Board functions
The circuit board controls almost all of the functions of the PS100.
• The fuse next to the transformer is for the low voltage (+24V and +5V) part of
the circuit.
• The second fuse is for the motor
• The red led indicates clutch operation
• Led 1 indicates that +5V power is present on the circuit board
• Led 2 indicates that +24V power is present on the circuit board
• The push button will reset the microprocessor IC1
• IC2 supplies power to a modified speed regulator which produces
+ 180V DC - Europe
+ 90V DC - - USA
• IC3 and IC4 are power regulators for the +24V clutch, sensors and button led's,
and +5V for the microprocessor
• ZD1 and R3 to ZD5 and R7 are arranged to provide protection to the
microprocessor from +24V being connected to the wrong terminal
• VR1 controls the motor voltage
• The timer controls the length of time the clutch is energised for
