keys T1 and T2 (passed four seconds the instrument displays the first parameter of the second

level); for the four seconds following the first release of the key T3 or following the release of

the key T1 or T2 the instrument displays the set value and the LED L3 flashes to indicate that

a configuration parameter setting procedure is running (passed four seconds from the first

release of the key T3 or from the release of the key T1 or T2 without operated with the keys the

instrument automatically turns out from the configuration parameter setting procedure).
To select a parameter of the second level push and release over and over the key T1 or T2 as

long as the instrument displays the label of the desired parameter.
To modify the parameter value push and release the key T3 (to the release of the key T3 the

instrument displays the actual value) and push and release over and over the key T1 or T2 as

long as the instrument displays the desired value (keeping pushed the key T1 or T2 the value

gets decreased or increased more quickly): after the modification push and release the key T3

(to the release of the key T3 the instrument displays the label of the parameter again); for the

four seconds following the first release of the key T3 or following the release of the key T1 or

T2 the instrument displays the set value and the LED L1 flashes to indicate that a configuration

parameter setting procedure is running (passed four seconds from the first release of the key

T3 or from the release of the key T1 or T2 without operated with the keys the instrument

automatically turns out from the configuration parameter setting procedure).
To turn out from the configuration parameters setting procedure keep pushed at the same time

for four seconds at least the keys T1 and T2 or keep pushed for two seconds at least the key T3

or do not operate with the keys for four seconds at least (time-out exit).
ADDITIONAL INFORMATIONS
-

for the whole period of a corrupted memory data alarm the access to the configura-

tion parameters setting procedure is refused

the modification of a parameter value of the instrument has not immediate effect;

to obtain this effect, after the modification turn OFF and turn ON again the instru-

ment

the modification of a parameter value which unit of measure is the hour or the

minute or the second has not immediate effect; to obtain this effect it must not be

executed during the course of the value

the modification of the parameters c1 and c2 value has immediate effect; to avoid

damages to the connected load, it must be executed with the load not connected

the configuration parameters values get stored in a non volatile memory even if a

lack of power supply happens.

4-20 mA SIGNAL CALIBRATION
To correct the 4-20 mA signal derive a milliammeter to the terminal 15 and 17, keep pushed the

key T1 before supply the instrument and release this key before display the acquired quantity

by the device (the instrument displays the indication CAiL).
To correct the 4 mA signal push and release over and over the key T1 or T2 as long as the

milliammeter displays 4 mA (keeping pushed the key T1 or T2 the value gets decreased or

increased more quickly): after the modification push and release the key T3 (to the release of

the key T3 the instrument displays the indication CAiH).
To correct the 20 mA signal push and release over and over the key T1 or T2 as long as the

milliammeter displays 20 mA (keeping pushed the key T1 or T2 the value gets decreased or

increased more quickly): after the modification push and release the key T3 (to the release of

the key T3 the instrument moves to the normal functioning).

time-out link

It establishes for which time interval the instrument must store a connection to a device from

the moment in which an interruption of the connection happens.
c1

-99.9 999.9 points 0.0

acquired quantity value corresponding to 4 mA (§)

It establishes the acquired quantity by the device value corresponding to 4 mA; the instrument

automatically verifies if the value established with the parameter c1 is below the acquired

quantity value corresponding to 20 mA established with the parameter c2.
c2

-99.9 999.9 points 100.0 acquired quantity value corresponding to 20 mA (§)

It establishes the acquired quantity by the device value corresponding to 20 mA; the instru-

ment automatically verifies if the value established with the parameter c2 is above the acquired

quantity value corresponding to 4 mA established with the parameter c1.

---

instrument address

It establishes the address to which the instrument (slave) answers when it is connected to a

serial network with EVCOBUS protocol communication managed from a master (for instance a

Personal Computer).
L2

---

instrument group

It establishes the group to which the instrument (slave) answers when it is connected to a

serial network with EVCOBUS protocol communication managed from a master (for instance a

Personal Computer).
L3

time-out link

It establishes for which time interval the instrument must store a connection to a serial net-

connection happens.
L4

---

baud rate

It establishes the speed with which the data get transmitted in a serial network with EVCOBUS

protocol communication, as indicated:

0 =

1,200 baud

2,400 baud

2 =

4,800 baud

3 =

9,600 baud.

the symbol (§) indicates that the parameter is of the first level.

SIGNALS AND ALARMS

SIGNALS
If the LED L1 is turned ON it means that a configuration parameters setting procedure is

running.
If the instrument displays the indication “CAiL” or “CAiH” it means that a 4-20 mA signal

calibration procedure is running.
ALARMS
If the instrument displays the indication “E2” flashing (corrupted memory data alarm) it means

that there is a corruption of the configuration data in the memory (turn OFF and turn ON again

the instrument: if to the turning ON again the alarm does not disappear the instrument must be

replaced); during this alarm the access to the configuration parameters setting procedure is

refused and the output signal is 0 mA.
If the instrument displays the indication “Conn” flashing (transmission data failure) it means

that: there is a mistake in the instrument-device connection (verify the instrument-device con-

nection integrity), the speed with which the data get transmitted is not proper (verify if the

parameter L4 of the instrument and of the device has value 1), the device is not connected to

the local power supply (verify that the device be connected to the local power supply); during

this alarm the output signal is 0 mA.
If the instrument displays the indication “----” flashing (corrupted memory data of the device

or device not recognized) it means that: there is a corrupted memory data in the device (see

the paragraph ALARMS of the chapter SIGNALS AND ALARMS of the Operating instructions of

the connected device), the instrument does not recognize the device (keeping pushed for four

seconds at least the key T2 the instrument displays the device software code for four sec-

onds); during this alarm the output signal is 0 mA.
If the instrument displays the indication “Err” flashing (probe failure alarm or cold junction/

third wire failure alarm of the device) it means that there is a probe failure alarm or a cold

junction/third wire failure alarm in the device (see the paragraph ALARMS of the chapter SIG-

NALS AND ALARMS of the Operating instructions of the connected device); during this alarm

the output signal is 0 mA.
