ADJUSTING
(Fig.3)
Turn the range
Adjusting screw to clockwise (+) for increasing
the setting value, and to counterclockwise (-) for
decreasing the setting value.
(Please use the right chart as reference for
adjusting.)
CAUTION
• Do not move the screw other than the Range
Adjusting Screw.
• Do not apply torque that exceeds 0.35 Nm for
adjusting screw. Otherwise it may damage part
of resin case. Then range adjustment may not be
possible.
OPERATION CHECK
Install and calibrate the product correctly and the
check its operation to confirm correct function of
the whole system.
CAUTION
• It can not be used for ammonia refrigeration
system.
• This product is not available for the system which
apply pressure more than 681psi (47bar) because
the rated maximum working pressure of this
product is 681psi (47bar) if the pressure more
than the rated maximum working pressure is
applied to this product, it causes transformation
of characteristics or the destruction.
Operation will become unstable when using
other than sine waves for the power supply. In
this case, proper control may not be achieved.
• To ensure stable operation, sine wave AC power
supply must also be stable.
F.V.S.: Full Voltage Set point
The pressure at which the control delivers 95%
output effective voltage. (R.M.S.(V%))
E.P.B.: Effective Proportional Band
The decrease in pressure below the calibration
set point required to transmit a 45% of effective
voltage. (R.M.S.(V%))
