MELODY 1 CONTROL BOARD WIRING
The LS33100 Controller has the following features incorporated in the design
1) UP / DOWN CONTROL - The LS33100 uses constant pressure buttons.
2) ONE SECOND DELAY CIRCUIT – The delay circuit provides a delay of 1
second between pressing the up / down button and the lift operating
3) THE SECOND ONE SECOND TIMER CIRCUIT
The second - one second timer is similar to the fi rst one second delay
circuit. The timer is initiated by the one second delay timer output when
the up / down button is released. If the up/down button is repressed
within 1 second, the lift starts again in the same direction (up or down). If
the up/down button is re-pressed after 1 second, the lift reverses direc-
tion.
4) ANTI-WELD - The up and down relays are connected so that if a relay
contact was to weld, the earth return of the other relay coils is broken and
the lift will not operate until the weld is cleared.
5) FINAL RELAY INTERLOCKING – The way that the fi nal relays are wired
ensures that if the lift is travelling, the other relay coils are isolated. This
means that it is impossible for both up and down relays to operate at the
same time.
6) DIRECTION REVERSAL CIRCUIT – This circuit is comprised of relays
RL11 and RL12 and changes the lift direction.
7) MOSFET CONTROL CIRCUIT - The function of the MOSFET control
circuit is to ensure that the MOSFET makes and breaks the power to the
pump motor and solenoid.
8) ANTI-CREEP CONTROL – When the lift rises it stops in the top position
due to the N/C contacts of the top limit switch going O/C which breaks
the up hold circuit. If the lift creeps downwards, the N/O anti-creep switch
operates causing the lift to rise.
9) LED INDICATORS - Two LEDs are incorporated in the board design to in-
dicate the state of the safe edges. A green LED, if on, indicates that the up
ramp and top limit switch are both closed allowing the lift to rise. A yellow
LED indicates the state of the down safe edge. If the LED is on, the safe
edge or safe edge O/R switch is closed so the lift can be lowered. Note :
- The LEDs are only lit as appropriate after one second when the UP/DN
button is pressed.
Fuses
FUNCTION OF FUSES ON LS33100 BOARD
F1 – 25 Amps Auto-fuse - Controls the power to the pump motor.
F2 – 5 Amps Auto-fuse - Controls the power to the pump solenoid.
F3 – 1 Amp Auto-fuse - Protects the control circuit of the board.
FUNCTION OF FUSES NOT ON LS33100 BOARD
1) 30A Fuse (at end of kicking strip) – To isolate the battery from the
LS33100 board.
2) 5A Fuse (above batteries) - Feed to batteries from Mascot charger.
3) 30A Fuse on negative lead to battery. To protect against earth fault.
To override the remote control enabler
Fitting a link across the 2 block connector (grey and white wires) located on
the control wheel support bracket will override the remote control enabler.
