DIP SW-A. No. 2 This switch allows you to select out of “Constant” or “Only
during operation ” for the cooling water and N2 monitoring.
When “Only during operation” is selected for the cooling
water monitoring, monitoring will be continued for 15
minutes after the pump operation has stopped for cooling
the pump. Note that the N2 purging is recommended to
continue during the pump stoppage as well because it will
reduce accumulation of by-products and corrosion of the
pump.
DIP SW-A. No. 3 This switch allows you to select whether an acoustic alarm
(buzzer) should be sounded or not when a WARNING/ALARM
signal has been generated.
DIP SW-A. No. 4 This switch allows you to select "According to Signal” or
“PUMP STOP” when this switch is moved from the LOCAL
to the REMOTE position. When the former is selected, the
pump is started/stopped in response to the external start
signal. When the latter is selected, the pump is stopped
regardless of the external signal.
[ NOTE ] You can change the setting of No. 3 (Buzzer) and this switch
anytime. When the settings other than No. 3 are changed, the LCD
controller starts counting down from 10 seconds right after the
setting change, which is similar to the situation when the power is
on.
DIP SW-A. No. 7 (dip switch-A No. 7 lets you select whether dilution N
2
gas is
used or not. Set dip switch-A No. 7 to ON when the
production process does not lead to the formation of
reaction by-products in the pump or when the process uses
non-corrosive gases. Then close the N
2
gas selector valve to
save N
2
gas. Be sure always to use the N
2
gas selector
valve and dip switch-A No. 7 in combination.
[ NOTE ] The N
2
gas selector valve is positioned on the right panel when
viewing facing the utility side of the pump.
