contains all important matters
related with safety. Please strictly follow.
Signals used in this manual:
A WARNING is given in this document to identify
a hazard, which could lead to personal injury.
A CAUTION identifies a hazard which could lead
to damage to the machine, damage to other
equipment and/or environmental pollution.
A NOTE is used to highlight additional
information, which may be helpful to you but

(2) Installation
Please keep this technical manual well for reference at
any time. Please also give this to other people operating
this machine for reference.
Only the appointed accessory by YORK can be
used, and please ask manufacturer or authorized
dealer to provide the corresponding technical
installation and technical service. Malfunction of
controller or electric shock may be caused from
improper installation of the controlling accessory.
The user is prohibited to maintain the machine by
itself, because electric shock or controller
damage may be caused due to improper repair of
the controller. Please consult the manufacturer
for any repair demand
.
(3) YORK-003 Control Board
YORK-003 control board must be installed on one
stable panel without the accumulative rain or
snow, leaf or other wastes in the host. The
intensive circuit generally passes through the
installation center; also AC220V passes the
control panel. As for the installation location of
outdoor control panel, the principle of power and
signal wires connected separately should be
followed to keep the distance between the control
panel and contactor is above 100mm.
(4) XS08 HMI
XS08 HMI should be installed stably, otherwise, it
may fall down to cause body injury or damage on
controller.
It is required to adopt the specified cable for
power supply. Please do not share the power with
other electric appliance to avoid the danger due
to overloading. It is required to use the fuse or
breaker suited with the working pressure of
controller. Please do not use the wire or fuse
beyond the specified grade.
(5) Earthing
YORK-003 control board and shell of
transformer must be connected with the ground
wire. Please do not connect the ground wire with
the fuel gas pipe, water pipe, or lightning
protection conductor. Electric shock may be
caused if it is improperly earthed. Please inspect
regularly whether the connection between the
earthing wire of controller and earth terminal
and earthing electrode of unit is firm or not.
(6) Operation
Do not press the keypad with the sharper to avoid
damaging the controller. Do not twist or drag the
wire of the controller to avoid damaging the
controller to further malfunction. Do not wipe
the controller with the benzene, thinner or
chemical cloth, otherwise, the component should
be in malfunction. Do not use much strength on
the screen or connection part to avoid the color
variation.
5.2 Initialization Operations
After completing the installation and connection
of YEWS-E HMI, it is required to perform the
initialization operation before putting into
running
.
(1) Situations for Initialization
When the HMI and the control board are interconnected
to form the control system for the first time, it is required
to be initialized.
If the HMI in the interconnected running control system
is damaged, it must be replaced with the new centralized
controller, it is required to be initialized, and it is the same
case for control main board.
If the controller or main board in one control system
