Outputs - gefran GFX4 Configuration And Programming Manual

The modular power controller has high flexibility in the assignment of functions to the physical outputs. As a result,
the instrument can be used in sophisticated applications.
A function is assigned to each physical output in two steps: first assign the function to one of internal reference
signals rL.1 .. rL.6, and then attribute the reference signal to parameters out.1 .. out.10 (corresponding to physical outputs
OUT1 .. OUT10).
In standard configuration, physical outputs Out1, Out2, Out3, Out4 perform the heating control function (Heat)
for zone 1, zone 2, zone 3 and zone 4, respectively; value 0 (function HEAT) is assigned to reference signals rL.1 in each
zone, and the following values to the output parameters: out.1=1 (output rL.1 zone 1), out.2=2 (output rL.1 zone 2), out.3=3
(output rL.1 zone 3) and out.4=4 (output rL.1 zone 4).
Physical outputs Out5, Out6, Out7, Out8 are optional, and the type (relay, logic, continuous or triac) is defined
by the order code. In standard configuration, these outputs perform the cooling control function (Cool) for zone 1, zone 2,
zone 3 and zone 4, respectively. In this configuration, value 1 (function COOL) is assigned to reference signals rL.2 in each
zone, and the following values to the output parameters: out.5=5 (output rL.2 zone 1), out.6=6 (output rL.2 zone 2), out.7=7
(output rL.2 zone 3) and out.8=8 (output rL.2 zone 4).
Relay outputs Out9 and Out10 are always present, programmable by means of parameters out.9 and out.10, to
which available alarm signal functions are assigned by means of the four reference signals rL.3, rL.4, rL.5, rL.6 in each
zone.
Standard configuration has the following assignments:
- reference signals: rL.3=2 (function AL1), rL.4=3 (function AL2), rL.5=4 (function AL3) and rL.6=5 (function AL.HB or
POWER_FAULT with HB alarm).
- output parameters: out.9 =17 and out.10 =18.
In this way, the state of output physical Out9 is given by the logic OR of AL1, AL3 in each zone, and the state of output
Out10 is given by the logic AND of AL2, AL.HB in each zone.
Each output can always be disabled by setting parameter out.x = 0.
The state of outputs Out1,...,Out10 can be acquired by serial communication by means of bit variables.
The following additional configuration parameters are related to the outputs:
Ct.1 = cycle time for output rL.1 for heating control (Heat)
Ct.2 = cycle time for output rL.2 for cooling control (Cool)

NOTE: Parameters rL.1, ..., rL.6 for each zone
can be considered as internal states.
Ex.: To assign alarm AL1 to physical output
OUT5, assign rL.1-Zone1=2 (AL1-alarm 1) and
than assign parameter out.5=1 (rL.1-Zone1)
NOTE: continuous COOL OUTPUTS can be assigned codes 0, 1, 64
and 65 only, with cycle time fixed at 100 ms
