5. ADJUSTMENT OF THE MAINS VOLTAGE
MEASURING CIRCUIT
The adjustment of the mains voltage measuring circuit have to be carried out only by qualified
technical personnel when the difference between the tension measured with the volmeter and
the value displayed bi the Timer Iis greater of 4V

5.1. ADJUSTMENT PROCEDURE ON THE TIMER DENSOMAT

Open the cover of the timer and, by means of a
1
precision voltmeter, measure the mains voltage ap-
plied to the terminals X3:4 (live) and X3:5 (neutral).
Start the Test and Diagnostic routine on Timer
2
DENSOMAT by following the instruction given in
this manual on Section C, chapter 5.2 - "Test and
diagnostic routine: Densomat".
3
Run the DVM (Digital Voltage Measure) routine until
the mains voltage is monitored on the display.
Adjust the trimmer R26 on the p.c.b. in order to
4
obtain on the display the same value measured by
the voltmeter (tolerance: ± 1 volt).
5.2. ADJUSTMENT PROCEDURE ON
THE TIMER SECONDENT
Open the cover of the timer and, by means of a
1
precision voltmeter, measure the mains voltage
applied to the terminals X3:4 (live) and X3:5 (neu-
tral).
Start the Test and Diagnostic routine on Timer
2
SECONDENT by following the instruction given in
this manual on Section C, chapter 5.3 - "Test and
diagnostic routine:Secondent".
3 Run the DVM (Digital Voltage Measure) routine until
the mains voltage is monitored by the LEDs.
Adjust the trimmer R26 on the p.c.b. in order to
4
obtain on the operator panel the same value meas-
ured by the voltmeter (tolerance: ± 2 volts).
