Figure 3-3 Control Connections
This feature allows the power level of the system to be controlled from a remote
location or device. This is accomplished by applying a 0-5 VDC or 0-20 mA signal
input from a remote source. This feature is not available when the ‘Temperature
Controller’ option is installed. If this feature is desired use the following procedure:
1. For a 0-5 VDC input, connect the source to TB 100 pins 16+ and 17-.
2. For a 0-20 mA input, connect the source to TB 100 pins 16+ and 17-. Also
install a 250 ohm resistor across terminals TB 100 16+ and 17-.
