4.9 Temperature Controller (CAL 9900)
Programmable Set Points. The Programmable Digital Readout Temperature Controller has two set
points that are programmable. Set point one (SP1) is the process temperature; set point two (SP2) is the
standby/interlock temperature. The temperature selector switch determines which set point is activated.
Process Temperature (SP1). The process temperature determines the temperature of the flowing solder
during the rework and soldering cycles. The controller is connected to a thermocouple located at the
bottom of the solder pot. The actual temperature contacting the bottom of the printed circuit board is
approximately 10
°
F less than the process temperature, which is factory set at 500
°
F.
Standby/Interlock Temperature (SP2). The standby/interlock temperatures are the same
temperature. The standby temperature minimizes oxidation by automatically reducing the temperature
when the module is not being used. The purpose of the interlock temperature is to prevent the pump
motor from operating until the solder reaches a molten condition. SP2 is factory set at 70
°
F less than the
process temperature (500
°
F - 70
°
F = 430
°
F).
To Change SP1 or SP2 –
Follow These Procedures
•
SP1 Temperature:
1. With the power and reset switches on,
press the *key and the SP1 setting will flash.
2. By holding the *key down and pressing the
▼
and
▲
keys, the SP1 setting may be changed.
3. When the keys are released, the display automatically returns to actual solder temperature.
•
SP2 Temperature
1. With the power and reset switched on, depress the “P” key with a pointed object. The digital
display will show numbers with a decimal point and the number to the right of the decimal point
will flash.
2. Use the
▼
and
▲
keys to bring the flashing number to 2 at the right side of the decimal point.
3. Press the *key to change the left side of the decimal. Press the
▼
and
▲
keys to set the
differential temperature (range available is 0 - 99
°
F).
4. Press “P” to lock in memory. Display will automatically return to actual solder temperature.
