RECOMMENDATIONS FOR THE INSTALLATION
• The input signals conductors shall be positioned throughout the
factory separate from the output and the power supply
conductors, in grounded conduits if possible.
• All electronic instruments must be powered by a clean mains
supply, proper for instrumentation.
• It is strongly recommended to apply RC'S FILTERS (noise
suppressor) to contactor coils, solenoids, etc.
• In any application it is essential to consider what can happen when
any part of the system fails. The controller features by themselves
can not assure total protection.
ELECTRICAL WIRING
Fig. 3a and Fig. 3b: shows the electrical connections.

Sensor Input Connections
Fig. 3b – Input wiring, outputs, power supply and serial communiction
connections
The input types 0~20 and 4~20 mA are not available in the
controller’s standard model, although shown as an option at the
Type
parameter. These inputs are only available in some custom
models.
The models with 0~20 and 4~20 mA inputs do not accept 0~5 V and
0~10 V inputs types.
DESCRIPTION OF THE PARAMETERS
OPERATION LEVEL
To access the operation level parameters, press the P key until the
desired parameter is displays.
Indicação de PV
(Visor Vermelho)
Indicação de SP
(Visor Verde)
PV and SP indication - The upper display shows the
current value of PV. The lower display shows the control
SP value.
(trl Control Mode -
avto - Means automatic control mode.
Man - Means manual control mode.
(bumpless transfer between automatic and manual control
modes).
PV Indication
(Red Screen)
MV Indication
(Green Screen)
Manipulated Variable 1 Value (MV) - The upper display
shows PV value and the lower display shows the
percentage of MV1 applied to the control output. When in
manual control, the MV1 value can be changed. When in
auto mode the MV value can only be viewed.
To distinguish the MV1 display from the SP display, the
MV1 is shown flashing intermittently.
PV Indication
(Red Screen)
MV Indication
(Green Screen)
Manipulated Variable 2 Value (MV) - The upper display
shows PV value and the lower display shows the
percentage of MV2 applied to the control output. When in
manual control, the MV2 value can be changed. When in
auto mode the MV value can only be viewed.
To distinguish the MV2 display from the SP display, the
MV2 is shown flashing intermittently.
E pr Enable Program. Selects the ramp and soak profile
program to be executed.
0 - does not execute program
1 to 20 number of the program to be executed
With enabled outputs (RvN= YES), the program starts
right after the program is selected.
p.seg Screen for indication only. When a ramp and soak program
is active, this parameter shows the number of the segment
under execution, from 1 to 9.
t.seg Screen for indication only. When a ramp and soak
program is in execution, it shows the remaining time to
the end of the current segment, in units of time
configured in the Pr.tb parameter.
rvn Enables control outputs and alarms.
YES - Outputs enables.
NO - Outputs not enabled.
