5-8-3. Coolant circulation unit
Measured values and set values are displayed.
Setting Circulate Pump Control in the system parameter 1
setting screen to Auto activates the following interlocked
operations.
When operation of NVC is started, the circulation pump is
turned ON to start circulation of coolant. (Temperature control,
if it is stopped, is started.)
When operation of NVC is stopped, the circulation pump is
turned OFF and circulation of coolant is stopped. Stopping
circulation of coolant minimizes condensation and operation
time of the freezer.
While circulation is stopped, the coolant temperature setting is
changed to the temperature below and intermittent operation
that repeatedly turns the circulation pump ON for one minute in
about every 30 minutes to prepare for the next operation of the
evaporator.
The setting of temperature is returned to the original setting
when operation of NVC is started.

5-8-2. Bath
Measured values and set values are displayed.
Setting Bath Auto Stop Control in the system parameter 1
setting screen to Auto activates the following interlocked
operations.
Temperature control of the bath is stopped interlocked with
the operation stop of NVC. When the evaporator is also
connected, temperature control of the bath will be stopped in
about 2 seconds after the evaporator is turned OFF.
Interlocked operations above are not made when Bath Auto
Stop Control is set to Manual.
When an alarm occurs in any of other units connected with
the NVC communication cable, “(12)System Alarm” is
triggered and temperature control of the bath is stopped.

When the evaporator is also connected, the circulation pump is turned
OFF in about 2 seconds after the evaporator power is turned OFF to
stop temperature control.
Interlocked operations above are not made when Circulate Pump
Control is set to Manual and manual operation of the coolant
circulation unit only will be made.
When an alarm occurs in any of other units connected with the NVC
communication cable, “(12)System Alarm” is triggered and
temperature control of the coolant circulation unit is stopped and the
circulation pump is turned OFF.
