Sets the monitoring mode for the cooling water and N2:
"Always" or "During operation only."
In the mode "During operation only" for the cooling water, the
monitoring continues for 15 minutes after operation stop for
cooling the pump.
It is recommended that N2 purge should be continuously
active during operation stoppage to reduce by-product
accumulation and corrosion in the pump.
Dip switch-A No. 3 lets you select whether an acoustic alarm
(buzzer) should be sounded or not when a
WARNING/ALARM signal has been generated.
When the toggle switch is moved from the LOCAL to the
REMOTE position, dip switch-A No.4 lets you select "PUMP
START/STOP
(According to Signal)" or "PUMP STOP Regardless of
External Signal (PUMP STOP)".
can change always. When parameter setting of the dip switches,
other than dip switch-A No.3 (BUZZER), is performed, the LCD
controller counts down 10 seconds, the same as at the power on
state, right after the completion of the parameter setting.
Dip switch-A No. 5 lets you select "ALTERNATE Signal
(START Signal ON/OFF)" or "MOMENTARY Signal (2 types
of signal: ON or OFF)" for pump start and stop under external
signal control.
Dip switch-A No. 7 lets you select whether dilution N2 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 N2 gas selector valve to
save N2 gas. Be sure always to use the N2 gas selector
valve and dip switch-A No. 7 in combination.
