Adjust the contrast
In graphic-diaply version is possible to adjust the costrast. To do this:
1. press the Enter and Esc buttons together;
2. holding the two buttons, use UP or Down to adjust the contrast as required (increase or decrease respectively).

WARNINGS: - 230 Vac 50/60 Hz (10/-15%);
- the two 230/24 Vac inputs present on J8 and J12 have the same common pole and consequently will be both 24 Vac/Vdc or both 230 Vac.
Basic insulation between the two inputs;
- for DC inputs, connect the negative pole to the common terminal.
Note: separate as much as possible the probe and digital input signal cables from the cables carrying the inductive loads and the power cables, to avoid
possible electromagnetic disturbance.

WARNING: the 21 Vdc available at the +Vdc terminal (J2) can be used to power any active probes, the maximum current is 150 mA, thermally protected against
short-circuits. To supply the ratiometric 0 to 5 V probes, use the +5VREF (Imax: 60 mA) present at terminal J24.
