SETTING TO WORK

5.3. TEST AND DIAGNOSTIC ROUTINE: SECONDENT

5.3.1. Test of LEDs functionality (Test mode routine)

The "Test mode routine" is booted by keeping "PREP" key (handswitch) pressed at
power on.
During "Test mode routine" X-RAY emission is inhibited.
All LEDs must be ON (except X-ray LED).
Pressing "PREP" key (handswitch) exits "Test mode routine" and automatically
enters in "DVM routine".

5.3.2. Measure of mains voltage (DVM routine)

After having completed or aborted the "Test mode routine" (by pressing the "PREP"
key) the DVM routine (Digital Voltmeter) is initiated.
During DVM routine X-ray emission is inhibited.
The "DVM routine" is a test function used to check the mains voltage value meas-
ured by the Timer. This value is indicated on the operator panel as follows:
1) If the voltage readout is 230 VAC the lower LED and the higher LED are lit (Fig. 1).
2) If V<230 VAC , upper LEDs are lit with two volts per step increment (Fig. 2).
3) If V>230 VAC , bottom LEDs are lit with two volts per step increment (Fig. 3).
