Voltage Selector Function

The Soft-Start / Voltage Select Board contains four user settable switches (S1-S4) to
configure the controller for 100 VAC, 115 VAC, 200 VAC or 230 VAC input power. The
voltage selector can only be used with transformers designed to interface with this board.
The location of these switches is shown in Figure 4-1.
Procedure for setting AC voltage selector switches:
1. Turn-off and disconnect all power from unit.
2. Determine the AC line operating voltage that unit needs be set to (Nominal settings:
100VAC, 115VAC, 200VAC and 230 VAC).
3. Use Table 4-1 to set all four of the voltage selector switches to the position indicated
for the desired operating voltage. See Figure 4-1 for additional information.
Example: For 230VAC Operation, Set: S1 to "DN" position, S2 to "UP"
position, S3 to "DN" position, and S4 to "UP" position.

The Voltage Selector can only be used with transformers designed to interface with
this circuit. This Voltage Selector function will not work with off-line supplies.
Damage to unit may result if this function is used improperly.
The Voltage Selector must be setup to match the AC line voltage. Damage to unit
may result if the Voltage Selector is set to a voltage that is different from the input
AC Line voltage.
Disconnect Mains power before opening chassis. Voltage selector settings must not
be changed with Mains power applied to unit.
