How to set the alarm value for high temp. system for S&A chiller CWFL-1500 while the alarm value of fiber laser cutter is 30℃? 2018-11-26

laser cooling

S&A CWFL-1500 water chiller has two independent temperature control systems (i.e. high temperature system for cooling QBH connector (lens) while the low temperature system for cooling the laser body). For the high temperature control system of the chiller (for lens cooling), the default setting is intelligent mode with 45℃default alarm value of ultrahigh water temperature. However, for fiber laser, the high temperature alarm is generally activated at 30℃,which may possibly result in the situation that the fiber laser has activated the alarm but the water chiller has not. In this case, in order to avoid this situation, it is suggested to reset the water temperature of the high temp. system of CWFL-1500. Followings are the 2 methods.

Method One: Adjust the high temperature system of CWFL-1500 chiller from intelligent mode to constant temperature mode and then set the required temperature.

1.Press and hold “▲”button and “SET” button for 5 seconds
2.until the upper window indicates “00” and the lower window indicates “PAS”
3.Press “▲” button to select the password “08” (default setting is 08)
4.Then press “SET” button to enter menu setting
5.Press “▶” button until the lower window indicates “F3”. (F3 stands for way of control)
6.Press “▼” button to modify the data from “1” to “0”. (“1” means intelligent mode while “0” means constant temperature mode)
7.Press “SET” button and then press “◀” button to select “F0”(F0 stands for temperature setting)
8.Press “▲” button or “▼” button to set the required temperature
9.Press “RST” to save the modification and exit the setting.

Method Two: Lower the allowed highest water temperature under intelligent mode of high temperature system of CWFL-1500 chiller
1.Press and hold “▲” button and “SET” button for 5 seconds
2.until the upper window indicates “00” and the lower window indicates “PAS”
3.Press “▲” button to select the password (default setting is 08)
4.Press “SET” button to enter menu setting
5. Press “▶” button until the lower window indicates “F8” (F8 means the allowed highest water temperature)
6. Press “▼” button to modify the temperature from 35℃ to 30℃ (or required temperature)
7. Press “RST” button to save the modification and exit the setting.

In respect of production, S&A has invested the production equipment of more than one million yuan, ensuring the quality of a series of processes from the core components (condenser) of industrial chiller to the welding of sheet metal; in respect of logistics, S&A has set up logistics warehouses in the main cities of China, having greatly reduced the damage due to the long-distance logistics of the goods, and improved transport efficiency; in respect of after-sales service, the warranty period is two years.
