3.3

Special features in the active PROFIBUS

mode

3.3.1 General

The pump cannot be manually set or programmed

in PROFIBUS

mode. To do this, set the PRO‐

FIBUS

to ‘inactive’ .

n The

[Clickwheel]

can be used to switch between the contin‐

uous displays at any time, as in the other operating modes.

This does not affect the operation of the pump.

n When PROFIBUS

mode is selected, the settings from the last

operating mode without PROFIBUS

are applied. However,

settings made using the PROFIBUS

are not saved! They only

apply as long as the pump is connected to the PROFIBUS

Only the

‘stroke counter’

(total number of strokes) and the

‘rotation counter’

(total number of rotations), depending on the

pump design, and the

‘quantity counter’

(total number of litres)

continue to be counted and saved.

n The pump stops when it is switched to PROFIBUS

mode. The

pump can be reactivated by pressing the

[Stop / Start]

key.

Use the BUS to give the Start command.

3.3.2 Displays

There are additional identifiers in the operating display when PRO‐

FIBUS

mode is running.

INFORMATION!: The commonly used identifiers can be found in

the “Control elements” chapter in the "Operating instructions

for the peristaltic metering pump DULCO flex Control, DFXa".

PROFI

BUS

PROFIBUS

stop: the pump has been stopped using PRO‐

FIBUS

. The master has sent the pump a corresponding telegram.

Manual stop: the pump has been stopped using the

[Start / Stop]

Connection error: If the pump loses its connection to the PRO‐

FIBUS

(as soon as the BUS cable is removed or the bus master

becomes inoperative,

for example), the error symbol

and the

symbol appear.

Error module: If the pump loses its connection to the BUS

module (as soon as the BUS module is removed or if communica‐

tion between the BUS module and pump is interrupted for other

reasons, for example), then the error symbol and the symbol

appear.
