Explanation of Set Items
(1) The list above shows the default values of standard settings.
(2) This pump gives the following two types of WARNING and ALARM signal.
(a) When the number of set value is one and the pump is to be stopped at a certain
time
The pump displays N
2
Purge Gas if DRP N2 purges gas becomes lower than the
WARNING set value of 0.5L/min and this condition continues for more than the
WARNING set time of 5.0 sec. If the purge gas flow rate is not corrected and the
ALARM set time has passed 180 seconds, ALARM will be given and the pump will
stop automatically. The same applies to N
2
FLOW OPTION , WATER FLOW
and DRP PUMP TEMP .
Also set items include flow rate set value and set time.
(b) When values can be set individually to WARNING and ALARM
The pump gives DRP CURRENT WARNING if the motor power has exceeded
the WARNING set value of 13.5A (HR90) and this condition continues for more
than WARNING set time of 10 sec. If the ALARM set value of 15.5A (HR90) is
exceeded for the ALARM set time of 10 seconds, ALARM will be given and the
pump will stop automatically. Set items include four: WARNING set value and set
time and ALARM set value and set time.
(3) If the alarm set value is 0, the item will not be monitored.
(4) In the item of temperature, the initial set value (H) is the alarm set value. The next
set value (R) is the READY signal set value when temperature rise is completed. The
third set value is used when controlling the heater using this input. Temperature is
controlled within the range of set temperature 3 C.
(5) Auto purge delays the time of closing the N2 purge gas valve when stopping the pump.
Enter delay time.
(6) Set the baud rate according to the equipment connected when RS485/232C
is used. The baud rate is 9600bps as standard, but it can be changed to
2400bps or 4800bps if required.
(7) The address is the No. of the branch-wired pump when RS485/232C is used. Up to
maximum 16 can be branched.
(8) Start check sets a timing to issue the signal of start check. In the case of 1,
the signal of start check is issued by confirming that the pump is rotating
at the specified revolution. In the case of 2, the signal of start check is
issued one second later when start switch of the controller is pushed. In
addition, when intermediate revolution and rated revolution are same
(DRP_INV frequency / MBP_INV frequency), the signal of start check is
issued one second later when start switch of the controller is pushed
regardless of start check = 1 or 2.
- When the temperature of the pump is low, and the
process is done, the process gas is cooled in the pump.
- Driving the pump because a sublime material
adheres in the pump according to the kind of the gas
might become impossible. Please confirm Ready signal
of the temperature of the pump to avoid such trouble.
- Ready signal is Pin.14 of (2.4.2 Wiring for remote
control)
- If the temperature of the pump rises up to the preset
temperature, Pin.No14 and No19 close.
- The temperature of Ready signal of each model of has
been decided. However, the object model becomes only
HR series.
