MOUNTING
For a proper mounting, take note of the attached indications.
Be sure that the conditions of use (voltage of power-supply, environment temperature, humidity) are inside the indicated limits.
Do not overload the relay-output, keep inside the indicated limits.
WARNING: the instrument is not protected from overloads: so it is necessary to give the output the suitable protections; besides
that, according to the source of power-supply, find a protection able to limit the quantity of current absorbed by the instrument
in case of failure.
CONFIGURATION
There are two Levels of configuration (Level 2 is protected by Password):
Level 1
Push and at the same time for 4 seconds at least: the symbol "PA" appear on the display.
Push or to select the parameter to modify at Level 1.
Push and or to modify the selected parameter.
Level 2
From Level 1 push or to select the parameter "PA".
Push and or to set "-19".
Push and at the same time for 4 seconds at least: the first parameter of Level 2 will appear
on the display.
Push or to select the parameter to modify at Level 2.
Push and or to modify the selected parameter.
How to leave "Configuration"
Push and at the same time for 4 seconds at least; or wait for 50 seconds at least without
operating on the keyboard; or try to switch the power-supply off and then, switch
it on.
PROGRAMMING OF THE WORKING TEMPERATURE
In normal operating conditions the instrument displays the value read by the probe.
Push and release the key
to display the actual setpoint value: the led "out" flashes to indicate that a procedure of setpoint programming
is on run; to change the value, operate on the keys or within 4 seconds since the pressure on the key .
The exit from the procedure of programming of the working temperature can be obtained just not pushing any key for 4 seconds at
least (exit for time-out) or pushing and releasing the key .
SIGNALS AND ALARMS
The led "out", when lighted, indicates that the output is activated; if it is flashing it indicates that a modify of the setpoint value is running.
"E0" flashing on the display and buzzer beeping intermittent means one of the following defects: not proper kind of probe, defective probe,
wrong connection or temperature outside the limits permitted by the used probe; check the value given to the parameter /0, the
connection between instrument and probe and its functioning (the output is deactivated).
"E2" flashing on the display and buzzer beeping intermittent: failure of memorised configuration-data; try to switch the power-supply
off and then, switch it on (the output is deactivated).
"EOC" flashing on the display and buzzer beeping intermittent indicates a cold junction compensation failure (the output is deactivated).
"tun" flashing on the display alternated to the measured temperature value indicates that a "Auto Tuning" function is on run.
"---" flashing on the display and buzzer beeping intermittent indicates that the "Auto Tuning" function is failed (the output is deactivated).
If the display indicates a proper value alternated to the signal "AL1" and the buzzer beeps intermittent, it means that the temperature read
by the probe is off the limits previously set in parameter "A1".
