NOTICE!
Incorrect readings due to improper setup
The control unit will not measure voltage correctly if
the 120 V and 480 V inputs are utilized simultaneously.
– Never use both sets of voltage measuring inputs.
Woodward recommends protecting the voltage meas‐
uring inputs with slow-acting fuses rated for 2 to 6 A.
If parameter
rated volt.") is configured with a value between 50 and
130 V, the 120 V input terminals must be used for
proper measurement.
If parameter
rated volt.") is configured with a value between 131
and 480 V, the 480 V input terminals must be used for
proper measurement.
