8.7.43 Reduced operation (4.3.24)

Fig. 93

Reduced operation

Description

This function makes it possible to limit the number of pumps in 
operation, or for MPC-E systems, to limit power consumption. 
The limit is activated by a digital input.

Setting range

• Setting of digital input (

8.7.26 Digital inputs (4.3.7)

).

• Setting of digital output (

8.7.31 Digital outputs (4.3.9)

).

• Maximum number of pumps in operation.
• Maximum power consumption.

Setting via control panel

• Settings > Secondary functions > Stop function > Reduced 

operation > Go to setting of digital input.

1. Select digital input.
2. Select: Reduced operation.
3.

Monitoring functions

Description

The system has a series of functions that constantly monitor the 
operation of the system. 
The primary purpose of the monitoring functions is to ensure that 
faults do not damage pumps or the system.

Setting range

Dry-running protection (4.4.1)

Min. pressure (4.4.2)

Max. pressure (4.4.3)

External fault (4.4.4)

Limit 1 exceeded (4.4.5 - 4.4.6)

Pumps outside duty range (4.4.7)

Pressure relief (4.4.8)

Log values (4.4.9)

Fault, primary sensor (4.4.10)
