2 Voltage/frequency input
The main board has an input for monitoring the voltage and frequency value.
103 - 104
Input for voltage to be monitored (range 0 -260 Vac).
Verification of the voltage value read by the board:
•
read the voltage to terminals 103 and 104 using a tester:
•
visualise the value of parameter 93.
If the two values do not correspond, make the necessary calibration using the trimmer
shown in Figure 1-1 MAIN BOARD.
N.B.: the value of parameter 93, indicated on display B5, is not updated dynamically.
Update the displayed value using the B6 keys.
