Precautions on Cooling Capacity and Room
Temperature
The following graph represents the relation between the duty cycle and the cooling
capacity (upper limit of room temperature).
If the value exceeds the cooling capacity line, error No.10 HIGH TEMPERATURE
OF COOLANT occurs. Also, do not operate the product in a room temperature
exceeding the range of 5 to 30ºC shown in the specifications or under a condition
exceeding the laser rated output even within a range shown in the graph.
The duty cycle here means the average value of LAMP INPUT PWR including the
time when the ashlamp is not turned on. The LAMP INPUT PWR is displayed on
the POWER MONITOR screen.
When the duty cycle is less than 100%, the following relation holds.
The LAMP INPUT PWR is 100% and power is "output for 7 sec and then stopped for 3 sec."
(1 cycle: 10 sec)
Duty cycle = 100×7
/
10 = 70%
In the graph, when the duty cycle is 70%, the room temperature is about 25ºC.
To obtain the full cooling capacity, operate the product at a room temperature of 25ºC
or less.
The LAMP INPUT PWR is 80% and power is "output for 3 sec and then stopped for 2 sec."
(1 cycle: 5 sec)
Duty cycle = 80×3
/
5 = 48%
In the graph, when the duty cycle is 48%, the room temperature is about 28ºC.
To obtain the full cooling capacity, operate the product at a room temperature of 28ºC
or less.
