from the mains and only reconnect when the chair lift is fully working.
The board is sensitive to static charge. To avoid damage, touch a metal
surface on the lift to discharge yourself of static charge but do not
touch the IC chips. Please handle the board with care. Do make sure you
double check the connections to the motor and battery before switching
on. Power up delay.
When the board is first powered there is a 3 second delay. If either
the UP/DOWN controls are enabled the chair lift will not move until the
command is removed, then the chair lift will work. This is a safety
feature, it stops the chair lift moving 0.5 seconds after the power is
applied and the UP/Down controls are enabled.
