CUT TO LENGTH APPLICATION
Process
• Run machine.
• Slow when nearing required length.
• Stop at required length and cut.
• Repeat until roll/magazine etc. is empty.
• Stop.
• Manually reload roll/magazine etc. and restart.
Utilise:-
• Output 1 to power machine at normal speed.
• Output 2 to reduce machine speed.
• Output 3 to stop machine and operate guillotine.
Program:-
• Count and Input types to suit sensors used,
• Prescalers to suit measurement units required,
• Reset type to Automatic.
• Output 1:-
- Output type to Batch.
- Preset value equal to number of lengths on roll.
- On-time to zero (latched).
• Output 2:-
- Output type to Count
- Preset value equal to length minus slow-feed length.
- On-time to zero (latched).
• Output 3:-
- Output type to Count.
- Preset value equal to length required.
- On-time sufficient for guillotine operation.
• Relay Condition for each output: to suit machine
operating circuitry.
CONVENTIONS USED IN THE PROGRAMMING TREE DRAWING
(see page 6)
Step through options using Digit 1 key.
Use digit increment keys to set up a value.
To programme the User Text, the left 6 characters are cycled using the keys, and the right 6 characters are cycled
using SHIFT and keys together.
The user characters will cycle in the following sequence:
–, ‘dot’, /, 0 - 9, A - Z, ‘space’
Select displayed option. This may be a parameter or the next menu along the tree.
On pressing at the end of a branch (represented above by being within the box boundary) you are returned to the
previous menu level.
Additional Operations
Escape back one level. All the settings which have been chosen by are retained.
Exit Program mode. All settings chosen by are retained.
VOLUMETRIC DISPENSING /FLUID
BLENDING APPLICATION
Process
• Receive signal from conveyor system.
• Stop conveyor and open valve 1
• Close valve 1 and open valve 2
• Close valve 2 and open valve 3
• Close valve 3 and start conveyor system.
Utilise:-
• External Reset input to receive signal from conveyor.
• All relays at rest to stop conveyor and operate valve 1.
• Output 1 to transfer to valve 2
• Output 2 to transfer to valve 3
• Output 3 to close all valves and start conveyor.
Program:-
• Count and Input types to suit sensors used,
• Prescalers to suit measurement units required,
• Reset type to Manual.
• Output 1:-
- Output type to Count.
- Preset value equal to quantity of fluid from valve 1.
- On-time to zero (latched).
• Output 2:-
- Output type to Count.
- Preset value equal to quantity of fluid from valve 2 +
valve 1.
- On-time to zero (latched).
• Output 3:-
- Output type to Count.
- Preset value equal to quantity of fluid from valve 3 +
valve 2 + valve 1.
- On-time to zero (latched).
• Relay Condition for each output: to suit operating circuitry
for conveyor and valves.
