VACUUM SWITCH
PIPING
When using commercially available fitting for M5 female screw:
Hold the switch on the port side. Tighten the fitting with a wrench with a
torque of 0.49 Nm or less.
Do not directly hold the switch body when tightening. Do not use a
wrench to any other part than the port section when tightening.
Such handling may cause a breakage of the switch.
SETTING
Two-switch output
a. Place the display selector switch (MODE)
in the"S1" position.
b. Turn pressure setting trimmer 1 (SET1) to
set the operating pressure of switch 1.
c. Place the display selector switch (MODE)
in the "S2" position.
d. Turn pressure setting trimmer 2 (SET2) to
set the operating pressure of switch 2.
e. Place the display selector switch (MODE)
in the "ME" position.
For further precise setting, apply pressure and attain an optimum pressure
level by adjusting the trimmers several times. The setting range of the
switch, adjustable range of the setting trimmer in other words, does not
agree with the rated indication range of the display. Even though the indica-
tion of the display is "0 through 99", the switch can be set at a pressure un-
der 0 or over 99 with the extra margin of a few %FS.
When setting the display selector switch and the pressure-setting
trimmer, be careful not to apply too much force to them. The allow-
able torque for the display selector and the pressure setting trimmer
should be no more than 0.025 Nm.
