8.10.9 Examples of time settings for equal overall load
Requirement:
Two machines of the same capacity are to be equally loaded. Versions A, B and C describe the
different possibilities of achieving this requirement.
A detailed description for configuring a clock or timing program can be found in Chapter 8.9.
Variant A: Daily switch between system setpoint pressure pA and system setpoint pressure pB af‐
ter 24 hours
The compressors start with a system setpoint pressure
pB
at 0:00 hours. A timer triggers the
switch between system setpoint pressure
pA
and system setpoint pressure
pB
(local operating
mode:
pA/pB Cycle
local mode).
Precondition The setpoint pressure
pA
/
pB
is configured the same for both machines.
➤ Establish a cycle with the following switching points:
■ Cycle time
pA
: 24 h
■ Cycle time
pB
: 24 h
■ Start
pB
: 00:00AM
Variant B: Equal duty cycle during the day
A timer triggers the switch between system setpoint pressure
pA
and system setpoint pressure
pB
(local operating mode
pA/pB Clock
.
Precondition The system setpoint pressure
pA
/
pB
is configured the same for both machines.
