25.4.1.2 Control of an external system
with a volt-free control input
Some systems have a volt- free control input. This can be connected
directly to a PoolManager's switch output.
®
If a control input of this kind is available, then it should be used
whenever possible instead of turning the external system's power
supply on and off.
The following figure shows the connection of an external system with
volt-free control input to the switch output OUT 1:
1 External system to be controlled
2 External system's volt- free control input
25.4.1.3 Control of an external system with
external power supply
For external systems with their own power supply (AC or DC), the
power supply can be turned on and off via a PoolManager's
output.
The following figure schematically shows an application example for
switch output OUT 1.
1 External system to be controlled
2 External system's voltage supply input
3 External system's voltage supply
(AC or DC)
4 External system's voltage supply output

Lifespan of relay switching contacts

Depending on application, the lifespan of a relay switching contact
may be limited.
In general, the lifespan of a relay contact is reduced by high switching
currents.
The following guideline values can be used for orientation:

230 V~, 0.5 A, resistive load
Lifespan > 1,000,000 switches


230 V~, 4 A, resistive load
Lifespan > 300,000 switches

Filter pump control

26.1

Safety information

Required user qualification:
TRAINED SPECIALIST or
ELECTRICAL SPECIALIST
Connection, configuration, and start-up of filter pump
control may only be performed by a TRAINED
SPECIALIST or an ELECTRICAL SPECIALIST as
defined in the chapter User qualification.
HAZARD!
Hazard from turning on filter pump
Turning on a filter pump can yield hazards for bathers
(e.g. due to current or suction effects).
Potential consequence: Death or the gravest
degree of injury, heavy material damage.
 Turning on a filter pump is expressly PROHIBITED
 Safety is exclusively in the system operator's
switch
®
 The controller manufacturer disclaims all liability.
26.2

Overview

PoolManager ® offers a control option for filter pumps. Conventional
filter pumps are simply turned on and off. Suitable variable filter pumps
can additionally be set into three different operating modes:

Normal mode
(Normal filter operation)

Eco mode
(Energy saving mode with reduced pump output,
e.g. for night reduction)

Increased mode
(Increase pump output, e.g. for filter rinsing, connecting water
attractions, or solar operation)
PoolManager filter pump control additionally offers the following
®
options:

Multiple flexibly programmable timers

Freely configurable blocking of dosing (pH and disinfection)
depending on the filter pump operating mode

Linking of each filter pump operating mode with an external switch
or push-button

Flexible allocation of up to three relay switch outputs for the filter
pump's various operating modes

Operation of relay switch outputs optionally as potential free
switch or as 230 V~-output

Alternative filter pump control via a 4-20 mA current loop output
(optional)
for all applications in which the safety of persons,
animals, and property is not completely guaranteed
at all times and under all circumstances.
