Notes:
1] Ensure that the power supply voltage is
the same as that on the instrument label.
2] Switch ON the power supply only after
all electrical connections have been
completed.
3] In accordance with electrical safety reg-
ulations, there must be an easly identifiable and accessable power disconnect.
4] The instrument is PTC protected.
In case of failure, return the instrument to
the manufacturer for repair.
5] To protect internal circuits use:
- 2 A
~ T fuse for Relay outputs (220 Vac)
- 4 A~ T fuse for Relay outputs (110 Vac)
- 1 A~ T fuse for Triac outputs
6] Relay contacts are protected with varis-
tors.
In case of 24 Vac inductive loads, use
model A51-065-30D7 varistors (on
request).

FUNCTION
The alarm, once occurred, is
presented on the display until
acknowledged. The acknowledge
operation consists in pressing any
key.
After this operation, the alarm
leaves the alarm state only when
the alarm condition is no longer

LOOP BREAK ALARM (LBA)
When the controller connection to
the sensor is discontinued or
other faults are detected in the
control loop, AL1 alarm becomes
active after a predefined time of
1... 9999 s from the detection of
the failure (see page 37).
When a sensor failure occours,
the LBA interventrion is immediate. The alarm state ceases when
the fault condition is no longer
present.
eIn case of ON-OFF control, the
LBA alarm is not active.

Two tuning method are provided:
• Initial one shoot Fuzzy-Tuning
• Continuous, self learning
Adaptive Tuning
The Fuzzy-Tuning automatically
determines the best PID term with
behaviour respect to the process.
The controller provides 2 types
of “one shot” tuning algorithms,
that automatically are selected
according to the process conditions when the tune operation
is started.

start-up
After the execution of the tuning, the
calculated values are automatically
presented in the PID menu.

Notes
With the keypad locked the commands from digital
inputs and serial communications are still operating
The value of PV is “frozen” at the time the digital input
goes to the close state
The permanent closure forces the chosen stored value.
Setpoint modification is not possible.
The impulsive closure, selects the stored value. Setpoint
modification is allowed. If more than one digital input
is selecting a Setpoint, the last to be activated is the
operating one (see page 43)
When the input is in the on state, the Setpoint is changed
in steps
With ON command the output is equal to the forced
value (see page 28)
The blocking function is activated on closing the command from digital inputs
