Control output
The two control outputs (A4 and A5) are identical in terms of parameterization.
In most heating circuit programs, the two control outputs are already used to control the mix
-
er and can therefore not be used for other applications.
In this menu, the parameters for the functionality of the selected control output are adjusted.
As analogue output, a voltage of 0 to 10 V can be output, scaled in 0.1 V steps.
In the mode PWM, a digital signal with a frequency of 1 kHz (level approx. 10V) and a variable
duty cycle of 0 to 100% is generated.
In an active state, a control output can be enabled by an assigned output that is defined by
the chosen program.
Example: control output 4 is set to mode PWM 0-100 and
assigned to output 1 (= FS)
Choices „Function“:
5V supply, 0-10V output, PWM output, error message, error
mess. inv.
Off
Control output deactivated, output = 0V.
5V
Voltage supply, output = 5V
0-10V
PID-regulator, output = 0-10V in 0,1V steps
PWM
PID-regulator, output = duty cycle 0-100% in 1% steps
Error message, Error
message inverse
With function control activated and an error message in the sys
-
tem status (sensor interruption, sensor short circuit or circula
-
tion error) the control output will be set from 0V to 10V in mode
Error message
(if
inverse:
from 10V to 0V). An auxiliary relay
can be connected to the control output which forwards error
messages to signal indicators (LED-indicators, acoustic signals
etc.)
