4.3.5.1.7 Low foam level
When this input is in the “Connected” state, the DPCT
controller will signal a visual indication in the notification
area for Low Foam Level. If the controller is programmed for
Low Foam Shutdown it will initiate the shutdown sequence.
Refer to Section 5.6.8 to program Low Foam Shutdown.
4.3.5.1.8 Proof pressure switch
When this input is in the “Connected” state, the DPCT
controller will signal a visual indication in the notification
area for Proof Pressure Switch. If Proof Pressure Switch
is enabled, the controller requires that this input is
“Connected” before allowing a crank cycle. Refer to Section
5.6.9 to program Proof Pressure Switch.
4.3.5.1.9 Low room temperature
When this input is in the “Connected” state, the DPCT
controller will signal a visual indication on the main display
board for Low Room Temperature. The Common Alarm relay
will also de-energize for remote monitoring of this alarm.
4.3.5.1.10 High room temperature
When this input is in the “Connected” state, the DPCT
controller will signal a visual indication on the main display
board for High Room Temperature. The Common Alarm relay
will also de-energize for remote monitoring of this alarm.
4.3.5.1.11 Interlock
When this input is in the “Connected” state, the DPCT
controller will not permit a start of the engine while in
Automatic mode. This input is typically used in backup style
systems. For example, the Engine Running contacts from
the backup Diesel Engine Controller are wired into this
input. When the Diesel Engine is running, it will lock out the
DPCT panel to prevent it from starting.
4.3.5.1.12 Low reservoir
When this input is in the “Connected” state, the DPCT
controller will signal a visual indication on the main display
board for LOW RESERVOIR. The Common Alarm relay will
also de-energize for remote monitoring of this alarm.
4.3.5.1.13 High reservoir
When this input is in the “Connected” state, the DPCT
controller will signal a visual indication on the main display
board for HIGH RESERVOIR. The Common Alarm relay will
also de-energize for remote monitoring of this alarm.
4.3.5.1.14 Reservoir empty
When this input is in the “Connected” state the DPCT will
record in history when the RESERVOIR EMPTY condition
occurred. The DPCT will signal a visual indication in the
notification area of the user interface touch screen to
indicate RESERVOIR EMPTY.
4.3.5.1.15 Low fuel
When this input is in the “Connected” state the DPCT will
record in history when the LOW FUEL condition occurred.
The DPCT will
signal a visual indication
in the notification
area of the user interface touch screen indicating LOW
FUEL. It will also change the fuel tank graphic on the HOME
screen to indicate a low fuel condition.
4.3.5.1.16 High fuel
When this input is in the “Connected” state the DPCT will
record in history when the HIGH FUEL condition occurred.
The DPCT will
signal a visual indication
in the notification
area of the user interface touch screen indicating HIGH
FUEL and changes the fuel tank graphic on the HOME
screen to indicate a high fuel condition.
4.3.5.1.17 Fuel spill
When this input is in the “Connected” state the DPCT will
record in history when the FUEL SPILL condition occurred.
The DPCT will
signal a visual indication
in the notification
area of the user interface touch screen on the main screen
indicating FUEL SPILL.
4.3.5.1.18 Dump valve
When this input is in the “Connected” state the DPCT
will record in history when the DUMP VALVE condition
occurred. The DPCT will signal a visual indication in the
notification area of the user interface touch screen on
the main screen indicating DUMP VALVE. The DPCT
will delay initiating the crank cycle for three (3) seconds
during which time it will energize the DUMP VALVE relay.
After the three (3) seconds has elapsed the DPCT will
initiate the crank cycle while keeping the DUMP VALVE
relay energized. Once the DPCT has received an ENGINE
RUN signal response it will then de-energize the DUMP
VALVE relay.
4.3.5.2.19 Enable sequential start
When this input is in the “Connected” state and the SST is
programmed, the controller will delay all automatic starting
means for the duration of the programmed SST.
4.3.5.1.20 Relief valve discharge
When this input is in the “Connected” state the DPCT will
record in history when the RELIEF VALVE DISCHARGE
condition occurred. The DPCT will signal a visual indication
in the notification area of the user interface touch screen on
the main screen indicating RELIEF VALVE DISCHARGE.
4.3.5.1.21 Custom input
When this input is in the “Connected” state the DPCT
will record in history when this CUSTOM INPUT condition
occurred. The DPCT will also record in history what the
custom input was programmed as.
