3.4 Piping

Connect piping firmly. Incorrect piping might cause leakage of supplied or drained fluid to surrounding area and facility.

Use caution not to allow dust and foreign matter to enter the water circuit, etc. during connection of piping.

Securely connect the piping at the piping port with specific wrench when tightening.

Incorrect piping can burst when in service. Use non-corrosive material for fluid contact parts for the circulating

fluid and/or facility water. The use of corrosive materials such as aluminum or iron for fluid contact parts, such as piping, may not only lead to clogging or leakage in the circulating fluid and facility water circuits but also refrigerant leakage and other unexpected problems.

Do not generate a rapid change of pressure by water hammer. Internal parts of the product and/or the piping may be damaged.

It is recommended to use heat insulation to reduce the heat radiation

and absorption to/from customer's piping.

Be sure to wear protective shoes and gloves to prevent injury from

the panel edges.

About offset function

This function controls the circulating fluid discharge temperature with offset.

Temperature offset may occur between the thermo-chiller and the customers device depending on the installation environment. To correct the temperature offset, three types of offset functions are available (MODE1 to 3). The default setting of this function is OFF.

When communication is used

The circulating fluid temperature sent by serial communication is the circulating fluid temperature which is displayed on the thermo-chiller (the circulating fluid temperature after offset).

5.4 Description of the Screen HRL Series 5-30

Example of temperature offset

The discharge temperature of the circulating fluid is 30 o C, but the fluid temperature in the

customers device is 29 o C because of heat radiation during sending of the fluid.

MODE Explanation

MODE1

Control the temperature so that the discharge temperature of the circulating fluid is circulating fluid set temperature + offset temperature. Circulating fluid temperature indicates the circulating fluid discharge temperature.

MODE2

Control the temperature so that the discharge temperature of the circulating fluid is circulating fluid set temperature. Circulating fluid temperature indicates the circulating fluid discharge temperature + offset temperature.

MODE3

Control the temperature so that the discharge temperature of the circulating fluid is circulating fluid set temperature + offset temperature. Circulating fluid temperature indicates the circulating fluid discharge temperature - offset temperature.

OFF Control the temperature so that the discharge temperature of the circulating fluid is circulating fluid temperature set value.

Example of MODE 1

When the offset temperature is 1 o C, the thermo-chiller controls the temperature at 31

o C (circulating fluid

set temperature + offset temperature.) Even if the discharge temperature is 31 o C, the circulating fluid

temperature is 30 o C at the customers device because of 1

o C of heat radiation during sending of the fluid.

Circualting fluid display temperature and communication data is 31 o C.

When the offset temperature is -1 o C, circulating fluid display temperature and the communication data is

29 o C (circulating fluid discharge temperature + offset temperature), and matches the circulating fluid

temperature at the customer's device.

Example of MODE 3

When the offset temperature is 1 o C, the thermo-chiller controls the temperature at 31

o C (circulating fluid

set temperature + offset temperature) Even if the discharge temperature is 31 o C, the circulating fluid

temperature is 30 o C at the customers device because of 1

Pump operation mode

4. Pump operation mode can be set up.

Pump operation mode can be selected from the following three modes:

Pressure control modeOperates to maintain the circulating fluid discharge pressure at the set pressure. This mode is set by default.

The pressure might not rise to the set pressure if the piping resistance in the users device and piping is too small.

Flow control modeOperates to maintain the circulating fluid flow rate at the set flow rate. (However, CH1 flow rate serves as a rough indication.)

The flow rate might not reach the set flow rate if the piping resistance in the users device and piping is too large.

Pump output setting modeOperates to maintain the pump output (rotation) at the set output.

About the control function of circulating fluid discharge pressure This is a function to control the pump output to maintain the circulating fluid discharge pressure within the set pressure. This function is Disabled by default. If this function is Enabled, the control pressure set by this function gets priority over the pressure, flow rate and output set by the pump operation mode. [ ] is displayed on the upper screen when the pump discharge pressure is controlled during operation. (Refer to 5.4.1 Operation condition display on home screen.)

This can be set on Pump operation mode setting screen. Refer to Table 5.4-7 Pump operation settings for details.

KEY-LOCK Prevents all operations other than Run/Stop, Change screen and Alarm reset.

START-UP operation setting Function to restore back to the state prior to power shutdown, after the power supply is restored, when power supply had been cut off due to a power outage.

ANTI-FREEZING Function to prevent freezing of circulating fluid when the operation was stopped during winter time by automatic operation and by heating the circulating fluid with heat generated by pump. Pump automatic running and stopping is repeated to prevent freezing by maintaining circulating fluid temperature at 3C to 5C.

Pump automatically starts operating if the circulating fluid temperature drops below 3C.

Circulating fluid is heated by the pump power generated by pump operation. When the circulating fluid temperature reaches 5C or higher, the pump will stop operating automatically.

WARMING-UP Function to maintain the circulating fluid at the

warming-up setting temperature when operation is stopped during winter time or at night by conducting automatic operation and heating the circulating fluid with heat generated by the pump.

Pump automatically continues operating until the circulating fluid temperature rises up to +2C, which is the warming-up setting temperature.

Pump automatically stops operating when the circulating fluid temperature rises up to +2C which is the warming-up setting temperature.

Pump automatically restarts operation when the circulating fluid temperature drops to -2C which is the warming-up set temperature.
