ON/OFF control
The static
characteristic
of a relay controlled
by an ON/OFF
algorithm is shown on
the left.
PID control
The relationship
between PID input and
output when both
integration and
differentiation are
switched off is
illustrated on the left.
PID-control internal
structure is shown on
the left figure.
Alarm output control
The static
characteristic
of an alarm relay is the
same as for ON/OFF
control.
Alarm time
characteristics
(referenced to
ALt1
,
ALt2
,
ALt3
) are
illustrated on the left.

Input hardware selection
To be completed BEFORE installation!
♦
Insert 2 flat-tip screwdrivers in the slots
located on both sides of the front protection
cover (1).
♦
Gently press the side plastic walls outwards
in order to remove 2 fixing pins (2) from their
slots (3) and then open the cover (1) rotating
it up.
♦
Find the input jumper located on the right
side of the terminal.
♦
Place the jumper bridge in UP position for
T/C or in DOWN position for Pt100 input.
Programming procedure
♦
First go to Level 2 and set
LC"
to
0000
.
♦
From Level 1 (User level) press
SET+
keys for ~5s to enter Level 3.
♦
Set input type by selecting it from Table 1.
♦
For analog linear input, set display value for
LOW input range (-1999 to 9999).
♦
For analog linear input, set display value for
HIGH input range (-1999 to 9999).
♦
For analog linear input, set decimal point
position (0000, 000.0, 00.00 or 0.000)
♦
Set LOW set-point limit
(within PV range, resolution and units).
♦
Set HIGH set-point limit
(within PV range, resolution and units).
♦
Select AL1 alarm mode
(2-digit code from Table 2, '
Alarm modes
').
♦
Set AL1 alarm ON delay time [mm.ss]
(99.59: continued action, 00.00: flicker alarm).
