514C Product Manual
Current Calibration
Current Calibration is achieved using the BCD switches SW2, 3 and 4 where SW2 represents the
'Tens'; SW3 represents the 'Units' and SW4 represents the 'Tenths'. Thus a 16.5 amp calibration
is achieved by setting switch SW2 to 1, SW3 to 6, and SW4 to 5.
Please note that incorrect adjustment of these switches will cause excessive current to flow
which may cause damage to the motor and the controller. The absolute maximum setting
which can be set is 39.9 amps, this exceeds the Maximum Controller rating in all builds.
