The remote on/off terminals 7 and 8, when opened will turn off the ignition module
and valve outputs when opened and reset any latched shutdown that may have
tripped then cleared. Controller will not reset unless shut downs have cleared.
These terminals must be wired to dry contacts of a remote switch or relay when
used. A jumper must remain across 7 and 8 when not in use. When remote on/off
is opened,
will appear on display.
The shutdown terminals 9 and 10 are used to turn off the ignition module when
opened. These terminals are wired to dry contact shutdowns such as level
switches, pressure switches, or any other type of auxiliary shutdown device. If
more than one shutdown switch is used, they must be wired in series. Opening of
any switch connected to shutdown terminals 9 and 10 will shut off the ignition
module and de-energize all 3 valve outputs. These terminals can be selected to
latch or unlatch when shutdown is cleared via the dip switch settings (See dip
switch diagram). Unlatch allows the module to restart ignition when cleared, latch
locks out a restart until a manual reset of the On/Off switch is turned off then on or
the remote reset switch is opened then closed.
The alarm status provides for remote indication of whether the CSC 200 is in a
normal operating mode or if it is in a shutdown state, or turned off either remotely
or locally. Alarm status terminals 11 and 12 are a dry set of contacts. When power
to controller is off, the contacts are open. Contacts are also open when controller
is in a shutdown state (ie. Power failure or shutdown is open).This provides for a
complete fail safe indication of the status of the controller.
The POC (Proof of Closure) terminals 13 and 14 are used when a proof of closure
safety shutdown valve is used. This prevents the starting of any ignition if the POC
switch is opened. This safety feature eliminates the risk of igniting a burner if the
valve is partially open and proof of closure switch indicates open. This is also a
failsafe input as it will not allow ignition to initiate if wire is broken or disconnected.
will appear on the display. A jumper must be installed between 13 and 14 if
this feature is not used.
The terminals 15,16,17 and 18 are to be wired directly to the ACL ignition module.
This provides communication between the two, allowing for a complete combustion
safety control and ignition of burner (See wiring diagram).
