlash card.

7.4 Operator display (OD 401)

Grundfos operator display for CU 401, see installa-

tion and operating instructions for the OD 401.

7.5 Communication to PC (RS-232)

Communication port for PC Tool. For connection to

the port, see "RS-232 input" in section

5.3 Terminals.

TM02 6668 1303

The module bus is the electrical connection between the

modules. Up to 12 modules can be connected.

The total current consumption must not exceed

• 2 A at 24 V and

• 1.5 A at 5 V.

See installation and operating instructions for the module in

question.

1. Sicherheitshinweise

1.1 Allgemeines

Diese Montage- und Betriebsanleitung enthält grund-

legende Hinweise, die bei Installation, Betrieb und

Wartung zu beachten sind. Sie ist daher unbedingt

vor Montage und Inbetriebnahme vom Monteur

sowie dem zuständigen Fachpersonal/Betreiber zu

lesen. Sie muss ständig am Einsatzort der Anlage

verfügbar sein.

Es sind nicht nur die unter diesem Abschnitt "Sicher-

heitshinweise" aufgeführten, allgemeinen Sicher-

heitshinweise zu beachten, sondern auch die unter

den anderen Abschnitten eingefügten, speziellen

Sicherheitshinweise.

1.2 Kennzeichnung von Hinweisen

Direkt an der Anlage angebrachte Hinweise müssen

unbedingt beachtet und in vollständig lesbarem

Zustand gehalten werden.

1.3 Personalqualifikation und -schulung

Das Personal für Bedienung, Wartung, Inspektion

und Montage muss die entsprechende Qualifikation

für diese Arbeiten aufweisen.

Verantwortungsbereich, Zuständigkeit und die Über-

wachung des Personals müssen durch den Betreiber

genau geregelt sein.

1.4 Gefahren bei Nichtbeachtung der

Sicherheitshinweise

Die Nichtbeachtung der Sicherheitshinweise kann

sowohl eine Gefährdung für Personen als auch für

die Umwelt und Anlage zur Folge haben. Die Nicht-

beachtung der Sicherheitshinweise kann zum Ver-

lust jeglicher Schadenersatzansprüche führen.

Im einzelnen kann Nichtbeachtung beispielsweise

folgende Gefährdungen nach sich ziehen:

• Versagen wichtiger Funktionen der Anlage

• Versagen vorgeschriebener Methoden zur War-

tung und Instandhaltung

• Gefährdung von Personen durch elektrische und

mechanische Einwirkungen.

1.5 Sicherheitsbewusstes Arbeiten

Die in dieser Montage- und Betriebsanleitung aufge-

führten Sicherheitshinweise, die bestehenden natio-

nalen Vorschriften zur Unfallverhütung sowie even-

tuelle interne Arbeits-, Betriebs- und Sicherheits-

vorschriften des Betreibers, sind zu beachten.

1.6 Sicherheitshinweise für den Betreiber/

Bediener

Gefährdungen durch elektrische Energie sind aus-

zuschließen (Einzelheiten hierzu siehe z.B. in den

Vorschriften des VDE und der örtlichen Energiever-

sorgungsunternehmen).

Die in dieser Montage- und Betriebs-

anleitung enthaltenen Sicherheitshin-

weise, die bei Nichtbeachtung Gefähr-

dungen für Personen hervorrufen kön-

nen, sind mit allgemeinem Gefahren-

symbol "Sicherheitszeichen nach

DIN 4844-W9" besonders gekennzeich-

net.

Dieses Symbol finden Sie bei Sicher-

heitshinweisen, deren Nichtbeachtung

Gefahren für die Maschine und deren

Funktionen hervorrufen kann.

Hier stehen Ratschläge oder Hinweise,

die das Arbeiten erleichtern und für

einen sicheren Betrieb sorgen.
