12.4. CONTROL AND ALARMS OPTIONS
The programmable architecture of the controller enables using it in many fields and applications. Before the
operation of the device starts, it is necessary to set the parameters according to specific requirements. A detailed
description of the output operation configuration is given in the following subchapters. The company setting
(default configuration) are the following: outputs P1/SSR1÷ P4/SSR4 related to inputs IN1÷IN4, constantly
switched on control of the ON-OFF type with hysteresis, setpoint values
SP
=
SP1
, optional analogue outputs
(mA/V) 5÷8 switched off.
The
Control and alarms options
menu consists of sets of parameters grouped in the way shown in the table
below (12.4).

Name of parameters set
Description
Output 1 (P1/SSR1)+5 (mA/V), BIN1
÷
Output 4 (P4/SSR4)+ 8 (mA/V), BIN4
4 identical sets of configuration parameters for individual bi-state outputs
(P/SSR) and their related optional analogue outputs (mA/V) and binary inputs
(BIN); a detailed description is given in chapter 12.4.1
Set of PID1 parameters
÷
Set of PID8 parameters
8 independent parameters sets for control of the PID type, the sets can be assi-
gned to different setpoint values; a detailed description is given in chapter 12.4.2
Program 1
÷
Program 4
4 parameters sets for 12-section program control, the programs can be freely
assigned to control outputs; a description is given in chapter 12.4.3
12.4.1. OUTPUT (P/SSR, mA/v) AND FUNCTION INPUT (BIN, F1) CONFIGURATION
Outputs can be assigned to measurement inputs and their mathematic formulas completely independently from
the measured values presented for the measurement channels. For outputs that are not related to any displayed
measurement channels, the
Quick configuration screen
(chapter 11.7) is not available and the operating
parameters of those outputs must be configured in the
Control and alarms options
menu. The device also
enables configuration of the output operation time. If the control/alarm status depends on the real time clock, it is
necessary to program the
Control time
and
Start
and
End of time control
parameters, respectively, and to set the
State of control after power up
parameter to the
No change
value. If it is necessary to start the control for a
strictly defined time (timer function), it is necessary to additionally use the functionalities offered by the program
control (chapter 12.4.3). Moreover, at any time, the user can check the control status using the
[F]
button and the
[Start]
/
[Stop]
and
[F1]
buttons available in the
Quick configuration screen
, as well as the optional function
inputs
BIN
. Detailed descriptions of the configuration parameters and problems related to the operation of the
control outputs can be found in the following table and in the successive subchapters.
