5.5 The quick way to set parameters
The general rule is to determine the following before setting parameters:
Which components (pumps, compressors, heaters, fans, alarms etc.) do you
wish to control or regulate with the controller?
Which factors (temperatures or external events) are decisive for controlling
the connected appliances?
How must the factors (inputs) be connected with the control components (out-
puts)?
Are alarm or fault reporting functions to be defined?
Step 1:
Activate required hardware components
Activate the required sensors and analogue inputs / outputs in the
d-level and set them to the desired mode of operation.
Step 2:
Parameterizing the controller blocks
The connected sensors / analogue input are connected with the re-
levant control component via parameters [P11 to P14] and the type
of control determined.
Step 3:
Assignment of output relays / analogue output
The relay outputs / analogue output are connected with the relevant
control or functional components via parameters [P21 to P27].
Step 4:
Assignment of the digital inputs
The digital inputs are connected with the temperature alarms 1 or 2
or with the output relays via parameters [H21 to H25] and [P21 to
P25] A collective fault reporting contact can also be defined.
Step 5:
Configuration of temperature alarms
Parameter s[H1 to H6] and [P21 to P25] are used to determine:
-
the nature of the temperature alarms,
-
assignment to the control components,
-
optional additional functions,
-
connection with the output relays.
Schritt 6: Configuration of a collective fault reporting contact
A collective fault report can be triggered by a temperature alarm [H5
or H6] or a digital input [parameters H21 to H25]. Parameters P21 to
P25] are used to determine which relay is to be switched.
