JUMPER SETTINGS.
A.
Dual Voltage Controls
– Models KBVF-23D and KBVF-24D have the capability of
operating standard 208-230VAC - 50/60 Hz, 3-phase motors from either a 115VAC
or 230VAC - 50/60 Hz AC line. The jumpers are factory set for 230VAC - 50/60 Hz.
Use jumpers J1 and J2 on the top PC board to change the voltage input.
FIG. 6A – J1 & J2 SET TO 230 VOLTS
FIG. 6B – J1 & J2 SET TO 115 VOLTS
Warning! Do not change jumper position with AC line connected. Be
sure proper input voltage is applied to control corresponding to
jumper
setting. Connecting 230VAC to a 115VAC control input will permanently damage
control. “115VAC” and “230VAC” labels are provided. Use the appropriate label
to identify the correct input voltage after setting jumpers.
B.
Motor Frequency
– The controls are factory set to operate 60 Hz and 50/60 Hz
motors. For 50 Hz motors, completely remove jumper J1 on lower PC board.
Note:
When the control is set for 50 Hz operation, the DECEL trimpot will
automatically change to adjustable boost. See sec. IX, G, p. 28.
