6.2 HIGH-PRESSURE SWITCH
ADJUSTMENT
6.2.1 General. The high-pressure switch assembly has
an adjustable range from 400 to 4700 psi (28 to 324 bar). If
the pressure setting is to be changed from the standard
factory setting of 1150 psi (79 bar) the blowout disc must
also be changed. To prevent system damage, the pressure
switch setting should not exceed 80 percent of the blowout
disc rating. Table 6-3 lists the blowout discs available and
the maximum pressure switch setting to be used.
