according to the following relationship: °F = (1.8 x °C) + 32.

Example: “Lo.E”=-50°C ⇒ “Lo”=-58°F; “Hi.E”=+760°C ⇒ “Hi”=+1400°F,

means that the new measuring range becomes -58° to +1400°F. The

data to be entered in the displayed scale can be calculated either by

means of the above mentioned “°F” relationship, or using the data of the

relevant measuring range (see chapter “Technical Features”, paragraph

“Inputs temperature” on the previous page).

SP.1/SP.2 : menu to select the programming of the set-point parameters.

tYP : selection of the type of control.

oFF : signalling of the abnormal condition. The relay is activated when

a burn-out condition occurs or the measurement is outside the electrical

range (displaying and blinking of the measured value or displaying of the

“EEE”/ “-EE” message).

Note: by selecting this function the “Lo.S”, “Hi.S”, “SP.1”, “HYS” param-

eters are not active.

do : down/low alarm set-point. The relay will be activated when the

measured value goes below the set-point value.

uP : up/high alarm set-point. The relay will be activated when the

measured value goes over the set-point value.

d.do : alarm set-point similar to “do”, but with alarm inhibition eventually

present when MDI40 is turned on. The control starts only after the first

condition of non-alarm has been signalled.

uP.L : up/high alarm set-point with latch function.

The alarm functions as per “uP”, but the alarm can be reset only manually

when the F key is pressed for at least 2 seconds during the measuring

phase.
