Shutdown Status
Area
Ignitor 1 & 2
Status Area
The main Stop/Reset switch acts as a reset to clear any latched shut downs that have tripped and been detected by the CSC400.
A shutdown configured as a latched shutdown prevents the system from automatically restarting after it detects any
interruption in continuity on the input terminals for the selected shutdown. If a latched shutdown trips, then resets itself, the
CSC400 will detect this, prevent the system from automatically restarting, and alert the user on the LED display (and via
Modbus) as to which shutdown caused the latch out.
All The Shutdown Status Area shows the current state of the CSC400:
"OFF", "ON" (blank), or whether a Shutdown (first-out) is active
(flashing).
All Ignitor 1 & 2 Status Area shows the state of each Ignitor (if enabled):
"ON", "OFF", or "FF" (flame fail). If an Ignitor is disabled, it will not be
displayed.
All The Menu button is used in two ways:
1) To show the Top Menu when the Main Screen is displayed
2) To "back up" by one menu each time it is pressed to a parent menu,
eventually getting back to the Main Screen
All The Select button is used in the menu system to either select an option to
modify, or to select a sub-menu to branch to.
A "selected" option will show a blinking cursor: ">" alternating with " "
All The Up button is used for incrementing values (ie: temperature setpoints)
and moving up the list in the currently displayed menu. Hold the button
down to increase values by larger increments. Release button when
desired value is reached.
All The Down button is used for decrementing values (ie: temperature
setpoints) and moving down the list in the currently displayed menu.
Hold the button down to decrease values by larger increments. Release
button when desired value is reached.
All Pressing the Stop Button will cause the system to stop: power to ignitor
outputs and shutdowns will be shutoff. Valve solenoid power outputs
will be turned off. Pressing the Stop button will also clear any shutdown
and shutdown latch indicators present on the LED display.
Other methods of shutting off the system include:
- Remote Start/Stop in the Stop position (open contacts). Note: 12VDC
power will remain on the shutdown terminals if only the Remote
Start/Stop is opened
- Modbus Remote Stop command
- Shutdown terminals (system will restart automatically if SD terminals
close again and the SD Latch menu option is disabled for the selected
shutdown)
All Pressing the Start button will cause the system to start
Pressing the Start button will also clear any shutdown indicators present
on the LED display.
Other methods of turning on the system include:
- Remote Start/Stop toggled Off, then On again (open contacts, then
close contacts again)
- Modbus Remote Start command
