16.3 Outputs
In this menu, the signal type and the minimum speed can be adjusted for each indi-
vidual relay of the controller and the external modules.
Î
In order to make adjustments for a relay, select the corresponding menu item
by pressing button
➄
.
For each relay, the signal type and the minimum pump speed can be adjusted.
The signal type determines the way speed control of a connected pump is effected.
The following modes are available:
Adapter = Speed control signal via a VBus
®
/ PWM interface adapter
0-10 V = Speed control via a 0-10 V signal
PWM = Speed control via a PWM signal
Standard = Burst control (factory setting)
With the signal types Adapter, 0-10 V and PWM, the relay itself is not involved in
speed control. A seperate connection for the corresponding signal will have to be
made (see fi gure).
If PWM is selected, the channels Output and Profi le appear. In the Output chan-
nel, one of the 4 PWM/0-10 V outputs can be selected. In the Profi le channel,
different characteristic curves corresponding with the pump in use can be selected
(see page 74).
In order to reduce the number of switching processes for high-effi ciency pumps,
the controller is equipped with a relay overrun function that automatically comes
into effect when the speed control signal is not issued by the relay itself. The cor-
responding relay will then remain switched on for an hour after the switch-off
conditions are fulfi lled.

Note:
When the minimum pump speed value adjusted in the Outputs menu
differs from the minimum pump speed adjusted in an optional function
that uses the same output, only the higher value will be come into effect.
Note:
If PWM, Adapter or 0-10 V is selected for an output, the adjustment range
for the corresponding minimum speed will extend to 20 … 100 %.
If a Laing pump is used, the minimum speed must be set to at least 25 % ac-
cording to information from the manufacturer.
