The configuration menu offers 3 options for configuring the controller which in turn allow certain features of the controller to be set to the user requirements.
1. CONFIGURE JACQUARD JACQUARD TYPE
Three options, selected by using the function keys designated as left and right cursor keys. The required option is accepted by pressing the ‘OK’ function key.
The three options are:-Normal
This is a Jacquard fed by a single data line from the controller. (up to 2688 ends depending upon the Jacquard.)
Split
This is a Jacquard with single data line but allowing the controller to split the Jacquard in two halves, weaving two designs across the loom.
Dual
A double Jacquard with two serial lines allowing two different designs to be sent to each of the jacquards and so two designs to be woven across the loom.
LOOM PIECES
This indicates the number of repeats of a design appearing across the loom so that the correct stopping condition after a given number of repeats of one design can be identified. The count should be entered using the numeric keys and accepted with the return key.
2. CONFIGURE LOOM WEFT OUTPUT POSITION
This indicates the position in the looms cycle when the weft information is to be presented to the loom. See fig 3B/58 on the next page.
On pick at top dead centre
The weft information is output at top dead centre of the pick cycle in which the weft is to be inserted in the shed..
Pre selected at timing signal
The loom provides a timing signal which gives the exact position for the weft information to be output, pre selection indicates that the weft information will be output in the pick cycle before the weft is to be inserted in the shed.
On pick at timing signal
The weft information will be output at the timing signal, provided by the loom, in the pick cycle in which the weft is to be inserted in the shed..
3B/60
Pre selected at off vane
The weft information is output at the off vane, (this is when the shed is closing), in the pick cycle before the weft is to be inserted into the shed.
Pre selected at cross shed
The weft information is output at cross shed, in the pick cycle before the weft is to be inserted into the shed.
Pre selected at zone D
The weft information is output at zone D, (this is when the shed is opening), in the pick cycle before the weft is to be inserted into the shed.
On pick at off vane.
The weft information is output at off vane, (this is when the shed is closing) of the pick cycle in which the weft is to be inserted in the cloth
On pick at cross shed
The weft information is output at cross shed of the pick cycle in which the weft is to be inserted in the shed.
On pick at zone D
The weft information is output at zone D, (this is when the shed is opening) of the pick cycle in which the weft is to be inserted in the shed.
Pre selected at top dead centre
The weft information is output at top dead centre, in the pick cycle before the weft is to be inserted into the shed.
FORWARD
ISSUE 3- 11/95
WEFT OUTPUT POSITION AT REVERSE DETECTION
When the loom stops and then moves in reverse the weft information can be output at any of the positions previously described
:-On pick at top dead centre, etc etc.
WEFT OUTPUT POSITION AT FORWARD DETECTION
The position after a reverse when the weft information for the forward pick is output there are two possibilities.
When forward motion detected
The weft information is not output until the controller detects that the loom has started moving forwards.
At reverse top dead centre
This outputs the forward weft information as the loom moves over top dead centre in reverse, note that weft output position when reverse detected must therefore not be at reverse tdc as this would mean the reverse and forward weft are required simultaneously and this is clearly impossible.
COLOURS BUFFERED IN LOOM
This indicates that the loom accepts weft data in advance of the required position and stores the data internally in a buffer. The user accepts either yes or no using the function keys, if yes is selected the number of colours buffered must be input on the numeric keys accepting using the return key.
PICK FIND FORWARD
If the loom cannot reverse then the enabling pick find forward will allow the controller to accept a pick find forward signal from the loom. The user accepts either yes or no using the function keys, yes enables and no disables pick find forward. If enabled, the number of picks backward that the controller must generate should be entered .
AUTO SHED LEVEL
The loom supplies a shed level signal on the pick before the shed level is required in a pick finding sequence. If this option is selected then shed levelling will not occur until the signal is received from the loom, the shed level performed will be determined by the stop cause which started the pick find sequence and the user selected shed level type for that stop.
SHED LEVEL
The loom does not supply a signal at the required pick and therefore the user must enter manual shed levelling which means that after a given number of picks in a pick find sequence, the controller will shed level. The number of picks before a shed level and the type of shed level are determined by the stop cause and values input by the user for that stop cause.
3B/62
User selects the current setting of the user level, Full access
All possible controller functions available to user.
Limited access
Only some functions presented in a simplified format are available to the user
UPDATE DATE/TIME
The date and time can be set to the correct values when the controller is first powered up or when system configuration is lost. The function keys are used in conjunction with the numeric keys to enter the current date and time in the format shown on the screen for the current date/time.
WARP, WEFT, AUX SHED LEVEL COUNT
Used for manual shed level to determine the number of picks in a pick find sequence after a given stop cause before a shed level is performed.
WARP, WEFT, AUX SHED LEVEL TYPE
Determines the shed level type to be performed for a particular stop type on both automatic and manual shed levelling. The types are selected with the cursor function keys and accepted with the ‘OK’ function key. The available types are,
Mid shed equalisation
Performs a level shed at the mid point of the shed.
Bottom shed equalisation
Performs bottom shed i.e. all ends down.
Normal shed
No equalisation is performed i.e. used to disable shed levelling for a particular stop cause when other stops are required to shed level.
