Furnace Controller #7200

#7200 HOT BOX Controller:

The BCS #7200 "HOT BOX" ^©™ Temperature Controller is designed to precisely regulate the temperature inside an electric Heat Treat furnace or an electric Melting Furnace.

A state of the art PID loop artifical intellengence computer accurately holds any temperature from ambient up to 2500 F (with optional high temperature thermocouple). The unit will control either 120 Vac or 240 Vac power up to 30 amps maximum. The temperature in your furnace is sampled 4 times a second and is displayed on the LED readout. The setpoint temperature is displayed on a second LED readout as well. If the thermocouple should fail, the unit turns off power to the furnace for safety.

The computer has a set up mode where it learns about YOUR furnace. This is important because there are a wide variety of furnace construction which can adversely affect precise temperature control. In the learn mode the unit will cycle power on and off to find out how best to regulate the power in your furnace. Once it has learned about it the unit can bring your furnace up to temperature without overshooting or undershooting the set point. This prevents wide fluctations about the set point, called "hunting".

The Model #7200 has the following features:

Temperature Control Range: Ambient to 2500 F.
Output Voltage: 120 Vac / 30 Amps or 240 Vac / 30 Amps.
LED Display: 0.28" Red Color.
Thermocouple: Type K.
Unit Dimensions: 6" Wide, 8-1/2" Long, 6" Tall (Over Handle.)
Unit Weight:
Power Input for Unit: 120 Vac.
Load Control: 2PST 30 Amp Relay. Load Power Switch disconnects power to furnace independently of relay.
Temperature Display: Fahrenheit or Celsius selectable.
Unit Power Indicator.
Load Power Indicator.
30 Amp 2 Pole Main Circuit Breaker.
Wire Connections: 3 Power Input & 3 Power Output, 10 AWG Max. into 3 terminal WEGO Blocks.
Unit Operating Temperature Range: 40 F to 80 F, Non-Condensing atmosphere. Keep unit out of direct sunlight and away from significant heat sources.
Indoor use only.
Comes with 10 Ft Probe Extension Cable. Probe sold seperately.

How To Use It:

Connect the input terminals to the power source you intend to use. Strip the wires back 1/4" and insert into the WEGO terminal block. Tighten the screws to retain the wire. Connect the output terminals that connect to the furnace in the same.

Drill a small hole thru the body of the furnace and insert the thermocouple probe. The probe should extend about 1" into the furnace. Place the probe in a position that won't interfer with normal operation. Connect the probe plug into the back of the unit.

Turn on the unit power, and set the controller for auto-tune. Throw the furnace power switch and let the computer complete a tuning cycle, approximately 10 minutes. Now you can input the set point, and the unit will bring the furnace up to that temperature and hold it there. way. You can change the set point at any time from the front panel.

#7301 12" Thermocouple Probe:

The #7301 thermocouple probe is an inconel covered type K thermocouple, ungrounded. The shaft diameter is 1/4" and is 12" long with a standard OST Male connector (STD size, not miniature). The probe is rated for 2440°F operation.

#7302 18" Thermocouple Probe:

Same specs as the #7301, but is 18" long.

#7303 Thermocouple Extension Cable:

The #7303 Thermocouple Extension Cable is 10 feet long. It comes with Male-Female Standard OST Connectors.
