Wrong Sheet
The Wrong Sheet switch is used to sense a jam in the
output register. If this fault occurs, the message “Wrng
Sht” will be displayed, sheet feeding will stop, the Drive,
Pile outputs, and RLY1 will be turned off. Once the fault has
been cleared, the machine can start feeding sheets again by
pressing the Drive Start switch followed by the Sheet Start
switch.
Knife unit in manual mode
If this input is active, the unit will operate in manual mode,
where only a single sheet will be fed into the machine each time
the Sheet Start switch is pressed. If this input is active, the LED
in the make ready key is blinking.
Paper under knife eye (1 to 3)
This input is the photo-eye for the knife unit. If the photo-eye is
covered for more than 1.5 times the last saved knife photo-eye
time, the message ‘KnIFE #’ appears on the large display (1)
and the machine stops.
3.3 24VDC Inputs
Count
The DCT500 can have two Count inputs. The Count Inputs are
referred to as Feeder (FED) and Delivery (DEL). The Feeder
input is used to increment the Total Input Count. The Delivery
input is used to increment the Total Output Count. Some
machines will only use the Feeder input. Machines that use
both count inputs use a sensor at the input of the machine
(Feeder) to sense sheets feeding into the machine and a sensor
at the output of the machine (Delivery) to sense actual com-
pleted sheet output. The difference between the two counts is
called the Waste Count.
Tachometer
The Tachometer input is a high speed input that is used to
sense rotation of the Fold Roll. This input allows the unit to
calculate the speed of the machine, and allow the unit to
determine the length of a sheet being fed through the machine
by counting the number of Tachometer pulses received. Each
tachometer pulse represents a certain distance, see Table 1
Machine Types. The actual distance is dependent on the
machine type selected. The Tachometer Input starts when the
Drive Start switch is pressed. If the tachometer reading is
outside the range of 10 to 230 meters per minute, the unit will
display the message “NO TACH”, and prevent further opera-
tion of the machine. To restore operation, the Drive Start switch
must be pressed.
Four additional 24VDC inputs are provided on the DCT500. One
input is for the Tremat unit and two inputs are for the knife-
folding unit. The remaining input is for the ergonomic pile load
sensor.
Ergonomic Pile Load Sensor
The Ergonomic Pile Load Sensor is an optional sensor that is
installed for special paper loading applications. If the input is
active and the Down Pile switch is pressed, the Pile Down
output will turn on. Once the Ergonomic Pile Load input
changes to the inactive state, the Down output will turn off. At
this time the operator will load paper onto the pile. Five seconds
after the Ergonomic Pile Load input senses the Pile, the Pile
Down output will turn on. This process will continue until the
operator presses the Pile Stop switch.
Thermal
The Thermal input indicates that a motor is overheating. If
this fault occurs, the message “overload” will be displayed,
sheet feeding will stop, the Drive and Pile outputs will be
turned off. Once the fault has been cleared, the machine can
start feeding sheets again by pressing the Drive Start switch
followed by the Sheet Start switch.
