WARNING
When using a pulse width modulated valve driver, do not
use a carrier frequency between 200 and 600 Hz. If
these frequencies cannot be avoided, consult the fac-
tory. Do not use a pulse current of more than 120% of
that required for full output. Failure to meet the above
conditions can cause severe damage to the valve which
will result in improper system operation.
