SECTION 3- CONTROL PANEL OPERATING PROCEDURES
The following is a guide to the operation of the
control panel. Initial start-up of this unit must be
performed by factory trained start-up personnel.
Operation prior to initial start-up by factory
trained personnel will void the warranty.
CAUTION:
All initial installation procedures must be
satisfied before attempting to start the unit.
WARNING:
DO NOT ATTEMPT TO DRY FIRE THE KC
1000. STARTING THE UNIT WITHOUT A
FULL WATER LEVEL CAN SERIOUSLY
DAMAGE THE UNIT AND MAY RESULT IN
PERSONNEL INJURY OR PROPERTY
DAMAGE. THIS SITUATION WILL VOID
ANY WARRANTY.
3.1 THE CONTROL PANEL
The KC 1000 Control Panel has been designed
to provide the operator with all the necessary
information required for operating and
troubleshooting this unit. There are six separate
accessible controls or displays, available to the
operator, (see Fig. 3.1). These are:
1. The Temperature Controller
2. The Annunciator & Function Switches
3. The Combustion Safeguard Controller
4. Water Level Test and Reset Switches
5. On/Off Switch
6. Fault Indicator Light
The following sections will describe the above
components in more detail.
WARNING
CONTROL BOX INTERNALS MUST NOT
BE SERVICED OR ACCESSED BY
OTHER THAN FACTORY CERTIFIED
SERVICE TECHNICIANS. ALL CONTROL
BOX INTERNALS HAVE THE CAPABILITY
OF HOLDING AN ELECTRICAL VOLTAGE
OF 120 VOLTS AC.
3.2 THE TEMPERATURE CONTROLLER
The temperature controller is a PID
programmable controller that utilizes feed
forward and feedback information to accurately
maintain a desired set point. It is the primary
source for programming and viewing operating
parameter settings. It plays a part in the start
sequence and includes other features such as:

3.2.1 LED DISPLAYS
The upper and lower displays each consists of
four, 8 segment LED's (see Fig. 3.2). When
choosing an operating parameter to be changed
or looked at, the lower LED display indicates the
parameter being looked at in the form of a code.
The upper display indicates the parameter's
value. For a complete listing of the operating
parameters, see Appendix A of this manual.
3.2.2 INDICATOR STATUS LIGHTS
The first LED indicator light, "MAN" indicates
whether the controller is in auto or manual
mode, (see Fig 3.2). When lit the controller is in
manual mode and the operator is responsible for
operation of the unit. When the LED is not lit the
controller is in auto mode. In auto mode the
controller is operating the unit from signals
generated by sensors located on the unit or in
the system, or by signals from an energy
management system.
The second LED, "REM", designates whether
the controller is being controlled locally or
remotely, (see Fig. 3.2). When lit the controller is
in remote mode and can accept commands from
an external source via the RS-485 interface.
When this LED is not lit the controller is in local
mode and will respond to whatever the current
internal settings are. All external commands are
ignored.
