SECTION IV
DESCRIPTION OF PARTS
A. CONTROL PANEL
The coin panel assembly consists of the coin operator,
a display board, and the keyboard (touch pad) label.
The coin acceptor is used to acknowledge that the
proper coin has been put through the acceptor. The
display board will just display the time and temperature
in a readable number of letter characters. The
keyboard (touch pad) label is used to input Hi, Low,
or Perm Press selection for the dryer to start.
B. CONTROL AND RELAY PANELS
The control and relay panels are located in the back
of the dryer in the middle top selection. The function
of the control and relay panels is to compile signals
from the computer or the incoming voltage and transfer
the signals to the motor and heat circuit, when the
computer executes these various signals.
C. COIN BOX
The coin box assembly is located below the belt and
right coin panel. It is a good size triangular box. When
a coin passes the acceptor, the optic switch sends a
signal to the computer and the coin then falls in the
coin box.
