Input Definitions
Schedule initiation is
binary
. Binary initiation sets the desired schedule
number as the total of all the weighted values of BINARY SELECT
inputs for that schedule number. For example, BS1 + BS2 will initiate
Sequence #03 (because 1 + 2 = 3). BS1 + BS3 + BS4 + BS6 initiates
Sequence #45 (because 1 + 4 + 8 + 32 = 45), etc., AND the WELD
INITIATE input is true for that binary combination.
Input Descriptions
This section describes the possible input signals that can be provided to
the control. At the right of each input label, abbreviations are as they
appear on the
I/O Status
screen of the DEP-100S data entry panel.
BINARY SELECT 1 Input
BS1
BINARY SELECT 2 Input
BS2
BINARY SELECT 4 Input
BS4
BINARY SELECT 8 Input
BS8
BINARY SELECT 16 Input
BS16
BINARY SELECT 32 Input
BS32
BINARY SELECT 64 Input
BS64
These inputs select the schedule to be initiated (1 – 99). The
schedule is selected by a combination of these inputs. Each input
has a weighted value (1, 2, 4, 8, 16, 32 or 64). The schedule
initiated is the one selected by adding the weighted values of the
active inputs.
For example, to initiate schedule #4, activate BINARY SELECT
Input #4. To initiate schedule #7, activate BINARY SELECT
Inputs #1, #2 and #4 (because 1 + 2 + 4 = 7).
WELD INITIATE Input
INT
When this input is activated, the weld control executes the schedule
that was selected by the BINARY SELECT inputs.
Setting this input to
0
means the input defaults to open. Setting to
1
means the input defaults to closed.
WELD / NO WELD Input
WLD
This is a Weld input to the control. With this input closed (HIGH =
1), the control is in Weld mode. If this input is open (LOW = 0), the
control is in No Weld mode.
With this input open (No Weld mode), the control will turn on the
NO WELD output (if programmed), no weld current will flow and
the NO WELD fault is issued.
Setting this input to
0
means the input defaults to open. Setting to
1
means the input defaults to closed.
