POWER ADJUSTMENT
The 240 VAC theta controller is calibrated for a nominal 230 to 240 VAC line voltage;
in certain countries, line voltages of 210 to 220 VAC may be encountered and the dip
switch can be set to provide full output current of 10 amps even with the reduced line
voltage.
Note: This controller cannot be converted to operate on 120 VAC line voltage.
Hazardous voltage. To avoid risk of electrical shock, disconnect the power cord
to the theta controller. Do not remove the cover. No user serviceable parts
inside.
A CCESSING THE D IP S WITCHES
Dynojet recommends you set the dip switches at the time of installation.
The two dip switches are the only adjustments that can be altered. Be sure not
to damage any other parts on the circuit board. Do not attempt any other
adjustments.
1 Access the dip switches through a hole in the bottom of the theta controller.
2 Use a small screwdriver to set the dip switches for the desired line voltage.
Power Line Frequency Adjustment—The theta controller is shipped with the dip
switch set for 60 Hz. In some cases, the dip switch is set based on the country it is
shipping to. However, you will need to determine the correct line frequency and set
the switch accordingly.
60 Hz Power Line Frequency Adjustment—For all of North America, this switch
should be set to the 60 Hz position. In Japan, there may be either 50 Hz or 60 Hz
power line frequency; determine the correct line frequency and set the switch
accordingly.
