Signal word Meaning

WARNING Denotes a possibly dangerous sit‐

uation. If this is disregarded, you

are in a life-threatening situation

and this can result in serious inju‐

ries.

CAUTION Denotes a possibly dangerous sit‐

uation. If this is disregarded, it

could result in slight or minor inju‐

ries or material damage.

The following warning signs are used in these operating instructions to

denote different types of danger:

n The pump may only be started up after it has been correctly installed

and started up in accordance with the technical data and specifica‐

tions contained in the operating instructions.

n Observe the general limitations with regard to viscosity limits, chem‐

ical resistance and density - see also ProMinent resistance list in the

WARNING!

Warning about personal and material damage

The pump can start to pump, as soon as it is connected

to the mains voltage.

– Install an emergency cut-off switch in the pump

power supply line or integrate the pump in the emer‐

gency cut-off management of the system.

WARNING!

Warning of personal injury and material damage

The pump can start pumping as soon as it has cooled

down after the error

‘temperature’

.

– Take this into account with the pump and your

installation.

WARNING!

Danger of electric shock

A mains voltage may exist inside the pump housing.

– If the pump housing has been damaged, you must

disconnect it from the mains immediately. It may

only be returned to service after an authorised

repair.

WARNING!

Warning of hazardous feed chemical

Should a dangerous feed chemical be used: it may

escape from the hydraulic components when working on

the pump, material failure or incorrect handling of the

pump.

– Take appropriate protective measures before

working on the pump (e.g. safety glasses, safety

gloves, ...). Adhere to the material safety data sheet

for the feed chemical.

–

Drain and flush the liquid end before working on the

pump.

WARNING!

Fire danger

The pumping of flammable media is prohibited.

WARNING!

Danger from hazardous substances!

Possible consequence: Fatal or very serious injuries.

Please ensure when handling hazardous substances

that you have read the latest safety data sheets provided

by the manufacture of the hazardous substance. The

actions required are described in the safety data sheet.

Check the safety data sheet regularly and replace, if

necessary, as the hazard potential of a substance can

be re-evaluated at any time based on new findings.

The system operator is responsible for ensuring that

these safety data sheets are available and that they are

kept up to date, as well as for producing an associated

hazard assessment for the workstations affected.

Safety information

CAUTION!

Warning of feed chemical spraying around

Feed chemical can spray out of the hydraulic compo‐

nents if they are manipulated or opened due to pressure

in the liquid end and adjacent parts of the system.

– Disconnect the pump from the mains power supply

and ensure that it cannot be switched on again by

unauthorised persons.

–

Depressurise the system before commencing any

work on hydraulic parts.

CAUTION!

Warning of body parts being drawn in

The rotor running in the liquid end may draw in and trap

body parts.

– Do not reach into the running rotor.

–

Only take off bearing cover once prompted to do so

by the operating instructions or operating software.

CAUTION!

Warning of feed chemical spraying around

An unsuitable feed chemical can damage the parts of

the pump that come into contact with the chemical.

– Take into account the resistance of the wetted mate‐

rials and the ProMinent Resistance List when

selecting the feed chemical - see the ProMinent

Product Catalogue or visit ProMinent.

CAUTION!

Warning of feed chemical spraying around

An unsuitable feed chemical may cause premature wear

to the pump hose.

– Observe the pump hose's resistance and "Chemical

Resistance List DFXa" available at www.promi‐

nent.com when selecting the feed chemical.

CAUTION!

Danger of injury to personnel and material damage

The use of untested third party components can result in

injury to personnel and material damage.

– Only fit parts to metering pumps that have been

tested and recommended by ProMinent.

CAUTION!

Danger from incorrectly operated or inadequately main‐

tained pumps

Danger can arise from a poorly accessible pump due to

incorrect operation and poor maintenance.

– Ensure that the pump is accessible at all times.

–

Adhere to the maintenance intervals.

Safety chapter

11

CAUTION!

Warning against illegal operation

Observe the regulations that apply where the device is

installed.

n Cover for the slot for relays and optional modules - see the chapter

entitled "Overview of Equipment and Control Elements"

n Bearing cover for liquid end - see "Overview of equipment and control

elements” chapter

Customers should only remove the cover for the slot for relays and

optional modules and/or a relay or optional module in line with the supple‐

mentary instructions for the relays and optional modules.

Customers should only remove the bearing cover for the liquid end in

accordance with the "Repair" chapter.

Only the ProMinent service department is authorised to open the housing

and hood (housing the control elements).

Adhesive labels

WARNING!

– A warning sign indicating "Warning of injury to

hands" is stuck on the pump and warns of rotating

parts and the risk of being drawn into the liquid end.

–

Ensure that the label is always fitted and legible.

In an emergency, either disconnect the mains plug, press

[Start/Stop]

or press the Emergency Stop switch installed on the customer's side or

disconnect the pump from the mains/power supply in line with the Emer‐

gency Stop management guidelines for your system.

If feed chemical escapes, also ensure that the pump's hydraulic environ‐

ment is at atmospheric pressure. Adhere to the material safety data sheet

for the feed chemical.

6 Functional description

6.1

Device

An electric motor drives a rotor. Rollers are fitted to the ends of the rotors,

which press the pump hose against the inner curvature of the dosing

head. The peristaltic pump operates by the rollers driving the feed chem‐

ical through the pump hose. The feed chemical is primed by the pump

hose automatically returning to its initial position.

6.2 Capacity

The capacity that has been set regulates the pump itself.

6.3 Operating modes

Operating modes are selected via the "Operating modes" menu.

Refer to the "Hierarchy of Operating Modes, Functions and Fault Statuses"

for the order of the various operating modes, functions and fault statuses.

‘Manual’

operating mode permits you to operate the pump manually.

This operating mode provides the option of controlling the pump externally

by means of potential-free contacts (e.g. by means of a contact water

meter). “Pulse Control” can be used to preselect the metering volume in

the

‘Settings’

menu.

This operating mode provides the option of working with large metering

volumes. Metering can be triggered either by pressing the

[Clickwheel]

or

by a pulse received via the "External control" terminal via a contact or a

semiconductor switching element. It is possible to pre-select a metering

volume (batch) and a metering time using the

[Clickwheel]

in the

‘Settings’

menu.

The capacity is controlled using an analogue current signal via the

"External control" terminal. Processing of the current signal can be prese‐

lected using the control unit.

6.4 Functions

Refer to the "Hierarchy of Operating Modes, Functions and Fault Statuses"

for the order of the various operating modes, functions and fault statuses.

The following functions can be selected using the

‘Settings’

menu:

"Manual" operating mode

"Contact" operating mode

"Batch" operating mode

"Analog" operating mode
