CONTROL OPTIONS GUIDE
Soft Start Option (SW1-1):
When this switch is ON, the output ramps up to required power level using phase angle and then switches to burst
fire mode.
Rapid Burst Fire (SW1-2):
When switch SW1-2 is in the OFF position, standard burst fire is used. When in standard burst fire mode, the Burst
Rate trimmer (VR1) is used to set the time bae. The time base is the ON/OFF cycle time, this is variable from 1-30
seconds. When switch SW1-2 is in the ON position, rapid burst fire mode is selected. Two types of rapid burst fire are
supported, single and dual cycle. Single cycle is selected when Burst Rate trimmer (VR1) is fully anticlockwise. Dual
cycle is selected when Burst Rate trimmer (VR1) is fully clockwise.
Offset Option (SW1-3):
When SW1-3 is in the off position no offset is selected for the voltage and current input control signals. When SW1-3
is in the ON position an offset is introduced, this option is selected for 1-5V, 2-10V and 4-20mA control signals.
Voltage or Current Option (SW1-5):
When switch SW1-5 is in the OFF position this selects a voltage control input signal (0-5V, 1-5V, 0-10V, 2-10V).
When switch SW1-5 is in the ON position this selects a current control signal (0-20mA, 4-20mA).
10V Signal Option (SW1-6):
When switch SW1-6 is in the OFF position the control voltage is selected to be 0-5V or 1-5V, depending on the Offset
Option switch (SW1-3).When switch SW1-6 is in the ON position the control voltage range is selected to be 0-10V or
2-10V depending on the Offset Option switch SW1-3.
